Heating batteries - which is better for a private house: a comparison of the advantages and disadvantages of radiators of different structures from different metals

If you need to choose the heating batteries, which is better for a private house - the answer to this question can be obtained by relying on a comparative analysis of the basic technical characteristics. Each of the varieties of radiators is characterized by individual parameters, but the principle of their installation is single. At the selection stage of such products, it is necessary to correctly calculate the dimensions. If this is not done, the effectiveness of the batteries will be low.

Radiators for a wooden house. Species, characteristics and dignity

When choosing heating devices pay attention to 2 main criteria:

  • design;
  • Type of material.

When organizing water heating, sectional and tubular radiators are considered for a private house. They differ in efficiency, convenience of operation. Considering the varieties of heating devices, the object area should be taken into account. If it is incorrect to determine the heat transfer, in the future the room will be well heated. And there is no possibility to correct the situation by increasing the size of the batteries.

Radiators of the system of autonomous heating are made of metal. Depending on the type of material, the properties of such products are changing. They can be characterized by different levels of strength, plasticity, heat transfer. The batteries for the house are different at the service life, i.e., not all varieties are equally well withstanding constant contact with water.

How to choose heating radiators for a private house

Sectional and tubular

Both options are distinguished by sufficient efficiency. However, if you install sectional appliances in a wooden house, then with the slightest changes in the operating conditions or parameters of the heating system, you can change the effectiveness of the batteries. This is due to their design: radiators consist of individual sections that are hermetically connected to each other, forming a full-size product. When it is necessary to reduce the heat transfer or, on the contrary, increase this indicator, the number of compound elements of such devices changes.

Another advantage is the ability to adjust the temperature. For this, the thermostat is envisaged. It allows you to control the intensity of heat transfer, prevents overheating of products. If the question is solved, what radiators choose, pay attention to the appearance of products. So, section radiators are considered more attractive. Each of the sections has a lamellar design. This type of batteries can fit into any interior.

When choosing radiators, tubular analogues are considered. Unlike sectional, such products are one-piece design. They consist of pipes that were pre-bent. Depending on the dimensions of the heating devices of this type, heat transfer is changing. However, it is impossible to influence the ability of batteries to give heat. Increase or decrease the size of such radiators will not work, since they do not understand. In appearance, tubular products are somewhat inferior to sectional counterparts.

Panel and lamellar

If the sectional and tubular battery designs are more common, then data 2 products are less common. For example, panel heating devices are a rectangular box, which is manufactured by welding ribbed sheets. The presence of edges allows you to increase the area of ​​heat transfer.

Outside, this design resembles a closed box. Inside batteries are p-shaped profiles that connect the ribbed panels. This allows you to accelerate the heat exchange between the coolant in the pipe of the heating system and the outer surfaces of the radiator.

The average withstand pressure is 8 atm. The disadvantage of panel batteries is considered sensitivity to pressure drops. Inside the design, 1-3 heating plates may contain, from which the speed of heating the ribbed panels will depend on, and at the same time the efficiency of radiators.

By design, the lamellar batteries differ significantly from panel analogs. However, the same principle of heating is a convection method. For this reason, the heating is unevenly: in the upper part of the structure, the temperature is higher. They consist of horizontally oriented pipes, which are connected to the plates located in the vertical plane. Such radiators are one-piece design. It is impossible to change their dimensions after installation, so it is necessary to determine the heat transfer level at the stage of the selection.

The advantage of lamellar radiators is a large surface area. This allows you to increase the heating rate of air in the room. In addition, the radiators of this species are considered universal: they can be installed for heating in a private house and apartments with a centralized system. Additionally, a protective cover can be provided. It is used to improve the appearance of the product.

Panel and lamellar radiators

Cast iron devices are a classic version of radiators. They are distinguished by reliability, long period of operation, strength, resistance to temperature differences, hydrowards. In addition, the cast iron is characterized by high heat transfer, which allows you to quickly warm the room. There is also no resistance to corrosion formation. With regular contact with water, such products do not lose properties.

However, as cast iron batteries are gradually overshadowed: thighs are formed on the interior walls, which contribute to a decrease in the lumen of pipes. This leads to a decrease in the effectiveness of such devices, since the coolant warms the walls longer, the thickness of which increased. Cast iron batteries refer to a group of sectional products. This means that if such a need arises, you can increase the number of sections.

When the heating system with cast-iron devices begins to be operated, it is necessary to prepare for high heat transfer rates. Radiators are quickly heated. However, they are also rapidly cooled, which does not allow to maintain the temperature in the room for a certain period after disconnecting the heating system. Modern models of cast-iron batteries are often acquired to improve the interior, because they are made with decor - decorated with an artistic casting. Outdoor models are in demand.

Bimetallic analogues are harder. They are made from metals of different types: iron alloy and aluminum or aluminum and copper. This allows you to improve the design properties. So, thanks to the inner layer, high reliability of the device is ensured. This makes it possible to withstand the pressure of different values, resist the effects of temperature drops. The outer layer is made of aluminum. Due to this, high heat transfer is provided.

Due to the combination of materials, such radiators are considered the most effective. In addition, they can be installed at facilities with different types of heating system: centralized, autonomous. These batteries have only 1 disadvantage - high cost.

Cast iron or bimetallic heating radiators for a private house

Aluminum or steel

Due to the high intensity of heat transfer, aluminum models occupy the upper positions of the rating of radiators. They quickly heat up, slowly cool. Sectional radiators are often manufactured from aluminum. They are ease, attractive appearance, simplicity of installation. In addition, aluminum heating radiators are relatively inexpensive, which contributes to the growth of their popularity.

However, there are more deficiencies in such products compared to analogs. So, they do not differ resistant to the effects of aggressive substances contained in the coolant. This significantly reduces the service life of radiators. As a result, it may be formed if the metal is thinned. Additionally, water is often seeping on areas of threaded connections.

Due to the high heat transfer, the upper part of the design warms up faster and characterized by a significant temperature. At the bottom of the battery is cooler. This is due to the physical process: warm air rises to the ceiling.

Steel analogs have a number of advantages:

  • relatively low weight, due to which the installation is facilitated;
  • High thermal conductivity, which, along with the presence of a thermostat, reduces utility costs, since it is possible to more accurately adjust the air temperature in the room;
  • continued operation;
  • Wide selection of models.

The shortcomings of steel batteries are more than the analogues. So, such devices are subject to corrosion. If the heating system is triggered, this not only contributes to the violation of its work, but also accelerates the rusting process of pipes. Due to the roughness of the internal surfaces, the lumen of the communications is gradually reduced, which passes the coolant. This helps to reduce the efficiency of radiators. To increase the service life of such devices, it is necessary to regularly maintain the system - to perform it with flushing.

General recommendations for installation

When you need to choose the battery, you must first determine the type of heating system: autonomous, centralized. From this will depend on the load on the instruments. Additionally, the area of ​​the heated object is determined. The number of sections will depend on this parameter: the greater the room, the larger the radiators should be.

At the same time, the intensity of heat loss is taken into account. To avoid fast air cooling in the room, you need to correctly place the batteries. They are installed near each opening in the wall. Then warm air is less intensively removed from the room.

Rules for the location of radiators

When designing the heating system, it is not enough to determine the power of the instruments. It is important to arrange them in accordance with the rules. Main errors during installation, which lead to a decrease in system efficiency: uneven heating of air in rooms, essential heat loss. Recommendations for the installation of radiators:

  • The most suitable place in the room is under the windows: it is better to have a battery in the center of the opening, the width corresponds to 70% of the windows width are sufficient;
  • The minimum distance from the wall to the radiator is 5 cm;
  • Between the windows and the battery leave 10 cm;
  • Between the floor and the heating device, it is possible to gap 10-15 cm, the most suitable value is 12 cm;
  • When the battery is installed not near the opening, but on a deaf wall, it is recommended to leave a 20 mm gap between the vertical surface and the radiator.

Calculation of the number of sections

If there is no possibility to establish the most effective heating devices, you can make an emphasis on the accuracy of calculations. At the same time, a sufficient number of sections determine. On 1 m³, 41 W thermal power will be required. When the windows are sealed, the value of this parameter decreases to 34 W. To determine the total area of ​​the room, you need to multiply its height on the floor area. To calculate the thermal power of the room, it is necessary to multiply its volume per unit of thermal power (34-41 W).

To determine a sufficient number of sections, you must first examine the documentation for the radiator. The manufacturer indicates the heat transfer of the 1st section. If you split the calculated value of the thermal power of the room on the heat transfer of 1 section, you can get a sufficient number of radiator sections.

How to choose heating radiators for a private house

View scheme layout

There are 2 options:

  • one-tube system;
  • two-pipe.

Communications that are summed up to heating devices are located in a vertical or horizontal plane. When installing a single-tube system, a closed circuit is formed. In addition, pipe wiring can be top or bottom. The two-pipe scheme has an indisputable advantage - the ability to adjust the temperature of the air in each room separately.

How to find out real heat transfer?

Information in the passport of the heating device is true only in the case when the difference between the average temperature of the coolant and the room corresponds to 70 ° C. Through simple calculations, it is necessary to find out the temperature of the coolant in the feed and reverse circuits, provided that the average temperature of the air temperature is taken as the basis of the room + 22 ° C.

In most cases, the obtained indicators in practice cannot be achieved due to limiting the capabilities of heating boilers. This means that the stated power value of 1 section in the instrument passport does not correspond to reality, and the error will be substantial.

How to choose heating radiators for a private house?

When choosing batteries for the arrangement of the autonomous system, the main characteristics are taken into account, the cost. In addition, pay attention to the degree of negative impact of the coolant to such devices.

Aluminum radiators are eaten by corrosion and burst from hydrowards.

Material refers to active metals, so it is rapidly destroyed by contact with impurities contained in water. The batteries do not withstand high pressure, so for apartments are not suitable, and in a private house are installed without fears. Due to low strength, such products will not stand regular exposure to hydrowards.

Batteries of steel do not always withstand a large pressure

For strength, such devices are inferior to bimetallic analogs, but exceed aluminum batteries. The average index of the pressure is 8 atm. Due to corrosion exposure, such devices serve less cast-iron batteries, but for this indicator they are better than aluminum analogues.

How to choose heating radiators for a private house

Pressure varies within 30-50 atm. The hydroudars for such radiators are not terrible. Such products are distinguished by a low weight, withstand temperatures up to + 130 ° C. The only lack of instruments is a high price, therefore, in private housing, they are rarely used.

Old good cast iron acquires the second life

The batteries of this group serve 50 years or more. Cast iron belongs to the group of passive metals, therefore it is not subject to destruction when contacting with impurities in water. Such radiators are held for a long time, during this period they continue to warm the air indoors.

The choice of heating devices for the water system always remains the prerogative of the homeowner, even when the installation is performed by the wage masters. But choose the batteries on the advice of sellers or the reviews of Internet users are not easy - the first often do not understand the topic and repeat the advertising slogans, the second "praise their swamp", which is quite explained. To find out which heating radiators are better to choose for an apartment or a private house, we offer to use a simple and understandable algorithm.

Instructions for the choice of batteries - a simplified approach

Before buying or ordering new heating radiators, it is necessary to explore the catalogs of large online stores. This will determine the order of prices and see the existing types of batteries. All water heating convection devices are divided into 4 groups:

  • aluminum sectional;
  • bimetallic - sectional and monolithic;
  • cast-iron;
  • Steel - panel and tubular.

Lyrical digression. You can read reviews and articles on resources that publish ratings of products of various brands. But the good use does not bring information - endless disputes are on the forums and fake feeds are written, and ratings are often compiled on top 10 manufacturers from the first search pages.

Beautiful heaters in the bedroom interior

To select the power of heating radiators, it is necessary to pre-calculate the amount of heat consumed on the heating of each room. Methods for calculating - in the area, volume or thermal loss of the building - published by a separate article. How to choose the batteries:

  1. Fuck the cost of a future purchase, let's follow more expensive and too cheap heater options.
  2. Select models that have liked in appearance, form and color, well fit into the home interior. Pay attention to the height of the batteries so that they are placed in the niche.
  3. If you live in the apartment of a high-rise home (9 floors or more), open the page with the technical characteristics of the selected radiators and find out the maximum working pressure of the water - the device must withstand at least 12 bar.
  4. For the hosts of private cottages, the pressure parameter is not of interest - models are suitable with any characteristics. If the house is heated with a wood or coal boiler, it is worth checking the maximum coolant temperature - the indicator above, the better.
  5. Ask, what connectivity methods are provided by manufacturers of selected batteries. The lower eyeliner allows you to better hide the heating highway, with a lateral version of the pipe you will have to be muted in the wall or leave in front.
  6. Find out the weight of the product and the installation method - outdoor or wall. Find out whether the radiator is equipped with installation brackets and huts, otherwise additional costs will occur. Radiator valves and crane Maevsky is usually purchased separately.

    To install instruments, you will need Futors, Maevsky's crane with a key and hanging brackets

  7. Make the final selection of the model and determine the size of the radiators by power. How the actual heat transfer is calculated 1 sections (panels), we will talk at the end of this instruction.

Please note - we did not mention the materials of the manufacture and types of instruments. In fact, this factor does not play a big role. Modern radiators differ little by technical parameters, it is important only the heat transfer indicator. The lower threshold of working pressure is only in high-rise buildings.

Next, we consider the device and characteristics of various batteries, compare their advantages and disadvantages. But first dispel the popular myths invented by advertisers.

Myths about heating radiators

In order to promote one or another products, three common non-residents were invented about the heating devices made from various materials:

  • Heatthilling of aluminum radiators is significantly higher than steel and cast-iron;
  • Radiators made of cast iron are massive, so it is warm and cooled for a long time, allegedly store heat;
  • In the central heating network, hydroudars and pressure occur, which only bimetallic heaters are withstanding.

Note. The main well-established myths are listed here, we will tell about the other in the process of describing radiators.

The composition of the silumin AK12

Compared to ferrous metals - steel and cast iron - aluminum carries out heat much better. I confirm the numbers: the coefficient of thermal conductivity λ aluminum products - 209 W / (M • ° C), steel - 47 W / (M • ° C), pig-iron - only 42 W / (M • ° C). In what snag: heating devices are manufactured not made of pure aluminum, but the alloy of the AK12 group - silumin, where 11-13% of silicon and other impurities listed above are present in the table.

The purpose of the additive of silicon is to increase the strength and corrosion resistance of the alloy. The physical properties of silumin others, thermal conductivity noticeably below - 168 W / (M • ° C). Given the thickness of the walls of the batteries of 4-5 mm, the difference in the heat transfer of aluminum and iron devices in practice is invisible. Put in the room 2 of such radiator the same power - you will not be able to determine which it works more efficiently.

The best heat conductor is copper. It makes lamellar plinth heaters and copper-aluminum water convectors.

Copper heating convectors

Stumbling stone - copper prices. The right photo shows the heat heater worth 70 y. e., Dimensions - 400 x 400 x 90 mm, thermal stream - only 430 W.

The following factors strongly affect the transfer of heat energy from any metal battery:

  • temperature and coolant temperature;
  • The surface area of ​​the device;
  • Delta temperature between air air and water in the pipes.

Reference. The difference between the average temperature of the coolant and the heated air is called the temperature pressure (DT). The value is subsequently useful when calculating the power of the instruments.

The remaining myths will dispel the items:

  1. When heating / cooling, the massiveness of the cast iron does not play roles, since its heat capacity is 9 times lower than being inside the water (0.54 kJ / kg • ° C against 4.18 kJ / kg • ° C). Therefore, the cast-iron battery will cool at the same time with the coolant, no longer. Silumin and steel are faster, since they can accommodate a much smaller volume of water.
  2. Hydraulic blows inside centralized heat supply networks simply does not happen. Maximum pressure in working mode - 10 bar, test - 12 bar. Modern aluminum devices calmly withstand such a pressure.

Construction and advantages of aluminum devices

The radiators of this type are manufactured by molding under pressure or extrusion. The finished product is a vertical single section or a whole unintellular battery (both varieties produces a well-known company Rifar). Of the individual sections, the heater of the required power is gaining, the method of compound is a threaded nipple with a gasket.

Inside the silicon radiator section, shown in the section in the photo, 2 horizontal collectors are pretended, between them - a vertical connecting channel of oval cross section. The outer heat exchange part is convection ribs covered with heat-resistant powder paint. The form of fins and the number of plates determines the manufacturer.

Reference. The height of the battery is considered to be between the centers of horizontal collectors. Aluminum products are offered in 3 standard versions - 35, 50 and 80 cm. The allowable pressure in radiators - 14 ... 16 bar, heat transfer sections with an inter-axis distance of 500 mm - about 190 W according to the Italian brand Global.

Device of the radiator section in the context

Advantages of aluminum alloy batteries:

  • low weight;
  • attractive appearance;
  • Effective heat transfer contributes to a large surface area;
  • Small capacity for water - 0.2 ... 1 l, depending on the size;
  • The relatively low price is 7 ... 10 y. e. For a section, Chinese models - from 5 y. e.

Low corrosion resistance is considered a lack of aluminum, although in practice heaters serve in central heating apartments for 20 years. Approval should be attributed to private homes, where too rigid water is used as a coolant, saturated with magnesium and calcium salts.

How to disassemble the battery sections
Methods of assembling sectional heater on threaded nipples with EPDM rubber pads

The second minus is inherent in any sectional batteries - when pouring the non-freezing coolant at the joints, leaks arise. One-piece modifications, for example, "Riffar Monolith", do not have such problems.

Pros and Cons Bimetal

How easy it is to guess the name, heating devices are made of 2 metals - silumin and steel. Externally batteries are indistinguishable from aluminum sections, but inside collectors and vertical channels iron tubes, welded with each other, are embedded. Steel frame is designed to solve 2 tasks:

  • protection of the synthetic part from the chemical effects of the coolant in old centralized systems;
  • Improving the reliability of the radiator by increasing the operating pressure threshold to 20 ... 30 atm.
How the bimetallic heating radiator is arranged

For reference. There are bimetallic models with double vertical channels made for the improvement of water duct and heat exchange. An example is a line of unsolved batteries Rifar Supremo shown below in the photo.

For the remaining technical characteristics, the bimetall differs little from aluminum - the power of 1 section, weight and capacity is almost the same. The operational advantages of radiators are also preserved, but a couple of flaws appear:

  • The price of the batteries is higher by 30-50%, for example, the original bimetallic section of the company Global Style Plus with an inter-axle interval of 500 mm costs about 15 y. e. (970 rubles);
  • Because of the different coefficients of thermal expansion of silumin and steel tube core can burst on welded joints, repair and close the leakage - unreal.
How is the monolithic unsolved heater
In the monolithic design, the collectors of adjacent sections are connected by welding. Feature of products "Riffar" - 2 vertical channels

An important addition. In the sale sometimes there are defective bimetallic radiators with steel tubes, sealed only inside collectors. The vertical section of the section remains unprotected.

Features of cast iron "accordion"

The device of batteries made by casting from gray cast iron, familiar to most homeowners. Like an aluminum "fellow", the heater is recruited from individual sections twisted by nipples through the gaskets (a long end key is needed).

The cast iron batteries present in the market are conventionally divided into 2 groups:

  1. Products of the Soviet MC-140 brand, the inter-axis interval standard - 300 and 500 mm.
  2. Designer models, cast in modern style, retro and so on. Distance between traffic jams - arbitrary.

The inexpensive "accordions" of the MS series is significantly losing with any radiators in appearance, are used mainly in industrial premises. The heat transfer section 50 cm is 160 W, the operating pressure is up to 9 bar, the contained volume of water is 1.45 liters. Cost - from 6 y. e. (420 rubles).

Comparison of cast iron batteries

Beautiful designer batteries from different brands are very different in dimensions, power and other parameters. The table shows the characteristics and prices of decorative heaters from Czech, Turkish and Russian brands (excluding the value of decorative shut-off valves).

Characteristics and prices of cast-iron radiators - table

Note. The numbers after the names of the products denote the mid-scene distance and the thickness of the heater in millimeters.

Cast-iron "accordions" are reliable in work, durable and completely not afraid of corrosion. In appearance, retroradiators confidently occupy the first position among all heating devices. Now reveal the negative points:

  • The transient price of design sections is noticeable on the table;
  • cast iron fragile, splits from shock loads;
  • solid product weight;
  • The battery accommodates 2-4 times more coolant than other types of radiators.

The so-called inertness of cast-iron sections is explained just an increased capacity. Two liters of water cools significantly longer than 0.2-0.6 l in the aluminum section. Especially severe modifications, for example, Retro Style Anerli, are produced in the outdoor version and are equipped with legs.

Advantages of steel radiators

Manufacturers offer 2 versions of iron batteries:

  • panel - flat and profile;
  • Vertical tubular (sectional).
Metal heater in context
Device standard panel (left) and vertical designer model (right)

Comment. Both species are produced in the design vertical version (see above in the photo). Known in the post-Soviet space brands: Kermi, Korado, Purmo, Arbonia and others.

Warning panels are welded from stamped steel plates with a thickness of 1.2 ... 1.5 mm. Side or bottom of the radiator are installed fittings for attachment. A convective ebony is fastened between the panels. Batteries are divided into types depending on the number of heating panels and profile finments, as shown in the table.

Classification of steel panel radiators

Operational indicators of panel heaters (taken according to the German radiator "Kermi" Type 22, installation size 100 x 50 cm):

  • permissible pressure - up to 10 bar;
  • Thermal capacity of 1550 W at water temperature at 75 ° C, the return - 65 ° C;
  • The volume of the coolant is 5.4 l;
  • The mass of units is 28 kg, the price is 95 y. e. (6300 rubles.).

The characteristics of tubular radiators are not too different from the panel. If you take the Arbonia 3050/22 two-row device, comparable to the size with the "Kermi" option (500 x 1014 mm), we obtain the power of 1481 W with the same working pressure and weight of 25.9 kg. Only the price of the product is another - 430 y. e.

Tubular batteries Arbonia
Tubular Radiators "Arbonia" in horizontal and vertical execution

As we consider the options affordable options, we list the pluses of panel batteries:

  • Steel panels are the most fiscal option among all radiators;
  • resistance to chemical corrosion;
  • acceptable design and appearance;
  • One-piece design allows you to pour antifreeze to the system and not be afraid of leaks;
  • The ability to pick up power without resizing - by adding heating panels and ribs (from 1 to type 10 to 3 pcs. Type 33).

The disadvantage of radiators is considered a low operational pressure threshold - 6 ... 10 bar. We will not refute this, but we will offer to watch the video of our expert, where the inexpensive steel panel is pumped up with the crimping pump to break the weld (pressure over 20 bar):

How to find out real heat transfer

Selecting the heating devices in the online store, it is difficult to find real parameters of the panel power or one section. Sellers are more profitable to declare the maximum heat transfer, which is practically unattainable when heating a country cottage or apartment. According to the passport, the water temperature in the supply pipe must reach 90 degrees, reverse - 70 ° C, room air - 20 ° C.

Reference. In modern household heat generators, the heating temperature is limited at 80 ... 85 degrees.

Selection sections on heat transfer We recommend doing this:

  1. Open the official site of the manufacturer of your favorite batteries and download instructions instructions. It is precisely indicated in it, with what the temperature pressure of the DT radiator gives the nominal amount of heat. Focus on 70/50 ° C mode.

    Heat Patterns of the kermi panels
    Power of steel kermi panels depending on the size and temperature mode - sample table

  2. If the instruction is missing, take the manufacturer data for the truth and multiply the heat transfer to the boost rate 1.5-1.8. Having made a one-hour stock, you definitely do not lose.
  3. The last paranolars of a single-tube system are chosen with a double reserve, as they get the smallest amount of thermal energy.

The most accurate method of selection is the calculation of heat transfer according to the specified temperature presumpture. The calculation algorithm is described in detail in the appropriate material.

Conclusions and recommendations

We hope the preceding description helped you to figure out which heating batteries are better for apartments for the price and technical indicators. Finally, we will give several practical advice:

  1. Use the instructions given at the beginning of this publication. Choose radiators that are more suitable for design and budget.
  2. The working pressure head of the coolant matters only for apartments of high-rise houses, the pressure of over 10 bar will withstand only bimetallic and aluminum batteries. For cottages and private cottages, any water heating devices are suitable.
  3. With a limited budget, boldly buy steel panels - they do not inferior to other heaters or convectors.
  4. Under the sampling system you need to take radiators with a large cross section of internal channels. Steel stamped heaters are better not to put, only tubular.
  5. By the price - quality and set of operating parameters, the first place occupies sectional batteries from lightweight aluminum alloy.
  6. Behind the bimetal is worth paying when there is no confidence in the parameters of the coolant - the pressure is unknown, rigid water is used.
  7. Try not to acquire frankly cheap radiators, blinded from an unknown material in the PRC. They will warm them, but for sure not long.

Conclusion regarding cast iron. The heating radiators of the old type MS-90 and MS-140 are cheap, but look non-zero. Beautifully designed models are incredibly road, and therefore inaccessible to ordinary homeowners. The cast iron becomes a rarity, and the outdated "accordions" of the MS series go into the past.

If the budget allows you to put design heaters, choose every battery in dimensions. In a narrow wall niche, it is better to place a vertical steel heating radiator, under the windows - stylish cast iron products. Heavy floor versions are desirable additionally to mount to the wall with a pair of brackets.

Features of heating in a private house

In country houses and cottages, the heating system usually connects to the boiler and has differences from centralized systems. The most important of them are:

  • The pressure of the coolant - it usually does not exceed 3 atm.;
  • Type and quality of the coolant.

Unlike centralized systems. in autonomous. With the proper operation of the boiler. Practically excluded the likelihood of hydroudar. This feature, as well as the low pressure of the coolant makes it possible to use almost any types of radiators, without fear of destruction and leaks.

If water is used as a coolant, its quality can also affect the operating conditions of radiators. In particular, rigid water with a large amount of salts can cause precipitation on the inner surface of radiators, and, as a result, to narrow the lumen and deterioration of heat transfer.

System type - open or closed - also important .

In an open system The oxygen dissolved in water is constantly present, which at elevated temperatures leads to quite active corrosion of some types of radiators. In closed systems With a membrane expansion tank, oxygen with initial heating of the coolant binds to insoluble compounds - metal oxides, after which corrosion stops to fill the fresh portion of water.

Also in private heating systems, antifreeze cannot be used, not freezing at minus temperatures. Their use allows you to stop the boiler in winter, which is convenient for country cottages and houses used for periodic accommodation. Not all types of radiators can be used in antifreeze systems.

The remaining myths will dispel the items:

  1. When heating / cooling, the massiveness of the cast iron does not play roles, since its heat capacity is 9 times lower than being inside the water (0.54 kJ / kg • ° C against 4.18 kJ / kg • ° C). Therefore, the cast-iron battery will cool at the same time with the coolant, no longer. Silumin and steel are faster, since they can accommodate a much smaller volume of water.
  2. Hydraulic blows inside centralized heat supply networks simply does not happen. Maximum pressure in working mode - 10 bar, test - 12 bar. Modern aluminum devices calmly withstand such a pressure.

Types of radiators and their features

Currently, the market presents a huge selection of models from various material and with different heat transfer. Before choosing heating radiators for a country or private home, you need to study their features and specifications.

The most common types of radiators:

  • cast-iron;
  • steel;
  • aluminum;
  • anodized;
  • bimetallic.

They are distinguished by the form, appearance, permissible pressure, heat transfer, as well as other characteristics, having studied which can be made optimal choice.

Cast iron radiators

Cast iron heating radiatorThis type of radiators was used in Russia in the king . In the houses that were built in Soviet times, they still rightly serve.

Cast iron batteries are heated for a long time, but for a long time and cool. The residual number of heat conservation is twice as much as the remaining types and is 30%.

This makes it possible to reduce gas costs for home heating.

Advantages of cast-iron radiators:

  • Very high resistance to corrosion;
  • Durability and reliability that are checked for years;
  • Low heat transfer;
  • Cast iron is not afraid of the effects of chemical reagents;
  • The radiator can be collected from a different number of sections.

Cast iron radiators have only one drawback - they are very hard.

The modern market offers cast iron radiators with decorative design.

What are good cast iron batteries

Cast iron is a classic material for tubular and sectional radiators. It is characterized by high thermal conductivity, withstands high temperature and water of any acidity.

Cast iron batteries are very heavy and sensitive to high pressure.

Aluminum

This type of batteries is primarily has a beautiful aesthetic appearance , correct and ergonomic shape, as well as excellent specifications. They are compact enough, can be sold with separate type sections. It is very convenient, since making the right calculations, you can choose the size that Optimally freeing your room . Aluminum radiators are available in different heights and can be placed at any comfortable corners of the rooms. Standard working pressure in which the heater is the most Effectively gives the heat , It is 6-12 atmospheres, the maximum allowed, with sharp jumps up to 25 atmospheres.

Aluminum radiators

Aluminum radiators

The advantages of such equipment include:

  • Excellent modern design;
  • The increased coefficient of heat transfer, depending on the thickness of the walls, can be up to 200 W per section of the standard size;
  • Low weight appliances, which simplifies their installation, even with their own hands;
  • By set of elements, you can select the required size that satisfies your requirements;
  • Beautiful powder coating that impede damage.

The main one minus such batteries According to consumer reviews, the possibility of long-term Operation only in closed cycle systems , with strict tracking over the level of the hardness of the coolant. Such networks must be made from the same material as radiators, as aluminum, when contacting brass and copper parts, can run Electrochemical reaction processes . Modern systems are recommended to be implemented by plastic pipes, and the heaters themselves are securely ground.

Important! Another phenomenon is inherent in aluminum batteries - it is Possible unpleasant sounds . They may appear subsequently the interaction of the metal with a liquid richly saturated with oxygen, resulting in hydrogen. Because of this feature, everyone is recommended. Radiator to equip Maevsky crane.

Taking into account all the above, we can say that Heaters made Aluminum , despite a number of positive properties, in urban apartments It is better not to mount.

What features of aluminum radiators

Sectional radiators are made from aluminum. Aluminum batteries are lightweight, quickly heated and well heated the room.

Aluminum is covered by corrosion when the acidity of water is increased and if there is contact with copper or brass pipes. Aluminum radiators are not recommended to use in homes with a pressure system of central heating more than 12 atmospheres, so they are more suitable for private houses.

Convector radiators

Convector radiators heating

Convector radiators

Convector type radiators are connected to a conventional heating system. A distinctive feature of a completely different way of functioning.

Panel, sectional or tubular radiators are heat in the environment from their hot surface, which allows you to heat the room.

The work of the convectors is arranged otherwise. Their design involves the presence of a plurality of thin air channels located between the plates ribs.

The air in the room passes through them, while heats up, it becomes easier and rises up, which provides continuous movement and mixing air, i.e. Standing heating. This allows you to evenly warm the room that it is important that the interference will not even have a multitude of interior and partition objects.

Correctly give preference to one or another type of radiators will help such a characteristic as power. It is easy to calculate it: in the room with a ceiling height of 300 cm and one window, for heating one square meter, you will need 100 watts. When there are two walls in the room, add another 20%. If there are two external walls and two windows, add 30%. When entering the window to the northern direction - 10% should be thrown. An important factor will be the installation of radiators, after all, whatever good you purchased batteries, if they are installed incorrectly, it is still zero. Preparation of radiators_topia

  • Convector radiators of different colorsThey are light, compact and reliable, because produced from copper, steel and aluminum - corrosion-resistant materials
  • Required a relatively small amount of water in the system.
  • Rather quickly heated and also quickly cool
  • Such radiators allow heating rooms with high ceilings
  • The heating system with convectable radiators allows savings when buying equipment. Those. In such a system, pipes of a small diameter are used, sufficiently low power of the circulation pump and the coolant itself has a small volume.
  • Very simple installation, which can be carried out without having special skills.
  • There is a huge selection of appearance options for the convector body. What can be a beautiful addition of your interior. Replace the body is very simple and takes it just a few minutes.
  • Increased safety, i.e. The heat exchanger is closed completely.

All batteries have their shortcomings that are functional. Convector radiator is durable, economical, safe and enough. The only minus is a high price, because they are made from high-quality and expensive materials.

Steel radiators

Steel radiators BenefitsSectional and panel radiators are the most optimal for a private house.

They are compact and characterized by good heat transfer, look quite modern in the interior. A distinctive feature is the ability to select various connection options depending on the type of radiator to the heating system of its own home.

In a private house with wide windows, the panel radiator will prevent the appearance of a draft and block the cold air flow.

Sectional steel radiators have an affordable cost, which is optimal for use in a private house.

Tubular heating radiator at homeTubular radiators for the cost are superior to panel and sectional . The technical characteristics of them are practically identical, differ in a more refined view. Tubular radiators are beautiful for use in the family with small children, because They have indisputable convenience in the drying of things.

The advantages of steel radiators is:

  • A good efficiency of the efficiency is combined with an affordable cost.
  • Low oxidation when using low water quality
  • Good service life
  • low weight and comfortable dimensions

Disadvantages:

  • High risk risk risk, which is able to destroy the battery for several years.
  • not very harmonious look
  • The need for washing every 3 years to avoid hosting the heating system of the house.
  • Restrictions in application when using a circulated liquid with an admixture of alkali reagents
  • Radiators are manufactured by finished panels, i.e. There is no possibility to choose the number of sections.

What you need to know about steel radiators

Steel is the main material for panel and tubular batteries. Such radiators warm and cost cheaply.

The steel radiator quickly rusts at contact with air, for example, when the water was merged, and the new one has not yet been filled.

Bimetallic radiators

The bimetallic radiator includes high resistance to corrosion of the best iron alloys and high aluminum heat transfer, as well as low weight.

The opposite side is the high price, the average class is not available. You can buy cheap models of bimetallic radiators, but from the qualities there remains only the name.

Bimetallic heating radiators at home

The opposite side is the high price, the average class is not available. You can buy cheap models of bimetallic radiators, but from the qualities there remains only the name.

Apply bimetallic radiators for a private house is not advisable due to high cost. They have the greatest strength, but the local network of the heating system does not have high pressure, therefore the advantage of this radiator in this case is useless.

By structure, radiators are divided into tubular, sectional, convectable and panel.

What are the advantages of bimetallic radiators

Bimetallic radiators are made of steel with aluminum and copper with aluminum.

The radiator made of steel and aluminum consists of a steel channel for circulation of water and aluminum outer plates. Steel is more resistant to rust, aluminum is quickly heated and removed heat into the room.

In the copper-aluminum radiator, the internal channels from copper warm up and give more heat than steel, even with a relatively low heating temperature.

The working pressure of the bimetallic radiator is up to 35 atmospheres, so they can be installed in apartments with a central heating system. Bimetallic radiators are lungs, so they are put in rooms with thin partitions.

Sectional

The battery consists of individual units, the number of which can be changed. This is a serious advantage of heating devices of this type. If the thermal calculation is incorrect and the radiator power is not enough, additional sections are added. If the house has been insulated and the need for powerful radiators disappeared, it is enough to remove unnecessary sections to reduce the energy consumption. The advantages of sectional models also include a stylish design that will fit into any interior. The disadvantage is considered a large number of joints, due to which the risk of depressurization of the battery increases.

Section radiator

Sectional heating radiator in the interior

What is a sectional radiator

The section radiator consists of several sections of 10 cm wide. You can order any number of sections. Sections have a cellular design in which the air circulates to heat the radiator faster.

Sectional radiators are bimetallic, steel, aluminum, copper and cast-iron. The thicker the section and the more their number, the higher the heat transfer of the radiator.

Sectional radiators are installed under the windowsill at a distance of at least 10 cm from it, 3 cm from the wall and 10 cm from the floor.

Tubular

They are distinguished by the original appearance, convenient for drying things. Reliable and durable due to the absence of joints - the radiator is a one-piece design. At the same time, it is important to choose the proper heating device by power, as it will not be possible to correct this parameter. tubular radiator

Steel tubular radiator

What is a tubular radiator

The tubular radiator consists of several curved pipes. They are made of metals resistant to corrosion. Radiators can be outdoor and wall, horizontal and vertical.

Such radiators stood in all old houses in our country. Today, the designs of this type are used as designer solutions. For example, pig-iron radiators with decorative forging are produced for retro interiors, and for premises with a large area of ​​glazing - light, unusual shapes painted in different colors.

Vacuum

Recently, the vacuum type of batteries has started to gain popularity. If you compare them with other types, they have a number of advantages. For example, they require a smaller amount of coolant, which will contact through the wall with a lithium-based specialist and boron having a boiling point of +35 degrees. Also, such radiators have excellent safety characteristics.

If you call other advantages, it should be noted:

  • Reducing the coolant level for 80 percent mechanism;
  • Reducing the use of coolant from the centralized heat supply mechanism tripled;
  • If induction boilers are used, you can save up to 40 percent of electrical energy;
  • carry out the installation of such batteries is quite simple even independently;
  • In radiators, absolutely no corrosion, as well as air traffic jams;
  • No need to use a powerful circulation pump unit due to low local resistance;
  • High thermal returns.

Quartz

Heating devices made of quartz - novelty in this segment. This type of batteries cannot be called high-tech, because it is an extremely simple option. Using the batteries of this type, it is possible to make an efficient, reliable and economical heating mechanism, which will maintain heat in winter. Quartz radiator will fit into any interior of the house.

Its design is simple and represents a monolithic slab, inside which the heating element is embedded, made of alloy chromium-leather alloy. The stove is made from a special system based on a quartz sand. The use of such sand is not accidental, because it can give a warmly warm, which has previously accumulated. Even if you turn off such a radiator from the heat network, it will long be warm, which will significantly reduce the consumption of electricity.

If we talk about the benefits of this type of batteries, then you should call:

  • Efficiency. The small consumption of electrical energy is the main advantage of heating devices from quartz, because other solutions consume a significantly more electrical energy and the rest of their advantages are simply going to no, because the price of electricity is quite large.
  • Substantial heat capacity. The quartz plate has quite serious thermal inertia. She heats up for a long time and slowly cools, as mentioned above.
  • Durability. The heating element in this case does not contact the environment, which does not allow it to oxidize and significantly increases the service life.
  • You can connect the thermostat, which allows you to obtain automatic control of the heating system.
  • Pretty low cost, if compared with electric type water heaters or other heating devices.

  • Fire safety. The temperature of this battery will not be more than 95 degrees, due to which the ignition of materials that are located next to the heater are completely excluded. This allows the installation of the device to be installed on almost any surface, including wood, plastic and plasterboard.
  • Electrical safety. Such a battery does not create serious electrical accessories and can work smoothly almost throughout the season.
  • Just installed. Quartz battery is attached to the wall using brackets.
  • Do not need maintenance and do not require serious care. The only thing to do with such a battery is to wipe dust from it.

What radiators are preferred for a private house

Having considered the described characteristics, you can draw conclusions which radiators are more practical and better for home heating.

  1. As a budget economy version, according to expert reviews, steel panel models are perfect. They have a different shape and size, they can be installed in a niche under the windowsill, where they will create a thermal veil of cold air, or at the bottom of the walls. They do not occupy a lot of space, resistant to the effects of any coolant, including antifreeze.
  2. More expensive option - steel tubular or cast iron batteries. Modern models are distinguished by an attractive design, do not require care and painting, easily clean. These types of rack batteries to the appearance of rust and salting precipitate. Their form allows not only to heat the house, but also dry things and shoes that for the cottage or village house is a pleasant option.
  3. Selection of wealthy people - bimetallic models with a long service life and increased heat transfer, resistance to corrosion and good operational qualities. Their installation for many years relieves the problem of heating, so the initial costs pay off over time.
  4. Aluminum precast radiators use in autonomous heating systems only with appropriate water treatment or the use of high-quality antifreeze.

What radiators to choose for a wooden house

Heating of a wooden house (we are primarily about cutters), indeed, has its own characteristics, since the thermal conductivity of the tree is low and depends on its breed. In addition, you must ensure maximum fire safety. But in general, the issue of providing heat, as well as safety rests primarily into the correct installation of the heating system, the choice of the boiler and the number of radiators. No restrictions on the type of radiators are not here: steel, cast iron, bimetallic, aluminum - they can all be used in a wooden litter.

By which basic criteria should choose radiators

It is important to pay special attention to this issue!

Type of heating system

Perhaps it is from this that it is necessary to repel first. In our country there are heating systems of two types: centralized and autonomous. And both of them require the use of different radiators.

1. Domestic centralized heating characterizes high working pressure, as well as its jumps. The fact is that we have, unlike Europe, a single-tube system in which radiators are connected in series. In addition, no one worries about the smooth inclusion of the centrifugal pump. And its sharp inclusion is fraught with hydroudar. And water in such a system does not shine neither purity or neutrality. It is rigid, its acidity is high, and in summer it is merged, which causes corrosion from many radiators. Therefore, for such a system, radiators are needed, which will withstand the working pressure in 6, and possibly in 9 atmospheres (they will say more in DEZ). Do not forget about the acidity of water, choosing radiators capable of working at high pH.

The best choice for the central heating system will be:

  • Cast iron radiators, characterized by durability and lack of inclination to corrosion. Working pressure - 6-16 bar.
  • Bimetallic radiators, also not subject to corrosion and withstand pressure up to 35 bar (sectional models) or up to 100 bar (monolithic models).

2. Autonomous heating is radically different from the central one. The water here moves in a circle (two-pipe system), its pressure does not exceed 3-5 bar, and acidity also complies with the standards. No in this water and extraneous impurities. Therefore, almost all types of radiators are suitable for autonomous heating.

For an autonomous heating system, experts recommend:

  • Aluminum radiators having the highest heat return.
  • Steel radiators have a low price that are distinguished by beautiful external design and original design.
  • In some cases, you can use old good cast iron radiators.

The use of bimetallic radiators in the system of autonomous heat supply is not entirely justified due to their high cost and less heat transfer compared to aluminum radiators.

Heat transfer of different types of radiators

Let us give specific digits by thermal conductivity (the value for one section is specified) Naturally, the average values ​​are indicated. More accurately, you can find out the characteristics in the passport of a particular radiator.

The heat transfer of the same section:

  • Cast iron radiators - from 100 to 160 watts.
  • Aluminum radiators - from 82 to 212 watts.
  • Bimetallic radiators - from 150 to 180 watts.

General heat transfer non-sectional radiators:

  • Steel radiators - from 1200 to 1600 watts.
  • Convectors - from 130 to 10,000 watts.

Summarize. The leader in heat transmission is aluminum. Steel ranks second. The third will give the cast iron, which also heats up for a very long time (that is, it has a large inertia). But he cools long, which sometimes comes to revenue.

What radiators are more reliable and durable

We again provide in the form of a list of uninterrupted work, which manufacturers guarantees.

  • Cast iron radiators - more than 50 years.
  • Aluminum radiators - from 15 to 20 years (provided that the pH of water is not higher than 7-8).
  • Steel radiators - up to 15-25 years
  • Bimetallic radiators - up to 20-25 years.
  • Convectors - 10-25 years.

So, if, pretending which radiator heating to choose, you put the main criterion for durability, it is not necessary to go far. Take the cast iron - no new-fashioned radiator will not last longer. Only manufacturers choose a verified, which makes really high-quality batteries using excellent raw materials and components for this. Behind him go bimetallic and steel radiators.

As for reliability, there are two aspects here - this is the ability to withstand pressure and how one or another type of radiators is demanding of the coolant. If we talk about pressure, then the undisputed leader will be bimetallic radiators, then aluminum, cast-iron and steel radiators are coming.

But to the heat carrier radiators are different. The most enduring in this regard are cast iron radiators, then go bimetallic. For steel radiators, it is important that the system does not pour water for a long period differently when the oxygen is inserted into the oxygen system, the appearance of corrosion. Well, the most "gentle" are aluminum radiators, which require pH within 7 - 8 units.

Appearance and finishing

1. Cast iron radiators - models of domestic producers, although they have become less than size, has undergone changes in design (their facade has become flat), but they cannot boast the finish. They are covered only by anti-corrosion primer, which involves subsequent staining. But the models of European manufacturers and the coating have a beautiful and durable, and the design is quite modern.

Separately, it is worth mentioning radiators in the style of "retro", they are expensive, but they are simply delicious.

Embodiment of cast-iron radiators in retro style.

2. Aluminum radiators are distinguished by a variety of design. Many manufacturers produce multicolored radiators that look very elegant and attractive. Models of aluminum radiators are distinguished by a wide range of inter-axes and sizes. This allows you to be perfectly fit into any corners of the house.

3. Steel panel type radiators can fit in almost any apartment interior. Smooth panels are not very striking, harmoniously merging with the situation.

And tubular steel radiators often favorably distinguishes unconventional form. For example, they may be angular or trapezium. And they protect the staircase steps, they fit into the niches and attic room. And everywhere such radiators look fresh and modern, brightly colorful paints.

4. Bimetallic radiators are very sophisticated for design. There are quite a few models that have not straight, but curved surfaces. This allows them to fit perfectly into placing with smooth angles. Such products produces, in particular, the RFAR plant. RS Bimetal Radiator from Sira can boast smooth and beautiful lines.

Model of bimetallic Rifar Flex radiators with rounded shape.

5. Sex convectors in terms of appearance differ only on decorative lattices.

Price categories

  • Cast iron radiators (except Retro models) - from 300 rubles per section.
  • Cast iron radiators "Retro" - from 2000 rubles per section.
  • Aluminum radiators - from 300 rubles per section.
  • Steel radiators (price for a whole radiator) - from 1500 to 10,000 rubles.
  • Bimetallic radiators - from 500-600 rubles per section.

The cheapest radiators are steel panel and cast-iron, especially domestic production. After them, aluminum injection radiators will go, extrusion models will be cheaper. But the most expensive will be bimetallic radiators, cast iron radiators in retro style and steel tubular models of radiators.

Centralized heating system: Main characteristics

For apartment radiators Special requirements are presented Since they will become part of the central heat supply, which has its own specifics of work. All such systems have similar operational conditions - the heat carrier for heating mains comes from the CHP or boiler room to a multi-storey house, where with the help of pumps and other equipment, is distributed through internal pipelines that deliver it directly into the dwelling.

Centralized heating

Centralized heating

The centralized heat supply system has its own underwater rocks and substantial disadvantages:

  1. Fluctuation of temperature indicators (then rapid warming up, then cooling);
  2. The possibility of sharp pressure drops - hydrowards;
  3. Low heat transfer coefficient to batteries, as a result, insufficient room heating and uneven temperature of the latter (one hot, other cooler);
  4. Seasonal drainage of the coolant from the system;
  5. Poor water quality - the presence of aggressive components, oxygen, sludge, rigidity, acidity, etc.

Heat distribution scheme in an apartment building

Heat distribution scheme in an apartment building

All of the above, over time, leads to increased equipment wear. And in a situation where a hydraulic blow occurs, compounds and themselves batteries can start proceed or burst , Bring a lot of trouble. Also because of the ideal coolant, which can, when circulating, carry a flare, rust particles, lime and other garbage, clogged channels and pipes of radiators. The result will be Lady of paid thermal resource , as well as increased corrosion reactions inside the heaters, which significantly reduces their shelf life.

Important! To minimize all the risks listed, you need to competently select the heating devices.

What threats are centralized heating

On the one hand, the supply of heat from outside is more convenient than autonomous heating - it is not necessary to mess with the installation of the boiler and its setting. Autumn will come, and the hot water is fun to run on your batteries, warming up the apartment.

But not everything is so smooth in the system of centralized heating:

  • In the water, which has undergone a long way, contains a lot of chemically active impurities that can cause corrosion of pipes and radiators.
  • And the small particles of the sludge, inevitably falling into the coolant, scratch the batteries from the inside, after a few years wiped them to holes.
  • And the water temperature is not always stable - then the batteries have a room temperature, otherwise it is impossible to touch them.
  • And the most important danger is a sudden huge pressure jump in the heating system, the so-called hydraulic panel. It happens, for example, for the reason that the locksmith closed the pump station too dramatically.

Previously, there were valves that have a smooth move, and with the appearance of ball cranes, it was possible to overlap water instantly. It can hydrate and then when the excess air in the pipe falls. The second leappatch of the prosecution is capable of doing a lot. Weak batteries do not withstand huge pressure and burst, splashing with boiling water, spoiling furnishings and cause damage to neighbors from below.

What parameters to choose radiators for an apartment

Now, knowing the weaknesses of central heating, you can already imagine what the requirements must meet good batteries. We list them.

1. The radiators declared by the manufacturer must exceed the pressure (both working and exceeding it one and a half times - test) in the heating system. For example, give the numbers. In five-storey houses of the old layout, this parameter is not more than 5 - 8 atmospheres. Multi-storey buildings of modern type are heated under pressure up to 12 - 15 atmospheres.

2. Separately, we note the possibility to resist the hydroward. Because, living in the apartment, from the jumps of pressure in heating to protect themselves difficult, it is better to prevent the trouble in advance. By the way - if you often hear the buzz and clicks in the batteries, contact the utility service. Pressure, see, "shakes" in the system.

3. The quality of water in the domestic heating system is unimportant, so the batteries must with honor to withstand its "chemical attack", not destroying. It is necessary to use radiators with a special coating from the inside or chemically neutral wall material. And the thickness of them is obliged to be such that the particles of sand and small pebbles do not rub it, acting like emery.

4. Reming what radiators are better for the apartment, we will not forget about the main function - to warm. That is, it is preferable to choose instruments from which heat returns more.

5. We will not wage and the design of radiators - few people will arrange scary cast-iron monsters of the wretched form, which in Soviet times were standing everywhere. I want the batteries to harmonically complemented the decoration of the rooms - today it is quite real.

6. The last parameter is the duration of the service. There is already comments excess. The less often you have to mess with the installation of these cumbersome and fairly expensive devices, the more profitable to the owners.

Radiators made of steel - Pali attacked by great pressure

Steel radiators distinguishes low weight and thickness. Good heat recovery and small water volume make them economical and efficient. Yes, they are inexpensive. But by pressure, they "pushed" - only 6-8 atmospheres withstand. They are not suitable for apartments, and the point.

Panel steel radiator.

Tubular steel radiator. They have a wide variety and differ in both the design and color.

Aluminum radiators - eaten corrosion, burst from hydrowarders

These radiators have a good appearance and have excellent heat transfer. However, wait, the inhabitants of the apartments - to rejoice is too early. Hot water with chemical impurities and great acidity quickly "bissing" aluminum radiators from the inside. After all, aluminum is too active metal. And he does not cope with greater pressure. Average operating pressure indicators - up to 16 atmospheres. And the hydrolyon is able to destroy even a very new aluminum radiator.

Aluminum radiators have a very attractive appearance and can give heat as simply heat heat and convection, but absolutely not suitable for the apartment.

Bimetallic radiators - all are good, only roads

This is one of the newest developments of heating devices. Such radiators are called bimetallic - after all, there are two metal in them. It can be, in particular, aluminum and steel, or aluminum and copper. An aluminum alloy made ribbed curly housing, and inside the core of steel or copper.

The device of the bimetallic heating radiator.

Manufacturers ensure that such batteries will work at least forty years. For the apartment they are suitable for all indicators, what you can make sure.

  • The temperature they withstand even up to 130 degrees.
  • The operating pressure of them is declared to 30 - 50 atmospheres, depending on the manufacturer and model. With them you can stop afraid of the hydrowards.
  • Anti-corrosion outer and inner primer makes batteries durable and resistant to destruction.
  • Light weight makes installation, carrying and transporting similar batteries. Hourly.
  • The appearance of them pleasantly caresses the eyes - beautiful white or colored panels are much aesthetically familiar with cast iron "accordion".

Alas - the cost of these radiators is quite high. And if you offer something like this in a democratic price - do not believe. The fake will be trapped. If you buy, then products of proven brand - Russian company Rifar, Italian - Sira or Global. There are Chinese good manufacturers. They, like Russian, the price is somewhat lower than that of radiators come from Europe.

Good old cast iron - finds the second life

Years fifty, no less, died out to live such a radiator. In vain, some manufacturers of new products argue that it is time to forget about this "old". Long thinking which heating radiators to choose for an apartment, many stop on cast-iron batteries. They do not "throw focus" when contact with dirty domestic water in the heating system. Chemically passive this metal, and it is not afraid of a high acidity or the presence of chemical additives in the coolant. And the thick walls will not hurt any abrasive. So the cast iron for the apartment (especially in the old house) is very good.

Cast iron heating radiator MS-140.

  • Cast iron radiators are distinguished by the fact that they hold heat for a very long time - the residual number of its saving is 30 percent. And all other types of batteries are twice as smaller than
  • The impact of heat due to the radiation method of heating is much more efficient than when using convection (both in bimetallic and aluminum products. Cast iron radiators warm not only air, but also close items.
  • When draining water from the system during the summer, cast iron radiators are not exposed to strong corrosion - it is a significant plus.
  • The large area of ​​heat transfer is another plus.
  • Pressure drops, which sinters central heating, cast iron usually transfers well. Until nine - twelve atmospheres can reach working pressure. But it does not always withstand high power hydroudars - brings the fragility of this metal.
  • The cost of these devices is usually lower than bimetallic radiators. Sometimes it is a defining factor.

These radiators are heavy, of course, that delivers some inconvenience when installing them. Well, yes, the cast iron a priori can not be easy. But this weight turns into a large wall thickness, gives radiators the necessary strength. Putting cast-iron radiators once (and this will deal with these specially trained people - plumbing), you can forget about their replace for many years.

The appearance of cast-iron radiators today is no longer so poor, as in the time of the USSR. There were very attractive externally batteries of figure casting, performed in the style of "retro", which are very well harmonized with exquisite rooms. For example, you can mention Roca and Konner products.

True, the cost of such miracle batteries is quite high. More budget is Ukrainian, Russian and Belarusian models, many of which should be painted before use. But they look quite adequate, their design fits into the interiors of modern apartments.

Calculation of the number of sections or total power of radiators

Without prior calculations, it is better to do not start!

Calculation on basic formulas

As mentioned above, the calculation of the amount of radiators to a separate room can be produced in two ways - on the area or by the volume of the room.

It is believed that to compensate for the heat loss of the building and to create a comfortable temperature for a person, it is necessary to provide 1 m² of thermal power to 100 W.

The calculation is thus produced by the formula:

N = S × 100 / PC,

where characters have the following values:

N- the number of radiator sections;

S- room area in m²;

PC - Thermal power of one section of the radiator - this magnitude can be found in the passport of the product.

A more accurate calculation can be carried out by calculating the volume of the heated room, since in this case the height of the ceilings of the room is taken into account. The calculation by volume implies 41 W power with a heating system by 1 m³ for a panel house, or 34 W - for brick. The formula acquires the following form:

N = S × H × 41 (34) / P c

The designations in the formula are the same, with the only addition that h - This is the height of the ceiling.

Of course, if it is planned to purchase a non-separable radiator, which is a one-piece design, then carry out division into the specific power of the section PC - No need, that is, this part is simulated from the formula. The resulting value will show how the total radiator power is necessary for this room.

However, these formulas will be valid only for standard average conditions. Therefore, the calculation of the radiator in the area or the volume of the room is important to take into account the correction coefficients, which are determined by the minimum winter temperature in the region of living, the features of the location of the room, the quality of the insulation of walls, the number and type of windows, the availability of the door to the street or on the balcony. Moreover, even the location of the batteries and the diagram of their inserts in the heating circuit can be considerable to calculate thermal power.

List all correction coefficients and bring a sufficiently bulky formula of calculation in this article, probably no point. It is better to offer the reader to take advantage of a convenient calculator, in which the basic dependencies are already laid.

Calculator calculating the necessary thermal power of heating radiators

To calculate, it will be enough to specify the requested data. The calculator will determine the number of sections of the selected type of radiator. If the calculation is performed only to determine the total thermal power required for high-quality room warming (for example, to select non-separable models of steel or aluminum batteries), the field with the requested specific passport power of one section is left blank.

So, choosing new radiators for the apartment, it is not necessary to over-save, since cheap products are quite capable of seriously complicating life not only to owners of housing, but also the neighbors living below. In the event of an emergency situation with poor-quality radiators, it is likely that you will have to lay out a round sum not only for new batteries, but also to buy an outdoor coating, as well as to repair the lower apartment.

Therefore, to the question of choice, it is necessary to approach with maximum intelligence, collect information about the operational parameters of the central heating system operating in the house, as well as carefully examine the technical documentation of the acquired radiator. Only by completing these recommendations, you can provide an apartment with reliable and high-quality batteries that will not be submitted in any conditions and will ensure effective room heating.

And at the end of the publication - a very voluminous and informative video lecture on the features of various types of radiators and the rules of their choice. You can learn the induction boiler by reference.

How to find out real heat transfer

Selecting the heating devices in the online store, it is difficult to find real parameters of the panel power or one section. Sellers are more profitable to declare the maximum heat transfer, which is practically unattainable when heating a country cottage or apartment. According to the passport, the water temperature in the supply pipe must reach 90 degrees, reverse - 70 ° C, room air - 20 ° C.

Reference. In modern household heat generators, the heating temperature is limited at 80 ... 85 degrees.

Selection sections on heat transfer We recommend doing this:

  1. Open the official site of the manufacturer of your favorite batteries and download instructions instructions. It is precisely indicated in it, with what the temperature pressure of the DT radiator gives the nominal amount of heat. Focus on 70/50 ° C mode. Heat Patterns of the kermi panels

    Power of steel kermi panels depending on the size and temperature mode - sample table

  2. If the instruction is missing, take the manufacturer data for the truth and multiply the heat transfer to the boost rate 1.5-1.8. Having made a one-hour stock, you definitely do not lose.
  3. The last paranolars of a single-tube system are chosen with a double reserve, as they get the smallest amount of thermal energy.

The most accurate method of selection is the calculation of heat transfer according to the specified temperature presumpture. The calculation algorithm is described in detail in the appropriate material.

Prices for radiators

The cost of heating devices varies significantly depending on the following factors:

  • brand and countries of origin;
  • material and production technology;
  • Design.

Italian, German, Finnish, Czech batteries are more expensive than Russian, but according to their technical and operational characteristics, the product of the domestic producer is little inferior and even exceeds many foreign counterparts.

Buying heating radiators for a private house - the article is quite expensive. But if you make the right calculations and pick up the cost-effective devices, then the costs can be significantly reduced.

The average cost of aluminum radiators for the section is within 1227-8200 r., Bimetallic devices - 3000-11900 p. The cheapest of them can be purchased at a price of 1100 p. The range of rates for steel radiators is also quite wide: from 830 to 60 000 r. Models made of steel cost from 3500 to 26,000 p. Cheap cast iron batteries can be purchased for 500-1000 rubles. In demand uses cast iron devices for 3000-8000 p.

Retro style batteries can be found from 8000 p.

If the batteries are needed for an integer home, even inexpensive devices are poured into a penny. In addition, expenses are added to the accompanying goods: valves, thermostat heads, brackets and other parts.

Conclusions and recommendations

We hope the preceding description helped you to figure out which heating batteries are better for apartments for the price and technical indicators. Finally, we will give several practical advice:

  1. Use the instructions given at the beginning of this publication. Choose radiators that are more suitable for design and budget.
  2. The working pressure head of the coolant matters only for apartments of high-rise houses, the pressure of over 10 bar will withstand only bimetallic and aluminum batteries. For cottages and private cottages, any water heating devices are suitable.
  3. With a limited budget, boldly buy steel panels - they do not inferior to other heaters or convectors.
  4. Under the sampling system you need to take radiators with a large cross section of internal channels. Steel stamped heaters are better not to put, only tubular.
  5. By the price - quality and set of operating parameters, the first place occupies sectional batteries from lightweight aluminum alloy.
  6. Behind the bimetal is worth paying when there is no confidence in the parameters of the coolant - the pressure is unknown, rigid water is used.
  7. Try not to acquire frankly cheap radiators, blinded from an unknown material in the PRC. They will warm them, but for sure not long.

Comparison of battery packs from various materials

Characteristics of the heaters of the same size made from various materials - comparative table

Conclusion regarding cast iron. The heating radiators of the old type MS-90 and MS-140 are cheap, but look non-zero. Beautifully designed models are incredibly road, and therefore inaccessible to ordinary homeowners. The cast iron becomes a rarity, and the outdated "accordions" of the MS series go into the past.

If the budget allows you to put design heaters, choose every battery in dimensions. In a narrow wall niche, it is better to place a vertical steel heating radiator, under the windows - stylish cast iron products. Heavy floor versions are desirable additionally to mount to the wall with a pair of brackets.

Heating Radiators: Select the appropriate option for a private house, installation technology

Heating Radiators: Select the appropriate option for a private house, installation technology

The radiator is the necessary link of the heating mechanism of a private dwelling or apartment. He is responsible for the room to be comfortable and warm. Therefore, when it is elected, it is necessary to take into account not only the cost and external execution, but also the specifications of a particular product. After all, if the characteristics declared the creator of the radiator will not be the same in fact, then the rapid wear of the device and its breakdown is simply inevitable.

Main characteristics

In a private house, in contrast to high-rise buildings, an autonomous heating mechanism is installed, that is, a system that does not depend on the conventional boiler room in any way. For this reason, the temperature of the coolant, as well as the network pressure will be completely different.

When you choose the heating batteries that will be installed in a private house, a number of factors should be taken into account:

  • In the buildings of this type, the pressure on the coolant, tanks and radiator pipes will be significantly smaller. In fact, the radiator batteries will not experience such loads, due to which any models can be selected, even with thin walls.
  • In the construction of the type of pipes under consideration, the length of the pipes from the heat source to the radiator is small, if compared with multi-storey buildings. For this reason, thermal losses are practically zero, and the heat carrier will be stronger. That is, in a private house, you should install models that will withstand such temperatures.
  • It is necessary to quite a little liquid to fill such a heating system. If you wish, you can add ethyl alcohol and antifreeze. So you can make protection for radiators and pipes if the boiler will not be turned on for a long time.
  • Even the slightest possibility of the occurrence of so-called hydrowards is excluded. True, a problem, expressed in the freezing of water in the pipes, may appear in the houses of a private type. It will be the reason that the batteries can simply burst if a person before leaving forgot to drain the water from there.

In the choice of heating radiators for a private house, it should be repeated from the main parameter - the area you are going to sculpt. In the same cottages, the space requiring warmth will be greater, energy consumption will be the same. It is best to install such batteries that will allow high-quality warming at a minimum of thermal costs.

Views

It should be said that the heating batteries are of different species. And here it is not so much about their form and sizes, how much about the material from which they are made. After all, it is no secret that various metals have different heat transfer indicators, due to which the efficiency of the batteries can vary significantly.

If we say specifically about the types, then there are radiators:

  • from cast iron;
  • from aluminum;
  • bimetallic;
  • vacuum;
  • of steel;
  • quartz.

Now let's say about each type in more detail.

Cast iron

The models under consideration are installed in our homes over a hundred years. Today they are very in demand due to ensuring high-quality room heating. They were also among the most popular in the USSR.

If we talk about their advantages, then you should call:

  • long operational period;
  • Excellent thermal returns;
  • High strength, as the batteries can easily withstand high pressure inside and easily transfer the mechanical impact;
  • They work even with the poor quality of the coolant;
  • have resistance to corrosion formation.

At the same time, cast iron models have a number of minuses:

  • large sizes, which significantly complicates transportation, maintenance and installation;
  • a small thermal conductivity due to the massiveness of the metal and the fact that its surface of the porridge;
  • Batteries need systematic and constant care - painting and maintenance;
  • The walls should be good attachments for their installation;
  • occupy a large area.

In addition, cast-iron models are not too attractive appearance, which almost always distinguishes them from the interior not the best. Therefore, it is often necessary to put additional jewelry on such radiators.

Steel

If we talk about this type of radiators, they are divided into three categories:

  • panel;
  • from sections;
  • from pipes.

Steel panel batteries are also called convectors, because heat supply is carried out using the convection process. They usually form a rectangle form, which forms two welded panels. The coolant moves between them on special channels. A similar radiator has a small weight, small sizes, which makes it possible to heat up in a short time and maintain a good temperature.

If we talk about disadvantages, then the main problem is a bad resistance of mechanical damage and not too good pressure indicators. In addition, such models are very susceptible to corrosion.

According to the characteristics, steel batteries from sections are something similar to cast-iron, although it has a number of serious differences:

  • Pressure inside here is at the level of 16 atmospheres;
  • Due to the presence of welded connections, radiators have increased strength;
  • Large operational period - up to 50 years.

This type of radiators is not very common, because their significant disadvantage is the high cost. Tubular steel batteries in their functionality are similar to sectional and panel radiators, but their price will be even higher. The main reason for this is that they have a rather pleasant appearance, which allows you to find a model under the interior. Yes, and on such batteries, it is extremely convenient to dry things that will be important for families where there are small children.

Aluminum

Aluminum refers to the category of metals, which are perfectly carried out. For this reason, such radiators can provide full-fledged heating of almost any room.

Their benefits are:

  • Excellent characteristics of thermal returns;
  • small dimensions;
  • Good working type pressure, which fluctuates in the borders of 12-18 atmospheres;
  • Small mass.

The coolant in the radiators of this type circulates very well, which allows to provide excellent heat transfer. Such circulation here is possible due to the presence of free tubes of the intercoletory type. In the market, such models are pretty wide.

The cost of aluminum batteries will depend on the manufacturer But in general, it is quite accessible due to the low price of aluminum itself. In addition, such models have an attractive appearance, which makes it possible to consider them not only as a heating device, but also as part of the interior of the room. Thanks to its strict and neat geometric forms, such a battery can easily fit into any interior.

But aluminum models have their own minuses:

  • they are extremely sensitive to the quality of the coolant, due to which the installation of water filtering is required;
  • Very susceptible to serious pressure drops, so it is necessary to constantly control its level;
  • It is quite bad to oppose the formation of corrosion, even despite the presence of a protective coating on a polymer basis;
  • have a small service life - no more than 15 years.

In addition, the positive return of such batteries is not always an advantage. Good work of such a battery drives warm air up, which accumulates at the ceiling, which can cause a sharp drop temperature. Therefore, before buying such batteries, the amount of heat required for the room should be calculated.

Aluminum batteries are divided into three categories that will differ from each other by device and opportunities:

  • Sectionable condated. Their device makes it possible to replace the plates that have broken.
  • Whole. Have a solid design and differ plasticity.
  • Combined. They combine all the best of the two categories mentioned above. They are considered one of the best solutions for owners of their own homes. If you fully comply with the operating conditions, then such radiators will be able to stop 10-15 years and will really effectively warm the house when it's cold on the street.

Bimetallic

As a rule, the inner part of such radiators is made of steel or copper, which makes it possible to ensure their good work and enhances safety. And the outer side is usually equipped with aluminum ribs. To date, bimetallic batteries are considered the best solution in this area. According to manufacturers, their batteries will be able to serve about 40 years. At the same time, they have a greater value, but still their characteristics provided them with excellent positions on the market. It is advisable to buy similar solutions in case the price of the price is not the main one. But they will definitely pay off the money and will work quite a long time.

Vacuum

Recently, the vacuum type of batteries has started to gain popularity. If you compare them with other types, they have a number of advantages. For example, they require a smaller amount of coolant, which will contact through the wall with a lithium-based specialist and boron having a boiling point of +35 degrees. Also, such radiators have excellent safety characteristics.

If you call other advantages, it should be noted:

  • Reducing the coolant level for 80 percent mechanism;
  • Reducing the use of coolant from the centralized heat supply mechanism tripled;
  • If induction boilers are used, you can save up to 40 percent of electrical energy;
  • carry out the installation of such batteries is quite simple even independently;
  • In radiators, absolutely no corrosion, as well as air traffic jams;
  • No need to use a powerful circulation pump unit due to low local resistance;
  • High thermal returns.

Quartz

Heating devices made of quartz - novelty in this segment. This type of batteries cannot be called high-tech, because it is an extremely simple option. Using the batteries of this type, it is possible to make an efficient, reliable and economical heating mechanism, which will maintain heat in winter. Quartz radiator will fit into any interior of the house.

Its design is simple and represents a monolithic slab, inside which the heating element is embedded, made of alloy chromium-leather alloy. The stove is made from a special system based on a quartz sand. The use of such sand is not accidental, because it can give a warmly warm, which has previously accumulated. Even if you turn off such a radiator from the heat network, it will long be warm, which will significantly reduce the consumption of electricity.

If we talk about the benefits of this type of batteries, then you should call:

  • Efficiency. The small consumption of electrical energy is the main advantage of heating devices from quartz, because other solutions consume a significantly more electrical energy and the rest of their advantages are simply going to no, because the price of electricity is quite large.
  • Substantial heat capacity. The quartz plate has quite serious thermal inertia. She heats up for a long time and slowly cools, as mentioned above.
  • Durability. The heating element in this case does not contact the environment, which does not allow it to oxidize and significantly increases the service life.
  • You can connect the thermostat, which allows you to obtain automatic control of the heating system.
  • Pretty low cost, if compared with electric type water heaters or other heating devices.
  • Fire safety. The temperature of this battery will not be more than 95 degrees, due to which the ignition of materials that are located next to the heater are completely excluded. This allows the installation of the device to be installed on almost any surface, including wood, plastic and plasterboard.
  • Electrical safety. Such a battery does not create serious electrical accessories and can work smoothly almost throughout the season.
  • Just installed. Quartz battery is attached to the wall using brackets.
  • Do not need maintenance and do not require serious care. The only thing to do with such a battery is to wipe dust from it.

Popular manufacturers and reviews

In the segment of cast-iron models, the most famous manufacturers are Chinese Tokio and Konner companies. A good domestic model of such batteries will be MS-140.

If we talk about steel panel solutions, the products of Korado, Buderus and "Liday" are considered the highest quality. But tubular steel solutions are usually issued by foreign companies. Among them, Zehnder, Arbonia and Delonghi are allocated.

Aluminum batteries are issued both foreign and domestic companies. Among them are such well-known manufacturers like Global, Ferroli and Riffar.

Bimetallic models are produced by both foreign and domestic firms. If we talk about domestic, then the brand "heat transfer," and if there are products of the brands of Polywarm, Sira, Royal Thermo Vittoria and the German company Kermi. When choosing ceramic batteries, it is worth paying attention to the products of the brand "Teplako".

Now let's talk about the experience of using various types of batteries by users and their reviews. It is logical, because manufacturers often declare one, and in practice we get completely different. If we talk about cast iron radiators, then users note that even beautiful solutions are not easy to install and they have a rather serious mass. In addition, it is often necessary to install additional brackets.

We will say a few aluminum radiators in more detail by reading the reviews of user batteries of various brands. If we talk about Sira aluminum batteries, then users note that they warmly warm and have an excellent appearance. Users also celebrate good heat transfer models. But many are not very satisfied with a considerable value of solutions from this company. Also, users are praising such batteries from Global and note that they warmly warm in combination with the boiler and have an excellent appearance. The same applies to solutions from Rifar.

Bimetallic batteries users also do not bypassed attention and in general respond about them very flattering. For example, Rifar batteries look great in different interiors, quite durable and can withstand large pressure, as well as high heat carrier temperature. In general, it is impossible to make some clear rating of radiators, because they all have a number of their positive and negative parties. You can clearly note one thing - in any case, it should be individually determined which batteries in a particular private building will be the best solution.

What better to choose?

If there is a desire to choose an economical option for a country wooden private structure, it is best to install high-quality aluminum radiators. Such solutions have everything you need: modern design, ease, affordable price, and their negative sides are not so serious in the conditions of the autonomous heating mechanism of the private house.

If money is not such a serious question, then it will be an excellent solution to the installation of cross-type bimetallic batteries, especially if we are talking about a copper-aluminum combination. And if there are small children in the house, then to protect them and other households, you can stop your choice on convection options, completed with certain protection options. If you need to hide radiators, then you can use outdoor convection solutions.

If the house has a stove with water contour, the easiest fuel boiler or your home is equipped with gas heating, you can use cast-iron batteries tested by time. Despite the fact that their choice entails difficulties with the installation and mass, they at the same time allow you to significantly smooth out temperature fluctuations and to store heat for a longer. Yes, and now you can easily choose options with a pleasant design, if they are on your pocket.

Installation rules

Heating of radiator type in his own home - the key to comfort and coziness in the fall and winter. Well, when such a mechanism has already been connected to the heating mechanism of centralized type. If there is no such thing, there is a need to apply an autonomous heating. If we are talking about making the installation of the heating system with your own hands correctly, it should be said that the most important element will be the choice of options for connecting radiators in the house of your own construction.

A number of people and are not suspected that it plays a very significant role in the heat transfer device, circulation inside the heat carrier and the speed of hot water movement. The above as a whole will have a significant impact on the efficiency of the entire mechanism.

The first thing you need to figure it out, this is a pipe layout. This can be called an important point, because the tenants of their own houses at the stage of their construction rarely when they can clearly and correctly calculate the costs that will be made on the formation of the heating system, because it is necessary to make savings on various kinds of materials. Typically, the method of connecting pipes can be either one or two-pipe. The first option is economical, in which a pipe is carried out from the heating boiler on the floor, which comes through all the walls and rooms and which returns to the boiler. Radiators should be installed on top of it, and the connection will be carried out using nozzles from the bottom. At the same time, hot water goes in the pipes, completely filling the batteries. Then the water is lowered and through another nozzle enters the pipe. In fact, there is a serial connection of the radiators due to the lower connection. But there is a minus, because at the end of such a connection in all subsequent radiators the temperature of the thermal carrier will be lower.

You can solve this moment in two ways:

  • Connect to the entire mechanism a special circulation pump, allowing uniformly in all heating devices to distribute hot water;
  • Connect additional batteries in the latest rooms, which will increase the heat transfer area to the maximum.

If we talk about a two-pipe layout, then for your own house, a similar connection system will be more efficient. But at the same time, expenses will be significant due to the fact that it is necessary to carry out the divorce of two pipes. One must be put to supply hot water, and the second to connect to its removal.

When it all became clear with this question, it should be focused on the joining the heating batteries. The most common side will be. To make it, you should display pipes on the side of the wall and connect to two batteries - on top and bottom. From above, a pipe feeding the heat carrier is usually connected, and from the bottom - output. Effective will also connect a diagonal type. To perform it, it follows to start to the pipe at the top to connect the pipe feeding the heat carrier, and to the bottom located on the other side - the return. It turns out that the thermal carrier will be transported diagonally inside the radiator. The effectiveness of such a mechanism will depend on how the fluid is distributed in the radiator. Rarely when several battery sections can be cold. This happens only in cases where the ability of the skipping or the head is weak.

Note that the connection of the radiator from below can be not only in one-tube, but also two-pipe versions. But such a system is considered extremely ineffective. In this case, it will still be necessary to establish the circulation pump, which will significantly increase the cost of creating a heating mechanism and will create electricity costs that are needed for the pump operation. If we talk about what you do not need to do, then this is not to replace the flow of water in the return. As a rule, the presence of this problem shows debugging.

When installing decorative screens, the visibility of the thermostat is overlap, which is not necessary. Batteries will be basked for a long time. At the same time, it is impossible to mount the head of the thermostat in a vertical position, because it will lead to its unstable work.

Installation of heating radiators with their own hands in its own house is associated with a number of moments who do not say that this is an easy process. His complexity consists also in the fact that in each individual case it is necessary to selection batteries for one or another structure, as well as to know how in a private house, which is already built, pass pipes. Also an equally important fact will be an understanding of the needs for heating and carrying out all necessary calculations.

In addition, we should not forget that there are various connection schemes and something that may be inefficient in one house, in another will be an excellent solution. If you have decided to make the installation of heating radiators yourself, then it is necessary to thoroughly examine theoretical moments, as well as if possible, at least consult with a specialist who will prompt that during the installation of radiators and the heating system as a whole should be paid particularly close attention.

On how to choose the right heating radiator, see the next video.

Competent planning, calculations and the choice of optimal equipment for building a home heating system is of paramount importance for the effectiveness of its further operation, and for your wallet. One of the main nodes of the heating system directly are heating radiators. Just about choosing these home network devices and will be discussed in this material.

What you need to consider when choosing a radiator for a private house

One of the advantages of a private house is an autonomous heating system, which is calculated and mounted by the individual wishes of the host. To the question of which radiators are better for a private house. Answer is easier than when choosing radiators for an apartment connected to the central heating network of the microdistrict.

Unlike the central heating system of urban apartments, a closed system of a private house has the following positive characteristics:

  • Works at low pressure and is the possibility of creating a favorable environment;
  • There are no such huge hydrowards here, due to this range of the choice of radiators offered by the market, significantly expands;
  • In compliance with the technical conditions of the acidic balance of water, the list of radiators selection is quite extensive.

Given the above mentioned positive characteristics of the autonomous home heating system, the main emphasis in the choice of radiators should be done on the maximum heat transfer ratio and good price-quality ratio. By and large for operation in a closed home heating system, any radiators, steel, aluminum, bimetallic and even cast-iron can be used. But some points still need to consider what you read further.

Below will look at all possible types of heating radiators for a private house, and we define the best options.

Tubular and panel steel radiators

one. Panel steel radiators - The most budget devices. At the same time, they have good characteristics of heat transfer, compact enough and fit well into the interior. Depending on the type of execution, there is a choice of various connection options, to the heating system of the house. In private houses with wide window openings, the panel radiator overlaps the cold air flow and prevents the appearance of drafts.

Panel steel heating radiatorsPanel steel heating radiators.

For those who are looking for good heating radiators with an affordable cost - this is a fairly optimal option for use in your home.

2.  Tubular steel radiators - According to the price bar, they stand above panel, and according to technical characteristics, they are approximately equal, the mark-up is mainly due to a more refined species with claims on design elements. Also, tubular radiators are convenient to use for drying things, which is important in families with a lot of children.

Tubular steel radiators design options:

When choosing a steel radiator for a private house, we obtain the following advantages:

  • Available cost in combination with a good efficiency of the efficiency
  • Low oxidation from poor-quality water
  • Long service life
  • Convenient dimensions and light weight

The following can be attributed to the following:

  • Not too harmonious design, which primarily shows that it is still a heating system, and not the decor element.
  • Also, despite the guarantees of manufacturers, steel radiators are desirable to rinse once every 3 years to prevent the process of holding the heating system at home.
  • Another disadvantage of steel batteries is the need for constant filling, otherwise a rust appears that can kill the radiator over several years.

Aluminum radiators

The aluminum radiator was widely used for the heating systems of the private house. Such popularity is explained by the modern design and high thermal power. The price range of aluminum radiators is extensive, it all depends on the manufacturer. The cheapest is the radiators of Russian manufacturers, judging by the reviews of users, it is better to take overseas analogues that cost a little more expensive.

If you choose an aluminum radiator for the local heating network of a private house, then you need to observe a number of sufficiently important conditions for the choice and operation that are provided below:

  • The aluminum radiator is very sensitive to the parameters of the circulating fluid. It is important to observe the necessary level of water acidity, otherwise aluminum can be collapsed over several years.
  • High thermal power of aluminum radiators has the opposite direction. The warm air flow is too quickly rising at the top and often the temperature difference occurs between the ceiling and floor. Therefore, when choosing aluminum radiators, it is necessary to make an accurate calculation on the area of ​​the room, otherwise the floor can be cold.

Affordable price, good design and fast heat transfer. This is the whole secret of the success of aluminum radiators. With strict adherence to the above-described norms of choice and exploitation, they will serve a long time with good heat efficiency.

The upper point of the evolution of radiators is a bimetallic heating radiator with the stated service life of 40 years. Bimetal is a combination of two or more types of metal in one product. Bimetallic radiators inside are made of steel, and outside are covered with aluminum ribs.

High-quality bimetallic radiators are necessarily covered with anti-corrosion primer not only outside, but also inside. They are able to withstand the pressure of 20-35 atmospheres and do not require special technical conditions for circulating water.

The bimetallic radiator concludes aluminum heat transfer and resistance to corrosion of the best iron alloys.

Bimetallic heating radiator in contextBimetallic heating radiator in context.

The reverse side is the high cost of these heating devices. There are also cheap models on sale, but bimetallic in them is only the name, if you decide to purchase such a radiator, then you should carefully approach this issue so as not to buy a fake of the lowest quality.

The use of bimetallic radiators in the storage systems of the private house is not entirely appropriate due to the high cost. Yes, they have much more strength than aluminum and metal radiators discussed above. But at the beginning of the material I have already mentioned that there is no high pressure in the local heating network, as a rule it is 2 - 3 atmospheres, therefore there can be no powerful hydrowards here as well. So it turns out that the advantages of this radiator in the form of increased strength in this case are not considered appropriate.

Cast iron radiators

The first cast iron radiators began to use even in Tsarist Russia, more than 100 years ago. Until now, in the homes of the Soviet era, you can meet a cast-iron radiator with 50 years of experience.

Cast iron heating radiator MS-140Cast iron heating radiator MS-140.

If aluminum radiators are quickly heated and get cool quickly, then with cast-iron batteries, the opposite is on the contrary. The residual amount of heat conservation in the cast-iron radiator is 30%. On the other, considered types of radiators, it does not exceed 15%. What makes it possible to significantly reduce gas costs for the heating of a private house.

The resistance to corrosion is very high, the performance of pig-iron batteries in old houses, indisputable proof of their durability and reliability.

If there are doubts about the design, the modern market can boast of exquisite decorative solutions that can decorate the interior of any home or apartment:

The cost of pig-iron radiators is higher than their aluminum and steel female, but much lower than bimetallic heating devices.

The only drawback of pig-iron batteries is their too heavy weight.

So we reviewed all the common heating radiators, which is better to solve in a private house yourself, using this article as a prompt, and not a guide to action. As you can see any radiators for the heating of a private house require certain operating conditions, and they need to be chosen by considering the overall technical condition and the possibility of the heating system itself, in general. Much depends on the budget, when choosing any type of batteries, you can find a golden middle characteristics and a price range.

In my opinion, in this case, it is most advisable to consider 2 types of radiators. These are panel steel radiators or aluminum. But after all, if they compare them among themselves, then probably steel is still more practical, more reliable, more efficient and cheaper.

When developing a project of an autonomous system for the heating of a private house, you must decide on the choice of batteries. The efficiency and efficiency of the heating system depends on their parameters, the level of comfort in the residential premises of the country house or country cottage. To determine which heating radiators are best suitable for a private house, it is necessary to compare their operational qualities, reliability and cost.

Radiator heating in a private house

When choosing a heating system for cottages or at home, you need to take into account the cost of installation, ease of operation and efficiency. For a brick, block, frame and wooden house, water heating is equally well suited. This option is cheaper to use compared to the installation of heating electrical equipment and more efficiently a conventional stove fuel for which coal or firewood serve.

Radiator
Radiator heating in the house

The radiator heating system for a country house or giving has an advantage over water outdoor heating, since the installation of the pipeline and radiators is easier and faster than to lay the outline and equip the screed.

From central heating, autonomous is different:

  • low operating pressure;
  • lack of risk of hydrowarders;
  • the ability to adjust the temperature of the coolant, to establish a maximum allowable;
  • the ability to adjust the acid balance of the coolant;
  • economy.

At the design stage of the autonomous system, determine which heating batteries and pipes are used for installation. It depends on its functionality, efficiency and durability.

Varieties of heating batteries

To choose to heating a private house radiators with best operational qualities, it is necessary to understand the virtues and disadvantages of heating batteries that the market offers. Consider each type of heating instruments follows from the properties of material and design features.

Radiators
Types of heating radiators

Radiators differ :

  • by manufacturing material (steel, aluminum, cast iron, bimetallic);
  • By design (sectional and solid):
  • According to the principle of heat transfer (radiating thermal energy, convection and combined).

Steel

Among the heating radiators for a private house, steel models made of steady demand. The list of advantages includes:

  • relatively low weight, which simplifies installation;
  • Quick heating and cooling - allows you to flexibly adjust the temperature in the room when using the thermostat, saving fuel;
  • rather long operational period;
  • A wide selection of models with different functionality and appearance.
Steel radiator
Steel Kermi radiator in the interior

The disadvantages of heat heating devices include:

  • The tendency to corrosion - such batteries are calculated on the installation in the heating system of the closed type as the free penetration of air into the coolant accelerates the process of metal destruction;
  • The tendency to the upstream due to the rough inner surface - the regular flushing of the system is required;
  • Restrictions on the characteristics of the coolant - adding alkaline reagents should be avoided.

To understand what steel heating device to choose, consider in detail every variety. Manufacturers offer sectional, tubular, panel and convect steel heating appliances.

Sectional

The battery consists of individual units, the number of which can be changed. This is a serious advantage of heating devices of this type. If the thermal calculation is incorrect and the radiator power is not enough, additional sections are added. If the house has been insulated and the need for powerful radiators disappeared, it is enough to remove unnecessary sections to reduce the energy consumption. The advantages of sectional models also include a stylish design that will fit into any interior. The disadvantage is considered a large number of joints, due to which the risk of depressurization of the battery increases.

Section radiator
Sectional heating radiator in the interior

Tubular

They are distinguished by the original appearance, convenient for drying things. Reliable and durable due to the absence of joints - the radiator is a one-piece design. At the same time, it is important to choose the proper heating device by power, as it will not be possible to correct this parameter.

tubular radiator

Panel

Panel-type heating radiators are characterized by a stylish concise design. Unlike tubular and sectional batteries, panel models, equipped with convective fins, heat the air indoors faster - the formation of a flow of heated air is added to thermal radiation. The possibility of creating a thermal curtain makes panel radiators in demand for installation in rooms with a large glazing area. Panel radiators, like tubular, are solid. Models of this type can not only be mounted on the wall, but also installed on the floor.

Rose panel radiator

Convectable

Water convectors consist of steel pipes on which numerous metal plates set by the edge are mounted. From above, the heating device is closed with a stylish metal casing. There are models embedded in the floor. The gaps between the plates contribute to the formation of the flow of heated air. Convector radiators are recommended to put along panoramic glazing, in the winter garden, indoors with high ceilings. Due to the natural convection, the room warms up faster than thermal radiation. Solving which radiators are better, it should be noted that for a system with water convectors, a smaller coolant is required compared to the use of other types of radiators. The disadvantages of convectable radiators include high cost. In addition, during the operation of such a battery, the air flows constantly raise dust, which falls into human respiratory organs.

Convector radiator
Outdoor convector

Cast iron

Considering different types of radiators, it is impossible to bypass the classic option - the cast iron batteries. Until now, working specimens installed before the revolution have been preserved in old houses. In the houses of the Soviet buildings are massively used cast iron radiators of the serial sample.

Benefits include durability and resistance to corrosion, high heat transfer, the ability to install additional sections. The list of disadvantages includes a tendency to the upstream - with the heat transfer of such batteries, it falls, since the free space is narrowed inside the case. Unlike modern heating devices, cast-iron batteries are required to regularly paint. Also, the disadvantages include a lot of weight gaining transportation and installation.

Before choosing a cast-iron battery for a private house, you need to pay attention to its high thermal inertia. It slowly heats up and cools, which makes it impossible to quickly adjust the microclimate in the room.

Today in private houses, radiators from cast iron are installed if they want to emphasize the individual image. Manufacturers offer original outdoor models, decorated with an artistic casting that perfectly complement the interior in the classic style.

Aluminum

Solving which heating devices are better to choose for a private home, pay attention to aluminum models. Such radiators enjoy the growing demand in private developers due to the low weight and ease of installation, attractive appearance, the ability to add and remove the sections. The cost of the product depends on the manufacturer. Domestic products are maximally available for the price, this is a budgetary dacha option. In a country house, put imported products, it is more reliable, but it is more expensive.

Aluminum radiators:

  • may leak due to the presence of threaded connections;
  • Aluminum is demanding for the acidity of the coolant - the use of liquid with unsuitable parameters displays the heating devices;
  • Due to the increased heat transfer, it can be bad to warm up the lower part of the room - the heated air quickly goes up and the floor remains cold.
But despite this, it is reasonable to choose a radiator from aluminum for a private house - the metal is quickly heated and cools, allowing to quickly change the level of heating of the room in accordance with weather conditions and microclimate requirements. In this regard, the battery from aluminum is the most practical.

Bimetallic

Such heating devices combine the benefits of steel and aluminum models. The inner surface of a durable iron alloy is undemanding to the characteristics of the coolant and ensures the structural strength of the battery. For external aluminum casing, good heat transfer is characterized, due to which the radiator effectively warms the room.

The bimetallic radiator is designed for high working and crimping pressure, which makes it an optimal choice for installation in an apartment connected to the central heat supply network.

Given the high cost of high-quality bimetallic models, in private heating houses it is better to use a budget option designed to work in the autonomous system.

Battery Power Calculation Principles

To select heating radiators for a country or private home, it is required to perform calculations based on the fact that for heating of one kV. The living area requires approximately 95-125 kW. To warm up the room with averaged parameters (one window, one door, the ceiling height is up to 3 meters) It is necessary to heat the coolant to 70 ° C.

If the real parameters differ from the specified, it is necessary to make amendments. For example, with ceiling heights, more than 3 meters need to increase the calculated battery power at as many times as the actual height is exceeding conditional. With low ceilings, recalculation is conducted in the opposite direction.

Reducing the temperature of the coolant for every 10 ° C relative to the specified averaged mark forces it to increase the calculated power of heating devices by 15-20%. If the room is an angular and two windows in it, the average calculation capacity of the batteries is 1.5 times.

The heat transfer of radiators largely depends on the circuit of their connection. The averaged calculation is based on the fact that the heated coolant is fed to the upper side input, and the reverse is connected to the bottom input diagonally. Other connection options are less efficient and reduced by the heat transfer of batteries by 5-10%.

Note! The number of sections in the radiator models of this type should not exceed 10 pieces - further extension will not help increase power, as the coolant will not be able to fully warm the battery.

Calculate the parameters of the radiator

Particularly closely close to the selection of panel and tubular batteries. Manufacturers include in the product line of the model of the same power, but with different geometric parameters. When choosing, the features of the installation site are taken into account - the height from the floor to the windowsill, the length of the wall in the elongated room, etc.

Homeowners choosing heating devices and wishing to acquire the best options for a spent price, stop their choice on steel or aluminum models. The cost of the most reliable, imported bimetallic radiator is exormably high, and cast-iron batteries have a lot of serious minuses. According to statistics, those who think about which radiators to choose into a private house or in the country, stop on aluminum sectional or steel panel models based on the price and practical ratio.
