The most convenient (and sometimes, the only possible) option for the arrangement of heating in a private house is the use of an autonomous type system that does not depend on the sources of centralized water supply. Accordingly, most of the works related to its organization, installation and service have to be addressed independently. That is the question: "What are the better heating batteries for a private house?" It is urgent and relevant for a huge number of homeowners.

From how efficiently and competently, the calculation will be made, the selection and installation of heating devices, not only the comfort of accommodation in it in winter, but also the amount of material costs associated with heating and home service are depeted. Therefore, to begin with, you must select the type of heating system that will be installed in it. She may be:

• Air.
• Water.

In the first case, the heating of the premises is made by means furnace calorificates or special electrical devices, among which enter infrared heaters.

The furnace heating is the cheapest and easiest way of heating, however, while it has a multitude of flaws, such as:

• Long warming period.
• Low heat transfer coefficient compared to other energy sources.
• High percentage heat loss (most of the heat with such heating goes into the chimney).

Electrical and infrared devices are a more progressive way of heating private houses, but their greatest drawback is high cost and inaccessibility for a larger number of consumers, as well as high costs associated with their operation.

A more popular and widespread option of the heating of a private house are water type heating systemsin which the heating of the premises is carried out by heating the water moving along radiators and pipes.

Their advantages in a private house compared to the centralized system include:

• Low network pressure;
• Lack of probability;
• Limited and adjustable heat carrier temperature;
• The ability to control the acid-alkaline coolant balance.

In addition, they are distinguished by ease of operation, efficiency and efficiency.

Types of materials and structural features

Answering the question of which radiators to choose for the heating of a private house, it is necessary to determine for themselves, from which materials they will be made. They can be made from metals of the following types:

• Cast iron

Radiators from it can withstand temperatures up to +150 degrees and pressure up to 6-9 atm. The thermal power of their section is 80-160 W. Use period: up to 50 years.

Pros:

- durability, strength and reliability;

- immunity to the quality of the coolant;

- the possibility of a combination of various number of sections;

- corrosion resistance.

Disadvantages:

- Large weight and rude appearance. But currently produced and models with original design capable of decorating any interior.

- High inertia, which will be a minus for autonomous.

• Become.

Some consumers choose which radiators are better for the heating of a private house, this question is given a unambiguous answer: "Only steel". And this answer is a completely objective explanation. Take at least a list of their advantages and advantages compared to the heating devices of other species.

These include:

- excellent heat transfer;

- small inertia;

- low price;

- Low weight and accurate dimensions.

Disadvantages:

- the need for periodic flushing (every three years);

- low working pressure (which is not a minus for the autonomous system, since it will be quite enough);

- The need for constant filling (otherwise they can rust).

Temperature limit: + 110 ... + 120 degrees. Performance pressure: from 6 to 10 atm.

• Aluminum

The best suitable for the organization of the heating of a private house For several reasons:

- They have a modern design;

- have high thermal power and inertia;

- Convenient in montage.

Can be operated at operating pressure of 10-25 atm. and limit temperatures up to +110 degrees. The power of the section in such heating devices reaches 200 W.

Please note that thermal power is not only their indisputable dignity, but also a weak place. " The fact is that with high heating speed, warm air quickly rushes upwards, which can lead to the fact that the temperature at the top of the room and the floor will differ much. Therefore, before choosing heating batteries for a private house from aluminum, you need to calculate what area to be to be dumping by taking into account all the features of the room. Otherwise, the floor can remain cold when using them.

• Bimetal

In this case, we are talking about batteries manufactured from two metals. Most often they have a steel core coated with aluminum. Instruments of the type have a large number of positive characteristics:

- have increased resistance to hydrowards;

- possess increased heat transfer and chemical resistance;

- have an attractive design and low weight, etc.

Work at a pressure of 35 atm. Maximum temperature: +120 degrees. Sectional power: from 170 to 190 W.

However, due to its high cost, they are not very well suited for the arrangement of a private house, in which the average in the heating system is 2-3 atm., As well as there are no hydrowards and a high pH of the coolant.

Carrying out an independent choice of heating radiators for a private house, also it is necessary to take into account the types of these devices depending on their structural features.

They can be:

• Tubular;

Constructs consisting of several tubes that are interconnected by collectors. Have an original design, a wide range of sizes and shapes.

• Sectional;

Collected from individual elements (sections). Made from various materials, including cast iron, steel and aluminum.

• Panel;

The design of this type of batteries includes one or more metal plates, between which the circulation of the coolant moving through the channels located in their inner part occurs.

Important: only steel radiators are tubular and panel.

• Convectable.

They are made of plates attached to the pipes of a straight or curved shape, which moves the coolant. There are water, gas and electric.

Water heating convectors refer to a separate class of heating devices, which are based on another principle of operation (are not radiators)

After selecting radiators, they need to be correctly installed. Different are described in a separate article.

Calculation of the number and type of batteries for a private house

Many specialists, before choosing heating radiators for a private house, recommended to make calculation, with which you can select the type of battery optimal for each specific case. At the same time, the basis of the energy required to heat the 1 square meter of living space is taken as the basis. This indicator, on average, ranges from 95 to 125 W.

Also in the calculation takes into account the parameters of the room. It is believed that in the room with the height of the ceilings up to 3 m, one window and the door, the temperature of the coolant in the system for its normal heating should be about 70 degrees. With the "shift" of these parameters in some of the parties to the calculation, it is necessary to make appropriate amendments.

For example: if the ceiling height is higher than 3 m, then you need to select the heating batteries with a power enlarged at as many times how this parameter differs from the specified one. And in the room with a lower ceiling, the power of radiators should also decrease.

With a decrease in the temperature of the coolant for every 10 degrees, the power of the batteries used should increase by 15-20%.

Another important factor: the location of the heated room. In the premises of the angular type, if there are several window openings, the total thermal power of the radiators installed there is 1.5 times.

Speaking about heating batteries - what better to choose for a private house and how, it is necessary to take into account the features of the device of the heating system of the house. In particular, in cases where the flow of the coolant is made from below, and the reverse is from above, the efficiency of radiators heat transfer decreases by 10%.

IMPORTANT: regardless of the design and principle of system functioning, it makes no sense to install heating radiators in the house, the number of sections in which exceeds 10 pcs., Since the energy accounting from the "unnecessary" ribs will be very low.

Comparison of batteries for a private house

In order to deal with which radiators it is better to choose for the heating of a private house, you can make a small comparative analysis, assessing the advantages and distressed places of each type:

Separately, consider the technical parameters of the heating batteries of various types and the possibility of their installation in a private house:

Variety	Performance pressure, atm.	Compatibility with a private house heating	Cost
Steel, panel type	6-10	Yes	Low
Steel, tubular type	8-15	Yes	High (on model with original design)
Aluminum	6-25	Yes	Low
Bimetallic	20-35	Yes	High (on the model of European production)
Cast iron	6-9	Yes	Low (with the exception of original decorative models)

Thus, the question of which better heating radiators for a country house can be answered, which is based on material, practical considerations and convenience in the installation. The choice should be made in favor of aluminum or steel batteries, which have many advantages and having a small price.
Also deal with what kind of heating batteries it is better to choose in a private house, will help the video.

Whatever high-quality batteries in the apartment still coming sooner or later the moment occurs when they have to change on new devices. And immediately the problem is the heating radiators what is better to choose for the apartment? Another case when a desire to establish new batteries appears - this is if the apartment has old cast-iron "accordions", which do not want to fit into the interior created by the hosts created by the hosts.

The modern market offers a large range of models of radiators made from various materials and having a quite aesthetic appearance. Comparing the design of modern devices with coarse cast-iron batteries or ineffective and poor-quality convectors, which were previously installed in apartments, of course, you want to see such novelties in our possessions.

Criteria for selecting radiators

It is necessary to approach the choice of modern radiators with full responsibility, since not all their varieties are suitable for installation, for example, in the central heating system. Some types have such characteristics that are designed for a pure coolant and a certain limit load, therefore it is simply not able to withstand the hydrowood, which, alas, are not uncommon in our utility networks. Other radiators, on the contrary, in the autonomous heating system will not show the entire potential in them.

In addition to the selection of radiators for operational indicators, it is necessary to correctly calculate the number of sections in batteries for each individual room, otherwise the efficiency of their work will be very low, and in the premises of the apartment will not be comfortable enough.

So, the effect of installing new heating devices will be expected to be high, if you consider all their operational nuances and perform all recommended technological rules of installation.

To date, several different types of radiators differing in manufacturing material and design:

1. Cast iron batteries, both old models and advanced, having an elegant modern or retro design.
2. Steel radiators - tubular and panel.
3. Bimetallic heating devices manufactured from two types of metal.
4. Aluminum quality quality.

When choosing batteries for installation in the apartment, you need to consider the following criteria:

• Maximum pressure in the central heating system in the local heating network, and the possible limit on which the radiators attracted is designed ..
• The maximum temperature and features of the coolant composition in the system, as well as the endurance of radiators to these effects.
• Material manufacturing instruments and its main physical characteristics.
• Designer battery design.
• The required radiator power - on the basis of this parameter, the amount and size of the sections needed for effective premises are calculated. These calculations are made with a support for the recommendations of construction standards and rules, and can be carried out in various ways that will be told later.

For a start, you can bring a small table, which although briefly, but quite informatively characterizes the main types of heating radiators. Well, then consider the main types more intently.

Views of heating batteries and their main characteristics

Cast iron radiators

Cast iron radiators are "long-livers", but do not lose relevance today, especially since they acquire an elegant appearance and improved characteristics. The batteries of domestic and foreign production are available on sale, and there are certain differences between them - they are a little later.

• The batteries from this material did not lose demand, despite the fact that other, more modern heating devices appeared, primarily due to the technical characteristics of the cast iron. It is not subject to corrosion, radiators are not afraid of hydrowards, as they have quite thick walls. Another advantage of cast iron in front of other materials, from which radiators are made today, is high heat capacity, that is, the ability to save the temperature for a long time, even when the external heating is disconnected.
• It is also positive that cast-iron batteries will excellently function not only in the autonomous system with high-quality coolant and controlled pressure, but also in the central heating system. True, it is necessary to immediately make a reservation about. That they are undesirable to install in autonomous systems working with electrocotors - operation can be too invalid in terms of high electricity consumption.
• Cast iron radiators, for example, which are quite suitable for installation in an autonomous open-type heating system, where the coolant is inevitably saturated with oxygen. For cast iron, this is not scary - the material is not subject to oxygen corrosion.
• The thick walls of cast iron heating devices not only retain the temperature of the coolant, but also increase the resistance of the batteries to abrasive wear.

• If the old batteries had one standard dimensional line, and for proper heating of the room, it was necessary to select the radiator solely varying the number of sections, then the instruments with different parameters of power are made today. This expands the possibilities of the integrated selection of the necessary radiators, both at the desired power and the design of the premises.
• In order to make the installation of old cast-iron batteries, it was necessary to drive the brackets into the wall, which means to damage her finish. Modern batteries are produced both in the mounted version and in the outdoor, with reliable legs. The latter are simply installed on the floor near the walls, and plug into the heating circuts.

• Many modern models of cast-iron radiators do not have to be periodically painted as it was necessarily with old batteries. On sale they come ready for installation, and already have a processed and painted surface, which is not needed to refresh the paint layer annually. To care for these devices, only wet soft fabric will be required, which dust likes from them or erased. It can also be noted that absolutely smooth surfaces of modern batteries are radically different from the rough sections of the old sample, so dust is practically not going to them.

• Some cast-iron battery models are produced in very original style of designer design, which allows them to enter them in any interior, even modern, even filled with "retro". It is possible to choose the heating devices in such a way that they will also become a decorative element of the design of the room, complementing and transforming it.

The main disadvantage of all radiators made of cast iron is their high weight. If you plan to hang them on the brackets, the latter must be securely fastened in the wall - and not every partition is even able to withstand such a load. In addition, to raise and hang such a battery, you will definitely need an assistant.

Cast iron radiators of domestic and foreign manufacturers

On the Russian market you can meet both domestic and imported cast iron radiators. European countries - Germany, Italy, Czech Republic, Spain and others are represented by its products in a fairly large assortment. These products differ significantly from Russian for some characteristics:

• Unlike traditional domestic MS-140 or MS-90, foreign products have smoother, well-treated exterior surfaces, and original retro-options are decorated with injection molding in the form of vegetable embossed ornaments.

• Import products have a higher thermal power with small dimensions. So, for example, with the same heat transfer, the volume of filling in the coolant section of the domestic battery is 1.3 liters, and Czech production is only 0.8 liters. Therefore, this option will be more compact and accurate.
• Foreign products have internal perfectly smooth cavities, which contributes to the normal circulation of the coolant, without high hydraulic resistance, and prevents the formation of dirt sediments and scale on the walls of the channels.
• Domestic batteries go on sale with primed surfaces and require painting, and imported immediately ready to install.

• The "minus" of foreign articles is their very high cost, several times higher than the price on the batteries of Russian production.

In fairness I must say that the release of more modern cast iron batteries is gradually being uploaded to us. In addition, the excellent cast iron radiators of European quality are issued in neighboring Belarus in the Minsk plant of heating equipment.

Output: For the conditions of the apartment, cast iron radiators are fully applicable, especially when connected to the central heating system, of course, taking into account the shortcomings characteristic of them.

Steel radiators

Modern steel radiators differ in both their design and design. They are usually made in the form of panels or pipes, arranged between themselves, so such heating devices are called tubular or panel. To sort out their designs and characteristics, you need to consider each of the types of batteries separately.

Panel steel radiators

Panel radiators consist of two steel sheets, which are given the desired form of stamping. The billets are then welded into the hollow panel and, if necessary, are equipped with special convectable elements - so that the vertical directional movement of the heated air, therefore, thereby forming a peculiar thermal veil from the cold, coming from the window.

Staining such a battery occurs after the assembly of all elements into the overall design. Collecting paint occurs according to a special technology that ensures the strength and durability of the coating.

ELSEN heating radiators

So that the steel batteries last as long as possible, the protective painting layer must be applied evenly. Therefore, acquiring this type of appliances, you need to pay special attention to the coating, since steel sheets may be subject to corrosion on damaged, unprotected paint areas.

Panel batteries are designed for a coolant having a temperature of up to 85 ÷ 95 degrees, as well as a standard pressure generated in a centralized heating system.

The number of panels and heat exchange convector "accordions" may be different

This type of heating devices usually has its own classification, which is based on the number of panels and convection heat exchangers in the finished assembly. The example is given in the table:

Panel radiators can differ quite strongly not only in the number of panels, that is, in the depth of the structure, but also by other dimensions. They can be from 400 to 3000 mm, and the height usually varies from 200 to 900 mm.

In addition, panel batteries are made with lower or side connections. The choice of this parameter is made depending on how the layout of the heating circuit pipes are located.

Panel heating radiators have their advantages and disadvantages that must be familiar with before making a decision on acquisition.

The positive parties of panel radiators include the following:

• Relative ease of installation of devices in the heating circuit. The radiator has a solid design, and it does not need to be collected from individual sections.
• Panel radiators are characteristic of rapid warming. A large area of \u200b\u200bthe panel itself and the edges of heat exchangers-convectors contributes to the effective heat transfer, so the room warms up quite quickly.
• Compact size and aesthetic appearance allow you to enter such a radiator in almost any interior.
• To fill the autonomous system with panel radiators installed in it, it will require a sufficiently small amount of coolant.

There are panel radiators and their substantial minuses to which the following can be attributed:

• They are reliable under normal pressure in the central heating system, but are not designed for powerful hydrowards, which often occur when the system is filling in the coolant before the start of the heating season. Such a test panel may simply not withstand. Therefore, if they are selected for installation in the apartment, it is necessary to use a special device for protection against excessive intra-system pressure - gearbox, which will smooth the load on the panel by taking a blow to itself.
• The internal surfaces of the panel often do not have an anti-corrosion coating, although directly contact with the coolant, and the durability of their use will depend on its quality. As is known, in the central heating system, the coolant is very often not distinguished by high quality, and may contain very active impurities that contribute to metal corrosion. Therefore, as a rule, the panel type of the radiator will not be able to be operated in such conditions for a long time, since the steel unprotected surfaces of the unstable to the aggressive medium.

Based on these considerations follows output that the installation of panel steel radiators in the apartment under the central heating system is undesirable.

Tubular steel batteries

Unlike panel radiators, tubular consist of several sections, but "tight" bonded with the help of welding. Therefore, they also do not need to be assembled, as they are purchased in the finished form, representing a complete design from a certain number of sections. Therefore, that the heating is effective, you need to calculate the required total power required for a specific area before purchasing such radiators, and from these considerations to select the optimal model.

The batteries of this type are calculated on the intrasystem pressure of 8 ÷ 10 atmospheres, therefore there will be no means for installing the gearbox, since the hydrowards in the filling of the central system can lead to emergency situations.

Steel radiators have the thickness of the walls of only 1 ÷ 1.5 mm, so the coolant quickly heats them, and the metal begins to transmit heat into the room. However, it should be noted that thin walls are both weak part of such batteries, as they are easy to mechanically damage.

Tubular structures are more racks to an aggressive medium of poor-quality coolant than panels, as they usually have an internal protective coating of polymeric materials. Therefore, they are less subjected to corrosive effects and, accordingly, with the normal remaining parameters of the system can be longer.

Tubular radiators may have a different, sometimes even "unexpected" dimensions. Thus, their height is from 200 to 2500 mm, the depth is from 100 to 250 mm, and the width may vary widely depending on the need for total thermal power.

Tubular radiators are produced in a wide variety of designer solutions, can be wall and outdoor. Moreover, they are installed both around the wall or window, and even in the middle of the room. To install in the center of the room, radiators are used, having a height equal to the height of the ceiling, taking into account the support legs. This option is used in the case when the room needs not only to heat, but also divide into separate zones.

• Some battery designs are equipped with wooden panels installed on top, and, in fact, representing a bench intended for different needs, depending on the location of the heating device. For example, if it is installed in the hallway, it can be used as a stool for arms, as it will be convenient for him to sit down. In the evening, on a wooden surface can be mounted for drying shoes.

Since tubular batteries are produced in different colors and in a variety, even sometimes unexpected design finds, they can be selected for any interior design.

The disadvantages of batteries with tubular design include only two main points, but quite serious, negatively affecting the efficiency and safety of the apartment heating system:

• A fairly low heat transfer, which leads to increasing energy costs, if the batteries are installed in the autonomous heating system. The design is quickly heated, but it has a property and quickly cool, so the heating boiler will work almost constantly, with minor interruptions. Conclusion - to establish them in the system of autonomous heating of a private house unprofitable.
• The elements of the radiator are connected by welding, the seams of which will become a weak place when the hydrowards occur. Therefore, to mount them in the contour of the apartment, connected to the central heating system, is also undesirable. If they are still selected due to the appropriate design, then it is necessary to install a gearbox that takes the load from a sharp pressure drop over.

Conclusion from what is said : Tubular steel batteries, despite their external appeal - not the perfect option. The installation of such radiators to the offline system will further increase energy costs, and to the central heating system - to an increased risk of emergency situations.

Aluminum radiators

Aluminum batteries have aesthetic appearance, but you need to immediately say that they are not very good for installation in the central heating system.

For autonomous heating systems, the optimal choice is high-quality aluminum radiators

Housing owners with autonomous heating, aluminum radiators are very popular due to elegant appearance and high heat transfer. In an autonomous system with stable pressure and high-quality coolant, aluminum heating devices are able to serve from 15 to 25 years - it is these deadlines that manufacturers usually indicate in a technical passport as minimal.

Radiators are calculated on intrasystem pressure up to 15 atmospheres and temperature of the coolant at 80 ÷ 90 degrees. They have excellent power (heat pumping) reaching up to 200 ÷ 210 W, and the volume of each of the battery sections is only 450 ml with a weight of 1 ÷ 1.5 kg. Section bonding occurs with a coupling threaded connection.

Aluminum batteries may differ in size. Thus, the range of the distance between the lower and the upper axis of the radiator can be 500, 350 and 200 mm. If you wish, you can find or order devices with a non-standard distance of 700 or more than millimeters.

The drawing scheme shows an inter-axle compound equal to 500 mm, with a total height of a 573 mm battery.

This type of batteries is made from aluminum alloy and silicon additives that give metal additional strength, but two in different ways - extrusion and casting.

When used for the manufacture of details of the casting technology, each battery section is varied separately by filling in a special shape with a cooked alloy. This manufacturing technique guarantees each of the sealing section.

• Batteries manufactured by casting technology are designed for pressure in the heating system to 16 atmospheres. During factory tests (crimping), the coolant is usually supplied under a higher load, which reaches 25 atmospheres, which indicates that the manufacturer provides consumers to the additional margin of the strength of their products. Alloy radiators can have various forms, but mostly they have a smooth exterior surface that contributes to a higher heat transfer.

• The second, method of manufacturing, according to the extrusion technology, is the forming of the sections by melting the melt through special dumps that set the configuration of products. As a rule, as a raw material here is the so-called secondary aluminum - a product of scrap processing. The quality of the metal is definitely worse, since the composition of the alloy is not so balanced, the presence of impurities is not excluded. Such aluminum is obtained by a more fragile, more susceptible to oxygen corrosion.

The finished sections are collected in the overall design, which, during operation, it is impossible to increase by building or decreasing - from the factory received the ready-made battery, which is a complete product. Repair such radiators are also not amenable to repair - this should be considered when planning the purchase. High pressure conditions in the system, poor-quality coolant, the likelihood of hydroudars - is clearly not for such radiators. True, the price of similar heat exchange devices is significantly lower than on cast.

• Another type of aluminum radiators is produced, but already possessing a high degree of purification of the raw materials and with anodic oxidation of surfaces. They are often called both anodic. In the manufacture of the original alloy, aluminum changes its structure several times - this process is performed to achieve maximum stability of the material to any corrosion types. Therefore, such batteries are not afraid of an aggressive environment of any coolant.

The sections of the anode radiators are manufactured using injection molding technology, and then assemble using threaded couplings and reliable seals. Such products can, if necessary, be disassembled, for example, to remove the damaged section, or extensive to obtain the necessary total thermal power.

The inner surfaces of the batteries made of anodized aluminum have the perfect smoothness, which contributes to the unimpeded circulation of the coolant. The working pressure of such radiators is much higher than that of ordinary aluminum, and can reach up to 20 ÷ 25 atmospheres.

Externally, the anode batteries do not differ from ordinary aluminum, but their cost is much higher. Therefore, acquiring this option of radiators, it is necessary to check the passport of the product, which is always attached to similar high-quality products.

All aluminum batteries have general "pros" and "minuses", which also need to know if it is decided to choose this type for installation in the apartment.

So, the advantages of aluminum radiators include the following qualities:

• High heat transfer.
• Small weight, significantly simplifying the stages of transportation and installation work.
• A variety of sizes from which you can choose the desired one.
• Aesthetic appearance that allows you to "implement" similar radiators in the interior of any style.
• Relative safety operation. When hitting smooth and smooth aluminum surfaces, it is more difficult to get injured than, for example, angular cast iron batteries - this quality is especially important if small children live in the apartment.
• Aluminum batteries are excellent "Friends" with thermostatic devices - it allows you to accurately adjust the temperature regime. This quality is especially important if an autonomous heating system is created in the apartment, since radiators thermoregulation devices contribute to economy consumption.

The following factors are considered the negative parties of these heating devices:

• High risk of gas formation in interior design channels (concerns conventional, not anodized aluminum batteries, cast or extrusion).
• Possible formation of leaks on the connection of sections without the possibility of repair - for extrusion radiators from secondary aluminum.
• Heat concentration in the edges of the device elements.

Some possible problems arising during the operation of aluminum batteries can be circumvented. For example, in order to inside the design, gases are accumulated, each radiator is recommended to install a special air molding.

General conclusion: If aluminum batteries are installed in an apartment with an autonomous heating system, they will suit any, based on the financial capabilities of the owners and taking into account all the shortcomings listed. If the apartment is connected to the central heating networks, it is recommended to choose exclusively radiators from anodized aluminum - it is more racks and to an aggressive medium, and to elevated temperatures, and to the pressure drops in the system.

Bimetallic radiators

Bimetallic radiators enjoy in our time the greatest popularity of all kinds of modern batteries, yielding, perhaps only traditional cast-iron batteries.

These heating devices are manufactured by a combined principle - they are collected from parts made of two different materials, which, in fact, is understandable and from the name. Thus, the outer part of the battery is made of aluminum having a maximum heat transfer, and the internal channels for circulation of the coolant - from a high-quality steel alloy that is not subject to corrosion. Aluminum outer surfaces have a protective enamel coating, which gives radiators aesthetic appearance.

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 P.c -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.

Some consider centralized heat supply in apartment buildings with the remnant of the Soviet era, and others by the undoubted blessing of civilization. But we all continue to use this method of heating.

The main element of such a system is the heating batteries for the apartment, which are under the window in the residential rooms of high-rise buildings. About their species and features and will be discussed in our article. We also briefly consider the main advantages and disadvantages of cast iron, aluminum, steel and bimetallic radiators.

As a coolant in centralized heating systems, heated to 95 ° C is usually used. Moreover, it is used not purified distilled, and technical with dissolved salts and additives.

As a result, the material from which the battery was performed in the apartment should have a long time to calmly transfer the effects and drops of temperature, and moisture, and the impurities contained in the coolant.

To live for many years, the battery for heating the apartment should:

• to withstand operating pressure up to 9 atm (ideally up to 12-15 atm);
• performed from metals resistant to chemical and electrochemical corrosion;
• have a high heat transfer.

Pressure in the apartment radiators ranges 4-7 atm. Much here depends on the floors of the apartment building, temperatures outside the window and the working conditions of the heating network. But when crimping and pressure can be briefly climbing up to 15 atm and higher.

All heating radiators are made from metals (aluminum or iron) - only they are able to withstand workloads formed in heating systems

Also, the heating device under consideration should be easy to install, have a presentable view and low cost. But, most importantly, he must have excellent characteristics on the heat transfer.

The main task of the radiator - give the room the warmth, which came on water pipes. The more effective it does it, the better the owner of the apartment.

There are two main criteria for the classification of heating batteries:

1. Production material.
2. Constructive execution.

All other parameters are already the technical characteristics of a specific radiator model.

Features of different designs

The functionality of heating radiators affects not only the material from which they are made, but also their design.

So, constructively batteries are:

• sectional (block);
• columns (tubular);
• panel.

The first two options are a set of several elements assembled into a single heater, and the third is a monolithic unit.

Sectional instruments of water heating include widely common aluminum radiators. A classic example of a column analogue is an old cast-iron battery.

Option # 2 - Practical Steel

Steel batteries are distinguished by practicality and there are two species - tubular or panel. The first is a direct analogue of the cast iron instruments described above. They have similar in heat and weight, but a more presentable look.

The second is made of two steel sheets cooked with each other and forming an inside a thin layer-cavity to circulate water.

This option is higher than the return indicators of heat, so they are often connected together by several pieces. As a result, the total heat transfer area increases sharply.

Option # 3 - Durable aluminum

Aluminum radiators are today the most common household heat engineering market. This is due to their cheap, durability and ease of weight, as well as the extreme simplicity of installation.

Among the advantages of aluminum radiators should be allocated:

• high heat transfer rates;
• low weight of the heating device;
• modern design;
• available cost;
• the possibility of configuration to the thermostat;
• service life of 30 years;
• lack of predisposition to paint delay.

The main disadvantage of the aluminum heater is a demandingness to the characteristics of the coolant. The slightest solid suspension during water circulation begin to scratch the protective coating inside. As a result, aluminum remains without protection and begins to gradually corrosive.

These batteries were originally created to replace old cast iron. They were immediately designed taking into account the features of the centralized heat supply existing in Russia.

No wonder they are called universal radiators that can be installed without any problems in any apartment.

The advantages of the radiator from the bimetal are as follows:

1. Reliability - operating pressure in the area of \u200b\u200b35 atm.
2. Neutility to the chemical composition of the coolant.
3. High corrosion resistance.
4. Compactness and modern appearance of the device.
5. Small weight.

The main and only substantial minus of this device is a high price.. They are the most expensive among all the analogues. However, these costs will definitely blocked the long service life and the absence of leaks with floods.

Especially bimetallic radiators are relevant in homes where frequent water pressure drops occur in the heating system.

Conclusions and useful video on the topic

To make it easier for you to figure out which radiator is better, we made a selection of video materials with the analysis of different nuances of these devices.

The following roller will help to deal with the varieties of radiators and determine which better suited for specific operating conditions:

Choosing what battery to put in an apartment, it is necessary first of all to navigate the parameters of the central heating system.

In the old house it is often possible to establish only cast iron radiators. Aluminum options are ideal for new buildings and panel five-story buildings. And reliable bimetallic analogues are universal devices that are suitable in almost any situation, but worth a lot.

And what batteries consider the best you personally and what are installed in the heating circuit of your home / apartment? Share your impressions from their use, add unique photos of your radiators and useful recommendations to beginners.

Everyone who is dissatisfied with heating in their own house, a reasonable question arises: how will the batteries replacement on the temperature mode? If you live in the house of an old housing stock, then the replacement of the heating devices can dramatically change the situation. It is only necessary to solve correctly, for the apartment and for what criteria are to select them. This will be discussed in our material.

Is it worth abandoning the central heating and which radiator is better to choose for heating an apartment

Before talking about how to choose radiators for heating apartments, let's figure it out with the main point: what is better, central or heating?

The question is not idle. These systems have different operating hours and specific operating conditions. From what choice you do, the type of heating devices depends.

Previously there were no options. In apartment buildings there has always been centralized heating. This in modern new buildings almost all developers offer an individual system operating or.

Compare the advantages and disadvantages of two systems:

Central	Autonomous
pros
Stable temperature in the apartment all heating season.	You can adjust the temperature mode depending on the weather.
There is no need to invest in periodic repair and maintenance of the system - all this is laid in the cost of utilities services.	Heating in the apartment can be included, without waiting for the official date of the beginning of the heating season and turn off later or earlier, as it will be necessary.
This method of housing heating is most comfortable and safe.	You can adjust the temperature in each room separately.
The system is independent of interruptions and. In large boilers designed for apartment buildings, there are reserves of maintaining work in emergency situations.	When using an autonomous heating system, you will significantly save your budget. In addition to lowering the costs due to temperature control, you can use the system for.
Minuses
Prices for heating in a centralized way are quite high, in addition, the costs of the service are included and the costs "for that guy", unaccounted heat loss	To establish autonomous heating in the apartment, you will need a long process of coordination with numerous instances.
Heating include and turn off in strictly defined dates, without taking into account weather conditions and wishes of apartment owners	To install the system, capital investments will be required, after installation, it is possible, you will have to do in the entire apartment.
Adjust the temperature in the rooms and save on heating will not work.	Autonomous heating depends on the uninterrupted supply of electricity and gas.
The safety of your dwelling depends on the locksmith of housing and communal services. If he is inexpressive or too sharply close the faucet, which occurs hydroplates will destroy the batteries and will result in damage.	The boiler in the apartment requires special security measures. The system needs to be monitored, conduct periodic preventive inspection and maintenance.

Now that you have an idea of \u200b\u200bthe weak places of both heating systems, you might think about how to choose the heating batteries in the apartment.

There is a proven practice list of key criteria for heating batteries-radiators. How to choose instruments:

1. Pay attention to the working pressure indicated by the manufacturer in the product data sheet. Compare it with the indicators of your centralized or autonomous system. For information: in the standard five-story building, the average pressure rate is 6-8 atmospheres, in houses for 9-12 floors - up to 15 atmospheres.
2. It is important to select devices resistant to possible hydrowood. The harbingers of the accident may be a buzz and noise in the pipes.
3. The radiator material should be resistant to chemical exposure, rust occurrence and mechanical damage.
4. The heating instrument model should be selected at the maximum coefficient. It is specified in the technical documentation.
5. Radiators are characterized by a service life. If you do not want to spend time on replacing batteries - select those. What have a maximum warranty period.
6. And the last, but important factor is an appearance. Pick the devices according to your window opening and arrangement.

Types of heating radiators for apartments and their features

Each type of heating batteries in the apartment has its own characteristic features. They differ in the material, the specifics of the design and the allowed pressure.

Table of basic parameters:

Material radiators	Warranty period, years	Permissible pH coolant	Working pressure / Pressure pressure / Destruction pressure
Cast iron	10	9	9/15/25
Steel	1	9	12/9/18
Aluminum	3-8	8	20/30/50
Bimetal	3-10	9	35/57/75

These four main varieties of radiators are most in demand in apartment buildings. Let's figure it out in the advantages and disadvantages of each.

Cast iron: Weight and for centuries

Cast-iron batteries are at least one hundred fifty years, and rare exhibits can be used in direct appointment today.

Advantages of pig-iron radiators:

Advantage	Description
Resistance to corrosion	The inner surface of the radiator from water contact is covered with an oxide that protects the metal from contact with oxygen. So that such batteries do not rust outside, they are enough enough to paint.
Neutrition for the coolant	The cast iron calmly transfers the presence of sand particles, does not capricious due to the pH level. Thick walls, resistance to chemicals and high temperatures make it one of the most reliable materials.
Ability to connect with other materials	Cast iron batteries can be shrinking with steel and plastic pipes. The material perfectly withstands the hydrowood to 25 atmospheres.
Maintainability	Cast iron batteries can replace the sections if necessary. Such batteries can be cleaned from the inside and disassemble.
Long service life	Such radiators are able to last at least half a century, and with due care - and more.

Models from cast iron have their own flaws that should be known before making a choice:

Disadvantage	Description
Slow heating	The cast iron warms very slowly, so that from the moment the heating to normalize the temperature regime in the room may pass half an hour - an hour. But he cools down for a long time, keeping warm.
Small heat transfer	In comparison with the models of steel or aluminum, the heat transfer of cast iron is less than one and a half times.
Big weight	Each section of such a battery weighs a minimum of 6 kilograms. Plus the weight of the coolant - about another kilogram.
Cost	The prices of cast-iron heating batteries are not the most democratic. The cost of the section begins from 500 rubles.

Opponents of cast-iron batteries may argue that this is not the most aesthetically attractive device. And by the way, will be completely wrong, see which masterpieces offer modern producers, can we compare them with primitive aluminum radiators and steel?

Steel: attractive but unreliable

Now you can buy steel heating radiators in almost every household appliance store. And recently they were in a novelty. Most buyers and with the advent of the counters began to use mad popularity. It is understandable: such batteries look unbearable and neatly, not a couple of cast iron monsters, which were in Soviet apartments.

The main benefits of steel batteries:

Advantage	Description
Good thermal conductivity	Steel panel radiators of heating thin walls, it allows them to warm themselves very quickly.
Long service life	The design of steel radiators is very primitive, due to this they can work up to ten years, subject to careful care.
A light weight	The weight of steel tubular heating radiators - 3-4 kilograms. They are easy to assemble, you can connect with the pipes of the coolant in several ways.
Cost	The price of steel models is low and is available to most consumers with average sufficiency. The cost of one section is from 300 rubles.

Steel batteries cannot extend as cast iron. And this is not the only drawback of such devices:

Given all the above disadvantages, it can be concluded that steel radiators are not suitable for central heating systems. They can only be used for autonomous heating in an apartment or a private house in a couple of floors.

Aluminum: Revolution in heating

Invalid aluminum batteries have excellent characteristics. They appeared relatively recently, in the sixties of the last century and over the years have proven well-established. Before you decide what to choose an aluminum radiator, read the characteristics of models of different manufacturers. They may differ in the level of heat transfer.

Average heat transfer indicators of aluminum radiators, Table:

Returning to the question of using different types of batteries in apartments with autonomous and centralized heating, it should be noted that in the rating aluminum heating radiators occupy no last place. They have their own advantages:

Advantage	Description
High heat transfer	Low inertness of aluminum as a result gives excellent characteristics of heat transfer. Aluminum batteries are very quickly heated.
Temperature adjustment	Radiators made of light material are equipped with thermoregulation devices. This allows you to install different temperature regime in the premises.
Easy to install and transport	Aluminum - lightweight material. Such batteries can be switched even on frame walls. If necessary, you can add and remove the sections.
Crab variability	Aluminum batteries have a wide range, it is not difficult to choose a radiator suitable for sizes and design for your design.

At the same time, there is a spoonful of the honey in this barrel, which will not allow the use of aluminum devices for central heating systems. So disadvantages:

Disadvantage	Description
Constant pressure	For normal operation, aluminum radiators need stable pressure to 10-12 atmospheres. Such conditions are difficult to maintain in a large central heating system.
Chemical influence sensitivity	Oxygen enters a chemical reaction with aluminum. As a result, hydrogen is formed, which causes air traffic jams and noise in batteries.
Election in materials for installation	Cannot be used for fastening brass, steel or copper fittings. Contact with these metals lead to corrosive processes in the radiator and the formation of surface discharges. Such batteries need to be grounded at mandatory.

Conclusion from all this information is one: aluminum - excellent material, but it is only suitable for an autonomous heating system. For the central it does not fit.

Bimetallic batteries: compromise

Bimetallic such radiators are called due to a special design consisting of tubular steel and aluminum. The combination of these two metals allows you to create devices worthy of competing with the strength and reliability of cast iron. This invention has been more than 60 years, this time is enough to determine the operational features of the device. The main characteristics of heat transfer of bimetallic heating radiators, Table:

- This is a monolithic panel without welded connections. And since there is no welding, it means there will be no leakage.

Advantages of bimetallic radiators:

Advantage	Description
High pressure resistance	Construction monolithium allows bimetallic radiators to withstand pressure up to 75 atmospheres
Chemical impact resistance	The insides of such radiators are treated with the composition that does not give water and oxygen contact with the metal
High heat transfer	Such batteries are quickly heated and perfectly give warmly.
The possibility of thermoregulation	Modern models are equipped with special devices for adjusting the temperature, which allow you to quite accurately control the climate in the room.
Ease and decent registration	Bimetallic light and stylish radiators. They are easy to install and are suitable for any interior.

It would seem, that's a simple answer to the question, what better heating batteries for the apartment: bimetallic. All in them is wonderful, but there are a couple of essential flaws:

Thus, bimetallic devices are excellent for central heating systems. They are a model of modern technologies and high efficiency.

Article on the topic:

From the publication, you will learn the area of \u200b\u200bapplying devices, their design, varieties, selection criteria, how to correctly calculate the number of sections, manufacturers and models, installation secrets.

How to determine the number of radiators for the apartment

To calculate the number of sections of heating radiators, two main values \u200b\u200bwill be known:

• the heat loss of the room (depends on the region used building materials and the size of windows and doors);
• the power of one radiator section (indicated in the product specifications).

For your information!The radiator suggestion usually indicates the maximum heat transfer of the device.

The easiest way to calculate the number of battery sections by software. To do this, multiply the height, width and length of the room. The value obtained is the area. To determine the amount of heat for the heating of the room, the result is needed to multiply to the regional norm. For the middle strip of Russia, it is 80 W, for the north - 150, south-60.

But it will be only an approximate calculation, without taking into account the material of the walls. The resulting need for heat should be divided into the heat transfer of a single battery section. As a result, you will receive the required number of sections. For calculation, the heat transfer table of heating radiators with average indicators is useful:

You can go even easier. Just take into account that one cast-iron section heats 1.5 square meters, aluminum - 2, bimetallic - 1.8. If you have a room, let's say, in 15 squares, then draw out: you will need 10 sections of the cast-iron instrument, 8 - aluminum and bimetallic.

But this, we will remind, just approximate calculations.

Important! Selecting radiators, be sure to consider the pressure level in central heating batteries.

What heeping radiators are better to put in the apartment - to solve you, but if you choose the products of one of the listed firms - you definitely do not lose.

RESULTS

The choice of suitable radiators is not such a simple task, as it seems at first glance. The type of heating system, the technical characteristics of products and the need of premises should be taken into account.

The heating season is already close, and you still have not acquired with heating radiators? It is necessary to hurry, because few people want to catch cold in a cold apartment. Many users are interested in one important question: how to choose heating radiators by area? There are many nuances with whom we will have to meet. Each heating element needs to be selected, starting with determining the amount of heat released, which is required for an apartment or at home. This important indicator can be calculated in different ways, starting with the easiest and most complicated. The easiest involve the use of the area and the height of the room. Let's find the most accurate and optimal of all.

Classic definition method

How to choose a heating battery in area if the height of the room is less than three meters? Everything looks like this:

1. At first, it is necessary to determine the size of the room in which this radiator will be placed. For example, take 25 square meters.
2. Multiply the resulting digit to 100 W. For our case, the result will be 2500 W.
3. We take the power that turned out, and divide it on the heat transfer of only one section of the device.

With panel radiators, the story will take a little different look. Panel batteries are one-piece design, which will not be able to increase or decrease in size, so the power will have to be considered complete. The installation of such devices with a capacity of more than 2500 watts will be a huge mistake, since the calculation method will look quite different.

Some features of the standard way

For accuracy of calculations, you need to enter the following adjustments:

1. The final value should be increased by 20% if the room is an angular, that is, has two external walls.
2. Total power increases by 10% if the connection type is lower.
3. The total amount of heat should be reduced by 15-25%, if there are metal-plastic windows in the room.

Important! For each cases, the desired number of percent is added to the final power. If each of these criteria takes place, the value of 2500 watts will turn into 2625 watts, then you will need to purchase a heating device for 18 sections.

Easy way

If you follow the instructions, then one edge of the radiator will be required for heating two square meters. It should also be paid to the fact that the total number of edges will have to add one more. For those cases where the room has a size of 25 square meters, you will have to take a device with 12.5 ribs. It is necessary to round the value and add another unit to it - it will turn out 14. As you might notice, this result is less than the number that was obtained by a classic method for the same room.

Of course, the absence of three sections will affect the heating of the room, which is why this method of calculation should be used only for an indicative result. Do not take the resulting values \u200b\u200bas a basis for selecting the radiator.

Important! Planning to install heating devices yourself? We have prepared a lot of useful and cognitive information on this topic:

Calculation for the second type of heating fixture

How to choose a heating radiator for a private house around the square if you need a panel type of device? For this method, there is not enough single room area, it will also require its height, as well as the coefficient 41. According to the battery standards, it is necessary to create 41 watts per unit cubic meter, as you can see, we will need to make mathematical actions with the volume.

The algorithm looks pretty simple:

1. Determine the area of \u200b\u200bthe room.
2. Consider the volume. To do this, simply multiply the area to the height.
3. The resulting value multiply the coefficient 41.
4. The end result must be corrected by the criteria that were described slightly above.

Important! After all actions, you must get the required power at the output. You can set one powerful heating device to achieve the target. This option will be acceptable for those rooms in which there is one window, but if they are two or more, it is better to use the action of two panel batteries with a 1250 watt heat transfer.
