Before proceeding with the assembly of the heating system country house, it is imperative to develop its detailed draft. In this case, first of all, you need to decide on the type of equipment required, as well as make all the necessary calculations. for a private house, how to choose the right boiler and pipes for highways, what type of wiring will be better in one case or another - read about all this later in the article.
To assemble a heating system in a country house, you will have to purchase:
radiators;
circulation pump;
pipes for highways.
You will also need to buy expansion tank... V modern systems heating is mainly used only membrane equipment of this type.
When purchasing batteries, first of all, you should pay attention to:
their design features;
maximum working pressure;
power;
number of sections.
Modern industry produces several types of such equipment. In specialized stores you can find batteries:
cast iron;
of steel;
made of aluminum;
bimetallic.
All these types of heating radiators are quite suitable for a private house. The choice in this case depends mainly on the operational characteristics of a particular system and the financial capabilities of the owners of the building itself.
The main advantages of radiators of this type are considered to be low cost and durability. Cast iron batteries do not corrode and can serve faithfully for up to 50 years. In addition, they are undemanding to the quality of the coolant and can easily withstand a rather serious pressure in the system - up to 12 atmospheres.
The advantages of cast-iron models, therefore, have a lot, and therefore, in some cases, they can be an excellent answer to the question of which radiators to choose for heating a private house. However, despite the large number of advantages, such batteries are rarely installed in residential suburban buildings. The thing is that Soviet radiators of this variety look too old-fashioned. Fit them harmoniously into modern interior almost impossible. In addition, these batteries are very heavy and can be used mainly only in buildings with very strong walls. For example, they are absolutely not suitable for a house built of foam concrete.
Cast-iron heating radiators for a private house are suitable, but, having decided to choose just such models, it should be borne in mind that they do not differ in particularly high efficiency. Such batteries warm up rather slowly, and their heat transfer is not particularly great.
Radiators of this type, in contrast to cast iron, warm up very quickly. This makes them easy ideal option for heating systems with regulation temperature regime... Everything else, and weigh steel batteries not too much. Therefore, they can be installed in buildings with walls made of any materials, including foam blocks or SIP panels.
Steel radiators for heating a private house, therefore, are quite suitable. Their only drawbacks are fragility and inability to withstand significant pressure. The second disadvantage for a private house usually does not play too much of a role. After all, the pressure in the pipes in such buildings is often not particularly high. If this indicator in the system does not exceed 7-8 atmospheres, buy steel models you can safely. However, in this case, attention should also be paid to the quality of the coolant. If an effective water purification system from a well or well is not installed in the house, you should still refuse to buy such equipment. When using a low-quality coolant, such radiators quickly rust and begin to leak.
Answering the question of which radiators to choose for heating a private house, it is worth considering, among other things, purchasing a relatively new type of steel equipment of this type, which has recently appeared on the domestic market. These are batteries made of stainless steel. Such radiators can last even longer than cast-iron ones, they are distinguished by high efficiency and attractive appearance. However, such equipment is, unfortunately, quite expensive. Basically, only owners of elite cottages can afford batteries of this type.
The main advantage of such radiators is their attractive appearance. Aluminum batteries look very modern and easily fit into almost any interior. They are inexpensive, but, like cast iron, they are rarely used in private houses. It's all about their increased demands on the quality of the coolant. In an acidic environment, aluminum reacts very quickly with the release of a fairly large amount of gas. And this, in turn, leads to the airing of the system and its failure.
Aluminum heating radiators for a private house, therefore, are well suited only when a sufficiently clean coolant is used in the lines. As for pressure, such models can easily withstand loads up to 15 atm.
Answering the question about which heating radiator is better for a private house, it is worth thinking about purchasing a model of this particular type in the first place. Bimetallic batteries are probably the most popular type of such equipment at the moment. The design of radiators of this type includes elements made of two types of metal - aluminum and steel (or copper). Hence their name. The advantages of bimetallic radiators, among other things, include:
the ability to withstand very high coolant pressure (up to 35 atm) and water hammer;
attractive appearance;
light weight;
durability (able to last up to 25 years).
In general, the best fit is bimetallic radiators heating for a private house. Reviews of models of this type available on the network indicate this unequivocally. Owners of suburban real estate consider such equipment to be very high quality, easy to install and operate. In appearance, such radiators resemble aluminum ones, but at the same time they are much more reliable. Their design is such that they look like a monolithic product. Insofar as performance characteristics such batteries are better than aluminum ones, they cost a little more (by about 25%).
The calculation of the heating of a private house should start with the determination of this particular indicator. The selection of radiators for a large cottage, of course, should be entrusted to specialists. If the system is assembled in a small one-story private house, this procedure can be performed independently, according to a simplified scheme.
total area of the room;
the necessary compensation for heat loss.
The latter indicator, when using a simplified calculation scheme, is usually defined as 1 kW of power per 10 m 2 of the room (or 1 m 2 100 W). That is, in order to find out what kind of batteries are needed in a particular case, you just need to substitute the desired value in the formula N = S * 100 * 1.45, where S is the area of the room, 1.45 is the coefficient of possible heat leakage.
Next, let's see how to calculate heating radiators for a private house using a specific example. This procedure is actually quite straightforward. For example, for a room 4 m wide and 5 m long, the calculation will look like this:
20 * 100 = 2000 W;
2000 * 1.45 = 2900 W.
Heating radiators are most often installed under windows. Accordingly, their required number is also selected. Houses with an area of 20 m 2 usually have 2 windows. Therefore, in our example, we need two 1450 W radiators. This indicator can be adjusted, first of all, by changing the number of sections in the battery. But, of course, in any case, there should be just enough of them so that the radiator fits freely in the niche under the window.
Power of one section in batteries different types may vary. So, for bimetallic radiators with a height of 500 mm, this figure is usually 180 W, and for cast iron - 160 W.
So, we found out which heating radiator is best for a private house. If desired, for a suburban building, you can choose both cast iron and aluminum, steel or bimetallic batteries. In this case, everything depends mainly only on the quality of the coolant, the pressure in the system and the features of the interior of the premises. However, when drawing up a project, of course, you should decide on the characteristics of other necessary equipment. In particular, it is imperative to calculate the boiler output. Modern industry produces four types of such equipment:
gas boilers;
electrical;
liquid fuel;
solid fuel.
These are the boilers for heating a private house. How to choose a specific type of such equipment is actually not a very difficult question. Most often, houses are installed. Installation of them is usually quite expensive. But at the same time, such equipment is quite economical and convenient to use. are cheap, but expensive to operate. Therefore, they are most often installed only if there is no gas main near the house.
Solid fuel and diesel boilers heating is used mostly in buildings built in remote areas. That is, where there is no gas supply and no power lines. Such equipment is usually quite expensive and, at the same time, not very convenient to use.
In order to determine this indicator, a specialist is usually also hired. You can try to calculate the power of the boiler yourself only for a small country house. As with the choice of radiators, in this case the fact is taken as a basis that 1 kW of boiler power is required per 10 m2 of the area of the room.
Heating lines can be laid different ways... Small country houses usually use simplest system"Leningrad" or dead-end two-pipe. In residential cottages of several floors, it is more often used collector circuit... In one-story houses of a very large area, a very efficient heating system called
When calculating the heating of a private house, this indicator should, of course, be calculated. With the wrong choice of the diameter of the lines, the system will not work effectively. To buy suitable pipes, you first need to decide:
with the thermal power of the system;
optimal pressure of the coolant.
The first indicator is calculated according to the formula Q = (V * Δt * K) * 860, where V is the volume of the room, Δt is the difference in air temperatures in the room and outside, K is the correction factor (depends on the degree of insulation of the building and is determined according to a special table) ...
The optimal speed of movement of the coolant in the system is 0.36-0.7 m / s. The obtained value of the thermal power and the selected pressure indicator should simply be substituted into the table for determining the diameter of the pipes.
As for the material of the highways, nowadays, both in small country houses and in cottages, metal-plastic is usually used. However, if desired, steel or even expensive and very durable copper pipes can be supplied in a private residential building.
When choosing this type of equipment, you should decide mainly on two indicators:
with working pressure;
with performance.
The second characteristic is calculated by the formula P = 3.6 x Q / (c x ΔT) (kg / h), where ΔT is the difference between the outdoor and indoor air temperatures, c is the specific 1.6 - dimension.
The required pump head can be determined by the formula J = (F + R x L) / p x g (m), where F is the resistance of the reinforcement, R is the hydraulic resistance, L is the length of the section, p is the density of the working fluid, g is the acceleration of gravity ...
An important link in any heating system is a radiator, which is installed in each of the heated rooms. It is this device that is responsible for how comfortable living conditions will be created in your apartment or private house.
Unfortunately, not every sales assistant will provide you with adequate assistance in choosing, so let's figure it out sequentially: how to choose the right heating battery so that it warms well, looks beautiful and does not "bite" at a price? It is not easy to answer this question right away - it is necessary to take into account many nuances. We will tell you how to avoid basic mistakes.
On the heating equipment market, heating radiators are represented by products that differ from each other both structurally and in materials of manufacture. When choosing them, you can use the table of comparative characteristics of the most popular heating appliances... The manufacturer indicates data for a specific model in the technical passport.
Comparative table of modern heating radiators
Very often, when choosing, the main criterion is the price and appearance. Undoubtedly, these points are very important. And yet, they shouldn't be decisive. First of all, attention should be paid to compatibility with the heating system in terms of such parameters as the type of heat carrier. The corrosion resistance and durability of the radiator is equally important. In the end right choice will save you money, time and nerves. Next, we will consider the features of each type.
Aluminum radiators stand out for their stylish, interesting design, and do not require special maintenance during operation.
High heat dissipation is combined with low weight, convenient sectional design and excellent performance. Considering that these factors are complemented by ease of installation and elegant design, it is not difficult to understand the reasons for the popularity of products from aluminum alloys in the arrangement of individual heating systems.
Comparative table of aluminum heating radiators of the most popular brands
When choosing an aluminum radiator, one should not forget that such equipment puts forward higher requirements for the quality of the coolant (water). Water with a high alkali content causes corrosion of the metal, and chemical reactions occurring during this process lead to gas formation. As a result, the service life of radiators is reduced and the risk of intersectional ones increases. For this reason, one should abandon cheap Chinese-made products in favor of products from well-known European manufacturers.
The probability of intersectional leaks is practically reduced to zero in the design of aluminum radiators from the STOUT brand. The equipment is manufactured at the Italian GLOBAL plant, the heating devices are adapted for the operating conditions in Russia. The working pressure of each radiator is 16 atmospheres, they are suitable for work with antifreeze and have a 10-year manufacturer's warranty. Modern design in Italian tradition will fit into any interior, and the increased area of heat radiation will increase the comfort in the room.
According to statistics, aluminum radiators have practically the same service life as steel ones - no more than 25 years, while bimetallic batteries can be used for 30-35 years, and cast iron products easily survive half a century.
The destruction of aluminum radiators most often occurs due to poor water quality and excess of the permissible pressure in the system.
Like the other heating equipment with open welded seams, require a stable coolant pressure. For this reason, they are most often used for installation in private houses and other buildings with autonomous heating. In this case, the closed heating circuit slows down the oxidative processes, moreover, it does not suffer from constant contamination of the coolant with alkali and other aggressive impurities. When using purified water and regular monitoring of the pressure, steel radiators do not need to be replaced for 20 years or more.
Technical characteristics of steel radiators from well-known European manufacturers
When installing steel radiators in buildings with central heating, one should be aware of the danger of water hammer and poor quality of the coolant. Sudden pressure drops and water with impurities of salts and alkali reduce the battery life by more than half. In this case, you should not expect the equipment to last more than 10 years.
Such deposits in the central heating pipe indicate a strong contamination of the coolant with impurities - in this case, it is better not to use steel radiators.
There are two types of steel radiators on sale:
The advantages of the former derive from the simple and reliable design, which resembles a ladder of parallel vertical tubes.
Tubular radiators are experiencing a second youth, being the object of attention of designers and hobbyists modern trends in the interior.
Tubular radiators are more resistant to water hammer than panel radiators. Their design allows you to implement any eyeliner scheme and arbitrary placement in space. In the assortment of tubular batteries, there are both monolithic and sectional models, from which you can easily assemble a battery of the required power. The simple manufacturing technology is reflected in the affordable cost, and the appearance of the radiator from many vertical elements gives a wide field for design research. At first glance, unassuming tubular radiators are not so bad in business, if you write your opinion about it in the comments, we will discuss it with pleasure?
Flat, flat surfaces panel radiators make maintenance much easier. That is why housewives love them so much.
For the manufacture of panel radiators, steel zigzag plates are used, which are spot welded to each other. The cavities formed in this case serve as channels through which the coolant circulates. To increase heat transfer, manufacturers complicate the design by assembling a radiator from three panels. Back side such an improvement is the heavier structure - the weight of multi-layer steel heat exchangers approaching cast iron.
For the manufacture of a panel radiator, profile steel plates are used, the space between which acts as a water circuit of the heat exchanger
As you yourself can see, the advantages of panel radiators, such as low price and attractive appearance, overshadow the disadvantages in the form of low performance. Most often, these heating devices are chosen for undemanding budget heating systems.
The appearance of copper radiators is suitable only for fans of industrial design, so manufacturers complete heating devices with decorative screens made of wood and other materials.
The pipe with a diameter of up to 28 mm is complemented with copper or aluminum fins and decorative protection made of solid wood, thermoplastics or composite materials. This option provides efficient heating of the room due to the unique heat transfer of non-ferrous metals. By the way, in terms of thermal conductivity, copper is more than 2 times ahead of aluminum, and steel and cast iron - 5-6 times. Possessing low inertia, the copper battery provides quick warming up of the room and allows the use of temperature control equipment.
In terms of its thermal conductivity, copper is second only to silver, by a significant margin ahead of other metals
The inherent plasticity of copper, corrosion resistance and the ability to contact with contaminated coolant without harm allows the use of copper batteries in apartments of high-rise buildings. It is noteworthy that after 90 hours of operation, the inner surface of the copper radiator is covered with an oxide film, which further protects the heater from interaction with aggressive substances. Copper radiators have only one drawback - the cost is too high.
Comparative table of technical characteristics of copper and copper-aluminum radiators
At the moment, heating radiators are made entirely of plastic, a kind of know-how. Russian engineers in Skolkovo are also working on this type of heater. Contrary to popular belief, in terms of reliability, plastic radiators are close to metal products, and in terms of corrosion resistance, they have no equal at all. Thermoplastic products have high mechanical strength, good thermal conductivity and wear resistance. Plastic radiators are lightweight and therefore easy to transport and install.
For those who doubt thermophysical properties plastic, we recommend that you remember the contours of water-heated floors made of cross-linked polypropylene. Its thermal conductivity is lower than that of rigid thermoplastics, and, nevertheless, this does not prevent the use of plastic pipes for building reliable and effective systems floor heating.
The simplicity of manufacture and, as a result, low cost make thermoplastic batteries an excellent offer for those who set themselves the task of saving money. A significant disadvantage of plastic heat exchangers is that they can only be used in systems with a stable pressure of up to 3 atm and a coolant temperature of no higher than 80 ° C. For this reason, the promotion of plastic batteries in our market is difficult.
In addition to the heating devices discussed above, there are others - those that do not require connection to the heating system. You probably already guessed what we are talking about.
Modern electric radiators combine high efficiency, reliability and safety.
Depending on the design, there are several types of heat exchangers operating from the electrical network:
The design of the oil cooler most closely resembles a traditional heating battery. Mineral oil is used as a heat carrier, and heating is carried out by a tubular electric heater (TEN). The closed design contributes to fire safety and mobility of the device, moreover, the oil heater does not burn oxygen and dust. The disadvantages include bulkiness, low efficiency and the possibility of getting burned when touching a metal surface.
Oil radiators differ from traditional heating batteries in mobility - if necessary, they can be easily carried from place to place
Electric convectors also use heating due to ohmic losses, only their design uses not a liquid, but an air heating element. Thanks to the closed design, this type of heater has the same advantages as oil radiators. As for the design, it is optimized so that the device uses convection as efficiently as possible. The disadvantages of the convector can be attributed only to low mobility - most often such devices are intended for stationary use.
Simple design and heat transfer by convection contribute to the reliability and efficiency of electric convectors
Infrared radiators are the most modern type of heating equipment. Unlike any other equipment, their design is based on the principle of heat transfer by radiation.
The principle of operation of infra-frame radiators is borrowed from the Sun - it is not the air in the room that heats up, but the reflecting objects
By heating not the air, but the surrounding objects, IR heaters are highly efficient and at the same time have the highest efficiency. The disadvantages of devices that work similarly to the Sun can be attributed only to the relatively high cost.
Unlike other radiators, infrared devices work most efficiently on the ceiling - in this case, the radiation penetrates into the most distant corners of the room.
The dimensions of the radiator affect not only whether the heating device can heat the room to a comfortable temperature, but also the efficiency of the heating system.
When determining the size of the radiator, among other factors, the width should be taken into account window opening and the height of the windowsill
The dimensions of the battery are in direct proportion to its thermal power, so the first step is to calculate the heat loss of the room. To do this, the volume in cubic meters is multiplied by 41 W - the amount of heat required to heat 1 cubic meter. m of a building located in middle latitudes. Add 20% to the desired value - this margin will not be superfluous when extremely low temperatures occur. Knowing the cost of heat, which will be needed to maintain a comfortable temperature in the room, you can choose a monolithic battery the right size or count the number of modular radiator sections. In the latter case, the resulting figure should be divided by the capacity of one section.
When determining the number of sections of heating radiators, you can use a special table.
For rooms with non-standard ceilings, an oversized heating battery is required. In this case, a table that takes into account the height of the ceilings will help to determine the number of radiator sections.
The table grows on click.
It must be remembered that the radiator installed under the window must cover ¾ of the length of the window opening. In this case, cold air will not accumulate near the glasses, and they will not fog up.
For those who do not want to deal with the calculation of power, there is a convenient one on our website. All that is needed in this case is to enter the parameters of the room and the heat transfer of one section of the selected radiator. The program will do all the necessary calculations for you.
Summarizing comparative characteristics different types heating devices, the following main points can be distinguished:
When, in the process of repairing or building new housing, the need to install new radiators is maturing, the problem of their correct selection arises. Errors at this stage lead not only to unreasonable costs and significant heat losses, but also to breakthroughs, premature failure of devices. Do not forget that the operating conditions and parameters of open and autonomous systems are markedly different. Overview of heating batteries for a house and an apartment, their comparative analysis and user reviews will help you choose the best set of equipment.
Heating radiators (batteries) are various in shape and size, but their main distinguishing feature is the material from which they are made. This is what determines the performance.
Battery requirements for home and apartment
An autonomous system is an undoubted advantage of a private house, since its parameters do not go beyond the calculated data. Due to the instability of indicators, centralized heating requires compliance with a number of additional conditions.
1. Batteries for home.
It is easier to choose a heating radiator for a private house, since a closed loop has the following advantages:
Taking into account the above-mentioned positive aspects, any batteries can be connected to home heating, giving preference to products with the highest heat transfer and an optimal ratio of quality and price.
The best battery choice for the home will be helped by a short comparison of battery performance on local systems.
2. Radiators for the apartment.
Good radiators for central heating must withstand the negatives of open design:
The quality of the coolant is a barrier that does not allow you to choose some types of heating batteries for an apartment. Excessive acid content leads to failure of aluminum radiators. Air bubbles, typical of open systems, corrode the surface of steel products. Copper is the least sensitive to composition: a protective layer of copper oxide forms on their inner walls. But this type is too expensive.
Comparison of cast iron and bimetallic heating batteries:
“A year ago, we replaced heating radiators in our 2-room Khrushchev building with bimetallic ones - the Global Style 500 model. Although, according to reviews, cast-iron radiators give off heat better, Global is much more efficient due to the shape of the sections. They are curved like petals and direct the heated air into the room. We even have to reduce the supply of heat - it’s good that there is a thermostat ”.
Victoria, St. Petersburg.
“Last year we were persuaded to replace the old registers with aluminum Halsen. They look good, are expensive, and we did not feel the effect of replacement. In the event of a power outage, the safety shutdown of the boiler is triggered. At the same time, the aluminum quickly cools down, so it was necessary to install 8-section batteries not only under the windows, but also along the walls. Gas consumption remained high. "
Alexander Kirillov, Tyumen.
“After reviewing reviews of good radiators, I decided to install flat wall steel Kermi... They quickly heat rooms, hang on the wall and are almost invisible, easy to maintain. The main condition is a clean liquid without air pockets. I put in an electromagnetic filter softener, before the start of the heating season I bleed the air through Mayevsky's tap.
Igor Fursov, Taganrog.
“Because of the hard water, I was afraid to put aluminum batteries in the house. A year ago, I came across neat cast-iron radiators from the Chinese company Konner with good heat dissipation (150 W). For an area of 115 m2, I had to buy 90 sections (with a margin). But, apparently, the manufacturer overestimated the parameters - it was cold in the house, while the system was working at its limit. "
Dmitry Kovalev, Novosibirsk.
“Modern bimetallic radiators are best suited for an apartment. I was convinced of this by installing the Syrah RS three years ago. They are specially designed for Russia: the steel filling is resistant to low water quality, and the outer shell made of aluminum gives off heat well. The design is attractive, there are no sharp edges - this is important since we have a small child. The height of the model and the number of paired sections (from 4 to 10) are easily matched. "
Leonid Kizilov, Moscow.
Selection by technical parameters
The main criterion when buying radiators is the compliance of their characteristics with the parameters of the system.
Comparison of heating radiators is carried out in a comprehensive manner, taking into account passport data and specific operating conditions, segment sizes.
If the choice of a suitable design has been made, it remains to choose a worthy company. Popular brands of bimetallic batteries are Italian Global Style, Royal Thermo BiLiner, Sira, Russian Rifar. Quality steel products are produced by Kermi and Zehnder. One of the best manufacturers cast iron radiators is a German company Guratec.

The construction market offers a wide range of devices for heating systems.
Asking the question: “ Heating batteries which are better for a private house? ”, you must first carefully study all the options, and then make a choice.
In contact with
To answer the question of how to choose the right radiator batteries for heating a private house, you need to determine the nuances that affect the choice. These include:
A distinctive a feature of the home heating system is its autonomous work. This is a closed circuit, which has a low pressure, due to which there is no water hammer. The coolant has a special quality, it can be controlled and changed, if necessary, the type and properties. If applicable solid fuel boiler, it is better to use radiators with high thermal inertia, which will smooth out fluctuations in the temperature of the coolant. In practice, batteries made from various materials are used. To decide which one is the best, you need to know their types and characteristics.
Modern manufacturing plants offer the following types of radiators for individual heating:
They differ not only production materials, but also structural characteristics.
Made from two metal sheets, which are connected to each other, and the coolant passes through the formed channels. The material from which such products are made is most often iron. It will be impossible to disassemble this design, therefore, to increase or decrease heat transfer, you need to replace the battery completely.
In this case, these are separate sections that are interconnected. Their the quantity can be changed, depending on the need to increase or decrease heat transfer. Materials for the manufacture of these products can be different.
Another type of heating devices is produced from steel - tubular. These are 2 collectors which are connected to each other by vertical pipes.
This is a construction filled special liquid (not the coolant that runs at the bottom of the radiator).
Have curved tube view, with metal plates attached to it. The structure is decorated with a special panel with slots through which air passes.
Knowing the nuances of each of types of batteries, you can pick best radiators for heating.
Given the characteristics of existing materials, one can say which aluminum radiators better to use. If you are looking for an inexpensive option, then the aluminum models are worth purchasing.
These are the lungs made in modern style products that have proven themselves well in heating individual houses.
Provided that the price is not fundamental factor, it is worth considering bimetallic options.
If you have babies, which may touch the radiator, it is better to install convection-type products with a protection panel or models hidden in the floor. As a heat source in a private house, steel or aluminum radiators are suitable.
When using the boiler, working on solid fuel, or stoves with a water circuit, the best option is cast-iron models, which have been tested by more than one generation. Despite their impressive weight, they ensure long-term preservation of the coolant temperature. Manufacturers began to produce such batteries with modern design solution , which greatly improved their appearance.
In the rating of radiators for heating a private house, bimetallic models are the first. This type is produced from two different metals: iron and copper or aluminum, thanks to which the radiators get the best properties from each component:
All these characteristics distinguish such models from those made from other materials.
The second place is occupied by aluminum products. The most popular are Italian and Hungarian brands, which have not only high prices, but also long service life.
The main disadvantage imported models are unstable to operating conditions in domestic realities. Russian manufacturers make cheaper aluminum products with high thermal conductivity.
Third place are occupied by steel and cast iron options manufacture of products. Each of them has its own advantages and disadvantages. The main advantage is the low cost of both types. Cast iron models also have the longest service life, and this is their main advantage over all other types.
Attention! To increase heat transfer, cast iron radiators should be washed every few years, since rust and debris accumulate in them.
When installing the system heating in wooden building you should be aware of the seasonal shrinkage of wood. Deformation of the walls in the autumn-spring period can damage the heating network. In order to avoid such inconveniences, heating risers are fixed using special connections. When choosing radiators carefully relate to such nuances:
To answer the question which radiators for heating wooden house
, I must say that there are no strict restrictions on the choice of products, it all depends on preferences owner and intensity of use heating network.
In wooden buildings several heating options can be applied: electric, stove or gas. For each option are selected their battery types.
In the case of equipment at home with a gas boiler, it is possible to use any of the options available on the market. What kind of radiators for gas heating better, it's up to the consumer to decide.
In size they meet various options batteries: there are standard, high up to 2 m, and low from 1.5 m. Sizing for heating radiators a private home is not an easy task. A lot is influenced individual characteristics premises. With large panoramic windows, low batteries or built into the floor are suitable.
Before buying heating appliances, you must calculate heat output considering the volume of rooms . When using screens and protective panels for decoration, the power should be increased.
Advice! When calculating the power, it cannot be underestimated; all roundings are made upward.
After preliminary calculations, you will be able to purchase devices that will meet your requirements, and will help you save your budget.
It is not possible to create a heating system in a private house without batteries. Equipment of this type provides warmth in the premises, which is very important for residents of Russia, since our climate does not allow you to feel comfortable all year round... This raises a reasonable question: what kind of heating radiators are suitable for creating autonomous systems in a private house? The answer can be given only after consideration appearance and technical characteristics of these products, which we will do in this article.
In country houses, heating systems are installed that are connected to the boiler. They differ significantly from central heating, typical for multi-storey buildings... First, in autonomous structures, the pressure is within 3 atmospheres. Secondly, in heating a private house, a heat carrier of a different type and quality is used.
Low pressure of individual heating systems virtually eliminates the possibility of water hammer. For this, it is also necessary to carry out the operation of the equipment in accordance with certain rules, thereby preventing the occurrence of various types of leaks and any destruction.
In the case of using water as a heat carrier, you should pay attention to its quality. An excessively hard liquid is saturated with salts. This causes the appearance of precipitation on the surfaces inside the radiators, which reduces the heat transfer coefficient and leads to a narrowing of the gaps of the tubular elements of the batteries.
The choice of heating radiators for a private house depends on the type of circulation. If your system is equipped with a pump, this allows you to install different types batteries. A prerequisite in this case is the volume of the system. The boiler must handle heating and the pump must handle the pumping.
In practice, the mentioned physical quantity is usually calculated when it is planned to install cast iron radiators, and the system has a certain scale, for example, it contains more than ten heating devices.
This kind of calculation turns out to be in demand in the presence of welded registers or tubular heating radiators made of steel. The aluminum battery, characterized as reinforced, contains about 0.4 liters of liquid in one section, and the cast iron MC-140 with a distance between the supply pipes of 500 mm - 1.45 liters.
It is quite difficult to choose batteries for installation in systems that are distinguished by the natural circulation of the coolant. Here it is necessary to select radiators with a minimum hydraulic resistance so that a slight pressure in the system ensures the movement of the coolant. You have to choose from four types of radiators:
Cast iron products are highly efficient, since they have the largest cross-section of collectors in comparison with other radiators. If you plan to create a heating network with a significant length, you will have to make preliminary calculations regarding the required amount of water. But it is also necessary to make sure that the boiler can handle the expected loads. 
If you are not interested in cast iron radiators, then you are most likely operating with old concepts, that is, you remember how such batteries looked before, which is quite wrong. Today on the market there are cast iron heating radiators for a private house of a wide range of designs, including different styles, among which there are such trends as retro and modern.
As for the choice in favor of aluminum batteries, it is recommended to purchase reinforced models of these products. This is due to the fact that such products are equipped with vertical collectors of large cross-section. For example, the standard version of a radiator made of aluminum contains 400 ml of heat transfer fluid, while the usual one - within 200 ml.
Welded registers are rarely found in current dwellings, but country houses they are installed quite often. This equipment has a low hydraulic resistance, therefore, it is also necessary to calculate the optimal volume of the coolant here.
Heating systems are divided into open and closed... Moreover, the first type is used less and less, since it is recognized as extremely unreliable. Such designs require the installation of cast iron, copper or copper-aluminum alloy radiators that can resist corrosion.
In addition, the installation of registers is necessary, but they still find their application only due to the fact that they have thick walls. In closed systems, it is possible to install any radiators, which shifts the priority of the selection of appropriate equipment towards boilers, heat exchangers and pipes.
As a source of heat, not only the usual devices for heating water can be used, but also alternative systems, for example, operating at the expense of solar panels... In any case, such structures differ in that they cannot heat the coolant to high temperatures, and this, in turn, leads to the need to install extremely low-inertia radiators in terms of heat transfer.
Typically, these devices include copper or aluminum batteries and copper-aluminum equipment. Aluminum radiators are the most affordable, while copper radiators are the most expensive. At the same time, devices made of red metal are distinguished by high heat transfer rates, which favorably distinguishes them against the background of other similar equipment.
At the same time, the radiators described above are suitable for heating systems equipped with condensing boilers.
Copper heat generators and copper-aluminum products are the best option for a private house when the boiler is also made of copper. This condition ensures the long-term operation of the system as a whole, if additionally installation of fittings and pipes, neutral in composition, is made, and a normal heat carrier is used.
It should be noted, however, that copper heat exchangers can function properly for a long time and in the presence of aluminum batteries. But systems based on them must be assembled taking into account the exclusion of direct contact between copper and aluminum parts by using neutral adapters. 
Along with low-temperature heating systems, structures are used that can briefly heat the coolant to high temperatures. This usually manifests itself during the operation of solid fuel boilers.
For such systems, mainly cast iron batteries are used, since they are characterized by a large mass. This allows this equipment to easily withstand extreme temperature changes, which is a common situation when using fuels such as coal and wood. Temperature differences are able to withstand and having a tubular structure.
Copper is somewhat problematic due to its properties. As a result, it is necessary to install radiators made of copper and on a copper-aluminum base, if the pipes are also made of red metal.
Heating system country house will be as reliable as possible if the appropriate fittings and fittings are selected. This should be related to the availability of grounding and the use of a quality substance used to transfer thermal energy, which can be, for example, antifreeze that is compatible with copper.
If copper radiators for heating a private house, for some reason you are not satisfied, you can purchase steel batteries or products made of bimetal. The installation of such radiators should be carried out in conjunction with the installation of filters and mud collectors capable of retaining rusted steel particles.
To eliminate the likelihood of the appearance of suspended matter in the coolant, you can resort to installing batteries with stainless steel collectors. However, this does not in the best way affect the cost of such products. As a result, heatsinks of this type will differ minimally in price from copper devices with better heat dissipation.
Today the market is saturated with a large number of models of radiators from various manufacturers. If any option is not suitable for technical specifications, there will always be a product that, in terms of its parameters, will meet the requirements as much as possible.
Basic tips when choosing batteries for a private house boil down to the following:
Depending on the cost of certain radiators, you can create another list of tips necessary when choosing a specific product:
If you want to create heating for your home by installing aluminum batteries, it must be borne in mind that this will require special preparation of the coolant, which can be antifreeze.
To the question of which heating radiators are better, the most reliable answers will be given by their owners, whose personal experience will help you decide and understand how to choose the best option for yourself.
Installed steel radiators, as I heard that they are ideal for a private house due to the low pressure in the system. He refused from cast iron, because they are mainly used in multi-storey buildings with a view to a centralized high pressure system.

On a summer cottage-type heating system or the like, where the pressure is within 1.5 atm., You can mount almost any radiators that will last a very long time, if you do not hammer on them with a hammer. It all depends on the price and taste of a particular person.
I also recommend thinking about controlling heating devices. Here it is better to choose those with low thermal inertia. Every good home radiator comes with a thermal head. These devices quickly heat up the room and just as instantly turn off if the temperature in the room rises due to the appearance of heat from other sources of energy.

My house is 2 floors, 300 sq. m, where the second floor is a warmed attic. I thought for a long time which radiators are best for heating a house. I sat on forums and information sites. I purchased the Hermann Thesi 30SE boiler. The floor will be warm anyway. Where I bought this equipment, it is also advised to purchase Royal Thermo aluminum products.
