Batteries for heating in an apartment which are better. Steel radiators. Bimetallic, aluminum and copper batteries - high heat transfer and reliability.
The choice of heating radiators, as in a private house, and a state apartment - a very responsible occupation. But only one desire and the necessary amount of money in order to buy the best battery is far from enough. It is necessary to understand the technical characteristics and basic parameters of heating radiators that will meet the criteria of the room.
Even despite the external similarity of many models of heating batteries, they may have different heat transfer coefficients, prices and other important parameters. It all depends on the materials used in the manufacture of the device., features of its design, method of installation and internal volume of the radiator. Therefore, in order to find out which heating batteries for the home are the best, you need to consider separately the main models on the modern market.
Criteria for choosing the type of heating battery
The advantage of private housing construction is the ability to calculate and install autonomous heating based on the preferences and needs of the homeowner. Therefore, in choice the best radiator for heating a private house is much easier than buying a battery to an apartment in a multi-storey building connected to a centralized heating main. Wherein autonomous systems Heating systems have a number of advantages:
- heating operation at minimum pressure in favorable operating conditions;
- the absence of strong water hammer, as in the case of central heating, which greatly expands the range of suitable radiators;
- if the heating system uses a coolant with balanced acid characteristics, then there are simply no restrictions on choosing a radiator for heating a private house.
For autonomous heating systems of private housing construction, the choice of a suitable heating battery should be based on the maximum heat transfer coefficient that almost all modern radiators have. Therefore, what kind of battery - cast iron, bimetallic, aluminum, steel or copper choose for home heating an individual choice of the homeowner. But still, there are some nuances of this issue that you need to know.
Cast iron heating battery
The cast-iron radiator has been used in different systems heating, both private houses and public apartments, and so far there has not been a worthy competitor in terms of service life and resistance to corrosion. With high heat transfer coefficient and low cost, a cast-iron battery was the only device for heating apartment buildings during the Soviet Union.
Such a device retains the accumulated heat inside for a long time in the event of an emergency shutdown of the central heating supply. She is not afraid of increased pressure, water hammer or low-quality coolants. Even water with a high alkali content, rust and air plugs do not cause great harm cast-iron radiator, which cannot be said about other batteries. Moreover, such a product has a relatively low cost.
Among the shortcomings of cast iron radiators, I would like to note them external unattractiveness, high weight and high level of inertia, which makes it impossible to use them in heating with thermoregulation. Although the external component of the device has long been decided, releasing models in retro style with copper and other precious metal finishes. Thanks to this, such an element of the heating system has become a design object of any interior.
Aluminum heating radiator
Aluminum radiators today have firmly taken their rightful place in the market of heating systems. Thanks to the sectional design of such a battery, the consumer is able to select the dimensions and parameters of the radiator himself, depending on the dimensions of the heated room. The high heat transfer coefficient, minimum weight, visual appeal and ease of installation of such a radiator made it a leader in individual heating systems.
Before choosing an aluminum radiator for heating private houses, you need to know some features of the choice and operation of such a device.
- Aluminum radiators are very sensitive to the parameters of the coolant used.. If the level of acid-base impurities in the water circulating through the batteries is not observed, this can lead to their destruction.
- Due to the high heat output of the aluminum radiator there is a rapid rise of warm air currents upwards, which leads to a noticeable temperature difference between the floor and the ceiling. Therefore, in order to have a comfortable floor level in a heated room warm temperature it is important to take into account this feature when calculating the number of battery sections depending on the area of \u200b\u200bthe room.
Relatively low cost, attractive appearance and maximum level heat transfer - the main criteria for the popularity of aluminum heating radiators for private homes. If you choose and install the aluminum battery correctly, it will last for a sufficiently long period of time, warming up the rooms in the house with high quality.
In heating systems of private houses, steel batteries are very popular. Such heating elements can be either tubular or sectional type, so, and are made in the form of a solid panel of a rectangular shape. At the same time, many consumers believe that steel batteries are the best for heating rooms in a private house. When choosing a steel product, the aphid of the heating system needs to know what advantages it has over competing analogues:
- low price without sacrificing a good heat transfer coefficient;
- high resistance to low-quality coolant;
- large operational resource;
- easy installation and light weight.
If we consider the disadvantages of a steel battery, then I would like to note the following problems:
- not the most attractive appearance although it is an element heating system, not a design object;
- the need for regular flushing of the steel battery at least once every 3 years;
- it is important that the steel radiator is always completely filled with coolant, otherwise the device will quickly become unusable due to the formation of rust.
The principle of operation of a steel panel battery is based on convection and radiation of thermal energy.
Heat transfer occurs both directly through the steel surface of the product, and through the lattice housing in the upper part of the device. If we consider the indicators of working pressure, then steel batteries withstand up to 16 atmospheres, which directly depends on the thickness of the material used in the manufacture. The maximum temperatures that such a heating element can withstand can reach 110 ° C.
Bimetal device - a modern and practical battery
If we consider the design of a bimetallic product, then it includes steel pipes and aluminum fins. Such a battery can be used both in private sector houses and in multi-apartment buildings. with centralized heating system. The circulation of the coolant in such a device made of seamless pipes occurs in such a way that the metal structure is not destroyed due to corrosion.
Thanks to aluminum fins, which have a maximum heat transfer coefficient, the bimetallic radiator quickly warms up the room. It turns out that such a battery has incorporated the best qualities of steel and aluminum counterparts. Corrosion resistance and unpretentiousness to the quality of the coolant were borrowed from the steel product, and high heat transfer and attractive design from the aluminum battery.
The bimetallic battery contributes to the uniform distribution of heat in a turbulent way, which equalizes the temperature difference between the floor and the ceiling of the room. The advantage of such a device is considered to be a long service life of up to 20 years.. On the shelves of stores are radiators painted in different colors, which allows you to choose the device in accordance with the design of the house. At the same time, modern products, unlike cast-iron counterparts, do not require regular restoration of the paintwork.
The only, but quite significant drawback of such a heater is its high cost. In addition, bimetallic batteries can become clogged with slag and do not tolerate a high air content in the coolant. Plus, in the place where two different metals are soldered, the heat transfer coefficient in environment premises.
Copper radiator for home heating system
An advantageous difference between a copper battery and other analogs used in a heating system is that the entire structure, starting from the radiator fins and ending with the internal circulation channels, is made of copper. Such radiators provide quite efficient heating of rooms in the house due to the maximum coefficient of thermal conductivity, which is inherent in all copper products. At the same time, in terms of heat transfer, such heating appliances 2 times superior to aluminum counterparts and 5 times steel or cast iron products.
With a minimum level of inertia, a copper battery provides the fastest heating of rooms in the house. Such radiators contain a minimum amount of coolant, which allows them to warm up in a few minutes. Due to such a small volume of water, there is no need to heat a large amount of coolant, which affects the efficiency of the autonomous heating system of a private house, which cannot be achieved if cast-iron batteries are installed.
Copper is a fairly ductile and corrosion-resistant material that does not wear out under the influence of a low-quality coolant, as is the case with an aluminum counterpart. BUT due to high efficiency at minimum temperatures a copper battery could be the best choice for any heating system. But due to the very high cost of such a product, it has not found wide distribution among consumers.
Which product to choose?
Having studied the main characteristics of most popular radiator models, you can decide which battery is best for home heating. But still, before you buy this or that model, you need to decide on some points.
Familiarizing yourself with what the various radiators are. Which better appliance to choose for heating a private house, it will not be difficult to find out. If you still have doubts, you can always get the advice of specialists who will not only help you choose the right heating battery and perform its installation.
Reliable and high-quality heating is an important component of a comfortable stay in an apartment. Radiators are an essential element of the heating system. The best of them are distinguished not only by a high level of strength, but also by an aesthetically attractive appearance. Their main task is to withstand the necessary pressure of the coolant and enable the owners to regulate the temperature in the room. The fire safety of the home also depends on their quality.
Today, the choice of models of radiators is simply huge. Often consumers have a question: which device for heating is better, more reliable? We have compiled a rating of modern and efficient devices, defining the following as selection criteria: the material from which they are made, design features, technical characteristics.
Requirements
Before choosing the best heating appliances, we will determine what requirements high-quality batteries must meet.
Pressure
The pressure declared by the manufacturer for radiator structures must be higher than the operating and test pressure in the system.
So, in old five-story buildings it is 5-8 atmospheres, in modern buildings - 12-15.
water hammer
Elements heating structure must withstand water hammer, since the system of multi-storey buildings is not immune from pressure surges.
coolant
Water used as a heat carrier in modern apartment buildings not of the best quality, so the devices should not be destroyed under its influence. It is necessary to use models coated on the inside with a special composition or chemically neutral material.
The thickness of the walls should be such that small particles of sand or pebbles do not wipe them.
Heat dissipation
The main function of radiators is heating. Therefore, those with greater heat transfer are considered to be of the highest quality.
External attractiveness
The radiator elements of the heating system must have an attractive design that will allow them to fit perfectly into the interior of the home.
Lifetime
Durability is a requirement that needs no comment.
Often messing with the installation of these large and fairly expensive heating devices is not a pleasant pleasure.
Options
The heat transfer of the entire structure, its sensitivity to the composition of the liquid in the system, weight and scope depend on the metal from which the radiator elements are made.
Dimensions and design features affect the possibility of installing batteries in a particular room. Modern heaters most often consist of several sections (the length of each is 350-500 mm). The choice of their number depends on the area of a particular room.
Operating pressure and power parameters determine the possibility of installing batteries within certain system heating.
Kinds
There are the following types of heating radiators: cast iron, aluminum, steel and bimetallic.
Aluminum Models
Aluminum heating appliances are characterized by high heat dissipation, which makes it easy to adjust the temperature. They heat the premises well (190 W of thermal power).
Light weight makes them easier to transport and install. The design of these structures is quite pleasant, to some extent elegant: they will harmoniously fit into any modern interior.
Caring for such batteries is quite simple: they are washed with a soft cloth. You don't need to paint them additionally.
But they are too susceptible to the composition of the liquid in the system: if it contains chemical impurities or it has a high acidity, then the devices will quickly become unusable.
High susceptibility to corrosion processes, fear of water hammer, inability to cope with high pressure (the average is up to 16 atmospheres) are their main disadvantages. Therefore, it is best to choose them for a private house, they are absolutely not suitable for an apartment.
Steel appliances are lightweight and thin, which facilitates their transportation and installation. They are very economical and efficient due to good heat transfer and the use of a small amount of water. These designs can be of various colors, which allows them to be used in any interior.
There are two types of steel radiators: panel and tubular. The first are characterized by a high level of heat transfer, low price. The second ones are more durable and diverse in terms of design; this is the choice of residents of expensive cottages and private houses.
Steel heating appliances are afraid of water hammer, are highly susceptible to corrosion and need a high-quality coolant. The scope of their application is buildings with autonomous heating.
Choosing steel batteries for an apartment means dooming yourself to a quick alteration of the heating system, since they are able to withstand a pressure of no more than 6-8 atmospheres.
Cast iron appliances
good old cast iron batteries, they have been used in Soviet-built houses for more than a dozen years. And due to their certain merits, these devices are still popular, especially in the homes of older people. Their advantages:
- not important chemical composition water (not afraid of acidity, various additives in the coolant);
- corrosion processes are not terrible;
- durable enough;
- much less than other models are clogged with dirt, rust, so the coolant is better passed through;
- they keep heat for a long time (the residual number of its preservation is 30%, for other devices this figure is 2 times lower), their release is much more efficient, the heat transfer area is larger;
- practically not afraid of water hammer (withstand pressure up to 9-12 atmospheres, at high values they can burst);
- modern models are made using cast iron, which allows them to fit perfectly into almost any style of interior;
- are cheaper than bimetallic heaters.
But, unfortunately, compared to radiators made from other materials, cast iron radiators are very heavy, and their transportation and installation is a laborious process. They heat up for a long time and also cool down for a long time, which makes it impossible to regulate the temperature. Old designs do not look very attractive, they often have to be painted. Decorative screens will help solve this problem.
Cast iron heating appliances are the choice of those who are conservative in their habits and do not trust everything new. This is a good option for an apartment, especially in an old house.
Modern manufacturers producing cast-iron models in retro style - Roca and Conner.
Bimetal
Our rating is headed by bimetallic radiators. They consist of a steel or copper tube and aluminum panels. Liquid (up to +130°C) under high pressure (30-50 atmospheres) passes through pipes made of steel (copper) and at the same time does not come into contact with aluminum, which, when heated, effectively heats the room.
These devices are very durable (the service life is at least 40 years), they are not afraid of water hammer, they are not subject to corrosion (treated with a primer on the inside and outside). They have a nice design. Their light weight does not cause any difficulties during transportation and installation.
Disadvantage: their cost is higher than other types of radiators. If you saw such devices at a reasonable price, do not believe it: this is a fake.
It is worth choosing the proven manufacturers of such radiator designs - Rifar (Russia), Sira or Global (Italy).
To choose these devices means to forget about problems with heating for a long time. it perfect option for an apartment.
Manufacturers
Before choosing a heater, you need to decide how much money you are willing to spend on the system as a whole. Of course, expensive doesn't always mean better. But in the case of radiator appliances, a fairly high price is almost always excellent quality.
"Global"
One of the world leaders in the manufacture of heating equipment. This Italian manufacturer specializes in the manufacture of aluminum and bimetal radiator appliances.
They are distinguished by high heat dissipation, excellent quality, increased strength, ease of installation and elegant design.
"Smart"
The Chinese company is engaged in the manufacture of bimetallic and aluminum batteries of low cost and simple design. This is the choice of those who want to save money, but not lose on quality.
"Rifar"
A domestic manufacturer of bimetallic and aluminum radiator appliances produces products with high technical specifications corresponding to the Russian operating conditions. Working pressure - up to 100 atmospheres. Service life - up to 25 years. Heat dissipation - 104-204 W.
Choosing a radiator from this company means purchasing a product of excellent quality at a reasonable price.
As you can see, of the four types of heating devices for apartment buildings, you can stop at only two: bimetallic and cast iron. They won't let you down on time. heating season and will serve their owners for a long time.
For right choice heating radiators, you need to know about their main technical parameters. Otherwise, the result may not meet expectations. There are not so many really important parameters for radiators, so even a non-professional can easily understand them.
Now people no longer need to hide or decorate radiators, because modern appliances can become a worthy decoration of any interior. Radiators that are sold today may differ in color, size, material of manufacture and general style of execution, so it will not be difficult to choose the most suitable option.
Attention! Despite the fact that we are accustomed to light-colored batteries, the heat dissipation of black devices is approximately ¼ higher due to color alone. Although when choosing a color it is better to focus on the design of the home and personal preferences.
With regards to the form, it must be streamlined. For security reasons, it is advisable to refuse sharp corners altogether, especially if children live in the house. Read the strengths and weaknesses of each before buying. existing species radiators to determine which is more suitable for a particular room. The first thing you should pay attention to is the working pressure of the devices.
Depending on the material, radiators are divided into:
The pressure mentioned above, the heat transfer coefficient, heat capacity, resistance to mechanical and chemical damage, as well as the service life depend on the material.
Radiators in the interior
Also pay attention to the method of connection to the heating line. The connection can be side, bottom and universal. It is characteristic that in modern radiators all these connection methods are provided.
Attention! The environmental friendliness of the material used in the manufacture of heating devices is also very important. There should be no formaldehyde in the internal elements, and high-quality polymer spraying on the surface is also welcome.
Now in more detail about each material.
Characteristics of cast iron radiators
Such batteries are the most common and known to every option, since they are installed in most of the typical apartments. Agree, old cast iron appliances can hardly be considered stylish and attractive. New models look better, but in terms of aesthetic indicators they are still significantly inferior to devices made of other materials.
As you know, cast iron is very heavy. Batteries made from it weigh a lot, which cannot but affect the complexity of transportation and installation.
Consider their main Benefits.
But cast iron has limitations, among which:
- significant weight;
- slow heating;
- unaesthetic.
Attention! Despite the abundance of more modern analogues, many people prefer to install cast-iron batteries, trusting what has been tested for decades.

In the manufacture of these devices using low-carbon steel. In order to protect the surface is coated with a special enamel. If steel radiators are of good quality, then they have excellent performance parameters, including:
- strength;
- reliability;
- resistance to corrosion;
- durability;
- resistance to various kinds of aggressive substances.
Such batteries can be tubular and panel.
Tubular appliances
For their assembly, high quality polymer-coated steel pipes are used. Maximum load that the instruments can handle depends solely on the thickness of the pipe walls. It is desirable that the pipes are made of stainless steel.
The service life of tubular devices significantly exceeds that of panel devices and is about 30 years. It is possible to connect in all the ways described above. The working pressure is 10-16 atmospheres, more detailed data should be clarified in the product data sheet.
Panel devices
As the name suggests, such radiators are made in the form of panels. To do this, a certain number of steel plates are connected to each other. Thanks to this assembly, a high heat capacity is achieved, while the thickness of each individual plate is negligible. Besides, panel radiators weigh a little and provide the ability to connect in all available ways.
Attention! Before buying new heaters, look at how your old ones are connected. It is desirable that new batteries are connected in the same way.
The cost of panel radiators is slightly higher than the average, the operating pressure is 10 atmospheres. According to experts, such units are best used in autonomous heating systems. As for city apartments, here the use of such batteries is unacceptable due to too high pressure in the central system.

Characteristics of aluminum radiators
Heaters made of aluminum are considered one of the most popular types of radiators. Aluminum is a light and ductile metal, therefore, batteries made from it weigh a little and are characterized by increased heat dissipation.
The devices consist of sections, each of which is a set of interconnected plates. Thanks to this, heat saving is also at a fairly high level here.
Advantages such units are as follows:
- fast heating;
At the same time, after turning off the heating, such radiators cool down quite quickly. Among the others shortcomings worth highlighting:
- instability to chemical influences (the problem can be solved by polymer spraying on the inner surface);
- low strength;
- poor quality threaded connection in the top valve to bleed air from the system.
In view of this, before buying, it is imperative to inquire about the operating pressure of the heating system. The maximum pressure of a particular product must be viewed in the data sheet, since it is different for different models.
But still, according to its characteristics, aluminum is excellent for the manufacture of radiators, and its fusibility has made it possible to significantly expand the lineup. Today you can choose exactly the battery that fits perfectly into the interior of your home.

The most optimal (and often the only) solution for providing a house with heat is an autonomous heating system that does not depend on the central gas and water supply. Therefore, all work processes related to the design, installation and maintenance of heating units and assemblies must be carried out by yourself - and pipe pipes, and install a heating boiler, and install heating radiators, choosing the best of the existing ones.
Features of autonomous heating
Both the heat in the house and the financial costs of heating and maintaining heating, heating and related appliances depend on the effective and competent calculation, selection and installation of heating radiators. Therefore, the first thing to do is to choose the type of heating, which can be air or water.
Air heating at home is heating with heaters or infrared heaters, electric fireplaces or heat from a conventional stove. Stove heating- the cheapest and easiest to implement, but its shortcomings (slow heating of the premises, low efficiency, large heat losses, dirt in the house) do not allow it to be used effectively. Electric heating by any devices is more progressive, but it is an expensive way of heating a house. Therefore, the choice of water heating in a private house will be understandable.
The advantages of autonomous heating over centralized are as follows:
- Low pressure in the pipes, which minimizes the possibility of accidents;
- The impossibility of occurrence of hydraulic shocks;
- The possibility of limiting and adjusting the temperature in the heating system;
- The ability to control the acid-base balance of the coolant, clean it from impurities and change it to a new one;
- Simple operation of the system, high efficiency and economy.
Applicable to sources of heat distribution, autonomous heating is advantageous in that heating radiators from any materials can be connected to the heating network piping - from cast iron, steel, brass, copper, aluminum, as well as bimetallic heaters. Such a variety of devices becomes possible because bleach and other reagents are not used in the coolant of an autonomous system.
Structurally, batteries or radiators are divided into tubular, panel, sectional and convector-type devices. Their advantages and disadvantages are described below.
Cast iron heating appliances
Traditional and well-known radiators are made of cast iron. Despite the wide range of products from other, more modern materials, cast iron appliances are still in sufficient demand among consumers. The popularity of cast iron radiators is explained by their advantages, including:
- The strength of cast iron, durability in operation - more than 20-30 years;
- The number of sections in the radiator, and hence its heat transfer, can be changed at your discretion;
- Good anti-corrosion and chemical resistance;
- Large inertia - cast iron heats up for a long time, and cools down just as long. Therefore, in case of emergency shutdown of autonomous heating, such radiators are preferable;
The strength of cast iron radiators is their advantage and disadvantage, which is expressed in the large weight of the products. Another drawback is that it will not work to quickly change the temperature of the battery. Outdated appearance, rough surface and the same design do not attract lovers of exclusivity and originality. But for them, the industry produces steel, aluminum and bimetallic devices that have a well-thought-out diverse design and high efficiency.
Steel batteries and radiators
Steel radiators are produced in tubular and panel type. The panel construction consists of two figured plates up to 2 mm thick, which are connected in one housing using spot welding. Having a low inertia, steel batteries are capable of intense heat radiation, and their modern design and original forms of execution do not increase the cost of devices. But there are also disadvantages: radiators quickly rust with poor-quality paintwork, the metal reacts with reagents added to the coolant, a fixed number of sections in one device.
Tubular type radiators are distinguished by the fact that they have an individual original design; you can also choose various forms of devices. Tubular products are produced in which steel is coated from the inside with special polymer-based compounds, which increases their anti-corrosion qualities.
Aluminum radiators - advantages and disadvantages
Autonomous heating in country house is a structure of pipes and radiators with water as a heat carrier, and such a system is called water heating. For a private house with such heating, the most preferred type of heating devices will be aluminum radiators with the following performance advantages:
- The small mass of the product, which allows you to mount devices even on drywall;
- Aesthetics and versatility of design - aluminum radiator will fit into any room design, from retro and classic to hi-tech or modern;
- High efficiency and heat transfer;
- Temperature control by means of special valves mounted on the radiator housings.
Disadvantages, the knowledge of which will help extend the life of the aluminum case:
- Additives that destroy the body must not be added to the coolant operating in aluminum batteries. You should also filter water or other coolant from solid particles;
- The threads on aluminum are quite fragile, so you should carefully assemble the sections and screw in the taps and fittings, as well as watch for possible leaks.
Characteristics of bimetallic radiators
These are batteries, the case of which is made of an alloy of iron and aluminum. Structurally, it looks like this: the body of the device is sheathed with aluminum, and the coolant, when passing between the steel elements, does not come into contact with aluminum. A bimetallic heating radiator can also work in an aggressive environment of a centralized heating system due to its main advantages:
- They withstand pressure up to 35 atm;
- Have less weight due to aluminum coating;
- high efficiency and low inertia.
There is only one drawback - bimetal products are more expensive than others, not counting copper or brass radiators.
Choosing a radiator according to its power
In order not to make a mistake in choosing and choose the right home radiator for your home, you should not immediately focus on its design - this is not the main thing for heating a house. The main thing is its power, and this value is indicated in the product data sheet. Knowing the volume of the room to be heated, it is easy to calculate the required radiator power. For example, for full heating of 1 m 2 in a room with three-meter ceilings and one window, ≈ 100 W will be consumed. Therefore, it is necessary to multiply the total area of \u200b\u200bthe room by 100 W. For more accurate calculations, take into account the following corrections:
- If the room has one window and 2 outer walls, then the result must be increased by 20%;
- If the room has 2 windows and 2 outer walls, then the result should be increased by 25-30%;
- If the window in the room faces north, then the result should be increased by 10%.
After such calculations, you can more accurately select a radiator. And it doesn’t matter at all which radiators you decide to choose, which ones are better for a private house and more efficient if they are installed incorrectly. In the best case, improperly located and connected radiators will serve as an interior decoration, in the worst case, they will interfere and clutter up the premises, but not heat them.
Let's look at where to mount radiators - this information will definitely be useful to you when you create a heating scheme. So, batteries should be placed under light openings - windows. This place always has the most heat loss, even if you have modern double-glazed windows installed. A radiator placed under the window will warm the air around it. After that, the heated air rises and creates a curtain in front of the window, preventing the penetration of cold into the room.
When choosing which heating radiators are best purchased for a private house, do not forget about the importance of the length of the appliances - it must correspond to the width of the window opening. In extreme cases, the length should be at least 50% of the width of the window. In a corner room, it is worth placing 1-2 additional devices along the outer walls exposed to cold air. If you are going to install heating risers, mount them in the corners, which will ensure their heating and avoid the possibility of blackening of the walls and the appearance of mold in them.
And do not forget that access to the batteries must be open. Many owners of private houses cover heating radiators with drywall sheets, which is undesirable - this will complicate the process of cleaning and repairing appliances if necessary. In addition, the use of such a fence will lead to a revision of previously performed power calculations.
We told you how and which radiators are best to choose for installation in a private house. Now you know that when buying appliances, you need to consider the quality of the water in the pipes, the power of the devices, their appearance, and even the ability to install on fragile partitions, if necessary.
Heating radiators - which are better for a private house updated: February 16, 2017 by: crunch0
Choosing a heating radiator for your home is a task that must be approached responsibly. The rate of space heating and its efficiency will depend on the type of battery and some other factors.
In this article, we will consider the main types of heating radiators for a private house and apartment, the advantages and disadvantages of different types of batteries, and also give some tips on choosing them.
Classes of heating radiators
There are 4 classes of heating devices:
- Sectional;
- lamellar;
- tubular;
- Panel.
Sectional type radiators are known to everyone. They are made of cast iron, aluminum, steel. There are models for the production of which two materials are used (usually steel and aluminum). Such batteries are called bimetallic. Sectional radiators are assembled from separate sections (sections), resulting in a heater with required power given to the external environment during operation.

Plate heaters are called so because they are made of several plates mounted on curved or straight pipes. The pipes, in turn, circulate water. Another name for plate heating devices is convectors. They can be electrical or non-electric.

Tubular radiators are made of several tubes interconnected by collectors. They look pretty original. Such radiators are often found in apartments where the interior is made by professional designers. Pipes can be made in any size and shape, for example, in the form of a specific shape.

Panel heating radiators consist of panels that receive heat from the coolant circulating in the space between them through channels formed by stamping. There are models with one, two and three panels.
Let us consider in more detail each of the types of heating radiators.
Cast iron sectional radiators
The first development of cast iron batteries was carried out almost 150 years ago by our compatriot. A few years later, the Americans received a patent and finalized the design. Radiators gained popularity after the advent of the central heating system, and their mass production was adjusted during the industrial revolution.
The batteries that were used in the USSR and now remain in many homes have the MS 140 brand. The value "140" is the power given by one section. The operating and test pressure of the battery is 9 and 18 atmospheres, respectively. The number of sections is from 4 to 10.

The advantages and disadvantages of this type of battery are approximately the same.
Advantages:
- Long service life (more than 50 years);
- Affordable price;
- Resistance to mechanical damage;
- Corrosion resistance;
- High abrasive wear. Pebbles and sand in the water do not cause much harm to the battery from the inside;
- Heating efficiency at the maximum number of sections.
Flaws:
- Great weight and bulkiness;
- Possibility of depressurization of joints;
- Accumulation of rust inside during long-term operation;
- Unpresentable appearance;
- Difficulty in embedding radiators in autonomous heating systems, the impossibility of saving on the coolant;
- Difficulty cleaning.
Bimetallic radiators
Bimetallic radiators are most often made of aluminum and steel. The latter is used to make horizontal and vertical tubes, soldered together, and the outer case is made of aluminum. The coolant flows through the pipes.
Typical dimensions of tubular radiators
The above calculations are approximate. It is difficult to create ideally sealed conditions in a room. Heat can escape through the floor, walls, windows. It is necessary to take into account all the nuances, up to what material the house is made of, whether the room is heated under and above you, etc. It is possible instead of 41 watts on cubic meter ask for a power of 60-70 watts, although it is better to carry out competent insulation so as not to spend money on heating the street. But to achieve overheating is also impossible, it will negatively affect your well-being.
Unit dimensions
Dimensions partially depend on the power of the radiator. In this case, the location of the device must be taken into account. Most often, batteries are mounted under the windowsill. Measure in advance the distances (height, width) in the place where the radiator will be installed, calculate the power needed to heat the apartment and select a heater according to these parameters.
Design
Taste setting. Here the consumer is not limited by anything and is free to choose the unit that will appeal to him.
Manufacturers
Italian manufacturers are considered the best. Good products are produced by German, Austrian, Finnish craftsmen. Manufacturers of the CIS countries are not much inferior to them.
Measure all the features of different types of radiators, calculate and make the right choice.
