Heating system radiators of a private house. What heating radiators are best for home

The most convenient (and sometimes the only possible) option for arranging heating in a private house is to use an autonomous system that does not depend on centralized water supply sources. Accordingly, most of the work related to its organization, installation and maintenance has to be solved independently. That is, the question: “what better battery heating for a private house? " is essential and relevant for a huge number of homeowners.

From how efficiently and competently the calculation will be made, selection and installation heating appliances, depends not only on the comfort of living in it in winter period but also the amount of material costs associated with heating and maintaining the house. Therefore, first you need to choose the type of heating system that will be installed in it. She may be:

Air.
Water.

In the first case, the rooms are heated by stove heaters or special electrical devices , which include infrared heaters.

Stove heating is the cheapest and in a simple way heating, however, while it has many disadvantages, such as:

Long warm-up period.
Low heat transfer coefficient compared to other energy sources.
A high percentage of heat loss (most of the heat with such heating goes into the chimney).

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

A more popular and common option for heating a private house is water-type heating systems, in which the heating of the premises is carried out by heating the water moving along the radiators and pipes.

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

Low network pressure;
Lack of likelihood of occurrence;
Limited and adjustable coolant temperature;
The ability to control the acid-base balance of the coolant.

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

Types of materials and design features

Answering the question of which radiators to choose for heating a private house, you need to determine for yourself what materials they will be made of. They can be made from the following types of metals:

Cast iron

Radiators from it can withstand temperatures up to +150 degrees and pressures up to 6-9 atm. Thermal power their sections are 80-160 watts. Period of use: up to 50 years.

Pros:

- durability, strength and reliability;

- immunity to the quality of the coolant;

- the possibility of combining a different number of sections;

- corrosion resistance.

Disadvantages:

- heavy weight and rough appearance. But, at present, models with an original design are also produced that can decorate any interior.

- high inertia, which will be a disadvantage for an autonomous one.

Become.

Some consumers, choosing which radiators are better for heating a private house, give an unequivocal answer to this question: "Only steel". And there is a completely objective explanation for this answer. Take at least a list of their advantages and benefits in comparison with other types of heating devices.

These include:

- excellent heat dissipation;

- low inertia;

- low price;

- light weight and neat dimensions.

Disadvantages:

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

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

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

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

Aluminum

Best suited for heating a private house for several reasons:

- they have modern design;

- have high thermal power and inertia;

- easy to install.

They can be operated at a working pressure of 10-25 atm. and a limiting temperature of up to +110 degrees. The section power for such heating devices reaches 200 watts.

Please note that thermal power is not only their indisputable advantage, but also their "weak point". The fact is that at a high heating rate, warm air rushes up quickly, which can lead to the fact that the temperature in the upper part of the room and at the floor will be very different. Therefore, before choosing a radiator for a private house made of aluminum, it is necessary to calculate what area to be heated, taking into account all the features of the room. Otherwise, the floor may remain cold when used.

Bimetal

In this case, we are talking about batteries made of two metals. Most often they have a steel core covered with aluminum. Devices of this type have large quantity positive characteristics:

- have increased resistance to water hammer;

- have increased heat transfer and chemical resistance;

- have an attractive design and light weight, etc.

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

However, due to their high cost, they are not very well suited for the arrangement of a private house, in which the average indicator in the heating system is 2-3 atm., And there are also no water shocks and a high PH level of the coolant.

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

They can be:

Tubular;

They are structures consisting of several tubes connected by collectors. They have an original design, a wide range of sizes and shapes.

Sectional;

They are assembled from separate elements (sections). Available in a variety of materials including cast iron, steel and aluminum.

Panel;

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

Important: Tubular and panel radiators are only available in steel.

Convection.

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

Convectors for hot water heating belong to a separate class of heating devices, which are based on a different principle of operation (they are not radiators)

After choosing radiators, they need to be correctly installed. Various are described in a separate article on the site.

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

Many experts, before choosing heating radiators for a private house, recommend making a calculation with which you can choose the type of battery that is optimal for each specific case. In this case, the amount of energy required to heat 1 square meter of living space is taken as a basis. This figure, on average, is from 95 to 125 watts.

Also, the calculation takes into account the parameters of the room. It is believed that in a room with a ceiling height of up to 3 m, one window and a door, the temperature of the coolant in the system for its normal heating should be about 70 degrees. When these parameters are “shifted” to either side, appropriate amendments must be made to the calculation.

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

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 corner-type rooms with several window openings the total heat output of the radiators installed there increases by 1.5 times.

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

Important: Regardless of the design and principle of operation of the system, it makes no sense to install in the house heating radiators, the number of sections in which exceeds 10 pieces, since the energy output from the "extra" ribs will be very low.

Comparison of batteries for a private house

In order to figure out which radiators are better to choose for heating a private house, you can make a small comparative analysis, assessing the advantages and problem areas of each type:

Let's consider the technical parameters separately. heating batteries different types and the possibility of their installation in a private house:

Variety	Working pressure indicator, atm.	Compatible with the heating system of a private house	The 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 (European model)
Cast iron	6-9	Yes	Low (excluding original decorative models)

Thus, to the question, what better radiators heating for country house, we can answer that, based on material, practical considerations and ease of installation, the choice should be made in favor of batteries made of aluminum or steel, which have many advantages and have a low price.
Also, to figure out which heating batteries are best for you in a private house, video will help.

Radiators and radiators - which ones are better for a private house? This question is asked by every owner of a country house who decides to provide his home with an autonomous heating system. Today we will consider which radiators to choose for a summer residence.

For installation in an apartment where a centralized heating system is installed, not all radiators can be used. But for a country house, all types of devices are suitable. Indeed, in the water that passes through pipes in private houses, most often there are no impurities with chlorine and alkali. Various materials are used for the manufacture of radiators:

cast iron;
metal (steel);
aluminum;
bimetal.

Types of heating devices for a country house

And according to their design, aluminum and other devices are divided into sectional, tubular, panel and convector. Let's study each of the types of heating radiators for installation in a private house - knowledge about the advantages, disadvantages and features of operation will help to make right choice.

The simplest type of radiators is cast iron. These products are still popular in the market despite their more modern counterparts. It is quite simple to explain such popularity - cast iron products have a lot of advantages, including:

time-tested strength and durability - can serve for two decades or more;
the ability to assemble a radiator from a different number of sections;
rust resistance;
low level of heat transfer;
the material is not afraid of chemical attack.

Cast iron radiators

Durability is due to the fact that cast iron batteries are equipped with very thick walls. But this is precisely the main disadvantage of the products - too much weight due to the severity of the materials used for the production. Low thermal conductivity is considered a plus and a minus at the same time. The main advantage is that the batteries, although they warm up slowly, also cool down slowly - if the heating is turned off, the radiators will remain warm for some time. But such radiators will not be able to quickly regulate the temperature with the help of regulators.

Another drawback of cast iron batteries is their unpresentability. True, in the modern market you can find models with an exclusive design, but their cost will be much higher than the price of ordinary radiators.

Steel batteries are produced in two types: they can be tubular and panel. Panel panels are two connected plates with a thickness of up to 2 mm. Their advantages include low inertia, radiation of a large amount of heat, a modern stylish look, the ability to manufacture products. different forms, low cost and resistance to double vision inside the heating system. but steel types radiators have such disadvantages as:

high risk of rust;
restrictions on use in heating systems, the coolant in which contains various alkali reagents;
impossibility to choose the number of sections - steel radiators are produced already assembled ready-made panels.

Steel battery

One of the varieties of steel radiators is tubular models. Their main advantage is their interesting design and the ability to choose the appropriate shape. You can buy a product with an internal coating of steel with special polymer compounds, which will reduce the risk of rust.

Autonomous types of heating in private houses are most often made in the form of a system of pipes and radiators, where hot water acts as a heat carrier. Such systems are called. If you have just such a system installed at home, it is better to stay on aluminum radiators for a private house. They have such advantages as:

light weight, which will allow you to install radiators even on fragile plasterboard walls;
aesthetic appearance;
high level of heat transfer;
the ability to regulate the temperature with special taps.

Faucet for regulating the temperature of an aluminum radiator

However, aluminum products have some disadvantages that it is advisable to know about in advance. So, for example, the coolant in such radiators must be free of chemical additives and solid particles that can destroy the material. Moreover, aluminum radiators are known to have threaded connections not of the highest quality, which increases the risk of leaks.

Today on sale you can find a new type of radiators - bimetallic. These batteries are made of an alloy of aluminum and steel, which makes them quite practical and reliable. The design of the device is presented in the form of a steel core, which is covered with aluminum. As a result, the coolant passing through the steel elements does not harm the aluminum. Thanks to this design, such radiators can also be used in apartments with a centralized heating system. The main advantages include:

the ability to withstand pressure surges in pipes (up to 35 atmospheres);
low weight due to the use of aluminum;
high level of heat transfer.

Bimetal radiator

If we talk about the minuses, then it is one - a fairly high price. Such radiators cost more than aluminum, steel and cast iron, which slows down their widespread use a little.

How to choose the right heating radiators for a private house? Here, not only the appearance of the products is important, but also the power - when buying a device, you need to find out how much power is needed to heat the system. This is not as difficult as it might seem at first. So, heating one square meter in a room with a ceiling height of three meters and one window requires about 100 watts. Then simply multiply the area of the room by 100 W. And to make the calculations even more accurate, do not forget:

if the room has one window and two external walls, add about 20% more to the calculated power;
if there are two windows and two outer wall- add about 25-30%;
when the window faces the northern part, it is worth adding at least 10% to the calculations.

By doing these calculations, you can more accurately choose the right radiator for your home. And the power of devices can always be seen in the documents - the "passport" of the device. By the way, it doesn't matter at all what kind of radiators you decide to choose for installation in a private house, if you install them incorrectly, they will decorate your home, but will not provide the necessary heat to heat the room.

The choice of radiators for a country house

Let's take a look at where to mount the radiators - this information will definitely be useful to you when you create. So, batteries should be placed under light openings - windows. This place always has the most heat losses, 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 up 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 devices - it should correspond to the width of the window opening. In extreme cases, the length should be at least 50% of the window width. IN 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 warming up and avoid the likelihood of blackening of the walls and the appearance of mold in them.

And do not forget that access to batteries must be open. Many owners of private houses cover heating radiators with sheets of drywall, which is undesirable - this will complicate the process of cleaning and repairing devices, if necessary. In addition, the use of such a fence will lead to a revision of earlier calculations for capacity.

We told you how and which radiators are best to choose for installation in a private house. Now you know that when buying devices, you need to take into account 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.

What heating radiators are best for home

Living outside the city has many advantages, but it takes a lot of effort to ensure a comfortable living environment. One of the most important points is the selection and installation of the heating system. She must not only work efficiently, but also save the family budget. And for this, you should purchase the most optimal heating battery option.

What factors should be considered when choosing a radiator

In any hardware store, a huge range of heating equipment is presented. For this reason, before going to the building supermarket, determine the following parameters, which will determine the amount of heat required for the room:

Heat losses of the building (taken into account: decomposition of the building material (refers to wood), ceiling height, number of windows and doors, glass thickness, etc.).
Necessary temperature regime.
The thermal power of the device is determined by the following formula: S * h * 41: 42, where S is the area of the room; h is the height of the room; 41 - minimum capacity per 1 cubic meter S; 42 - nominal thermal conductivity of one section according to the passport.
The heating radiator, as a rule, is located under the window, therefore its maximum size is determined by the following measurements (in cm): from the floor 7-12, from the walls - 3-5, to the windowsill - 10-15.

It is also important to note for yourself:

weight (the complexity of installation depends on it);
appearance (affects the aesthetics of the interior);
value for money (is the determining factor).

Heating batteries which are better: types and characteristics

All heating radiators differ in design and the class of material used.

According to the shape and texture, there are many options, it all depends on your taste preferences. Whether they will be wide or narrow, plain or colored, backlit or with designer painting - you decide. The main thing is that they function according to the declared characteristics.

With regard to the method of operation and the type of material used, batteries are divided into 4 classes:

cast iron;
aluminum;
steel;
bimetallic.

To understand which heating radiators to choose for a private house, you need to consider their options in more detail.

Cast iron

For over 100 years, cast iron heating technology has been very popular. This is justified by the number positive qualities cast iron batteries:

Significant heat transfer (they heat up to 130 degrees and remain hot for 5-6 hours).
Durability (the service life can be 50 years or more).
High level of strength (external mechanical damage, as well as high pressure inside the system will not damage the structure).
Resistant to corrosion in case of sudden temperature changes and constant influence of condensation.
Unpretentiousness to the quality of the coolant (filters are not required at the entrance to the heating system).
Availability (low cost).

However, due to their shortcomings, such systems are gradually being replaced by other, more advanced ones.

Cast iron heating radiators are larger than other models, which complicates their transportation, installation and maintenance. They also have other disadvantages in operation:

Low thermal conductivity. For good heat transfer, it is necessary that the temperature of the coolant be 70-80 degrees. (Justified by the massiveness and porous surface of the metal).
Require systematic care (periodic painting and cleaning).
Bulky (take up a lot of space). They do not fit into the interior of the home, although original fences or partitions can be used to improve their appearance. There are also special design solutions from French and German manufacturers that will look good with a certain interior style. Such batteries look very nice, but their cost is also high.
Require good fastening against the wall due to its heavy weight.

Cast iron batteries are produced in China (KONNER and Tokio) and Russia (MS-140).

Aluminum

Aluminum is distinguished by significant thermal conductivity, therefore, products made from it are very productive.

Benefits:

Ease.
Compactness.
Powerful working pressure (12-18 atmospheres).
Ease of operation (sections are easily removed / installed).
Significant heat dissipation due to the shape of the sections.
Increased heat transfer. Due to the volumetric cross-sectional area of the intercollector tubes, the heat agent circulates faster and gives off heat to the metal.
Variety of sizes.
Acceptable price.
Attractive appearance.

Along with the advantages of aluminum radiators, there are also disadvantages:

Increased susceptibility to pressure drop and the composition of the heating agent (high-quality filtration and pressure gauges are required to control the pressure during filling).
It is not resistant to chemical factors (corrosion), so pay attention to the presence of a protective polymer film (coating) on the surface of the product.
Rapid wear and tear (they function for 10-15 years).

According to the layout of the sections, there are three categories of aluminum radiators: solid, assembled sectional and combined. But which heating radiator is better:

One-piece is distinguished by its strength and plasticity;
Assembled sectional panels (type-setting) make it possible to replace failed plates;
Combined - combines both functions, but also costs more. Similar systems are manufactured by the following firms: Condor, RIFAR, Global, Ferroli.

Steel

They are divided into three subgroups according to the structure of the internal system.

Panel

Rectangular radiators, consisting of two welded panels with grooves-recesses, dining channels in which the carrier circulates. Such a heating battery is quite lightweight and compact, and allows it to reach the required temperature in a short period of time. Another name is convectors, since heat is supplied by convection (75%).

Their disadvantages include:

low working pressure;
shock sensitivity;
susceptibility to corrosion.

Manufacturers produce radiators with top and bottom piping, which allows heating in the floor. Manufacturing companies: Buderus, Lidea, Corado.

Steel sectional

They are similar to cast iron, but have significant positive differences.

Strength provided by welded joints.
Internal pressure of 16 atmospheres.
Durability (up to half a century).

Although they are not available to a wide range of consumers, due to their considerable cost.

Tubular

It is worth noting their high price right away, because they stand out for their ideal design and effective functionality. Tubular radiators make it possible to implement your own design ideas in a heated room. Produced by foreign companies: Delonghi, Zehnder, Arbonia.

Bimetallic

According to the external features, they do not differ in any way from the aluminum ones. Their inner part is made of high quality steel or copper. This significantly increases their safety, service life and reliability.

Despite their cost, they have long and confidently been the leader in the heating technology market. Therefore, it is safe to say: bimetallic radiators heating which will last better and longer in your cottage - compensate for the money costs by the quality of work.

Based on the above, it can be noted that both subspecies are suitable for use in private homes. Now let's carry out a comparative analysis for a number of features and find out which of them should still be given preference.

Heat volume

An aluminum heating radiator (its section) provides 200 watts of energy. One part is released as radiation, and the other is converted. Within 10 minutes after switching on, the air in the room begins to warm up, which makes it possible to save a lot.

In bimetallic ones, heat transfer occurs differently: the steel core slightly slows down its propagation. In principle, this figure may differ depending on the model. Otherwise, there are no significant differences.

Heat carrier temperature

Bimetal is able to maintain water temperatures up to 130 degrees, but aluminum only up to 110.

Life time

Bimetallic radiators combine the properties of two metals, therefore, their service life is longer (15-20 years), compared to their competitors (about 10 years).

Installation

Both radiators are lightweight steel mount installed on screws and ordinary plastic dowels. With the help of a set of keys and shaped tools, components are installed and replaced.

Aluminum or bimetallic batteries which are better in terms of service life

In our country, the composition of water includes many chemical impurities, and since aluminum tends to react with various substances, this is extremely undesirable for it, since rust will simply eat its walls. For normal activity, the pH should not exceed 8 units.

Bimetallic radiators are better protected by a special coating against the effects of an overly active heat agent - they are not so susceptible to rust. However, there are cases of hydrogen entering the liquid, then the components begin to rot very rapidly.

Manufacturing companies do their best to improve their products. And answering the question which bimetallic radiators are better, it is necessary to highlight the brands Polywarm, Teplopribor, Royal Thermo Vittoria, Sira. One of the most renowned manufacturers is from Kermi, Germany.

Outcome

The warmth in the house creates a cozy atmosphere. To always feel comfortable in your home, you need to correctly calculate the number of radiators and choose them.

Buying heaters for a private house according to the recommendations of experts, you can easily choose exactly those heating batteries which are best suited for you and satisfy your individual needs.

One of the main components of a home heating system is a radiator - a battery for heating, as we used to call it. Consider radiators for heating - which ones are better for a private house, what are they made of?

Living in a private house has many advantages, along with this, a lot of worries and efforts fall on our shoulders, we strive to ensure that everything is equipped competently and of high quality. An autonomous heating system in a private house is one of the main aspects responsible for comfortable accommodation... You will not be dependent on a centralized system, you can always heat your home, regardless of the heating turn-on schedule (as is the case in urban residential buildings). Your own heating system can be calculated and assembled at will and, of course, each of us strives for everything to be done reliably in this matter, for many years.

The correct choice of equipment is important both for the budget and for the subsequent comfortable operation. Today the construction market offers a wide range of modern heating equipment. When choosing radiators, you should consider options with an advantageous price ratio and a maximum heat transfer rate. If we judge objectively, then any batteries can be suitable for a home heating system, but there are still certain nuances.

Heating radiators - which are better

What are modern batteries like? If we consider the so-called steel options, then there are panel or tubular models. Despite the fact that they are considered the most budgetary, they are characterized by good heat transfer and relative compactness. Panel models consist of two metal plates connected by welding. Due to their area, such radiators are capable of producing a lot of heat.

Panel version, photo:

Tubular options will come out to you a little more expensive than panel counterparts, they have a completely laconic appearance, somewhat reminiscent of old cast-iron batteries. They come in a variety of designs, shapes and sizes.

Tubular batteries, photo:

Some models of steel radiators have an internal polymer coating that prevents corrosive processes.

Benefits of steel structures:

reasonable price along with high efficiency;
do not oxidize from poor quality water;
long service life
light weight
convenient sizes.

The disadvantages include:

rough appearance (panel version);
require flushing every 3-4 years (to avoid slagging of the system);
need constant filling with water (in order to avoid activation of corrosion processes).

Aluminum radiators

Due to their low weight, they can be mounted even on thin walls and partitions. They have aesthetic modern design and high heat dissipation. Cons - short operational life (15-17 years), susceptibility to corrosion, leaks may form at the joints of the sections. According to the specifics of the connection of sections, aluminum batteries can be assembled, solid and combined. One-piece models are more reliable, they do not have connections through which water can seep over time. Arranged radiators allow replacing worn-out sections. Combined models possess the qualities of the first two analogs.

Aluminum batteries, photo:

Bimetallic heating radiators

They are considered the most "advanced" and improved. These batteries combine the qualities different types metal - heat transfer of aluminum, resistance to rust (inside are made of copper or high quality steel). A bimetallic radiator has a layer of anti-corrosion coating both inside and outside (in more expensive models). The declared service life of such batteries is 40 years. They have a higher price compared to all other types of radiators, however, the money costs are offset by quality and high performance.

Bimetallic version, photo:

Cast iron radiators

The most durable, reliable and time-tested. The first cast iron batteries appeared over 100 years ago. Their appearance is known to everyone, despite the fact that the service life of this radiator is 50 years, in many houses they can be found even now. Such batteries cool slowly, retain heat longer (compared to, for example, an aluminum analogue) - this factor allows you to reduce gas costs.

Examples of modern cast iron batteries, photo:

The cast iron heating radiator is highly resistant to corrosion processes and has a large wall thickness. Despite the fact that the internal volume of the sections is quite large and requires a lot of water for filling, this feature allows you to provide heat to a large area of the room. These batteries are heavy and require appropriate heavy duty mounting brackets. Over the years, their appearance has not changed much, but today on sale you can find refined versions of modern cast iron radiators... The outer surface of such structures has an improved design, which is suitable for a certain style in the interior (classic, retro).

For the price, these radiators are more expensive than aluminum models, but cheaper than bimetallic ones.

Which heating radiators are good

After conducting a small comparative analysis of the proposed models for a private house, we can draw the following conclusions:

If you want a reliable economy option then choose a high quality aluminum battery from a reputable manufacturer. They are aesthetic, lightweight, and will work perfectly in a home autonomous heating system.
If the question of price does not bother you, then choose sectional bimetallic radiators - they are good in all aspects.
Reliable, solid cast iron options will keep your home warm for a long time, and they are also very convenient for drying things in the cold season.

To the question - heating radiators, which are better for a private house, the answer will be this: in each individual case, you need to calculate your capabilities and take into account the requirements of your individual system heating. It is necessary not only to calculate the correct number of radiators, but also to produce high-quality thermal insulation of the whole house. If the dwelling is poorly insulated, not a single radiator will help in the fight against the cold.
