Heating radiators for home which are the best. What heating radiators are best for a private house. Their advantages include

Premises. Water or other coolant passes through the battery, heats it, and the plates or pipes, according to the principle of convection and heat exchange, heat the room. The thermal conductivity and quality of the product are directly influenced by their design features. Some of the radiators cannot withstand operation at all in a private house, while others have been successfully used for 50 years or more. So, let's figure out which heating batteries for a private house are the best.

Cast iron batteries

Corrosion-resistant, durable, heats up for a long time, but also cools down for a long time, due to which the room remains warm, even when the system is turned off. But, and the possibility of a smooth one is completely excluded. Cast iron is heavy, but it has a large flow area, that is, deposits can form inside, and this will not affect the throughput and heating of the battery in any way.

Cast iron batteries made by art casting look very good in country houses, but standard budget options need to be tinted, which spoils the surroundings.

Aluminum batteries

The metal is very susceptible to corrosion, so some manufacturers protect the core with a polymer layer. Such radiators are made by two methods: casting or extrusion (extrusion). The advantages of aluminum are low cost, light weight and excellent heat dissipation. Among the disadvantages: low operating pressures and high susceptibility to corrosive processes.

Bimetallic batteries

positioned as the highest quality since the outer part is made of lightweight aluminum, which has excellent heat dissipation, and all the inner tubes and cores are made of steel. Steel is durable, does not corrode and withstands a pressure of 25-30 atmospheres at a nominal load in the heating system of 5-7 atmospheres. You can choose the option with a copper core in case antifreeze is added to the coolant, which aggressively affects the steel base.

The presence of alkalis in the water and the different expansion of steel and aluminum leads to a rapid destruction of the core.

Sections or panels: the main differences

By type of construction, radiators are divided into sectional and panel ones.

Sectional

Prefabricated structure to be connected to the manifold. Easy to operate and repair, weighs little. The number of sections can be changed even after the radiator has been installed.

Each unit is removed and cleaned if dirt appears. Thanks to the use of new production techniques and high-quality materials, sectional batteries can withstand high pressure and serve for 20-50 years. They differ from monoblock and panel versions by the possibility of simple replacement of parts and setting the required power level by changing the number of elements.

Panel

Panel radiators consist of an upper grille and fins for convection, heating panels, channels for the coolant and connection pipes. They fit much better because consume little energy, give off heat well, are environmentally friendly, cost little. Cons: water shocks are dangerous for them and they corrode during the time when water is drained from the pipes.

There are also tubular and plate radiators. Tubular models are two horizontal collectors connected by a curved steel pipe. Plate batteries are a metal tube on which thin plates are worn. Heat transfer depends on their area and quantity.

Advertising and a list of technical parameters say little about the suitability or unsuitability of a particular model for a particular case. To choose the best quality option, you need to consider:

The maximum pressure in and this indicator for radiators. The upper pressure limit for different models and manufacturers varies from 16 to 100 bar. Even if the heating system works with lower values, the margin will speak of the reliability of the product and the ability to withstand a water hammer;
Heat carrier and temperatures to which it will be heated;

Diameter of pipes and sections for connecting a radiator;
Heating system type (one or two-pipe);
Warranty and service life.

If the choice stops on sectional models, you need to take into account the height of the ceiling and the area of the room in order to choose the optimal number of sections. Heat transfer depends on both the material and the width of the product, so you need to pay attention to this point as well.

The required power is calculated by the formula: It remains to divide the resulting figure by the heat transfer rates from the selected manufacturer and determine the required number of sections.

Long-term and safe operation depends on the sum of all the details.

So, radiators for a closed autonomous heating system must withstand high temperatures and pressures and be located far from easily flammable interior elements and wood.

Manufacturers: prices, characteristics, reviews

Each manufacturer is trying not easy to make high-quality heating radiators, but also to add some unique features. Thus, the Italian brand Sira was the first to launch bimetallic batteries. Syrah sections are available in lengths of 300, 500 or 800 mm. The cost of each ranges from 700 to 1200 rubles.

In terms of quality, the Russian Rifar also belongs to the premium class, which has both aluminum and bimetallic models, at a price of 450-900 rubles. per section (depends on thickness, height, model).

Radiators from GLOBAL and SMART have been conscientiously produced. Beautiful and durable cast iron radiators are produced by Demir Dokum, Retrostyle and M300. The exact price is determined by the design and equipment. Demir has the most affordable option - 4 sections for 18 thousand rubles.

Cast iron

Consumer reviews

Michael:“Cast iron radiators for a private house are the best! I have high ceilings in my dacha, I need good heat dissipation. Only cast iron radiators can be heated. There are no complaints for 10 years of service ”.
Svetlana:“We chose cast iron for the house because of the affordable price. It is necessary to tint periodically and plaque forms inside - the quality of the water affects. But overall, everything works fine. "

Aluminum

Buyers' opinion

Natalia: « I bought CALIDOR Super aluminum batteries 5 years ago (there was not enough money for more). In winter, you can sleep with the window open. There are no leaks. "
Bogdan:“I've heard a lot about leaks and wear out quickly (only 10-year warranty). But I consulted with the experts and installed the aluminum batteries, and I installed it myself. They serve well, and they didn't hit the wallet. "

I am often asked the question: which heating radiator is better for a private house? And for an apartment? And why? I decided to give answers in the form of an article, surely someone is now looking for answers to these questions.

By design, radiators are divided into:

sectional and block made of cast iron, aluminum, steel, bimetallic;
columnar made of steel, aluminum or other non-ferrous metals;
panel made of steel.

Design water heating radiators

Nowadays, design radiators are popular, I have come across really beautiful radiators. A good collection of radiators from the Russian manufacturer Varmann.

Radiator design Abstract

Another beautiful radiator from Varmann.

Within the framework of this article, I will not consider in detail the design of radiators. Just know that such radiators not only exist, but are also gaining popularity. At least, I meet with such radiators more and more often.

Sectional radiator types

Sectional radiators are available in aluminum, cast iron, bimetallic and steel.

Aluminum sectional radiators consist of sections made entirely of aluminum. The main advantage is low cost.

Cast-iron radiators are not only Soviet-made, and everyone is familiar with the MS-140, but also quite nice. Cast iron radiators KONNER look good, we have installed these radiators several times with.

Cast iron radiators work well in gravity (gravitational) heating systems, if the heat source is a solid fuel boiler, then such radiators protect the boiler from boiling.

Bimetallic radiators are made of aluminum, but the inner tube part is made of stainless steel. The main advantage is high pressure resistance.

Steel tubular radiators are not common to me. I would attribute them to the design of radiators, not every our customer agrees to install them.

Types of steel panel radiators

Each steel panel radiator has a type designation, for example: 22 500 * 1000. The last digits 500 and 1000 mean the height and width radiator in millimeters.

Type 22 is probably the most common type of radiator. There are several types of finning:

10 Type - smooth panel

11 Type - ribbed panel

20 Type - two smooth panels

Type 21 - one smooth panel and one ribbed panel

22 Type - two panels with ribbing

30 Type - three smooth panels

33 Type - three panels with ribbing

Different types of radiators are made in order to have different power with the same overall dimensions.

Panel radiators can be of different heights, the most common are 300 and 500 mm. The most common type is 22.

Is an aluminum or bimetallic radiator better?

The bimetal radiator is made of two metals: aluminum and stainless steel. The stainless steel core is harder and stronger than aluminum + no chemical reaction with other metals.

If you have aluminum radiators tied with copper pipes, expect trouble, the radiators will clog over time and stop heating. Even during a chemical reaction, hydrogen is released, it will not rupture the radiator, but the heat exchanger on the boiler is easy.

Attention!
Copper reacts to aluminum and zinc. It is better not to combine these metals in heating systems.
If you want details with tedious formulas, read the article in the journal S.O.K.

Cheap sectional radiators

I strongly advise against buying cheap sectional radiators, their service life is less than 10 years.

Do not forget that in steel panel radiators, as a rule, fasteners, Mayevsky taps, plugs are included with the radiator, and in sectional radiators, as a rule, all this must be bought separately.

Which heating radiators are best for a private house

For a private house, steel panel radiators are best suited. They have optimal price quality, better heat dissipation than other radiators.

My top 5 steel panel radiators for a private house:

PURMO

KERMI

VOGEL & NOOT

BUDERUS

WIESSMANN

PRADO

LIDEA

CALOREE

I am from the Krasnodar Territory, so you may not have some brands of radiator manufacturers, and you probably have other brands that are no less worthy. Of all the brands of radiators I've worked with, these are the ones I love.

What heating radiators are best for an apartment

For apartments, bimetallic radiators are best suited. But, if the operating parameters of the heating system are below 5 bar, the heating system is not directly connected to the heating networks, but through a heat exchanger, the developer and management company did not indicate which radiators need to be installed, then aluminum, steel or cast iron radiators can be supplied.

There are a lot of restrictions, dubious benefits, risks to flood neighbors, so I believe that it is best to install bimetallic radiators in apartments, which, in principle, are indicated by the developer in 99% of cases.

My top sectional radiators:

RIFAR

GLOBAL

MONLAN

I repeat, I am from the Krasnodar Territory, so you may not have some brands of radiator manufacturers, and you probably have other brands that are no less worthy. Of all the brands of radiators I've worked with, these are the ones I love.

Install reliable radiators in apartments, in case of leakage, there will be sad consequences. In a private house, when heating leaks, part of the laminate may swell, but in an apartment, when you fill in your neighbors, you can stick in for a large amount.

Do not save on heating radiators! And check what your builders put in your apartment. You surely trust them? They will install cheap heating devices, and if there is a leak, you will pay your neighbors.

False information written by radiator manufacturers

Many manufacturers overestimate the performance of their radiators. This is mainly heat output. A striking example is the Lammin ECO AL500-80 radiator.

They say that the heat output is 190 W from each section, but in fact it is 128 W. Almost half overestimated heat transfer.

We all know that heating is heat loss compensation... Relatively speaking, we have a room with an area of 20 m², in which we need to install a radiator of some capacity. Some of you, and perhaps your would-be heating installers, have heard that 1 radiator section should be installed on 2 m². Someone heard the figure of 100 W per 1 m², so they are guided by it.

Imagine two scenarios for the development of events, one with would-be installers, the second with normal installers like us.

Woe-heating installer

Option 1. A room with an area of 20 m², so you need 20/2 = 10. I will install 10 sections, everything will be fine, this eccentric thought.

Option 2. A room with an area of 20 m², heat losses of 100 W per 1 m², which means 20 * 1000 = 2000 W. The power of one section of the Lammin ECO radiator is 190 W. To find out the number of sections, you need to divide the amount of heat loss by the section power, 2000/190 = 10.5. If you round up, then you need to install 11 sections.

Normal heating installers

We calculate heat losses in the program. It turns out that the heat loss of the room is 2700 W. We select a radiator based on many parameters, such as: appearance, room dimensions, and of course we are guided by the results of radiator tests.

Output

The unfortunate installer installed the radiator in 10 or 11 sections, let it be at the maximum: 11 sections. We consider: 11 sections * 128 W (actual heat dissipation) = 1 408 W. But in reality, you need to compensate for 2,700 watts. Of course, when it gets cold outside, it will be cold in this room. In fact, you need to add 10 more sections.

So it turns out that here the installer did not count, here the manufacturer deceived, and you freeze, my dear Customer.

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 associated with its organization, installation and maintenance has to be solved independently. That is, the question: "what are the best heating batteries for a private house?" is essential and relevant for a huge number of homeowners.

Not only the comfort of living in it in winter, but also the amount of material costs associated with heating and maintaining the house depends on how efficiently and competently the calculation is made, the selection and installation of heating devices is made. 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 easiest heating method, however, it also 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. The thermal power of their section is 80-160 W. 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 a 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 a large number of 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 may 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 thermal power 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 heating system of the house. 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 operating principle of the system, it makes no sense to install heating radiators in the house, 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:

We will separately consider the technical parameters of heating batteries of various 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	Price
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 of which heating radiators are better for a country house, one 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, the video will help you figure out which heating batteries are better to choose in a private house.

When building a new house or replacing an old heating system, the owner has a question - which heating batteries are better for a private house? The material of the publication offered to your attention is devoted to the answer to this question.

In private houses, in most cases, an autonomous water heating system is built on the basis of its own boiler. That is, the heat consumption directly affects the fuel consumption, and therefore - the payments for the energy carrier. Therefore, the more efficient the heating radiators work, the higher the overall efficiency of the complex and the lower the fuel consumption.

How to choose heating radiators for a private house, if you are guided by this statement? The choice of batteries should be made primarily according to the indicators of heat transfer from heating devices.

The heating system operates at low operating parameters - the coolant pressure does not exceed 3.0 kgf / cm 2, the water temperature is usually in the range of 60 - 80 0 С. Therefore, when choosing radiators, their strength characteristics can be neglected - they are quite enough for trouble-free operation ...

In addition, for aluminum and steel (including bimetallic with a steel frame) batteries, there are increased requirements for the chemical composition of the coolant. Aluminum requires that the pH of water (pH) be in the range of 7 to 8, steel has a negative attitude to high oxygen content.

In systems, the chemical composition of the coolant practically does not change - make-up is done very rarely. Therefore, the requirements for water from the radiators can also be neglected.

But it should be noted that this statement is true for closed-type systems - in complexes with natural circulation, an increased oxygen content is observed. In this case, cast iron radiators are definitely the best choice. They are not susceptible to corrosion, have a large flow section of the sections - this is a necessary condition for the natural circulation of the coolant.

Thus, it becomes clear that the main selection criterion (from a technical point of view) is the amount of heat transfer from the heating radiator. Radiators are made from 4 metals:

Aluminum;
Bimetallic alloy;
Steel;
Cast iron.

The thermophysical characteristics of these materials differ - the quality of heat transfer from radiators directly depends on this. For ease of comparison, we will summarize the information in a table.

Table 1. Summary characteristics of heat transfer of standard sections of radiators (500 mm), depending on the material of manufacture.

From the data in the table, a simple conclusion can be drawn - the best batteries for a private house are aluminum radiators. They are slightly inferior to devices made of an alloy of steel and aluminum, cast iron and steel products are outsiders. Steel even has a lower thermal conductivity than cast iron, but heats up faster due to the fact that the cast iron sections have a large wall thickness.

In addition, aluminum heaters are usually cheaper than all others. The most expensive are bimetallic radiators - they are also leaders in strength - but we said about this characteristic above.

Although to a lesser extent than in central heating systems, they are still subject to the corrosion process. The wall thickness of steel devices is usually 1.0 - 1.5 mm - this may not be enough for a long service life of the products.

The disadvantage of cast iron radiators is low maneuverability - they warm up for a long time and cool down slowly. Thermal regulation is widespread in modern heating systems - cast iron radiators react very poorly to regulation (slowly and irrelevant). In addition, cast iron appliances require periodic painting.

From all of the above, we can conclude that the best option for a heating device for a private house is an aluminum radiator. Devices of this type transfer heat as efficiently as possible - this has a qualitative effect on fuel consumption, aluminum products are usually cheaper than their competitors.

In addition to technical and economic selection criteria, design delights now play an important role - but it is difficult to recommend anything here. The reputation of the manufacturer is also an important factor. The market is saturated with low-quality products and it is better to overpay a little for a brand than to purchase a notoriously unreliable radiator.
