Due to the fact that a large number of new, modified models of domestic and foreign production with different characteristics and price levels have appeared in the range of heating devices offered to consumers, nowadays it is possible to replace the old boiler with a more economical, compact and aesthetic one without any problems. Many owners decide to “kill two birds with one stone” with such an acquisition, that is, at the same time solve the issue of autonomous hot water supply. And it's not difficult now - they are offered a wide selection of double-circuit boilers.
However, such a high market saturation often contributes to the "opposite effect", that is, makes the choice of the optimal model a very difficult task. We will try to help in this - we will give a list of devices that are steadily included in the constantly changing rating of double-circuit, wall-mounted and floor-standing gas boilers. True, one can make a reservation: the authors deliberately did not award certain places to the listed boilers - just so as not to interfere with the subjective factor in this issue. The determining criterion was the positive feedback from consumers who have already tried this technique in practice. In a word, the boiler models indicated in the publication can be purchased with close to 100% confidence in obtaining a device of high assembly quality and with the expectation of its long-term operation.
Of course, when choosing any heating boiler, you need to pay attention to other criteria that affect the quality and durability.
The main criteria for choosing a heater
Double-circuit boilers are divided into floor-standing and wall-mounted.
- Floor double-circuit gas boilers, as a rule, are designed for a higher heat output than wall-mounted models, therefore they are most often installed in houses with a large area. However, for such heating devices with a power of 30 kW or more, a room separate from the living area is required. Therefore, before dwelling on the choice of such a model, it is necessary to study not only the technical characteristics and operating rules, but also the standards for the equipment of the boiler room.
On sale you can find models of floor-standing gas boilers that do not require a power supply for their operation - it is only important that gas supply is provided with natural or liquefied gas. These types of units are especially convenient for heating houses located in rural areas, where power outages are not uncommon. The design of non-volatile boilers is quite simple, but very reliable; such units are more durable than boilers with complex automation.
The efficiency of modern floor-standing models is 90 percent or more.
- Wall mounted Vukhkonturnye gas heating devices, as a rule, are compact in size, so it is convenient to install them in small houses or even in a city apartment.
Since such a unit does not take up much space, it is usually placed on the kitchen wall, where all the communications necessary to connect it are located. For the operation of almost all models of wall-mounted heating devices, an uninterrupted power supply is required. Power is required by both the circulation pump and the automation unit, and, in models with a closed-type combustion chamber, fans for air injection and combustion products removal.
Naturally, the installation of a gas boiler in the residential area of the house increases the requirements for organizing a more efficient ventilation system.
Unlike floor-standing boilers, in which steel or cast-iron heat exchangers are often installed, wall-mounted appliances, in order to reduce their weight, are often equipped with copper heat exchange elements.
The power of wall-mounted units usually varies from 9 to 30 kW.
Power of double-circuit boilers
In order for a heating and water heating device to be truly effective in operation, it is necessary to correctly calculate its power for a particular house or apartment.
Very often on the Internet you can find such a sign:
To be honest, such information, instead of a clear presentation, can cause the consumer, on the contrary, a lot of questions. Agree that the difference in price between 9 kW and 20 kW models will be very significant, and the range of options for such a "coordinate system" turns out to be impressive.
In addition, this approach does not take into account the peculiarities of the regional climate, the building itself and its individual rooms, the degree of glazing (that is, the number and size of windows) and many other important circumstances. Therefore, it seems more reasonable to carry out more thorough calculations, in which the calculation calculator below can help.
The basic principle is that calculations are carried out for each heated room separately, and then the results are summed up. This, by the way, gives the owners one more "preference" - having on hand such results of calculations (and it is best to issue them with a plate - for each room separately) it will be much easier and correct to arrange heat exchange devices - radiators or convectors - in the rooms.
Gas boilers Is the best solution for gasified premises. The main advantages of using gas boilers: they are easy to operate and maintain, compact, suitable for heating a private house and non-residential premises.
Technical characteristics and types of gas boilers
When choosing a gas heating boiler, one should take into account its main characteristics: type of combustion chamber, number of circuits, type of installation.
According to the installation method, gas heating boilers are:
- floor-standing: such boilers are characterized by high power, long-term operation, but it is recommended to allocate a separate room for them;
- wall-mounted (mounted): they are lightweight, compact, their cost is much lower than the price of floor-standing ones.
Today, both single-circuit gas boilers, which provide only heating, and double-circuit ones, are equally popular. The functions of the latter include both heating and water heating. It is the boilers with two circuits that are most often purchased for home and summer cottages.
The following boiler models are distinguished by the type of combustion chamber.
- With an open combustion chamber - oxygen in this case is consumed from the room in which the equipment is installed.
- With a closed combustion chamber (or a turbocharged gas boiler) - receives oxygen from the street. Such models have several advantages:
- easy installation and operation;
- high efficiency;
- security;
- the need to use a simple coaxial chimney with a small diameter.
Where to buy a gas boiler?
In the Teplomatika company you can buy online gas boilers wholesale and retail. Our qualified employees will carry out the installation and connection of heating gas systems. We are selling products of the highest quality at affordable prices.
You can order a gas boiler in several ways - by sending the product to the basket or making a purchase in one click. All information about the terms of delivery is contained in a separate one.
When choosing a gas boiler for a home, you need to take into account a number of nuances related to the technical characteristics of the building, the installed heating system, the actual need for heat and hot water supply.
Domestic and foreign manufacturers offer a wide range of products. So finding a suitable specimen is not a problem. You just need to know what to focus on in order to understand how to choose a gas boiler for heating and not be mistaken. And it is also advisable to figure out how the options presented differ from each other, and which boiler to choose for a private house.
There are very few external differences in boilers of various modifications.
Features of gas heating
Despite the presence of a large number of alternatives (electricity, diesel, diesel fuel, fuel oil, firewood, coal), it is gas heating that still leads the world. And there are good reasons for this:
Profitability. Compared to other options, gas is relatively cheap and highly efficient. In this case, not only the cost of the fuel itself is taken into account, but also additional expenses for its storage (for the consumer), maintenance of the entire system, etc. So, parts for rare types of boilers can be difficult to get, sometimes you have to overpay. This is also taken into account.
Minimum human involvement. Heating a room with wood or coal requires a mechanical addition of fuel. Here everything is automated, including gas supply and flame control.
Cleanliness, absence of soot, soot and other things. Boilers can be easily installed in the kitchen.
The possibility of heating large rooms. One powerful boiler can handle a building on several floors.
At the same time, gas heating has its drawbacks. Or rather, specificity.
Installation should only be carried out by specialists. Source nehomesdeaf.org
In particular, the installation of the boiler requires approval from Gaztekhnadzor. Installation can only be entrusted to an organization with a license that gives the right to provide such services.
Do not forget that the gas is explosive. Therefore, it is extremely undesirable to save on automation: it monitors, among other things, its leakage (we are talking about modern technology).
In addition, you need to take care of ventilation. Combustion products can be naturally discharged from the building. But if problems arise with the draft, you need to change the installation location of the boiler (which is not always possible) or provide it forcibly.
Gas boilers for heating a private house: what they are
There are many different boilers on the market now. And you need to figure out how one type differs from another for the consumer. So it is easier to understand what to choose - a floor-standing gas boiler for heating a private house, or a hinged one, and with what functions, so as not to be mistaken. After all, otherwise you will have to either endure the inconvenience, or else spend extra money.
Single and double-circuit boilers
One of the main classification methods is the division into single and double-circuit boilers. The latter heat water not only for the heating system, but also for domestic needs. That is, there is no need to install an additional boiler.
The difference between single and double-circuit boilers Source remstrdom.ru
In a word, double-circuit gas boilers for heating a house are designed so that cold water from the central water supply system gets to them. Then the liquid heats up. In addition, there is a special valve in the design. It regulates where the hot water will be supplied. If you do not wash anything, do not take a bath, the boiler works to provide the heating system. But as soon as the tap opens, the valve closes the device. And water begins to flow to people.
Consider one more important point: to be able to take a bath, and not a contrast shower, you need a boiler with a capacity of at least 28 kW. The exact figures already depend on the size of the heated rooms and on the number of consumers. Roughly speaking, the more people need to wash, for example, the higher the load. And the more powerful the heater should be.

Can single-circuit boilers be used to heat domestic water? Yes, many modern models allow it. But you have to buy a boiler. It must be connected to the boiler, and in any case, the whole process, starting with the selection of a suitable model, should be entrusted to a specialist. Most consumers, however, in such situations usually just take a separate boiler, powered by electricity.
An example of a combination of a heating boiler and an indirect heating boiler Source nehomesdeaf.org
Which is the best option? Mostly they prefer double-circuit boilers: they are more convenient. But keep in mind that such models are always more expensive. The choice, in any case, depends on the consumers.
Floor-standing and wall-mounted boilers
The boilers may also differ in location in space: there are heating boilers for a private house, gas floor and wall. The latter take up less space and are generally more compact. In addition, they can be installed almost anywhere, subject to certain requirements. Also, for wall-mounted boilers, it is not necessary to organize a separate chimney: usually everything is solved at the expense of a pipe through which combustion products are removed.
What is the difference between floor-standing gas boilers for heating a house (they are officially called so)? They tend to be more powerful and noticeably heavier. For such models, more space is required: firstly, for the outline, and secondly, for the chimney. And this is not to mention a set consisting of a single-circuit boiler and a boiler. In addition, such specimens are quite noisy, so they are usually installed in a separate room (boiler room).
Most often, the boiler room is equipped in the basement or basement.
The choice of the optimal solution depends on what exactly you need in a particular case. That is, for an apartment or a small summer cottage, the best gas boiler for heating is a wall-mounted one. For a large house - floor-standing.
But when buying, you need to take into account another factor that can become critical: dependence on electricity. Floor-standing boilers work stably in this regard. Even if there is no electricity in the house, the heat will still remain. True, now more and more models with automation are being produced, which removes this advantage. Nevertheless, options can be found.
But all floor-standing models depend on voltage: power surges can disable equipment. Of course, no one bothers to put the stabilizer. But, firstly, this is an increase in costs. Secondly, the issue of power outages remains.
In general, both floor and wall products have their own advantages and disadvantages. Therefore, it is worth figuring out how to choose a gas boiler for a private house, depending on the specific room, on the quality of the electrical network and on financial capabilities.

Boilers with open or closed combustion chamber
Boilers can be with an open or closed combustion chamber. The former take air from the environment. Therefore, the issue of ventilation in this case becomes critical.
Ventilation is needed even more powerful than for a gas stove Source teplo-ltd.ru
There is a risk that oxygen will eventually run out. These models are considered obsolete in the EU, where they are widely abandoned due to increased safety requirements.
At the same time, boilers with an open combustion chamber are distinguished by a simple design. Therefore, they are less likely to fail (if we compare models in a low price category), are cheaper, and installation is easier. And it won't be difficult to find specialists who will deal with them.
Variants with a closed combustion chamber are considered more modern. They are safer, but require the installation of a chimney. However, this is just the case when you can spend money on the purchase of an expensive model and on installation once, and then not worry that there will not be enough oxygen in the room. Or that someone will suffer from poisoning with combustion products, as is the case with problems with boilers of the first type.
But the closed-camera models have their drawbacks. For example, you have to install a ventilation system that needs electricity. What, firstly, makes such a structure dependent (along with the light, heat will also disappear), and secondly, it increases the cost of providing a house.
Such a boiler needs supply and exhaust ventilation Source aquagroup.ru
The easiest way to stop is on boilers with a closed combustion chamber with a pipe leading to the outside. But for the installation of this model, there are far from always technical possibilities. So it is difficult to say in this situation which boiler to choose for the house. You need information about the object, whether it is possible to organize a separate room or bring the pipe outside.
How to choose a boiler for heating a private house
When choosing a gas boiler, you need to consider not only what they are. There are many more important parameters. Let's figure out what is worth paying attention to.
How to choose a gas boiler for a private house by power
It should be noted that it is very important to calculate the appropriate power, that is, no less and no more. With the first, everything is clear: the building simply will not warm up enough. But why is it undesirable for the boiler to be more powerful? In this case, the heating system starts to work unevenly, which leads to excessive wear. The result is frequent repairs and premature boiler replacement. In addition, the gas consumption increases.

Clearly about the choice of power in the video:
So how do you make the calculation? In general, it is best to contact experienced professionals with this. The fact is that when calculating, you need to take into account a huge number of different factors:
number of floors;
ceiling height;
the presence or absence of thermal insulation, as well as its type;
year of construction of the house;
wall material;
the selected method of heating water;
climatic zone.
And that's not all! It also matters whether the boiler is selected for townhouses or for ordinary houses (the former are usually warmer, although there are enough nuances here). The calculation is also influenced by the presence of other sources of heating in the building, for example, underfloor heating. In addition, an experienced specialist always specifies what the average room temperature should be. After all, there is a big difference between + 15 and + 23 degrees Celsius.
You can make an approximate calculation like this: you need to multiply the area of the house by the indicator of the climatic zone, and divide the resulting amount by 10. This option is suitable for typical buildings with a ceiling height of up to 3 meters.
Let's say a building is located in the northern regions of Russia. There, the climatic coefficient is 2 kW. Therefore, the boiler must be 20 kW. But for a double-circuit, this figure must be multiplied by ¼. That is, the result is 25 kW. And remember that he is exemplary!

Which boiler is better for a private house: the question of the chimney
Boilers with an open combustion chamber usually do not have a chimney. But in this case, it is necessary to ensure the removal of combustion products. And take into account that some part can still get into the air of the room. Therefore, for the safety of people, it is best to install such boilers in a separate room.
If we are talking about a closed chamber, then a forced draft is created there. And since the size and cross-section of the chimney does not affect the passage of the air flow (blowing depends on the fan), the installation is carried out using a coaxial pipe. It is easy to install and has a small diameter.
Turbine boilers are another popular option. Here, the air supply is provided by a special fan. Combustion products are discharged directly into the street. Moreover, the hole, as a rule, is small (it is visible from the outside).
When choosing this model, you can refuse to organize a chimney. But turbine structures need to be cleaned from time to time: if the entrance is clogged from the street, for example, with leaves, then the boiler will stop working.

Each solution has its own advantages and disadvantages. But remember: only models with natural draft are considered non-volatile! So if electricity is often cut off in your village or area, then the only option would be products with natural draft and without a chimney.
Which boiler is better to choose for heating a house: manufacturers
There are a lot of options on the market. And there are more and more of them every year. What to do? Try to understand the range.
So, the most reliable ones are usually offered by Germany. These are Vaillant, Bosch, Buderus, Volf. Italian manufacturers produce copies with an optimal ratio of price, service life and reliability. Among the most famous is Ferrolli. Of the less promoted - Baxi, however, the brand is not very well known in Russia, but in Europe it has long and deservedly enjoyed a good reputation.
South Korean Kiturami will be an ideal option for heating large spaces. If the budget allows, you can pay attention to the Japanese company Rinnai. Its boilers are environmentally friendly, safe and extremely reliable: the warranty is given for 10 years. In addition, the automation itself regulates the operation of the device depending on the gas pressure.

Of the domestic producers, Borinskoye LLC should be noted. The company's boilers are universal, suitable for most heating systems. Manufactured from high-strength steel types. Zhukovsky boilers are also well known to many. Produced in the Moscow region, they attract surprisingly affordable price and simple design.
It is difficult to say which option is better here. Much depends on what exactly you are counting on.
Which gas boiler is better to choose for heating a private house: price
Prices for boilers, in terms of the US dollar, start around $ 250 and go up to several thousand. Moreover, this amount does not always include delivery, and installation in most cases is paid separately.
In general, a double-circuit boiler is more expensive. But if we compare it not with a single-circuit, but with a set of a boiler and a boiler, then the calculations are no longer so unambiguous. More money will have to be spent on the chimney option. And the most affordable one is a floor-standing single-circuit boiler with natural draft of domestic production.

True, paying less for the product does not mean that the issue of savings has been finally resolved, because if in a few years you have to undergo serious repairs or a complete replacement, then the benefit is frankly dubious. Therefore, it is undesirable to focus solely on the issue of price when buying a boiler.
The gas boiler is the heart of the heating system. It largely determines whether your house (or apartment) will warm up normally, how much you have to pay every month for utilities, whether there will be a problem with dampness, etc. Therefore, when buying a gas boiler, there is no need to rush. Moreover, there are many types of gas heating boilers on the market for a private house - for every taste and wallet. This means that you have the opportunity to choose the truly optimal option. We have considered the main criteria for choosing a boiler for heating a private house, and we hope that you will not have any problems when choosing this important equipment.
Currently, popular and demanded wall-mounted gas boilers are used for high-quality heating of premises. This is explained by the fact that gas is the most accessible and at the same time inexpensive fuel. Markets and supermarkets offer a large number of different models of gas boilers, which differ in technical characteristics and prices. Therefore, it is rather difficult to choose the appropriate option. To solve this problem, you should first study the technical characteristics of the best equipment produced by various manufacturers and compare prices.
Wall mounted gas boilers for heating - types
With the development of gas supply, heating of premises increasingly began to be carried out with the help of modern equipment in the form of gas boilers. This type of heating can be installed on the walls of private houses, apartments, summer cottages, industrial facilities.
Wall-mounted gas heating boilers on sale in the Russian markets appeared relatively recently, but have already become a fairly popular product. There is nothing surprising in this, since they have a number of significant advantages:
Wall-mounted heating boilers have different capacities and in this they are in no way inferior to floor-standing gas equipment. At the same time, the price for wall devices is slightly lower.
However, modern ones are not very cheap. condensing gas structures... But these models have up to 99% efficiency, so when using them, fuel is significantly saved. In the manufacture of such boilers, modern automation and new metal alloys are used. They have a low exhaust temperature, so they are practically fireproof.
All wall-mounted gas equipment according to the type of chambers is divided into two types:
Open heating devices in which air draft occurs naturally. In them, combustion products are emitted through the chimney. Combustion air is taken from the room.
Closed structures are equipped with a forced air ventilation system. For their work, they take air from outside the premises, and exhaust gases are thrown outside. Such models do not need an additional smoke exhaust system. In addition, they are small in size and weight.
Those who want to purchase a gas heating boiler will need to calculate the required capacity of the equipment. For every 10 sq. m. premises with a ceiling height of no higher than three meters, one kilowatt of device power will be needed. If the power of the boiler is not needed very much, then you can stop your choice on wall-mounted equipment. In addition, double-circuit wall structures can also provide hot water supply, as well as create additional heating circuits in the form of a "warm floor".
Tips for choosing a wall mounted gas boiler for heating
When choosing wall-mounted gas heating equipment, you need to pay attention to some characteristics:
When choosing wall-mounted gas equipment, do not forget that such boilers sensitive to water quality and the duration of their work is still less than that of floor-standing models.
The main suppliers of this equipment are foreign manufacturers:
To figure out which of the units is better and which one is suitable for certain needs, you should familiarize yourself with their characteristics.
