What brands of gas boilers are better. Rating of wall-mounted gas double-circuit boilers. Rating of floor gas boilers
Article last updated date: 01/11/2019
For heating private houses, it is most advantageous to use gas heating equipment. This is due to the fact that gas is still considered the cheapest type of fuel. Such equipment is safe, economical and efficient.
We present to your attention the rating of gas boilers, compiled on the basis of feedback from consumers and specialists. If you decide to install gas heating in your house, then the overview of the devices below will help you navigate the variety of gas-fired boilers.
Gas boilers are divided into two types.
convection
The most common among boilers. The principle of its operation is quite simple. Gas through the burner nozzles enters the combustion chamber, where the flame flares up. It heats the heat exchanger with water, which enters the radiators through pipes and heats the room. As soon as the water temperature has reached the required temperature, the heating stops. The products of combustion are removed through the chimney. The efficiency of such a boiler is 90%. The remaining ten literally fly out into the pipe.
If the outlet temperature is below 57 degrees, then condensation will form on the walls of the combustion chamber, heat exchanger and chimney, which can lead to breakdowns, soot formation, and also to a reduction in the life of the device.
To prevent this from happening, and also for more effective use thermal energy, was designed new type boiler.
Condensing
The efficiency of this device reaches almost 100% due to the fact that the energy is fully used for heating and no longer “flies into the pipe”. This was achieved with the help of another heat exchanger - a water economizer. That's where the couple carbon monoxide are cooled until condensation occurs, which accumulates in a separate tank. When the vapor is converted into a liquid, useful thermal energy is released, which is transferred to the coolant.
The condensing boiler is bulkier and is usually installed in a separate room. The cost of the device is twice as much as that of traditional boilers.
Popular brands
Demand creates supply, which is probably why the market gas equipment for heating is so great. The more manufacturers, the more new models appear in stores. For an inexperienced user, this is a difficult choice, especially since few people are familiar with well-known brands. Still, this is a piece goods, I bought it once and forgot for a long time.
Which manufacturer's products should be considered reliable and of high quality?
- wolf. The German company produces boilers with very high efficiency. It is not yet very well known in the CIS, but it deserves the closest attention. Even budget models are different good quality and have built-in automation to ensure the most efficient operation.
- Vaillant. Also a German manufacturer. The products of this brand occupy more than twenty-five percent among other companies in the European market, which indicates quality, reliability and popularity.
- Bosch. This brand does not need advertising, it has long been a recognized leader in the production of equipment.
- STS and Bentone. Swiss companies. They have expensive products, but very high quality.
- Ariston, Beretta, Lamborgini and Ferroli. The Italians have firmly occupied the middle price segment. Their products are good value for money.
- Dakon. The Czech manufacturer produces budget models. German quality components are used here, modern systems automation, as well as careful quality control.
Just don't think that Russian companies do not produce quality products. By purchasing equipment of domestic manufacturers, the user can count on low cost, reliability and durability, high performance, as well as the availability of components and good after-sales service.
- "Zhukovsky Machine-Building Plant". Produces heating equipment for over 40 years. In some boilers it uses imported automation. None of the models is independent of the mains. Efficiency - up to 92%. High degree of reliability and long service life.
- Borinsky. This plant has been dealing with boilers for more than two decades. Almost all models are equipped with high-quality foreign automation, are non-volatile, have a relatively modern design and affordable cost.
- Lemax. The Taganrog plant offers gas boilers with a special coating of heat exchangers that protects against corrosion. Models are also produced with cast-iron heat exchangers, which are rightfully considered the most reliable. All equipment has high efficiency and is non-volatile.

What features to look out for
In order to correctly and competently choose a gas boiler, carefully consider the following criteria.
- Power. The most important parameter. It completely depends on the area of the heated premises and the specific coefficient for the region of residence. For example, if you live in middle lane, then the value of the coefficient for every 10 m² is 1-1.2 kW, in the south - 0.7-0.9 kW, in the north - 2 kV. To calculate the power of a boiler for a house of 300 m² in a temperate climate, you need to carry out the following calculations: 300 * 1/10 \u003d 30 kW.
- Mounting method. Boilers are wall and floor. The first ones are compact, do not take up much space, are silent and affordable. The second ones are more powerful, bulky, and often require a separate room for their installation.
- The number of contours. Single-circuit devices are designed only for heating, double-circuit devices also provide hot water supply.
- Safety. It is desirable that the boiler be able to automatically turn off in all abnormal and emergency situations.
Important factors when choosing a device are the consumption of gas and electricity, efficiency, the availability of programmable conditions for night and day heating, price.
- Be responsible for calculating power. If it is not enough, then the room will heat up for a long time and cool quickly. A powerful boiler, on the contrary, will lead to overheating - this is an unprofitable use of resources.
- If there is no separate, well-ventilated room and chimney, then a natural draft floor boiler will not suit you. It is better to opt for wall-mounted boilers with forced draft.
- Do you already have hot water? Then you should not spend money on a double-circuit boiler.
- For a biometric heat exchanger, you need quality water without impurities. So if you do not have a water filter built into the water supply system, then you will not save on such a boiler, because scale in the heat exchanger is guaranteed to lead to a breakdown.
Conclusion
As you can see, the choice of a boiler should be treated responsibly and with knowledge of the nuances. It is better not to rely on chance, but to turn to professional gas workers. They will help to correctly calculate the power and advise which boilers are suitable for heating your premises.
When choosing gas boiler for the house, you need to consider a number of nuances related to technical specifications building, installed system heating, the actual demand for heat and hot water supply.
Domestic and foreign manufacturers offer a wide range of products. So finding a suitable copy 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 make a mistake. It is also desirable to understand how the presented options differ from each other, and which boiler to choose for a private house.

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 is still the leader in the world. And there are good reasons for this:
Profitability. Compared to other options, gas is relatively cheap and has a high efficiency. At the same time, not only the cost of the fuel itself is taken into account, but also additional costs for its storage (for the consumer), maintenance of the entire system, and so on. 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 the mechanical addition of fuel. Here everything is automated, including the flow of gas and control of the flame.
Cleanliness, lack of soot, soot and other things. Boilers can be easily installed in the kitchen.
Possibility of heating large rooms. One powerful boiler can cope with a building on several floors.
At the same time gas heating there are also disadvantages. Or rather specific.
Installation must only be carried out by specialists Source neohomesdeaf.org
In particular, the installation of the boiler requires coordination with 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, saving on automation is highly undesirable: it monitors, among other things, its leakage (we are talking about modern technology).
In addition, you need to take care of ventilation. The products of combustion can be removed from the building in a natural way. But if there are problems with traction, 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 are they
There are many types of boilers on the market today. 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 mounted one, and with what functions, so as not to be mistaken. After all, otherwise you will either have to endure inconvenience, or spend extra money.
Single and double circuit boilers
One of the main methods of classification is the division into one and double-circuit boilers. The latter heat water not only for the heating system, but also for domestic needs. That is, you do not 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 they get cold water from the central water supply system. Then the liquid is heated. In addition, the design has a special valve. It regulates where 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 another important point: in order 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 premises and the number of consumers. Roughly speaking than more people will need to wash, for example, the higher the load. And the more powerful the heater should be.
Video description
Clearly about the difference between single and double-circuit boilers in the video:
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, entrusting the entire process, starting with the selection of a suitable model, is worth a specialist. Most consumers, however, in such situations usually simply take a separate boiler that runs on electricity.
An example of a combination of a heating boiler and a boiler indirect heating Source neohomesdeaf.org
Which option is better? Basically, double-circuit boilers are preferred: they are more convenient. But keep in mind that such models are always more expensive. The choice, in any case, depends on the consumer.

Boilers can still differ in location in space: there are heating boilers for a private house gas floor and wall. The latter occupy less space are generally more compact. In addition, they can be installed almost anywhere if certain requirements are met. Also, for wall-mounted boilers, it is not necessary to organize a separate chimney: usually everything is solved at the expense of a branch pipe through which combustion products are removed.
What is the difference between floor gas boilers for heating a house (they are officially called that)? They tend to be more powerful and noticeably heavier. For such models, more space is required: firstly, for a stroke, and secondly, for a 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. Source makemone.ru
Choice optimal solution depends on what exactly you need in a particular case. That is, for an apartment or a small cottage, the best gas boiler for heating is wall-mounted. For a large house - outdoor.
But when buying, you need to take into account another factor that can become critical: dependence on electricity. Floor boilers are stable in this respect. Even if there is no electricity in the house, the heat will still remain. True, now more and more often models are produced with automation, which removes this advantage. However, options can be found.
But all floor models depend on voltage: power surges can disable equipment. Of course, no one bothers to put a stabilizer. But, firstly, this is an increase in costs. Secondly, the issue of power outage remains.
In general, both floor and wall products have their own advantages and disadvantages. Therefore, figuring out how to choose a gas boiler for a private house depends 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 open or with closed camera combustion. The first take air from the environment. Therefore, the issue of ventilation in this case becomes critical.
Ventilation is needed even more powerful than for gas stove Source teplo-ltd.ru
There is a risk that oxygen will eventually be lacking. These models are considered obsolete in the EU, they are widely abandoned there, due to increased safety requirements.
At the same time, boilers with an open combustion chamber are characterized by a simple design. Therefore, they fail less often (if we compare models in a low price category), they are cheaper, installation is easier. Yes, and finding specialists who will deal with them will not be difficult.
Options 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 buying an expensive model and installation once, and then not worry that there will not be enough oxygen in the room. Or that someone will suffer from poisoning by combustion products, as happens with problems with boilers of the first type.
But models with a closed camera have their drawbacks. For example, you have to install a ventilation system that needs electricity. Which, firstly, makes such a construction dependent (heat will disappear along with the light), and secondly, it increases the cost of providing a home.
Such a boiler needs a supply and exhaust ventilation Source aquagroup.ru
The easiest way is to stop at boilers with a closed combustion chamber with a pipe leading out. But for the installation of this model, there are not always technical possibilities. So it is difficult to say in this situation which boiler to choose for the house. We need information about the facility, whether it is possible to organize a separate room or take 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 take a look at what to pay 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 sufficiently. 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 replacement of the boiler. In addition, gas consumption increases.

Clearly about the choice of power in the video:
So how do you calculate? 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 affected by the presence of other sources of heating in the building, such as underfloor heating. In addition, an experienced specialist always specifies what the average temperature in the room 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 \u200b\u200bthe 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 the building is located in the northern regions of Russia. There the climate 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, as a rule, 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 forced draft is created there. And since the size and cross section of the chimney do not affect the passage of the air flow (blowing depends on the fan), the installation is carried out by a coaxial pipe. It is easy to install, besides it has a small diameter.
Turbine boilers are another option that is popular. Here the air flow is provided by a special fan. The products of combustion are removed immediately to the street. Moreover, the hole is usually small (it can be seen 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.
Turbine boiler ventilation Source spetsotoplenie.ru
Each solution has its own advantages and disadvantages. But remember: only models with natural draft are non-volatile! So if electricity is often cut off in your locality or area, then the only option would be products with natural draft and without a chimney.
Which boiler is better to choose for home heating: 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, Germany usually offers the most reliable ones. These are Vaillant, Bosch, Buderus, Volf. Italian manufacturers produce copies with an optimal ratio of price, service life and reliability. Of the most famous, it is worth mentioning Ferrolli. Of the less popular ones, Baxi, however, the brand is not particularly 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. Her boilers are environmentally friendly, safe and extremely reliable: a guarantee is given for 10 years. In addition, the automation itself regulates the operation of the device depending on the gas pressure.

Of the domestic manufacturers, Borinskoye LLC should be noted. The company's boilers are universal, suitable for most heating systems. Manufactured from high strength steels. Many people are also well aware of the Zhukovsky boilers. Produced in the suburbs, 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 reach 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 one, 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 option with a chimney. And the most affordable one is a floor single-circuit boiler with natural draft of domestic production.
Single-circuit floor boiler Source etechzone.ru
True, paying less for a product does not mean that the issue of saving has been finally resolved, because if in a few years you will have a serious repair or complete replacement, then the benefit is frankly doubtful. 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 depends on whether your house (or apartment) will warm up normally, how much you have to pay every month for public 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 for a private house on the market - for every taste and budget. This means that you have the opportunity to choose best 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 choosing this important equipment.
Coziness and comfort depend on optimal temperature and humidity level. The best gas boiler, which is of paramount importance for heating a private house, will help create the necessary atmosphere. To date, there are several main classifications of devices of this kind, each of which is designed for certain conditions of use. But first of all, gas boilers must be reliable, safe and efficient, how to figure it out and get the right one will tell the rating of gas boilers from the editors of the Mark.guru portal. It takes into account customer reviews of popular models, as well as the opinion of specialists in the installation and repair of heating systems. Now a little more about how to choose the best boiler and what criteria you should pay attention to.
The risk of acquiring is not entirely suitable model there is always, but to minimize this possibility, you need to calculate the purchase criteria.
- Power- the basis of the basics when purchasing a boiler, the efficiency of heating the room will depend on it. As a rule, 1 kW is enough to heat 10 square meters of area, if the ceilings in the house are higher than 3 meters, a small power reserve will be required. Also, double-circuit boilers will require additional calculation, because constant heating of water will require additional energy consumption and increased productivity.
- Layout- no less important for houses with a limited area. The double-circuit boiler is designed for drainage and heating of several systems - heating and hot water supply. The single-circuit gas boilers used are installed together with a storage boiler in which water for domestic needs will be heated. It will take extra bed, but this is not always possible.
- Location. A modern wall-mounted gas boiler can have a compact size and a presentable appearance that will fit perfectly into the interior, for example, a kitchen. As a rule, these are low-power models that are suitable for heating a house of 150 square meters. meters or less.
- Safety and reliability. The best gas boilers today boast automatic operation and self-diagnosis. Computerized systems are able to select the ideal programs to heat the room in the required temperature regime. In the event of a fuel leak, the boiler will turn off and signal a problem to the owner. And this is far from the limit of possibilities.

Conclusion
A reliable heating system is one of the most important components of a residential building, apart from the roof and walls. And if we choose a worthy device, it must certainly be safe, easy to manage and, if possible, economical. To help find the perfect boiler for a private home, the rating from the Mark.guru portal will help, we hope it will guide buyers in a huge range of boilers on the market.
Such boilers operate both in winter and summer mode, when only the hot water preparation circuit is in operation. Some new models additionally support several heating modes, including simultaneous, and, for example, allow you to connect both low-temperature underfloor heating (up to 40 ºС) and high-temperature radiator heating.
We offer you the latest rating for wall-mounted double-circuit gas boilers with the features of popular models. This short analytical review will help you decide on the brand and model of a new heating device, guided by price, quality and functionality at the same time.
Of the variety of offers on sale, you will find condensing and convection double-circuit boilers. There are practically no external differences in these boilers, while the water heating technology is significantly different. The condensing boiler is more modern, its price is much higher, it will also be characterized by lower gas consumption with the same heating. For this reason, if you are interested in a budget purchase, then it is better to choose the best convection versions of double-circuit gas boilers, if in reducing costs per month - a condensing model.
The latest offers are usually much more expensive. But their initial price is justified by a 20% fuel savings with the same heating parameters. If the cost is fundamentally low at the initial purchase, then subsequently it will be possible to reduce the cost of heating by purchasing a heat exchanger tank, which significantly increases heating efficiency by indirectly heating an additional volume of water. The presence of such tanks for wall models is uncharacteristic, but some high-rated floor versions have a heat exchanger tank.
The same principle - an additional heat exchanger - is used in condensing models, which is heated by hot gases, in convection models that go into the atmosphere. It is for this reason that significant fuel savings are provided at the same temperature of the batteries. also in individual models there are also economizers that improve power performance due to condensate vapors. For this reason, we recommend that you carefully read the description of suitable models.
You can choose from several options, including gradually increasing the power of the heating system, which, for example, is relevant for individual houses in which new living quarters are built. In this case, a cascade connection of heating devices using a hydraulic arrow can be used.
The best condensing models of double-circuit boilers
So, we have decided that condensing models are better and much more economical. At the same time, their cost can be 1.5-2 times higher than the similar convection version. In the case of buying a European-made boiler, you should pay attention to the objectivity of the cost compared to similar Russian or Czech ones. For Italian and German boilers, you will probably have to pay extra for the brand. This is not always justified, especially if other, no less optimal versions are available to you.
According to surveys, the first two positions are occupied by models:
Baxi will be one and a half times cheaper. These Italian boilers are highly valued by consumers, but it must be borne in mind that they are suitable for heating systems with a water coolant. If you are using a different liquid, Baxi will not work for you. Vaillant is even more demanding on the water coolant, distilled water is required.
Vaillant ecoTec plus VUW INT IV 246 is available in three powers - 24, 30, 35 kW. The efficiency is 108%. The boiler consumes electricity like a classic incandescent lamp - about 80-95 watts. The burner can be regulated and adjusted to burn from 20 to 100%, which in principle is the standard for wall-mounted boilers, not only from the rating. The maximum heating temperature is 85-86 ºС. Hot water is heated in the system up to 65 ºС.
This boiler has high reliability and environmental friendliness, high-quality built-in automation, including a frequency-controlled pump, a condensing economizer, a fuse, an air vent from the system, expansion tank, as well as pressure and flow sensors. The model can be converted to LNG fuel. This is true for houses remote from the center without a main gas supply system.
Unlike the previous model, the power of Baxi Duo-tec Compact 24 is only 24 kW. That is, this model is not suitable for a large house as the main heating device. At the same time, it has built-in weather-dependent automation, and automatically adaptive. This boiler is included in all consumer ratings of highly economical and user-friendly versions. It can be characterized as follows: minimum hassle - maximum efficiency. This is the optimal version for a wall-mounted boiler in a medium-sized house or apartment with individual heating.
Other popular condensing boilers
A good wall-mounted gas double-circuit boiler, which provides low gas consumption, can be selected among the brands Buderis, Viessmann, Bosch. In terms of quality and durability, German manufacturers, of course, win in the user rating.
Convection boilers will cost less, so the variety of the best models in the ranking is wider. According to the results of 2016 best models are considered:
- Wolf CGG-1K-24;
- Baxi Luna-3 Comfort;
- Bosch Gas 6000W WBH;
- Navien Deluxe;
- Protherm Cheetah.
Firstly, these are the so-called apartment turbocharged boilers, some of them have weather-dependent automation, which significantly reduces gas consumption. Secondly, models such as LUNA-3 allow installation in unheated rooms. This is sometimes necessary due to the peculiarities of connecting to the heating system, as well as in case of insufficient kitchen or hallway area. The listed models can be attributed to modern optimal heating devices.
The key element of the heating system of a private house is the boiler. In many respects, the air temperature in the room, the general costs associated with paying for heating, depend on how high the quality of the device itself, on the efficiency of its work. Wall mounted boilers have a major advantage over other similar heating equipment: they occupy a minimum amount of free space. There are a large number on the market various models wall-mounted units, which differ from each other in a number of parameters:
- Number of circuits: single circuits are designed exclusively for heating, double circuits will also provide the house with hot water;
- The type of combustion chamber is open (needs a natural chimney system) and closed (from it the combustion products are forcibly sent to the coaxial chimney, which is the safest);
- The presence of electrical devices;
- Type of burner: atmospheric or modulating, the power of which the boiler regulates independently.
When developing this rating of the best wall-mounted boilers of the year, we took into account all these features, we also took into account the opinion of customers, the country where the equipment was created and produced. We tried to compile the most understandable and informative rating, so that after studying it, it would be easy and simple for the reader to choose the most suitable heating boiler for his home.
