Rating of gas boilers. Rating of double-circuit gas boilers Rating of condensing boilers
The range of heating equipment is represented by companies from Germany, Russia, the Czech Republic, France, Korea and other countries. In total, heaters of about 50 different brands are offered, differing in thermal and operational characteristics, appearance and internal structure.
It is not surprising that the choice of a wall-mounted gas boiler turns out to be difficult even for a specialist, not to mention a simple layman.
Manufacturers of mounted boilers for gas
To facilitate the choice, you will need to consider several models of the most popular boilers in Russia. For convenience, all models are classified on a territorial basis. The list includes both the best firms from Europe and relatively recent concerns located in Asian countries.It is ultimately up to the consumer to decide which manufacturer is better. In addition to the thermal characteristics of the proposed equipment, it is worth focusing on the pricing policy and adaptation to domestic operating conditions.
Boilers from Russia
Wall-mounted double-circuit domestic gas heating boilers are offered by several dozen manufacturers, but domestic ones are the most popular:- Neva Lux.
- Elsotherm.
- Neva-Transit.
- Lemax.
- BaltGaz.
- Ease of installation and operation- heat generators have a design that is fully adapted to local heating conditions. Automation is not sensitive to voltage drops in the network, as well as pressure surges in the line.
- Low cost- boilers of Russian companies, offered at a price affordable to domestic consumers.
German boilers
The Germans are known for their almost impeccable quality, high automation of boiler operation and good thermal performance. Many enterprises in Germany that produce heating devices began their activities at the beginning of the last century, with the manufacture of heater tanks, rolled metal, etc.For a domestic buyer, products of the following brands are in demand:
- Buderus.
- Viessmann.
- Vaillant.
- Roda.
- Bosch.
- wolf.
Boilers from Korea
Firms from Korea that produce wall-mounted gas boilers initially focused exclusively on consumers living in Asian countries. But, the constant demand for products has led to the need to expand production capacity. The products became available to the domestic buyer.Boilers are manufactured by companies with many years of experience in the production of climate equipment: air conditioners, climate control systems, etc. Some concerns, in addition to boilers and air conditioners, also manufacture other products, up to cars. For Asian companies, this trend is the norm rather than the exception.
Double-circuit Korean gas wall-mounted heating boilers are offered by several companies:
- Navien.
- mastergas.
- Daewoo.
- Koreastar.
- HydroSta.
- Kiturami.
The equipment is characterized by maximum automation, with which the main claims of Russian buyers are connected. In conditions of unstable power supply, fluctuations in parameters in the main pipeline, the boiler automation often gives a signal to turn off or refuses to start the unit at all.
Despite the shortcomings encountered, Korean boilers continue to be popular due to the convenience and comfort during operation, as well as an acceptable cost.
Chinese boilers
Chinese wall-mounted double-circuit gas heating boilers are in demand, mainly due to their low cost. For the price of the budget version, the consumer is offered a heater with a complete set, almost a "premium" class.After installation, double-circuit wall-mounted Chinese heating gas boilers usually work flawlessly for the first 2-3 seasons, after which constant breakdowns begin, incessant calls for adjustment masters, etc.
The Chinese offer their products in the following modifications:
- haier.
- Olical.
Boilers from Italy
Single-circuit and double-circuit wall-mounted Italian gas heating boilers, judging by sales statistics, are the most popular water heating equipment. Manufacturers were able to combine European build quality and product compliance with EU standards, while maintaining an attractive cost for a potential buyer.Italians offer products of the following brands:
- Baxi.
- Beretta.
- Tiberis.
- Fondital.
- Sime.
- Ferroli.
- Immergas.
- Ariston.
Almost the only drawback of the produced heating devices, judging by customer reviews, is the sensitivity of automation to voltage drops in the network. Therefore, it is categorically not recommended to operate the boiler without voltage.
Japanese boilers
Wall-mounted double-circuit Japanese gas heating boilers, first of all, are small in size and compact. Traditionally for the countries of the Asian region, the boilers are automated as much as possible.In Japan, there are strict sanitary and environmental regulations, which significantly affected the products and affected their quality. Another difference between Japanese heat generators is that they are produced exclusively with a closed combustion chamber. Atmospheric heat generators are prohibited in Japan.
The Japanese offer products from only two manufacturers:
- Rinnai.
- Kentatsu.
Boilers made in Japan use surgical stainless steel, which ensures compliance with all sanitary and food regulations in force in the Russian Federation.
Boilers from the Czech Republic
Czech hinged gas heating boilers with one and two circuits are a cross between Italian and German products. High build quality, almost identical to what is offered at factories in Germany, but at the same time, the pricing policy is somewhat lower.Czech wall-mounted gas heating boilers are available both with a classic atmospheric burner and with a turbocharged, closed type.
The Czechs offer their heaters of the following brands:
- Protherm.
- Thermona.
French boilers
French manufacturers of mounted gas-fired boilers offer high-tech equipment with innovative design solutions. On the basis of enterprises, for the first time in the EU, the production of pulsating combustion boilers was launched.Copper is often used as the main material of the heat exchanger, which increases the cost of production, but at the same time increases the thermal efficiency of boiler equipment.
All brands of boilers manufactured by French companies have about a dozen different items, but according to a statistical report, only two models are popular among domestic consumers:
- De Dietrich.
- Chaffoteaux.
The domestic buyer, French products, is not in such demand. The Russian consumer prefers boilers of German and Italian companies.
What are the parameters to choose a hinged gas boiler
Choosing the right model of heating equipment, you can not do without the advice of experts on the choice. Recently, experienced consultants were invited to answer the most common questions from buyers regarding the following aspects:- Selection of the boiler by power.
- The number of contours.
- type of combustion chamber.
- Heat exchanger configuration.
What power to choose a boiler
The choice of boiler power is the main aspect of the competent selection of heating equipment. It is with the definition of this parameter that the search for a suitable heater begins. Calculations are performed in several ways:- Thermal engineering calculations- Conducted by a competent engineer after auditing the premises for possible heat loss. The method is optimally suited for determining the power of boiler equipment for rooms with a total area of over 250 m².
- - you can choose a boiler using special software offered on the site. Calculators perform the same calculations as a heating engineer, but without the need for financial outlays. Some programs, after entering information, automatically select several models of boilers that are suitable for the parameters of the building, heating system and hot water.
- Independent calculations- calculations are made according to the formula 1 kW = 10 m². This formula is intended for buildings with an average degree of thermal insulation located in mid-latitudes. To the result obtained, it will be necessary to add a power margin, in case of severe frosts, within 15%, as well as an additional 20% performance, for hot water supply.
How many contours are better
Some practical selection advice received from company consultants concerns the number of circuits installed in the boiler. There are no ready-made solutions in this matter.A single-circuit or double-circuit boiler is selected specifically for the thermal characteristics and actual needs of the heated building:
- Single-circuit boilers- suitable for heating residential premises, in the absence of the need for hot water. If necessary, the device is modified by connecting an indirect heating boiler. It will not work to install a storage tank in the conditions of a limited living space in an apartment, which must be taken into account when choosing a boiler.
- Double-circuit heat generators- work on heating and hot water supply. For ease of use and increased efficiency, wall-mounted double-circuit German gas heating boilers are often equipped with a built-in storage boiler connected to the recirculation system. The same device is also available in boiler equipment manufactured in Italy, the Czech Republic and France.
The advantage of a boiler integrated into the body, the ability to get hot water, almost instantly. In the summer season, the consumption for DHW heating is reduced by approximately 15-20%.
In Russian-made double-circuit wall-mounted gas boilers, a built-in indirect heating boiler is not provided. Hot water supply is carried out by means of a flow-through method of heating water.
Which combustion chamber is better
Boiler equipment is equipped with a combustion chamber of two types. The requirements for installation and further operation depend on the configuration:- Models with a closed combustion chamber- the burner is located in a sealed chamber, the air into which is forcibly supplied by means of a turbine. Additionally, a fan is installed that removes combustion products.
Forced draft models are volatile and cannot operate without electricity. At the same time, the requirements for installation and operation make it possible to mount boilers with a closed combustion chamber in almost any non-residential building, cover the body with a decorative panel, build it into furniture, etc. - Atmospheric convection boilers with an open combustion chamber- a burner is installed that burns the air taken from the boiler room. For the most part, the open chamber design is found in non-volatile wall-mounted boilers. High-quality models are made by Russian manufacturers.
Non-volatile boilers with an open combustion chamber are best suited for heating buildings located in areas where there are constant power outages.
Which heat exchanger is better
The choice of a wall-mounted gas boiler for heating and hot water heating is associated with determining the design of the heat exchanger. Manufacturers use two types of water circuits:- Two heat exchangers– the internal device has two separate water circuits operating in a constant mode. Heating of water and the heat carrier occurs simultaneously. The primary heat exchanger is made of stainless steel or aluminum alloy. The secondary circuit is made of copper.
In a wall-mounted boiler, taking into account the quality of the water, a separate type heat exchanger is better. Heating circuits are less likely to fail. And when the DHW is completely turned off due to overgrowing with scale, the heating circuit continues to work. The disadvantage of the design is the greater weight and dimensions associated with the placement of the second heat exchanger. - Bithermic heat exchanger- represents a design that is similar in internal structure to a coaxial pipe. Heating of the heat carrier and hot water is carried out in alternating mode. According to technical indicators, the design is inferior to a device with two separate heating circuits. In the conditions of domestic realities, bithermic boilers often fail.
Rating of mounted boilers by reliability
The rating of wall-mounted single-circuit and double-circuit gas boilers depends on the type and design of the proposed models, operating conditions and functional features:- Boilers of condensing type- the leading positions are occupied by heating equipment of German manufacturers, French Chaffoteaux and Japanese Rinnai create some competition for them. In all these models, high-quality stainless steel and high-tech automation are used.
- Double-circuit boilers with a natural chimney(open combustion chamber). The optimal solution is the purchase of a domestic heat generator with a separate heat exchanger. In conditions of low quality of the coolant, the boiler will last longer than the Italian counterpart.
- Double-circuit and single-circuit boilers of closed type- reliability rating, headed by German heat generators, second place, shared by the French and Czechs. Italian equipment with a bithermic heat exchanger, without service, will last no more than 5 years. A good solution may be the acquisition of Japanese technology.

*Overview of the best in the opinion of the editors of the site. About selection criteria. This material is subjective, is not an advertisement and does not serve as a guide to the purchase. Before buying, you need to consult with a specialist.
In Russia, gas is the most affordable type of fuel. That is why the owners of houses, cottages and small businesses prefer to heat the premises with a gas boiler. The old Soviet cast-iron devices have been replaced by elegant and lightweight models. Foreign brands have penetrated the domestic market, which are seriously competing with Russian equipment. On the one hand, the range of boilers has expanded, and on the other hand, buyers have problems choosing the right model. Expert recommendations will help you find the best option for your home in the sea of gas boilers.
How to choose a gas boiler
- The number of contours. The choice should begin by determining the number of contours. Single-circuit models are able to provide heat to the heating system. To heat the water, you will have to buy an additional boiler. But double-circuit boilers simultaneously heat the house, providing residents with hot water.
- Mounting. According to the type of installation, floor and wall devices are distinguished. Floor-standing models boast higher power. However, they are bulkier and heavier. Wall-mounted boilers look more elegant, they save space in the boiler room, which is important in cramped back rooms.
- Power. The most important parameter of the heating device is thermal power. For houses with good insulation and standard rooms (height 3 m), it is customary to determine the power indicator using a simple formula. With the help of 1 kW of heat energy, an area of 10 square meters can be heated. m. In old houses with poor thermal insulation, it is necessary to install a boiler, the power of which is 20-50% higher than the calculated one. A double-circuit boiler is also selected by about 20% more powerful so that the heating of hot water does not adversely affect the temperature of the coolant. For example, for heating a dacha with an area of 70-80 square meters. m will be enough to buy a boiler with a thermal power of 8-12 kW. Large house or cottage with an area of more than 200 sq. m is able to heat the device with a power range of 22-35 kW. Experts do not advise chasing too productive models; frequent turning on and off the burner will strain the residents.
- Safety. Gas equipment refers to devices dangerous to human life. Therefore, it is necessary to study the security systems available in the boiler. The standard set of a modern gas boiler includes gas control, protection against overheating and pump blocking, self-diagnosis, and a safety valve.

Each time, when choosing heating equipment, the question arises not only of choosing the characteristics of the model, but also of the manufacturer, on which the quality sometimes directly depends. This also applies to the gas heat generator. The market offers many models of various price categories, from which it is not always easy to choose a gas boiler that meets all expectations. To simplify the choice, as well as save time searching for a quality product, there is a reliability rating for gas boilers.
gas boilers
For a general idea, you need to consider the classification of gas heating equipment that exists on the market:
- According to the method of natural gas combustion and removal, there are units with an open combustion chamber and a closed one.
- According to the efficiency of using the heat of combustible natural gas, there are convection boilers and condensing boilers. The second type saves fuel consumption by about 15-20%, moreover, it has a higher efficiency compared to a traditional boiler.
- According to the ability to heat water for the needs of hot water supply: single-circuit and double-circuit.
The first type is designed for space heating, often installed in rooms without water supply, while the second type is designed for heating and hot water supply. A double-circuit boiler saves space, but not the amount of water. In addition, it is demanding on operating conditions and equipment. A double-circuit gas boiler can be made from a single-circuit gas boiler by attaching a boiler to it. However, in this case, the volume of water supply will be limited by the capacity of the boiler, moreover, such a system will cost more than a compact two-circuit system.
By installation, boilers are wall-mounted, or suspended, and floor-mounted.The first type is used for installation in limited areas. The floor boiler is larger, but also more powerful, designed to heat a large area up to 600 sq.m. The wall analog has a power of 35 kW and is designed for heating buildings up to 100 sq. m, since the copper heat exchanger will not withstand a higher temperature.
- Classification of models by power.
After the choice regarding the characteristics has been made, you can proceed to the choice of a manufacturer offering quality equipment.
