Heating private houses with gas is the most cost-effective in our country. Therefore, a gas boiler becomes one of the main elements of the heating system. The optimal option for heating living space with with total area 80-900 sq. m will be the installation of a floor heat source. The market offers consumers models from various domestic and foreign manufacturers. They differ not only in price, but also in important technical parameters.
- Everything can be divided by functionality gas boilers into single-circuit and double-circuit. The former are used exclusively for heating rooms. Models with two circuits are capable of not only providing heat to the heating system, but also heating water for the kitchen and bathroom. Despite a number of advantages of boilers with two circuits, experts do not recommend installing them in houses where bathrooms and kitchens are very far from the boiler room.
- Gas boilers also differ in the way they are controlled. Mechanical models are easier to maintain and repair, and electronic control allows you to achieve maximum comfort with complete non-interference in the work of the residents of the house.
- Structurally, condensing and convection boilers are distinguished. In convection models, the coolant is heated solely by the heat generated by gas combustion. With this classic scheme In order to obtain thermal energy, large losses occur. Modern condensing boilers. In addition to the energy from burning gas, they generate heat from water vapor, which is released during the combustion process. Water vapor is condensed in an additional heat exchanger, which ultimately allows saving up to 20% of hydrocarbon raw materials.

Disadvantages of the device: relatively high cost and sensitivity of the electronics to changes in mains voltage.
Since gas in Russia costs an order of magnitude lower than electricity, many owners of private houses are turning to installing gas boilers. However, economic parameters are far from the only advantage of units of this type over others - they include high thermal power, optimal level of efficiency, minimal amount of harmful emissions, as well as the ability to heat large areas (on average from 150 to 300 square meters).
Of course, like any other equipment, gas boilers have disadvantages. These include strict coordination of the installation with the federal Gaztekhnadzor service, equipping the house with a chimney to remove (a small amount) of combustion products, as well as the introduction of automation to detect gas leaks.
In our rating you will find 15 of the best and highest quality gas boilers, which can be purchased at long years will provide you with warmth and hot water. Before this, we advise you to study some of the nuances of choosing a gas boiler for a house or apartment.
The right choice - double-circuit or single-circuit?
As you know, according to the number of circuits, gas boilers are usually divided into single-circuit and double-circuit. Which one is better? The correct choice depends on the main purpose of the device.
Single-circuit ones are designed exclusively for the operation of the main coolant (radiators, pipes, etc.), that is, they are purchased to provide heating. Most often, such devices are installed in dachas and in places where there is no water supply. In this case, a boiler is purchased for a single-circuit boiler to heat water in an autonomous water supply system.
Double-circuit boilers are 2-in-1 devices. They can both heat a house and provide hot water supply. The coolant and boiler in such a device are assembled into one unit. If hot water is not consumed, the coolant circulates in the heating circuit. As soon as the user opens the hot water tap, the system switches the valves so that the coolant is directed to the second circuit. This is the most popular type of gas boilers, which are installed in most apartments and private houses.
Heating power
The more powerful the boiler, the higher its cost. In order not to overpay extra money and exclude additional expenses in the future (the more powerful the boiler, the more resources it consumes), it is important to calculate what power gas boiler you need. An approximate calculation is as follows: per 10 sq. m of a well-insulated room (ceiling height up to 3 m) should account for 1 kW of boiler thermal power. For a poorly insulated room, another 30–50% is added to the thermal power indicator.
For country house for 50 sq. m. it is enough to purchase a gas boiler with a capacity of 7 - 12 kW. But for a house with an area of 200 square meters. m. you will already need a more powerful device: 23 - 25 kW. Most modern double-circuit gas boilers produce a thermal output of 24 kW.
When choosing boiler power, there is one more important detail. If you take a device that is too powerful for a small room (for example, a 24 kW boiler for a one-room apartment of 40 sq. m.), the boiler will quickly heat up the coolant and turn off. As soon as the water cools down, the boiler will start again. Constantly turning on and off will occur very often, which will lead to accelerated wear and increased gas costs. In turn, a boiler with less power will ensure smooth combustion, and switching on and off will occur much less frequently.
Which company should you prefer?
The highest quality and most reliable gas boilers are produced by Italian, German and South Korean companies. Even taking into account the fact that many companies locate their production in China, purchasing a gas boiler from a popular brand is better than purchasing a little-known device.
To make your choice easier, here is a list the best manufacturing companies gas boilers:
- Navien (South Korea)
- Bosch (Germany)
- Ariston (Italy)
- Baxi (Italy)
- Buderus (Germany)
- Vaillant (Germany)
- Protherm (Slovakia)
- Viessmann (Germany)
- Kiturami (South Korea)
Voltage stabilizer for a gas boiler - is it necessary or not?
After purchasing a gas boiler, it is advisable to install a voltage stabilizer. Especially if your network suffers from frequent power surges. The fact is that if the boiler fails due to a power surge, it will not be possible to exchange the device under warranty. The requirement for network quality is specified in each warranty agreement. Therefore, it is better to spend an extra 3–5 thousand rubles for a device with a power of up to 1 kW (and powerful stabilizer not necessary for the boiler) than losing tens of thousands of rubles in the end.
The best inexpensive wall-mounted gas boilers
The main advantages of wall-mounted gas boilers are lower price and compact placement. They are more preferable for rooms with limited space. For example, for an apartment. The disadvantages of wall-mounted models are lower power and shorter service life, in contrast to floor-standing devices.

2 Baxi MAIN 5 24 F
Best quality
Country: Italy
Average price: RUB 37,820.
Rating (2019): 4.5
The Baxi MAIN 5 24 F gas boiler is an example of a double-circuit unit in the line of biothermal heating devices. An engineering solution that combined the heating circuit with the preparation of water for hot water supply in a single water supply unit made it possible to significantly reduce the cost of a wall-mounted unit compared to heat generators equipped with separate heat exchangers. However, there was no significant decrease in performance indicators. The boiler's power is sufficient to heat an area of 240 sq.m and prepare 9.8 l/min of hot water at 35°C.
The heat generator is designed to operate on natural and liquefied gas with a wide range of pressure in fuel pipelines. When connected to centralized gasification lines, the coverage ranges from 13 to 20 mbar. A high pressure threshold of 37 mbar is allowed when powered from mobile and stationary gas tanks. This indicator indicates the high reliability of the boiler’s fuel equipment.
Customer reviews emphasize that the most popular options for a gas unit are the ability to connect external control: room regulators, weekly programmers and the provided interface with low-temperature heating circuits (warm floors).

1 Vaillant turboTEC pro VUW 242/5-3
High efficiency with maximum reliability
Country: Germany
Average price: 53,700 rub.
Rating (2019): 4.5
The leading line in the rating is not the cheapest in the category, but the most reliable and efficient gas boiler Vaillant turboTEC pro VUW 242/5-3. The skill of German manufacturers knows no bounds: over more than ten years of production, this model has received mostly laudatory reviews regarding various aspects of its design and operation.
A double-circuit boiler can be used not only as a heater: when a source of cold water is connected to it, it copes with the functions of a boiler no less brilliantly. The maximum temperature of the DHW circuit is 65 degrees Celsius - for home use this is more than optimal. 24 kW of power is enough for heating residential areas up to 240 square meters. In this mode, Vaillant turboTEC pro VUW 242/5-3 shows the most high value Efficiency is about 91%. It is also worth noting the presence of six levels of protection, electronic control with the ability to modulate the flame, as well as a six-liter (generally standard) expansion tank.
The main disadvantages of the model affect the purely marketing side of the manufacturing company. The cost of servicing Vaillant boilers is very high, and the owner will bear the costs both for the purchase of a branded part and for its subsequent installation (approximately 50/50). Fortunately, serious breakdowns of units occur extremely rarely.
The best gas boilers with floor installation from the budget category
Floor-standing gas boilers are considered more reliable and durable. They cost more than wall-mounted models, but they are superior in power and can heat rooms from 200 square meters. m. To install floor-standing boilers, it is recommended to use a separate room (boiler room).
3 Protherm Wolf 16 KSO
The best automation. Developed service network
Country: Slovakia
Average price: 21,200 rub.
Rating (2019): 4.5
The non-volatile floor stand, presented by the Slovak company Proterm, is distinguished by its surprisingly miniature dimensions. Measuring just 39 cm wide, almost 75 cm high and 46 cm deep, it can easily be installed in any small space. The “Wolf” series includes 2 modifications, differing only in thermal power of 12.5 and 16 kW, sufficient for heating a private house with an area of 30 to 150 square meters. m.
The fact that the main production site Protherm is located at the Vaillant plant, a world-famous German manufacturer of gas boilers. Floor-standing units are made of 3 mm thick steel, equipped with temperature and emergency controllers, a draft stabilizer, as well as a SIT gas burner device (Italy). The design is easy to install and operate, and therefore does not cause any complaints from users. However, you need to take into account that the 2-year warranty on the unit applies subject to installation by a certified specialist.
2 ATON Atmo 30E
The most powerful gas boiler (30 kW)
Country Ukraine
Average price: 27,800 rub.
Rating (2019): 4.0
A powerful single-circuit boiler of Ukrainian origin, which has everything necessary to ensure stable heating of rooms up to 300 square meters. Actually, my main task ATON Atmo 30E performs beyond all praise - the absence of a second circuit for heating water allowed Ukrainian craftsmen to devote more attention and funds to improving and fine-tuning the heating function.
For normal operation, the boiler requires 3.3 cubic meters of gas per hour. This is quite a lot (especially for a budget model), but almost all the energy from the combustion of natural fuel (the efficiency of the unit is 90%) is converted into thermal energy, which, in combination with 30 kW of power, results in such a vast heated area.
In general, the presence of the principle of economy is felt in the model: the designer cut off almost all “civilized” functions, leaving the boiler with only the most necessary things - a thermometer, gas control and an overheating protection thermostat. This step led to a noticeable increase in the level of reliability, since a smaller number of components leads to a smaller number of possible (elementary) failures. In general, ATON Atmo 30E is an ideal boiler for a large country house, not burdened with additional functions and the need to work as a boiler.
1 Lemax Premium-25B
Largest heating area at an affordable price
Country Russia
Average price: 27,360 rub.
Rating (2019): 4.5
Lemax Premium-25B is an inexpensive floor-standing convection-type gas boiler. Produced in Taganrog. Capable of efficiently heating a house up to 250 square meters. m. with an efficiency of 90%. The low price of the device is due to the steel structure of the heat exchanger. This material is more susceptible to corrosion than copper and cast iron heat exchangers. However, the developer has provided a special thermal insulation coating with inhibitors, which should significantly reduce heat exchanger corrosion.
The boiler is equipped with everything necessary for safe operation of the system: heat exchanger overheating sensor, thermometer, gas control. There is an automatic ignition - ignition is carried out automatically. This indicates higher reliability and efficiency compared to devices with piezo ignition. The nominal pressure of natural gas is 13 mbar, that is, the boiler will operate at full capacity even at low pressures in the gas network (which is not uncommon in Russia). This is the best indicator in our review of budget floor-standing boilers.
It is worth noting that the Lemax boiler is designed for an open heating system, so when purchasing it, a chimney must be provided in the house to remove combustion products.
Most user reviews speak of Lemax’s “indestructibility” and almost silent operation. This is an economical and trouble-free boiler at an affordable price, with a 3-year manufacturer's warranty. One of the best offers in the budget segment.

Rating (2019): 4.5
The Logano line includes 4 standard sizes (from 20 to 32 kW) of low-temperature boilers, which are considered more profitable and safer than high-temperature ones. In addition, low temperatures in the heating system create maximum comfortable conditions for a person, while strong temperature changes in an apartment or private cottage are excluded. The unit can be integrated into the heating system using heated floors, and if the heat loss in the house is too great, it is possible to supplement it with radiators.
Additional heat savings are facilitated by the special design of the cast iron heat exchanger and 80 mm thick thermal insulation. So that buyers can customize heating device, the company offers a wide selection of additional parts and assemblies, which, it must be said, are quite expensive. For example, a control system flue gases They offer to buy AW 50.2-Kombi for almost 9.5 thousand rubles, and for the Logalux SU floor-standing water heater tank you will have to pay at least 50 thousand rubles. Nevertheless, consumers are satisfied with the efficiency, ease of operation and durability of the model and recommend it for purchase.

Country: South Korea
Average price: 34,000 rub.
Rating (2019): 5.0
In June last year, Navien Rus LLC was awarded the “Company of the Year” award in the “Best Supplier” category engineering equipment" A month later, the company celebrated the sale of its millionth mounted boiler in Russia with a 3-day conference. In addition, over the past 4 years, the brand has gained 46.6% of votes and has repeatedly confirmed the title of “Brand No. 1” in the “Heating Boilers” category. What is remarkable about his products that people vote for them not only with their words, but also with their wallets?
First of all, buyers are attracted by the quite reasonable price for the unit, the appearance of which speaks of the unsurpassed quality characteristic of South Korean technology. They are not disappointed even after meeting technical characteristics, in particular, the presence of a 2nd circuit, a closed combustion chamber and electronic system controls with remote control included. Despite its “overseas” origin, the model is fully adapted to Russian operating conditions and is designed to operate at a minimum gas and water supply pressure of 4 mbar and 0.1 bar, respectively.
1 Baxi SLIM 2.300 Fi
Best functionality and quality
Country: Italy
Average price: RUB 131,838
Rating (2019): 5.0
If you are looking for a high-quality and modern gas boiler from a trusted manufacturer, then Baxi SLIM 2.300 Fi is one of best options. This is the most expensive device in our review, with a price tag of about $2,000, which is quite acceptable for those who do not like to skimp on quality.
The double-circuit “Baxi” is capable of heating a cottage with an area of up to 300 square meters. m. with an efficiency index of 90%. Can operate in a closed heating system due to the built-in circulation pump. Built-in expansion tank will maintain optimal pressure in the heating system, accepting excess during heating and replenishing losses when cooling the coolant. Baxi SLIM 2.300 Fi is one of the best boilers for underfloor heating.
The primary heat exchanger material here is the best - cast iron. As you know, cast iron is resistant to corrosion, durable and reliable. Additional features worth noting are an air vent, a safety valve and protection against pump blocking.
Baxi SLIM 2.300 Fi is one of the best-selling floor-standing gas boilers in the middle and high price segment.
The best wall-mounted gas boilers based on the condensing principle of operation
During operation of a gas boiler, condensate is formed, which can be used to generate thermal energy. This is what happens in boilers of the condensing operating principle, where additional energy from the condensate is generated using a special heat exchanger (economizer). This undoubtedly increases the efficiency of the device.
Installing a condensing boiler allows you to save up to 20% on gas costs. Thus, the efficiency of a conventional convection boiler is on average 92%, while a condensing boiler is capable of operating with an efficiency of 109%. True, purchasing a condensing model will be much more expensive than a convection model and, perhaps, such a decision will be justified when heating sufficient areas.
3 Baxi POWER HT 1.450
Optimal performance and safety
Country: Italy
Average price: 147,000 rub.
Rating (2019): 4.7
Distinctive characteristics of the model are high power levels of 45 kW, efficiency of 107.5% and the ability to maintain 100% power when the input pressure is reduced to 5 mbar. The device implements everything modern methods protection, including protection against freezing, overheating, as well as gas control and an autodiagnostic system. The built-in microprocessor constantly monitors the status of the sensors and in the event of emergency situations (for example, a drop in water pressure, overheating or gas supply shutdown) automatically turns off the boiler. It is also worth noting the presence of automatic ignition, an air vent and the ability to connect a heated floor.
Baxi POWER HT 1.450 is one of the most reliable premium floor-standing boilers. The only obvious disadvantage of the device is its high price.
2 Baxi Duo-tec Compact 1.24
Profitable price. Minimum liquefied gas consumption
Country: Italy
Average price: 52,500 rub.
Rating (2019): 4.7
Baxi Duo-tec Compact 1.24 is one of the most affordable condensing-type gas boilers. Despite low price, the device power is 24 kW with an efficiency of 105.7%. This is an excellent model for installation in a country cottage or country house, since the boiler can operate on liquefied gas with a minimum flow rate of 1.92 kg/h. If desired, Baxi Duo-tec Compact 1.24 can be connected to the heated floor system. The built-in expansion tank will compensate for the expansion of the coolant. The Duo-tec Compact series features easy installation, simple operation and the ability to adapt to gas quality. They operate with a power modulation ratio of 1:7.
It is a pity that the boiler is single-circuit and can only be used for the heating system.
1 Protherm Lynx condensation
Combination high power and compactness. Auto control
Country: Slovakia
Average price: 57,000 rub.
Rating (2019): 4.8
In Europe, traditional boilers are practically not used - they have been replaced by condensing units like the Protherm “Lynx”. Models of this line have been produced since 2002 and still remain in demand on the market. There are quite a few reasons for its popularity: affordability – wall-hung condensing boilers with similar characteristics from competitors are 1.5 times more expensive, rich equipment, and a design that is still relevant today.
The forced exhaust system of combustion products allows the device to be installed in rooms without a chimney. Fuel consumption is 3.2 cubic meters. m./hour and provides savings of about 20–30% compared to convection devices. Thanks to two preset modes and an automatic control system with electronic display, set up in a private home desired temperature is not difficult. Additionally, the developers have provided the ability to connect an external controller. Users do not complain about any breakdowns, which allows us to judge the high reliability of the Lynx.
The best double-circuit boilers
When choosing a double-circuit boiler, as well as a single-circuit boiler, you need to pay special attention to power. If the residents of the house plan to take a bath frequently, the minimum power of the equipment should be at least 18 kW; if a shower is a priority, then it is permissible to install a less powerful unit - from 10 kW. Even before purchasing, it is advisable to check whether the manufacturer has skimped on circulation pump, safety valve, membrane expansion tank and fittings included.

Rating (2019): 4.5
Preparing hot water usually takes a long time. If you do not want to put up with such an inconvenience, take a closer look at the Bosch Gaz 6000 W WBN 6000-18 C boiler. Its plate heat exchanger is designed in such a way that water is heated in a matter of seconds. The presence of two separate heat exchangers makes the boiler more productive (30° - 8.6 l/min, 50° - 5.1 l/min) and not demanding on water quality.
Among other advantages of heating equipment, it should be noted that there is minimal noise - many users compare the sound of a working boiler to the noise of a computer or refrigerator. Economy is another Bosch feature. It is proposed to ensure this by turning on the “Eco” mode, which provides for heating water only when it is withdrawn. If you need maximum flexibility automatic adjustment, it is possible to connect external regulators to the built-in automation, allowing you to control the system remotely.
2 Ariston CARES X 15 FF NG
Fine temperature adjustment. Sophisticated security system
Country: Italy
Average price: 35,500 rub.
Rating (2019): 4.7
The Ariston CARES series is the most compact gas boilers in a traditional design and with a wall mounting method. The 15-kilowatt unit is intended for installation in heating systems of small private houses, cottages and apartments, in the limited space of which its dimensions - 400x700x319 mm - fit in quite well. And it’s very helpful that the unit’s settings allow you to set the temperature of the heating circuit with an accuracy of 1°, thereby ensuring an ideal microclimate in a small room.
The design is assembled according to a modular principle, due to which the quantity threaded connections– points of potential leaks – has become minimal. Built-in protective systems such as gas control, anti-freeze mode, and safety valve are responsible for uninterrupted operation and increased safety of the device. And at the same time, the manufacturer provides all the necessary options for comfortable operation - a large electronic display, auto-ignition, status indication and the ability to connect external control. Of course, this unit deserves a place in our rating!
1 Rinnai RB-207RMF
The best digital technologies. 18 Japanese patents
Country: Japan
Average price: 52,800 rub.
Rating (2019): 4.9
It’s not for nothing that the Japanese are known as techno-freaks – they even managed to stuff the Rinnai RB-207RMF gas boiler with the most modern electronics. What makes it unique, first of all, is the algorithm for automatically maintaining the optimal ratio of the gas-air mixture in the working chamber. The process is controlled by a “brain” with touch sensors. This achieves an unprecedentedly wide range of output power - from 17 to 100% and, as a result, a reduction in gas consumption and an increase in the service life of the primary heat exchanger.
You can control the model using the “Standard” (supplied in the basic kit), “Deluxe” or Wi-Fi remote control. With its help, you can program an individual heating and hot water supply mode, which will be maintained automatically depending on the indicators of sensors outside and inside the building. Changes in settings are duplicated by the voice navigator. Two microprocessors are responsible for safety, monitoring and correcting each other’s work. This is not a boiler, but space rocket, not otherwise!
