15 best gas boilers for the home

Since gas in Russia is an order of magnitude lower than electricity, many owners of private homes turn to installing gas boilers. However, economic parameters are far from the only advantage of units of this type over the others - they can be attributed to high thermal power, optimum efficiency level, the minimum amount of harmful emissions, as well as the possibility of heating large areas (from 150 to 300 square meters on average).

Of course, like any other technology, gas boilers have drawbacks. These include the strict coordination of the installation with the federal Gastechnadzor service, the equipment of the house with a chimney for the removal (minor 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 high-quality gas boilers, the purchase of which for many years will provide you with heat and hot water. Before this we advise you to explore some of the nuances of choosing a gas boiler for a house or apartment.

Is it the right choice - single or single?

As is known, by the number of circuits, gas boilers are usually divided into single-circuit and double-circuit. Which one is better? The right choice depends on the main purpose of the device.

Single-circuit designed exclusively for the main coolant (radiators, pipes, etc.), that is, they are bought to provide heating. Most often, such devices are put on cottages and in places where there is no water supply. In this case, to buy a single-circuit boiler, purchase a boiler for heating water in an autonomous plumbing system.

Double-circuit boilers are devices 2 in 1. They can both heat the house and provide hot water. The heat carrier and the boiler in such a device are collected in one node. 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 flows into the second circuit. This is the most popular type of gas boilers, which put in most apartments and private houses.

Heated 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 is, the more resources it consumes), it is important to calculate what kind of gas boiler you need. An approximate calculation is as follows: 10 square meters. m. of well-insulated premises (ceiling height up to 3 m) should account for 1 kW of heat output of the boiler. For poorly insulated premises, another 30–50% is added to the heat capacity indicator.

For a country house of 50 square meters. m. enough to buy a gas boiler with a power of 7 - 12 kW. But for a house of 200 square meters. m. already need a device more powerful: 23 - 25 kW. Most modern gas by-pass boilers are produced with a heat output of 24 kW.

When choosing the power of the boiler there is another important detail. If you take too powerful a device for a small room (for example, a 24 kW boiler for a one-room apartment of 40 sq. M.), Then the boiler will quickly heat the coolant on and off. As soon as the water cools down, the boiler starts up again. Continuous on and off will occur very often, which will lead to accelerated wear and increased gas costs. In turn, the boiler with less power will provide smooth combustion, and on-off will occur much less frequently.

Which company to prefer?

The highest quality and reliable gas boilers are manufactured by Italian, German and South Korean companies. Even taking into account the fact that many companies place their production facilities in China, purchasing a gas boiler of a popular brand is better than buying a little-known device.

To facilitate your choice, we list the best manufacturers of 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 gas boiler - needed or not?

After buying a gas boiler, it is advisable to install a voltage regulator. Especially if your network suffers frequent voltage drops. The fact is that in the event of a boiler failure due to a power surge, it is impossible to exchange the device under warranty. The requirement for network quality is spelled out in each warranty agreement. Therefore, it is better to spend an extra 3-5 thousand rubles for a device with a capacity of up to 1 kW (and you do not need a powerful stabilizer for the boiler) than to lose tens of thousands of rubles.

The best cheap wall gas boilers

The main advantages of wall gas boilers - lower price and compactness in placement. They are more preferable for rooms with a limited area. For example, for an apartment. The disadvantages of wall models are lower power and a shorter service life, in contrast to outdoor devices.

3 Navien DELUXE 24K

Gas boiler Navien DELUXE 24K - is the maximum comfort at the lowest cost. The double-circuit thermal energy generator is used for sequential heating of premises with a total area of ​​up to 240 square meters and to meet domestic and household needs in hot water with a capacity of up to 13.8 l / min at t 35 ° C. A distinctive feature of the heater in the material of the primary heat exchanger is stainless steel. This fact slightly reduces the efficiency of the unit to 90.5%, but prolongs its durability due to the reliability of high-alloy steel.

Comfortable use of the hot-water installation is ensured by a convenient display and visualization of the instrumentation, an adapted room controller with a remote control panel. The ease with which operative intervention is carried out in the cyclical operation of the boiler can significantly reduce the consumption of blue fuel during operation.

Stated in the reviews stable operation of the electronic circuit in conditions of periodic fluctuations in the voltage in the supply network, comprising +/- 30% of 230 V.Uninterrupted functionality is determined by the presence of a protective chip SMPS (Switched-Mode Power Supply), complementary to the microprocessor. The burning process in a closed chamber takes place without harmful failures and stops, which has a positive effect on the life of the equipment, excluding breakdowns.

2 Baxi MAIN 5 24 F

Gas boiler Baxi MAIN 5 24 F is a sample of a double-circuit unit in the line of biothermal heating devices. Engineering and technical solution, which combined the heating circuit with the preparation of water for hot water supply in a single hydroelectric complex, has significantly reduced the cost of the wall unit compared to heat generators equipped with separate heat exchangers. At the same time there was no significant decline in performance. The boiler power is enough to heat an area of ​​240 square meters and to prepare 9.8 l / min of hot water at t 35 ° C.

The heat generator is designed to work on natural and liquefied gas with a wide range of pressure in the fuel pipelines. When connected to centralized gasification mains, coverage ranges from 13 to 20 mbar. High pressure threshold of 37 mbar is allowed when powered by mobile and stationary gas-holders. This indicator indicates the high reliability of the fuel equipment of the boiler.

Customer reviews emphasize that the demand for options for a gas unit is the ability to connect external control: room controllers, weekly programmers and provided for interfacing with low-temperature heating circuits (heated floors).

Video Review

1 Vaillant turboTEC pro VUW 242 / 5-3

Leading the ranking line is not the cheapest in the category, but the most reliable and efficient gas boiler Vaillant turboTEC pro VUW 242 / 5-3. The mastery of German manufacturers knows no boundaries: for more than ten years of production, this model has heard mainly laudatory reviews concerning various aspects of the construction device and operation.

The double-circuit boiler can be used not only as a heater: when you connect to it a source of cold water, it is no less brilliantly coping with the functions of a boiler. The maximum temperature of the DHW circuit is 65 degrees Celsius - for home use it is more than the optimum value. 24 kW of power is enough for heating residential areas up to 240 square meters. With this mode, Vaillant turboTEC pro VUW 242 / 5-3 shows the highest efficiency value - about 91%. Also worth noting is the presence of six levels of protection, electronic control with the ability to modulate the flame, as well as a six-liter (in general, standard) expansion tank.

The main disadvantages of the model affect the purely marketing side of the manufacturer. The cost of servicing Vaillant boilers is very high, and the owner will incur costs for the purchase of branded parts, and for its subsequent installation (approximately 50 to 50). Fortunately, serious damage to the units is extremely rare.

The best gas boilers with floor installation from the budget category

Floor gas boilers are considered more reliable and durable. They cost more than wall models, but gain power and can heat rooms of 200 square meters. m. For installation of floor boilers it is recommended to use a separate room (boiler room).

3 Protherm Wolf 16 KSO

Non-volatile "napolnik", presented by the Slovak company "Proterm", has a surprisingly small size. Having only 39 cm in width, almost 75 cm in height and 46 cm in depth, it is easily installed in any small room. In the series "Wolf" there are 2 modifications, differing only in the thermal power of 12.5 and 16 kW, sufficient for heating a private house with an area from 30 to 150 square meters. m

The fact that the main production site of Protherm is located at the Vaillant factory, the world-famous German manufacturer of gas boilers, will tell a lot about the quality of production. Floor-mounted units are made of steel with a thickness of 3 mm, equipped with temperature and emergency controllers, a draft stabilizer, and a SIT gas-burning device (Italy). The design is easy to install and operate, and therefore does not cause complaints from users. However, it should be noted that the 2-year warranty on the unit is subject to installation by a certified specialist.

2 ATON Atmo 30E

Powerful single-circuit boiler of Ukrainian origin, which has everything you need to ensure stable heating of rooms up to 300 square meters. Actually, its main task ATON Atmo 30E performs beyond all praise - the absence of a second circuit for heating water allowed the Ukrainian masters to pay more attention and money to improve and fine-tune the heating function.

For normal operation, the boiler requires 3.3 cubic meters of gas per hour. This is quite a lot (especially for the budget model), but almost all the energy from the combustion of fossil fuels (unit efficiency is 90%) is converted into thermal energy, which, in combination with 30 kW of power, is poured into such a vast heated area.

In general, the model feels the presence of the principle of economy: the designer cut off almost all the "civilized" functions, leaving the boiler only the most necessary - a thermometer, gas control and an overheat protection thermostat. Such a move 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

Lemax Premium-25B is an inexpensive convection-type gas floor boiler. Produced in Taganrog. Able to effectively heat a house up to 250 square meters. m. with an efficiency of 90%. The low price of the device due to the steel structure of the heat exchanger. This material is more susceptible to corrosion, rather than copper and cast iron heat exchangers. However, the developer has provided a special heat-insulating coating with inhibitors, which should significantly reduce the corrosion of the heat exchanger.

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 a higher reliability and efficiency compared with devices on 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 boilers.

It should be noted that the boiler "Lemax" is designed for an open heating system, so when you buy it in the house should be provided a chimney for the output of combustion products.

Most user reviews speak of Lemax’s “indestructibility” and near-silent operation. This is an economical and trouble-free boiler at an affordable price, with a manufacturer's warranty for 3 years. One of the best deals in the budget segment.

The best floor gas boilers: price - quality

Here are the most optimal in terms of price and quality floor gas boilers. The most popular aggregates among buyers.

3 Buderus Logano G124 WS-32

The “Logano” line includes 4 standard sizes (from 20 to 32 kW) of low-temperature boilers, which are considered to be more profitable and safe in comparison with high-temperature boilers. In addition, low temperatures in the heating system create the most comfortable conditions for a person, while eliminating strong temperature differences in an apartment or a private cottage. The unit can be built into the heating system with the help of warm floors, and if the heat losses of the house are too high, it is possible to supplement it with radiators.

Additional heat savings contribute to the special design of a cast iron heat exchanger and heat insulation with a thickness of 80 mm. So that buyers could individually arrange the heating device, the company offers an extensive selection of additional parts and components, I must say, very expensive. For example, the AW 50.2-Kombi flue gas monitoring system is proposed to be bought for almost 9.5 thousand rubles, while for the floor-standing water tank, the Logalux SU will have to pay at least 50 thousand rubles. Nevertheless, consumers are satisfied with the economy, ease of management and durability of the model and recommend it for purchase.

2 Navien GA 23KN

In June last year, Navien Rus LLC was awarded the prize “Company of the Year” in the nomination “The Best Supplier of Engineering Equipment”.

In addition, over the past 4 years, the brand has gained 46.6% of the vote and repeatedly confirmed the title of “Brand No. 1” in the category “Boilers for heating”. What is remarkable about its products, that they vote for it not only with words, but also with a wallet?

In the first place, buyers are attracted by the very reasonable price for the unit, one appearance of which speaks of the unsurpassed quality that is characteristic of South Korean technology. They are not disappointed even after becoming acquainted with the technical characteristics, in particular, the presence of the 2nd circuit, the closed combustion chamber and the electronic control system with a remote control in the kit. Despite its “overseas” origin, the model is fully adapted to Russian conditions of operation and is designed to operate at a minimum pressure of gas and water supply - 4 mbar and 0.1 bar, respectively.

1 Baxi SLIM 2.300 Fi

If you are looking for a high-quality and modern gas boiler from a proven manufacturer, then Baxi SLIM 2.300 Fi is one of the 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 save on quality.

Double-circuit "Baxi" is able to heat a cottage up to 300 square meters. m. with an efficiency of 90%. It can work in a closed heating system due to the built-in circulation pump. The built-in expansion tank will maintain the optimum pressure in the heating system, taking excess when heated and filling up losses during cooling of the coolant. Baxi SLIM 2.300 Fi - one of the best boilers for the operation of a heated floor.

The material of the primary heat exchanger here is the best - cast iron. As you know, cast iron is resistant to corrosion, durable and reliable. Additional features worth noting air vent, safety valve and protection against blocking the pump.

Baxi SLIM 2.300 Fi is one of the best selling floor gas boilers in the middle and highest price segment.

The best wall mounted gas boilers condensing principle of operation

During operation of the gas boiler, condensate forms, which can be used to generate thermal energy. What happens in the boilers of the condensation principle of operation, where the 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 can save up to 20% of the cost of paying for gas. Thus, the efficiency of a conventional convection boiler is on average 92%, while the condensing boiler is able to work with an efficiency of 109%. True, the purchase of a condensation model will be much more expensive than a convection model, and perhaps such a decision would be justified when heating sufficient areas.

Below we suggest to get acquainted with the rating of the best condensing gas boilers of wall and floor types.

3 Baxi POWER HT 1.450

Distinctive characteristics of the model are high power rates of 45 kW, efficiency of 107.5% and the ability to save 100% of power when the inlet pressure drops to 5 mbar. The device implements all modern methods of protection, including protection against freezing, overheating, as well as gas control and autodiagnostics system. The built-in microprocessor constantly monitors the status of the sensors and in case of abnormal situations (for example, a drop in water pressure, overheating or shutting off the gas supply) automatically turns off the boiler. It is also worth noting the presence of auto ignition, air vent and the ability to connect a heated floor.

Baxi POWER HT 1.450 is one of the most reliable premium floor boilers. The obvious disadvantages of the device include only the high price.

2 Baxi Duo-tec Compact 1.24

Baxi Duo-tec Compact 1.24 is one of the most affordable condensing gas boilers. Despite the low price, the power of the device is 24 kW with an efficiency of 105.7%. This is a great model for installation in a country cottage or cottage, as the boiler can operate on liquefied gas with a minimum consumption of 1.92 kg / h. If desired, Baxi Duo-tec Compact 1.24 can be connected to the system underfloor heating. The built-in expansion tank will compensate for the expansion of the coolant. The Duo-tec Compact series is easy to install, easy to use and able to adapt to the quality of the gas. Work 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 condensing

In Europe, traditional boilers are almost never used - they have been supplanted by condensing units like the Protherm “Lynx”.Models of this line have been manufactured since 2002 and are still in demand on the market. There are a lot of reasons for popularity: price availability is also here - mounted condensing boilers with similar characteristics from competitors are 1.5 times more expensive, and a rich rig, and even now actual design.

The system of forced removal of products of combustion allows you to mount the device in the premises in the absence of a chimney. Fuel consumption is 3.2 cu. m / h and provides savings of about 20-30% compared with convection devices. Thanks to two preset modes and an automatic control system with an electronic display, it is easy to set the desired temperature in a private house. Additionally, the developers have provided the ability to connect an external controller. Users do not complain of any failures, which allows us to judge the high reliability of the Lynx.

The best double boilers

When choosing a double-circuit boiler, as well as a single-circuit boiler, special attention should be paid to power. If the residents of the house plan to take a bath often, the minimum power of the equipment should be at least 18 kW, if the priority of the shower, then installing a less powerful unit - from 10 kW. Before buying, it is advisable to check whether the manufacturer has not been stingy with the circulating pump, safety valve, diaphragm expansion tank and fittings included.

3 Bosch Gaz 6000 W WBN 6000-18 С

Its plate heat exchanger is designed so that the 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 the quality of water.

Among other advantages of equipment for heating should be noted the minimum noise - the sound of a working boiler, many users compare with the noise of a computer or refrigerator. Profitability - one more counter "Bosch". It is proposed to provide it with the inclusion of the “Eco” mode, which provides for the heating of water only during its selection. If the most flexible automatic adjustment is required, 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

The Ariston CARES series is the most compact gas boilers in traditional design and with wall mounting. 15-kilowatt is designed for installation in the heating systems of small private houses, villas and apartments, in the limited space of which its dimensions - 400x700x319 mm - take root very well. And by the way, setting up the unit allows you to set the temperature of the heating circuit with an accuracy of 1 °, thereby ensuring an ideal microclimate in a small room.

1 Rinnai RB-207RMF

The Japanese are not in vain as technofriks - even the gas boiler Rinnai RB-207RMF they managed to fill with the most modern electronics. What makes it unique is, first of all, the algorithm for automatically maintaining the optimal ratio of the gas-air mixture in the working chamber. The process is controlled by the "brain" with touch sensors. This achieves an unprecedentedly wide range of output power - from 17 to 100% and, as a consequence, reducing gas consumption and increasing the service life of the primary heat exchanger.

You can control the model from the “Standard” modification console (supplied in the basic package), “Deluxe” or Wi-Fi. With it, you can program the individual mode of heating and hot water, which will be maintained in automatic mode, depending on the performance of sensors outside and inside the building. Changes in settings are duplicated by voice navigator. Two microprocessors are immediately responsible for security, controlling and correcting each other's work. This is not a boiler, but a space rocket, not otherwise!
