Rating of the best gas boilers for a private house. How to choose the one and only?

Wall-mounted boilers with two circuits, operating on gas fuel, make it possible to provide hot water supply to radiators (one circuit) And taps (second circuit) Houses.

Gas boilers are most often used for heating private houses.

Features of wall-mounted gas boilers for heating a private house

Wall mounting places special demands on the devices:

• compact dimensions;
• light weight;
• easy control;
• modern design.

Often, boilers are mounted on walls not in separate buildings, like floor-standing ones, but directly in utility rooms of houses - for example, in the kitchen.

This is what boilers are made for relatively small in size with a control panel on the frontThe body has a rectangular shape, which allows the device to fit more easily into the interior of the room.

It is possible to maintain functionality with small boiler sizes thanks to the use of electronics and new technologies (for example, condensation).

The meaning of the parameters, which options are reliable

Power — a key parameter that allows the boiler to generate the required amount of heat for heating and hot water supply (DHW).

It is of great importance when choosing a suitable model and is calculated according to the principle 1 kW per 10 sq. m.

But no boiler should operate at maximum capacity, otherwise it will quickly fail. Therefore, when calculating the boiler power parameter, add 20% stock.

That is, for a house with an area of 100 sq. m., a boiler with a capacity of 12 kW.

Camera type affects a whole range of boiler operating characteristics at once. Combustion chamber closed type allows you to install the boiler in a limited space. The main thing is that it is next to the outer wall of the building, through which the coaxial chimney used with a closed chamber is led out.

For combustion chamber open type it will be necessary to install a chimney and provide air flow into the room. Due to the closed system, the closed type has higher productivity and savings than the open type. But the device with a closed chamber is also more expensive.

When choosing a fuel type It is important to note that modern boilers are designed to operate both in nature, and on liquefied gas. But it will be an advantage if there is a gas pipeline at the place of installation of the boiler, since it is cheaper, more convenient and safer. The characteristics of each device indicate what is the fuel consumption when working on natural and liquefied gas. By default, the gas boiler is configured to work on natural gas, so when switching to a liquefied device, you will have to reconfigure it.

Efficiency of a gas boiler — an important parameter in terms of the ratio of operating costs of the device and the results of its work. The optimal efficiency range for wall-mounted boilers can be considered 90-95%. Low efficiency requires more fuel, while high efficiency requires more expensive components for the device, such as copper heat exchangers.

Wall-mounted double-circuit boilers use heat exchangers made of copper and stainless steel. The first transmit heat well, second — more reliable in operation.

There may be both steam and m in the boiler.copper-steel, and steel-steel heat exchangers. One is responsible for the heating circuit, the other for hot water supply.

There are also models of boilers with bithermic copper heat exchangers, the operation of which is organized according to the principle "pipe in pipe".

Hot water supply — an important function of a double-circuit boiler. Therefore, when buying it, it is worth studying such an option in the technical data sheet as the DHW performance. Usually, the parameters indicate at what temperature And How many liters can the boiler heat? For homes where hot water from the taps is used quite frequently, this point plays an important role.

All these parameters must be taken into account in order to effectively use the gas boiler. At the same time, it is worth using its resource sparingly - for example, do not turn it on at maximum power for a long time. In case of regular maintenance (technical inspection once a year) and proper operation, the device can serve reliably for quite a long time - on average up to 15 years. You can choose the right option for a specific building by studying the model rating. In it, boilers are arranged in descending order of efficiency (COP).

Rating of the best models and manufacturers

Below is a rating of the best gas boilers for heating a private home.

Wolf CGG 1K 24

The German-made gas boiler has maximum power 24 kW. It is enough to provide heat to a building with an area of about 200 sq. m. The device is equipped with a closed combustion chamber.

This involves the use of a coaxial chimney.

The use of a copper heat exchanger for the heating circuit and a steel heat exchanger for hot water supply allows for a stable supply of heat from the boiler to the premises and to the hot water taps.

At temperature +35 °C The capacity of the hot water supply is 8.6 l. The device occupies the first line of the rating due to its high efficiency - 93.0%. Other advantages Wolf CGG 1K 24 you can attribute a small weight - 40 kg and noise level 38 dB. The device allows the consumption of natural gasand 2.8 cubic meters per hour and liquefied - 2.1 kg per hour.

Baxi Luna 3 Comfort 240 Fi

Made in Italy, the unit is designed to handle power 25 kWIt is suitable for heating a room with an area of ​​over 200 sq. m. The device has a closed combustion chamber, with which a coaxial chimney is used. The boiler operates two separate heat exchangers: copper and stainless steel.

DHW performance at temperature +35 °C makes up 10.2 l. By efficiency 92.9% Baxi Luna 3 Comfort 240 Fi in second place, but some of its characteristics are higher than those of the leader. For example, the noise level is only 32 dB, and the weight is 38 kgHowever, the device has a slightly higher maximum consumption of natural gas - 2.84 cubic meters per hour, as well as liquefied - 2.12 kg per hour.

Bosch ZWA 24 2K

This device is designed in Germany and manufactured in Turkey. Maximum boiler power 22.00 kWThis is enough to heat the room. about 200 sq. m. The boiler has an open combustion chamber, which requires a chimney and ventilation in the room. A special feature of this model is the bithermic (pipe in pipe) copper heat exchanger, which makes the device more compact.

At temperature +35 °C The performance of the DHW circuit corresponds to 9.8 l. The efficiency reaches 92.0%. According to this indicator Bosch ZWA 24 2K ranks third in the rating.

How to choose the right boiler: reliability of different companies

According to the given indicators, the optimal option for a house with an area of 200 sq. m. could become an Italian boiler Baxi Luna 3 Comfort 240 Fi. It has good efficiency, decent power, low noise level and relatively low weight. Among Russian analogues, perhaps only Lemax PRIME-V24.

Both manufacturers have a warranty period of 24 months. But Baxi boilers are better known for their reliability. There are no difficulties with their maintenance: service centers and partners of the Italians are all over Russia. Therefore, if the budget allows, you can give preference to a foreign manufacturer.
