TOP-10 non-volatile gas boilers for heating a private house: a review of models + selection rules

The leader of the Patriot series boiler is the manufacturer Lemax, which works with both natural and forced heating systems. The design is smokeless, so installation is possible not only in a cottage or in a country house, but also in a city apartment. The combustion air is taken in and the combustion products are removed through a coaxial chimney mounted in a wall near the unit.

The heat exchanger is made of 2 mm high-quality steel that meets the requirements of GOST, and is coated with corrosion-resistant enamel on top, protecting the metal from mineral oils and salt solutions. The gas valve and microflame torch are original Italian-made parts.

To create a convection effect, perforation is provided on the front panel. Safety is enhanced by the integrated gas-control system and protection against overheating. Efficiency is 87%, the warranty period is 3 years.

The floor model of the Ukrainian brand ATON fell on the third line of the rating due to a successful combination of technical characteristics and a design understandable to the user. The boiler has enough productivity to heat a room of 160 m², that is, it is suitable for a large cottage or multi-room apartment.

The manufacturer recommends installing the unit near the external wall in order to facilitate the installation of the coaxial chimney necessary to ensure the combustion process. In the room, it is also necessary to create optimal conditions for the operation of the boiler and its maintenance, that is, to establish natural air circulation.

Despite the word “Compact” in the name of the model, it looks bulky in comparison with analogues of other brands. But, unlike the others, it has a small depth.

Top level operation

The third leader with a closed combustion chamber is completed by the third Lemax Patriot model, which has a power of 20 kW. It is intended for the equipment of heating systems of private houses of a large area. The installation method and the principle of smoke removal are the same as for all units of this brand.

The boiler is more bulky than its low-power counterparts, and this must be taken into account during installation. It is recommended to strengthen the installation base, since the equipment weighs 67 kg and finish the adjacent wall with non-combustible materials. It is best to clad the surrounding surfaces with metal sheets.

Like other equipment of the Lemax Patriot series, the boiler is equipped with an POLIDORO injection-type burner and an Italian-made SIT gas valve.

The first place in TOP-5 boilers with an open combustion chamber is occupied by the Leader model with a capacity of 16 kW of the same manufacturer Lemax. In the leading five, 4 out of 5 units belong to this popular brand in Russia. The boiler is designed for heating an area of ​​160 m², that is, it is suitable for heating 1- and 2-storey cottages.

A distinctive feature of the Leader boilers is a cast-iron heat exchanger of Czech manufacture. Thanks to the high-quality 4 mm gray cast iron units manufactured by VIADRUS, maximum heat transfer and anti-corrosion properties are ensured.

The unit provides protection against overheating and gas control is installed, blocking the supply of fuel when the fire is extinguished. A thermometer allows you to control the temperature of the liquid in the circuit, and a pressure gauge allows you to monitor the pressure.

Constant monitoring of the unit is not required. It is possible to switch from natural gas to liquefied gas if there is no chance to connect to a common trunk. Efficiency is 90%, the warranty period is 3 years.

The model has many positive reviews from users who like literally everything - from an understandable, intelligently assembled design to efficient heating and excellent technical data. The model is single-circuit, designed only for space heating. If hot water is also needed, we recommend considering double-circuit gas boilers.

The maximum area that can be heated using a 20-kilowatt boiler is 200 m² - this is a large cottage or industrial area. A powerful unit requires more fuel - 2.4 m³ / h, however, it belongs to economical models.

Thanks to the cylindrical heat exchanger, the equipment copes with work in closed heating systems, the pressure of which reaches 3 atm.

Care of all elements of the boiler is carried out manually, having previously removed the lining. Gas burner and safety features made in Italy. Efficiency is 90%, the warranty period is 3 years.

A relatively small model of medium power for the equipment of heating systems in country houses, as well as non-residential premises for various purposes. A good solution for stand-alone networks connected to natural gas. Equipped with a single-stage injection burner. Not suitable for other fuels, such as propane.

Thanks to the pressure and temperature indicator, it is easy to control the heating process and make adjustments in time. Like other boilers, protection against overheating and flame attenuation is provided. The steel heat exchanger has good thermal conductivity and quickly heats water.

The dimensions are compact, the design is minimalistic. Thanks to its small width and depth, it is much easier to install the unit than more bulky and powerful models.

Maintenance of the boiler is not difficult: you need to clean the burner in time and carry out a routine inspection of the automatic components. The efficiency is 92.5%, the warranty period is 2 years.

Another “cast-iron” model of Russian production, the most powerful of the Leader brand aggregates presented in the rating. Suitable for open and closed heating systems. A heat exchanger with walls of 4 mm made of gray cast iron holds heat well, but significantly increases the weight of the unit.

Italian burners and a security system work flawlessly, as confirmed by service center employees. If the boilers from the Leader series get into repair, it is mainly due to the fault of users - due to operational errors.

Not the largest dimensions of the unit are deceptive - it weighs more than other models. This must be taken into account during transportation and installation. Efficiency is 90%, the warranty period is 3 years.

Specifications:

• type - convection;
• contours - one;
• Max. power - 35 kW;
• gas consumption - 4 m³ / h;

• dimensions (w / h / d) - 600/856/520 mm;
• weight - 140 kg.

The unit is designed for heating systems serving areas of up to 350 m². For standard country houses, these are too powerful boilers, but owners of large 2-story cottages are advised to consider this option.

Closes the five units with OKZ is another model from the Leader series, but already with a power of 25 kW. By design and functions, it completely repeats the previous boiler, and differs only in technical characteristics: power, fuel consumption, dimensions, weight. Suitable for heating an area of ​​240 m².

The main advantages still include a cast-iron heat exchanger with walls with a thickness of 4 mm, thoughtful assembly, timely triggered automation. Italian parts fail in rare cases, in general, the system with the boiler works smoothly, almost flawlessly.

Specifications:

• type - convection;
• contours - one;
• Max. power - 25 kW;
