The best gas boilers with a boiler

The BAXI NUOVA Duo-Tec 24 gas boiler is capable of servicing heating and hot water supply circuits overnight. The model is intended for wall mounting and is designed for residential areas of up to 180 m².

The device uses the automatic gas control system GAC and a burner with full preliminary mixing of the gas-air mixture. Its power modulation coefficient is 1:7, due to which the boiler operation can be adjusted as flexibly as possible. The boiler burner is made of stainless steel, as is the heat exchanger.

The boiler supports operation in both traditional heating circuits and systems with heated floors. The main thing is that the design of the model provides for the presence of a 45-liter storage tank for hot water - users will always have a solid supply of heated water at hand so that they can calmly take a shower or fill a bath.

In the "full blast" mode, the boiler consumes gas in the volume of 2.61 m³/h - we have a truly economical solution that allows you to reduce bills for the use of "blue fuel". In addition, the boiler has an energy-saving circulation pump with frequency regulation. BAXI NUOVA Duo-Tec 24 will serve as a profitable investment in providing a large home with heat and hot water.

The Buderus Logamax plus GB172-24 T50 boiler is a wall-mounted unit. It is turbocharged (with a closed combustion chamber), so air is taken in not from the room, but from outside. This boiler is condensing. Therefore, it has a high efficiency (109%) and a corresponding energy efficiency class - "A" ratings for both parameters (water heating and room heating).

The boiler volume is small (48 liters). But this does not affect the comfort for users too much, because this boiler has good performance (up to 14 liters of hot water per minute). The burner power can vary from 27% to 100%, so the device confidently operates in the entire range of operating powers (from 7.3 kW to a maximum of 24 kW), adjusting to the current load. It can also be used in heating systems such as "warm floor". The heat exchanger is specially designed for "hard" water with a high salt content. Therefore, this boiler can be safely used in Eastern European countries, where the quality of water treatment at water utilities is traditionally low.

Heating equipment Buderus does not need a special introduction, because it is one of the most famous brands. Although Buderus boilers are usually 20 - 30 percent more expensive than similar devices from other manufacturers, they have many advantages. These include: an excellent reputation of the brand, a wide service network in our country, availability of spare parts and a large selection of automation. Therefore, if you are looking for an economical double-circuit gas boiler for a house or apartment up to 192 m2, then Buderus Logamax plus GB172-24 T50 is a good choice.

Italian heating boilers BAXI are in demand among the widest possible audience. They are characterized by reliability and safety of operation, which is confirmed by the example of the NUVOLA Platinum HT 24 GA model.

The device belongs to the segment of double-circuit boilers for heating and hot water preparation. Moreover, the model scheme includes a built-in boiler with a volume of 45 l with a soluble magnesium anode. Both the primary and secondary heat exchangers of the device are made of stainless steel. The temperature in the boiler coolant circuit can be maintained in the range of 25 °C - 85 °C, and it heats water in the range from 35 °C to 60 °C.

The model maintains its operating capacity even at low gas pressure in the main line. In general, its operation can be fully automated - the boiler is supplied with a THINK remote control unit as standard. At the same time, this module functions as a room thermostat, a schedule programmer for heating and hot water supply circuits. It is also possible to connect weather-dependent automation to the control unit.

The BAXI NUVOLA Platinum HT 24 GA is equipped with a gas adaptive control system GAC, which provides fully automatic combustion control. The boiler circulation pump with full modulation is characterized by high efficiency with reduced energy consumption. Finally, the model provides 8 systems of protection against all sorts of problems: gas pressure drop, flame extinction, water overheating, lack of draft, power outage, water circulation failure, coolant freezing, antibacterial protection.

The Bosch Condens GC5300i WM 24/100S double-circuit gas boiler is ideal for organizing heating and hot water supply in a private house with an area of about 190 m², in which a family of 3-4 people lives. Thanks to the closed (turbocharged) combustion chamber, it does not require connection to an exhaust chimney - this gives more freedom when choosing the location of the equipment installation (however, it is worth considering that due to the large weight of 115 kg, only floor installation of the boiler is allowed).

This boiler operates on a condensing principle. Therefore, it is characterized by high efficiency and economical gas consumption. The modulating burner, which automatically regulates its heat output in the range from 10% to 100%, depending on the current heat needs, also contributes to savings. The wide range of burner modulation allows for flexible and precise adjustment of the liquid temperature in the heating circuits (from 30 °C to 82 °C) and water supply (from 40 °C to 60 °C). The high boiler performance (up to 22.9 l/min) and the presence of the "hot start" function(when you open the tap, hot water flows immediately, without delays) deserve special praise. In addition, the boiler stores a solid supply of heated water in the built-in storage boiler, which holds 100 liters of liquid.

It is interesting to note that the Bosch Condens GC5300i WM 24/100S boiler is perfectly “adapted” to automation, as well as integration into “smart home” systems (but this will require additional investments in automation or thermostats). There is even the ability to control heating via an application on a smartphone (using the Bosch EasyControl CT 200 regulator) or a web browser (when connecting the boiler via the MB LAN2 communication module). This opens up wide opportunities for those who want not only to reduce heating and hot water costs, but also to ensure maximum comfort.

Heating boilers Vaillant are not a cheap pleasure. However, these are truly premium products. The dual-circuit condensing model VSC 266/4-5 150 from the ecoCOMPACT line fits perfectly into this segment.

The device is made in a floor form factor with dimensions of the case 1640x599x693 mm and a weight of about 128 kg. Visually, it resembles a classic two-chamber refrigerator, but the model has completely different tasks. Vaillant ecoCOMPACT VSC 266/4-5 150 is used in radiator and panel-radiant heating systems, as well as in hot water supply circuits.

The material of the main and secondary plate heat exchangers of the boiler is stainless steel. Additionally, the design has a storage water heater with layered heating with a volume of as much as 150 liters. The hot water in such a tank is definitely enough for the needs of a large family of 5-6 people. When operating in the water heating mode, the boiler can switch to the high-power Aqua-Power-Plus mode.

Vaillant ecoCOMPACT VSC 266/4-5 150 is equipped with a burner with automatic regulation of the gas/air ratio, a circulation pump with frequency regulation, electronic ignition and a combustion control system. In addition, the model has an eBUS communication bus for integration with various smart sensors.
