15 best gas boilers
What to look for when choosing a gas boiler
When choosing a gas boiler, you need to rely on the reputation of the company and its breakdown statistics. But there are also some criteria, without which it is simply impossible to find a good device. Let's try to figure out what you need to remember before buying gas equipment:
- Boilers are divided according to the installation method into wall-mounted and floor-standing, so analyze where you have more space;
- The type of boiler - convection and condensing - should be selected depending on the desired price;
- The number of circuits - there are double-circuit and single-circuit boilers - affects whether the boiler can heat water;
- The more the heated power, the better the device will work;
- The type of combustion chamber - closed or open - indicates whether a person can see how the boiler is operating;
- There are different sizes of boilers, so it is important to take into account the area of the room where it will be installed;
- High level safety is literally vital as gas equipment can explode.
The best manufacturers of gas boilers
You can not trust all companies involved in the production of gas boilers. The fact is that low-quality materials or the use of old technologies can negatively affect the durability of the device. But it is quite possible to take a closer look at the products of the following companies:
- BAXI - a powerful European holding that appeared in 2009 and produces household appliances;
- German company Viessmann creates cooling and heating systems for various types of buildings;
- Vaillant - these are licensed equipment from Germany, mainly heating boilers and regulators;
- Protherm develops heating boilers with high efficiency, including gas-fired ones;
- Lemax holds the lead among Russian manufacturers of equipment for temperature control;
- Buderus Is a trade mark that has been producing boilers and other heating devices since 1731.
The best wall-mounted convection gas boilers
Wall-mounted convection models of gas boilers are compact. This is what captivates those who are forced to equip small rooms with heating or simply do not have a place for a device. So, gas wall-mounted boilers can be installed even in non-residential premises of an apartment. It remains to figure out which one to choose.
BAXI ECO-4s 24F 24 kW
Wall-mounted convection gas boiler BAXI ECO-4s 24F 24 kW is assembled in Italy according to European standards, so there is no doubt about the quality of the parts and materials used.

The best single-circuit gas boilers
Single-circuit gas boilers are designed exclusively for heating the coolant in the house. They take up little space, but only heat small areas. So, for a space over three hundred square meters, you will have to look for some kind of alternative model.
Lemax Leader-25 25 kW single-circuit
The single-circuit gas boiler Lemax Leader-25 25 kW has an efficiency of 91%, which cannot be called a bad indicator. It has an open combustion chamber and the recommended installation type is floor standing. The device perfectly takes root both in the kitchen and in the storerooms or other non-residential areas of the apartment.But only a professional can mount it: the weight, excluding accessories and packaging, is 115 kilograms. It is for this reason that the boiler must be installed forever. The Lemax gas boiler operates relatively quietly, which is a valuable feature for such models.

BAXI has built a weather-dependent automation into it, so the room temperature will be set not according to the set algorithms, but depending on the circumstances. At the same time, the heating range is 35-80 degrees Celsius, it is obvious that the spread is very good. It is important to note that the BAXI LUNA-3 240 Fi 25 kW boiler can operate in parallel with the underfloor heating system. This is one of the most flexible and convenient models in this ranking, despite the fact that it is in the last position.
PROS:
- can provide heat up to 188-240 square meters;
- separate heat exchangers;
- economical consumption of gas fuel;
- high DHW performance.
MINUSES:
- objectively high price both in real stores and in the network;

Which gas boiler is better to choose
All boilers sold in online stores or in real retail outlets have a right to exist. At least, because some models are inexpensive, while others cost almost six figures. Therefore, the main advice for choosing a gas boiler is that you need to take one that can safely heat a room of a predetermined area or heat water at the same time. Be sure to check reviews about the fire hazard of the product you are buying and choose only one with a clean reputation. Other favorable parameters are considered only desirable.
