12 best floor gas boilers

Heating private houses with gas is the most cost-effective in our country. Therefore, one of the main elements of the heating system becomes a gas boiler. The best option for heating living space with a total area of ​​80-900 square meters. m will install an outdoor heat source. On the market, consumers are offered models of various domestic and foreign manufacturers. They differ not only in price, but also in important technical parameters.

• In terms of functionality, all gas boilers can be divided into single-circuit and double-circuit boilers. The first are used exclusively for space heating. Models with two circuits can not only give heat to the heating system, but also heat the water for the kitchen and bathroom. Despite a number of advantages of boilers with two circuits, experts do not recommend installing them in homes where the bathrooms and kitchens are far removed from the boiler room.
• Gas boilers differ in the way of management. Mechanical models are easier to maintain and repair, and electronic control allows you to achieve maximum comfort with complete non-interference in the work of residents of the house.
• Structurally distinguish condensation and convection boilers. In convection models, the coolant is heated solely by the heat generated during the combustion of the gas. With this classical scheme of obtaining thermal energy, large losses occur. Modern condensation boilers have a much higher efficiency coefficient (KPI). In addition to energy from the combustion of gas, they generate heat from the water vapor that is released during the combustion process. Water vapor is condensed in an additional heat exchanger, which ultimately saves up to 20% of hydrocarbons.

We offer you a selection of the best gas boilers of the floor type, which is compiled on the basis of technical characteristics, cost, customer reviews and expert opinions.

The best gas boilers for heating areas up to 100‒150 square meters. m

Ideally, the power indicator of the unit should be determined on the basis of thermal imaging diagnostics, but in practice it is calculated by the average value, based on the calculation of 1-1.5 kW per square meter. Choosing a gas boiler with high parameters is not worth it - a low load level leads to a decrease in efficiency and increased wear of mechanical parts. This category includes equipment suitable for use in small, up to 100-150 square meters. m., residential and non-residential homes.

3 ATON Atmo 10EVM

In the CIS countries gas is supplied under lower pressure than in Europe; moreover, due to the high degree of wear and tear, accidents often occur on the main lines.With a critical drop in pressure, foreign equipment, calculated at a rate of 20 mbar, begins to work for a third of its capabilities or stops altogether. That is why the residents of small settlements, where this problem is most relevant, prefer to buy inexpensive boilers adapted to local gas supply conditions. These include the ATON Atmo 10EVM, ready to heat a house with a stated power even at 13 mbar.

What else is important, the device does not require connection to the mains and operates in conditions of natural circulation of the coolant in the circuit due to the difference in density of cold and hot water.
