A floor-standing gas boiler with an open combustion chamber that does not require connection to the power grid and can operate in heating systems with natural circulation of the coolant. A capacity of 12.5 kW is enough to heat a house with an area of up to 94 m² and heat water for domestic needs at a rate of up to 5 l/min. The water temperature in the heating circuit can be adjusted in the range from 50 °C to 90 °C.

Gas consumption when operating in maximum power mode does not exceed 1.39 m³/h. The ATON Atmo 12.5EB boiler is equipped with Italian EUROSIT gas automation and a Polidoro gas burner. The design of the equipment provides for the possibility of connecting a programmer and thermostats. The boiler circuit includes devices that ensure safety in case of overheating of water in the heating circuit, lack of draft in the chimney, flame extinction on the pilot burner or pressure drop in the gas main.

ATON Atmo 12.5EB 12.5 kW price graph

If you plan to change the boiler every eight years, this is a great choice.
 15 November 2016 
The boiler is simple, the dimensions are acceptable, the installation is not complicated. The automation is imported.
Advantage - low price.
The only detail made in Ukraine is a heat exchanger. That bish is the water tank itself. Here it is in the 8th year of operation and flowed. The welder who made the repairs said that the thickness of the metal was not more than 2 millimeters. After working for a year after the repair, it dripped again.

With a tight budget, this double-circuit boiler will be an excellent choice.
 28 February 2016 
When I needed an inexpensive gas boiler that did not depend on electricity, I immediately focused on domestic manufacturers. And the company ATON found a number of models completely suitable for my needs. True, the boilers turned out to be on the wall, but on the floor. But, in the end, it turned out even more convenient.
The most important advantage of this device is, of course, the price. It is insanely difficult to find a full-fledged double-circuit boiler for such money, and it is simply impossible among imported models. The boiler is completely non-volatile. In my case, this was a prerequisite, because. overhead power lines in the area where I live break and short out with frightening regularity. Despite the simplicity of design, the boiler consumes gas quite economically. Last but not least, this is achieved through the use of Polidoro gas burners. It produces enough heat for my 96 squares, it’s also a sin to complain about hot water - the pressure is sufficient, the temperature too. Installed gas automation Eurosit, which means that the safety of the boiler is at the proper level. Due to the fact that all automation works on mechanical principles, the boiler turned out to be reliable. Yes, he does not have cunning software control and fashionable modulated burners, but he does his job perfectly.
During installation, there were problems with the contamination of the threads at the input-output of the coolant. After cleaning everything went well. For such power, the size and weight are too big. Could have been more compact.
