Compactness The boilers have small dimensions.measures with excellent characteristics, the use of stainless steel allows to extend the life of the boiler for a very long time, while improving its thermal characteristics and efficiency.

Simplicity and convenience
The boiler design is simple, but ensures efficient operation and easy control. The control panel can be used to set operating modes by timer, by water temperature in the heating system or by air temperature in the room. The “absence” function allows you to save fuel, while preventing the heating system from freezing.

Safety:
Combustion control unit
Automatically stops the boiler if for some reason combustion does not occur, fuel (gas, liquid fuel) is not supplied)

Power Failure Protection Unit
If the power supply in the network disappears, the boiler automatically stops working; when the power supply is restored, the boiler also automatically returns to working condition.

Overheating protection unit
If there is no water in the heating system, or if the control panel breaks down during boiler operation, the temperature increases sharply. In this case, overheating protection is triggered, protecting the boiler from destruction

Freeze protection
During the cold season, the boiler automatically turns on the circulation pump and burner to prevent the heating system from freezing.

Fan protection block
If the fan breaks down, the pressure in the chimney surges, or the chimney becomes clogged, the boiler automatically stops working.

Low water level protection
When the water level in the boiler drops below the permissible level, the boiler stops working.
