The perfect auxiliary boiler
The HDG R15 is the ideal complement to an existing oil, gas or even pellet boiler. The HDG R is also used with heat pumps or in combination with a thermal solar system in low energy housing.
This brings economic advantages and additional security.
As the HDG R15 is an auxiliary boiler, the running time is designed for 800 operating hours per year. A maximum of 30 percent hardwood is recommended for the fuel. Otherwise, this will result in greater wear to the boiler.
