The boiler can function as the main heat source, especially in houses with good thermal insulation and underfloor heating operating at a low temperature. It may become the best option to choose.

It can also function as a supporting heat source for a solid-fuel boiler, a condensing boiler, a fireplace or even a heat pump in more difficult winter conditions.
