Implemented: August 2011 / with CCFI 50% co-financing.
System: Thermo|Solar 4 flat TS 300 solar thermal collectors, solar boiler 300 liters, other system elements.
The new solar boiler is connected to the existing boiler, which was recently purchased and is still in very good condition. Collectors also return heat to heated floors at a time when there is no need or insufficient heat for hot water preparation.
The house has gas heating, and to support it, heat is taken from the upper loop (heat exchanger) of the solar boiler.
