How people in Germany install heating equipment in their homes
The rooftop solar collector system is mainly used to produce heat, together with other heat boiler systems, for indoor heating and domestic hot water in winter.
Zusatzheizung (auxiliary heating)
The solar collector system is installed on the roof, the combustion furnace is installed indoors, and the "air energy heat pump" system is also installed. The three systems are combined in the "heat exchange hot water storage tank" and the heat generated is used to provide indoor heating and domestic hot water (shower and tub) in winter.
The solar collector system is installed on the roof, and the gas fireplace is installed indoors. The two systems are combined in a "heat exchange hot water storage tank" and the heat generated is used for indoor heating in winter.

Erdsonde (Erdwärmesonde, geothermal probe); Wärme-pumpe (heat pump); Heiz-wasser speicher (heating hot water storage tank); Trink-wasser speicher (domestic hot water storage tank);
The ground source heat pump system is used to produce heat, together with the rooftop solar collector system to produce heat, which is used for indoor heating and providing domestic hot water in winter.
Heat is produced using a boiler system burning wood pellet fuel, together with a rooftop solar collector system to produce heat for integrated use for indoor heating and providing domestic hot water in winter.
With such a complete house diagram it is clear that the Germans are using the roof to install 2 systems (photovoltaic solar panel power system + vacuum heat pipe solar collector system) to accommodate the heating and domestic hot water for the family life in winter.
