During the construction of a residential building a completely new concept of an isolated year-round underground storage tank has been developed and implemented. With a volume of 550m ³, it can store enough energy to the building throughout the year to supply heat. Is fed to the memory of a 120m ² solar system. 2 buffer memory with 10000 liters make for hot water treatment. A Notversorgungswärmepumpe supplies in winter if necessary, the required higher hot water temperatures. A photovoltaic system with 3kWp is supplying the power."/>
