Method for room- or building heating under partial use of renewable, volatile electrical energy, involves supplying electrical energy in electro-thermal storage for heating room or building by using controller

摘要

The method involves primarily supplying electrical energy in one or more electro-thermal storage for heating a room or building by using a controller and the secondary supplying the electrical energy into an external power grid. The electro-thermal storage has insufficient cover of the thermal energy demand of the electro-thermal storage, and the heated room or building is supplied or jointly supplied from an external power grid by using the external energy supplied into the room or building via a local generation system.
