Abstract

A heating system for a building utilizing a heat pump having a condenser which is driven by an internal combustion engine. The internal combustion engine drives an additional aggregate, such as a brake, for the purpose of generating additional heat which is added to the main heat carrier in the heating network in the building. The circulating system for the additional heat generating aggregate is self-contained and separate from the heating network of the building.
