摘要

Ventilating installation comprises a first circulation (5) containing a heating boiler (1) to convey heat from a primary heat source (2) to a first heat carrier medium and a second circulation (8) containing an air heating register (4) to convey heat from a second heat carrier medium to the air. The first circulation and the second circulation are connected by a heat exchanger (3). Preferred Features: The second heat carrier medium has a melting point lying below the melting point of water and is preferably a glycol-water mixture. A circulating pump (11) is arranged in one or both circulations.
