Abstract (en)
[origin: EP0223016A2] The heat-conveying medium in this connection contains demineralised water, as a result of which it is possible to leave the heat-conveying medium in the heating circuit practically without limitation. This heating circuit has, for example, a basic element (1) which has two legs (2, 3) standing perpendicularly to one another, which are each provided with at least one connection (12, 14) for one or more heat exchangers (13). The basic element (1) is at the same time connected to a heat pump (10) (Fig. 1). <IMAGE>
