Abstract (en)
[origin: EP0931988A2] The primary heat exchanger (7) is part of a primary circuit (10,11,12) incorporating at least one hot water heating body and a circulating pump (5). The secondary heat exchanger (3) is part of a secondary circuit (13) incorporating at least one hot water tap point. When required, the secondary heat exchanger can be connected to the primary circuit via a connecting conduit (9) between the forward flow (11) and back flow (12) of the primary circuit. The secondary heat exchanger can be bridged over by a bypass conduit (8) and a valve (2) is provided for the connecting conduit (9), by means of which the throughflow can be interrupted or at least reduced to a leak flow so that the secondary heat exchanger is uncoupled from the primary circuit.
