Abstract (en)

[origin: EP0092864A2] The hot water production system, in particular for domestic use, comprises: a water container connected to a cold water inlet (3) and hot water outlet (5); a water circuit connected to the container in which a circulation pump is disposed; and a heat pump, the condenser of which is in heat transfer relationship with said water circuit. In the water circuit (4) there is disposed a heat exchanger (7) heated by the condenser (8). Temperature control means (TA) are provided, which control the circulation pump (6) and heat pump (9). A temperature-controlled valve (14) controls the amount of water flowing from the water circuit to the container (1).
