A storage reservoir for a domestic hot water supply is divided into an upper stand-by tank, including an auxiliary heating device, from which hot water is drawn and a lower tank which includes a heat exchanger connectable to a solar energy receiving circuit. The separating wall includes two flow orifices communicating between the two tanks which ensures cold water is present at the heat exchanger thus enabling optimum transfer of the energy available from the solar receiver. |
