PURPOSE:To obtain clean hot-water, eliminate a faulty water stop and secure a sufficient hot-water supply pressure by a method wherein a heat collector and a tank are connected so as to allow for the circulation of a heat medium and both ends of a heat exchanging pipe accommodated in the tank are connected with a feed water pipe and a hot-water feed pipe, respectively. CONSTITUTION:Both ends 4a, 4b of the heat exchanging pipe 4 in the tank 1 are connected to the feed water pipe 9 and the hot-water feed pipe 10. When the heat collector 2 is subjected to the sunshine, the heat medium 5 is circulated by a thermo-siphon between the heat collector 2 and the tank 1 through connecting ports 7, 8 and the temperature of the heat medium in the tank 1 increases from the upper part of the tank 1. When a feed water cock 11 is opened and a hot- water delivery cock 12 is opened successively upon supplying hot-water, the hot- water which has been heat-exchanged in the tank 1 may be supplied. The adjustment of hot-water temperature is effected by changing the amount of feed hot- water through adjusting the feed water cock 11 or the hot-water supply cock 12. |
