PURPOSE:To make it possible to collect heat and to supply hot water by a single pump to thereby reduce the manufacturing cost of the titled hot water feeder by a method wherein water discharged from the pump is injected from a nozzle of a water injecting pump so that the water in a heat accumulation tank is sucked and circulated through a heat collector. CONSTITUTION:When the hot water pressure pump 11 is operated at the time of heat collection in a condition in which a valve 12 is opened and a hot water supply faucet 10 is closed, the water in the heat accumulation tank 2 is sucked into a hot water supply pipe 9 and then injected from the nozzle 8 of the water injecting pump 7. As a result, the water in the tank 2 is sucked from the lower part of the tank 2 due to an ejector effect and after being mixed with the water injected from the nozzle 8, it is supplied to the solar heat collector 1 where it is heated to an elevated temperature and returned to the upper part of the tank 2. Thus, with the repetition of the above operation, the hot water is stored in the tank 2 from the upper part thereof. On the other hand, when the hot water supply faucet 10 is opened at the time of supplying the hot water, the hot water in the tank 2 is supplied under pressure to the faucet 10. |
