蛇口２８より出湯する。In this solar heat hot water supply system, the heat medium in the heat collector 21 heated by solar heat is supplied to the heat exchanger 24 by the heat collection pump 23 through the heat medium circulation pipe 22. As a result, the water in the hot water tank 24 is heated. Further, when the heated hot water in the hot water storage tank 24 is opened from the faucet 28 provided at the end of the hot water supply pipe 27, the hot water is automatically discharged from the faucet 28 due to the water pressure supplied through the water supply pipe 26.

水の熱交換は貯湯タンク内の比較的上部のみで行われる
ため、短時間で高温水が得られる。With the above configuration, heat exchange between the heating medium and the water in the hot water storage tank is performed only at a relatively upper portion of the hot water storage tank, so high temperature water can be obtained in a short time.

湯温低下等を解消することができるものである。Further, by circulating and discharging the high temperature water in the upper part of the hot water storage tank to the lower part of the hot water storage tank, the entire water in the hot water storage tank can be heated. Furthermore, the discharge direction variable device installed in the hot water discharge section at the bottom of the hot water storage tank is
(2) The amount of heated water in the hot water storage tank can be varied. These effects eliminate problems with conventional solar hot water storage systems, such as poor water temperature build-up, poor temperature rise during low solar radiation, and a drop in hot water temperature due to hot water discharge during heat collection operation. It is something that can be done.

Ｃのごとくさらにｆ〃くしたりできるものである。In this case, since the amount of water to be heated is small, the temperature of the water in this area rises quickly. Next, the hot water circulation pump 7 is operated to discharge the hot water in the upper part of the hot water tank 4 through the hot water circulation circuit 6 from the hot water discharge part 6a in the lower part of the hot water storage tank 4. The water below vessel 6 will also be heated. Here, a discharge direction variable device 8 provided at a hot water discharge portion 6a of the hot water circulation circuit 6 to the hot water storage tank 4
By operating this, the amount of heated water in the hot water storage tank 24 can be increased or decreased, as shown in FIG.
