Some proposals have been made to do this (for example, in 1983
(Refer to Publication No. 1736) However, with this type of equipment, water remains in the heat collector and piping even when heat cannot be collected, such as at night, and there is a risk that this water may freeze during severe cold weather and damage the heat collection circuit. Tips (c) Purpose of the Invention This invention was made in view of the above-mentioned prior art, and uses one pump to circulate water in a heat collection circuit (heat collection operation).
In addition to supplying pressurized hot water through hot water pipes, when the heat collection operation is stopped, the water from the heat collection circuit can be drained.
The porpose is to do.

At this time, the relay coil (4) is energized, the relay switch (411) is closed, and the relay switch (412) is opened.
operation to continue pressurized hot water supply. In addition, when the relay switch (412) is opened, the relay coil (4) is de-energized regardless of the heat collection switch (401), and in order to open the relay switches (422) and (423), the first on-off valve ( 1 is closed, and the second on-off valve (c) is opened. Therefore, even if the pump unit operates during hot water supply, circulation in the heat collection circuit C1O is not performed, and the full output of the pump (17) is used for hot water supply. At the same time, water is drained from the heat collecting circuit (2) in the same way as when the heat collecting operation is stopped.

If the pump (17) is open, the pump (17) is stopped. In addition, when a heat collection command is issued with the heat collection switch (401,) closed, the pump 07) continues to operate, the $1 on-off valve (I ladder is open, and the second on-off valve (2 mark is closed). Heat collection operation is performed.

る太陽熱利用給湯装置っ(1) A heat storage tank that is open to the atmosphere, a heat collector installed above the heat storage tank, a water column pipe that connects the water outlet of the heat storage tank and the water inlet of the heat collector, and a water column that connects the water outlet of the heat storage tank and the water inlet of the heat collector. A heat collection circuit is formed by a water return pipe that connects the outlet and the water return port of the heat storage tank, and a water supply pipe and hot water supply q are connected to this heat collection circuit, and a pump is connected to the water column pipe on the heat storage tank side, Normally closed type first opening/closing means are installed on the collector side, and a hot water pipe is connected to the water column pipe between these pumps and the first opening/closing means, so that the water between the first opening/closing means and the collector is connected. The water column pipe between the inlet and the water drain valve is connected to the heat storage tank, and the water column pipe is equipped with a normally open type second opening/closing means,
The first opening/closing means is opened only when a heat collection command is issued, excluding the time of hot water supply, and the second opening/closing means is opened.
A solar water heating system characterized in that the opening/closing means is closed and a control device is provided to operate the pump during hot water supply or when a heat collection command is issued.
