When the thermosiphon action is insufficient due to insufficient temperature rise in the heat collection panel, the thermosiphon action is assisted by operating the circulation pump and blocking the reverse flow in the cold water piping by the check valve. Hot water can be supplied with minimum pump drive power. In addition, due to this check valve, it is possible to prevent backflow during normal circulation (at the time of circulation due to thermosyphon action).

Upward water flow is generated. Therefore, the cold water header is smoothly branched to each heat collecting pipe, and the heat collecting pipes are smoothly joined to each other without disturbing the direction.
Therefore, a pump for regulating the direction of the water flow and driving power therefor are unnecessary. In addition, as a result of the cold water header and the hot water header being oriented in the vertical direction, it becomes possible to orient the heat collecting pipes in the horizontal direction, so that it is possible to install the heat collecting device on a veranda or the like where the height in the vertical direction is restricted. It will be possible. Further, in the invention of claim 3, since the communication position with the cold water header is lower than the communication position with the hot water header in each of the plurality of heat collecting pipes, a water flow due to the thermosyphon action also occurs inside each heat collecting pipe. , Therefore, the circulation of water becomes smoother.
