しまうという問題点があった。Further, in the case of the conventional natural circulation type solar water heater, if the amount of hot water discharged from the main body of the solar water heater is larger than the amount of water supplied to the solar water heater at the time of hot water discharge, the water supply cannot keep up with the hot water and air is discharged from the hot water outlet 35. I will inhale. As a result, when air is sucked into the pipe, "air bleeding" occurs and the amount of hot water discharged is extremely reduced, or the hot water itself cannot be discharged unless the air in the pipe is removed by some method. There was a point.
