Claims

[Scope of utility model registration request]

(1) A water storage tank that stores supplied water, a heat collector that is placed above the water storage tank and heats the supplied water using solar heat, and a water storage tank that is arranged so that the water level is always higher than the water level of the water storage tank. A replenishment tank disposed at an intermediate height between the water storage tank and the heat collector, and an auxiliary pump provided midway between the replenishment tank and the bottom of the water storage tank to transfer water from the water storage tank to the replenishment tank. A replenishment pipe for pumping up water, an outbound circulation pipe section that connects the replenishment tank and the heat collector and guides the water in the replenishment tank to the heat collector, and an end portion on the water storage tank side that is always lower than the water level of the replenishment tank. a circulation pipe return section that connects the heat collector and the water storage tank and returns water heated by the heat collector to the water storage tank; A solar water heater comprising: a water level sensor that detects water level and gives an operation command and a stop command to the replenishment pump.

(2) The outgoing circulation pipe section is provided with a check valve at the end facing the auxiliary tank, and is connected to the water storage tank by an auxiliary pipe branching from near this end, and connected to the water storage tank in the middle of the auxiliary pipe. Pumping water from the water storage tank to the circulation pipe outgoing section, the heat collector, and the circulation pipe returning section using the provided pump; 1. The solar water heater according to claim 1, wherein the solar water heater is configured to provide an initial state of siphon operation by the circulation pipe outward path section, the heat collector, and the circulation pipe return path section.
