Claims

[Scope of Claim for Utility Model Registration] ■ External circulation channel 5 extending between the lower and upper parts of the hot water storage tank 3
is formed, and two types of heat exchangers 6 and 7 with different heating temperature levels are arranged in this circulation flow path 5 with the one with a higher heating temperature level located on the downstream side in the flow direction. , a hot water supply system in which a valve 8 that is automatically and reversibly opened when the water temperature reaches a set value is interposed on the downstream side of the high temperature level heat exchanger 6 in the circulation flow path 5 in the flow direction. In the apparatus, a valve 9 that automatically and reversibly opens at a set temperature lower than the opening set temperature of the valve 8 is provided in a flow path portion of the circulation flow path 5 located between the isothermal exchangers 6 and 7. A bypass flow path 10 is connected therebetween, and the other end of the bypass flow path 10 is connected to a portion of the circulation flow path 5 on the downstream side of the high temperature side valve 8 in the flow direction or to an upper part of the hot water storage tank 3. water heater. (2) The low temperature level heat exchanger 7 is a condenser of an engine-driven heat pump, and the high temperature level heat exchanger 6 is a heat exchanger for recovering engine exhaust heat. The water heater according to item 0.
