Abstract:
PROBLEM TO BE SOLVED: To provide a hot water storage type water heater capable of reducing a heat loss of expanded water.SOLUTION: The hot water storage type water heater has a hot water storage operation mode heating water in a hot water storage tank 3 by a heat pump unit 1 to store hot water in the hot water storage tank 3. The hot water storage type water heater includes: a high-temperature discharge path 6 constituted of a high-temperature pipe 4 taking high-temperature hot water or air from an upper part of the hot water storage tank 3, and an on-off valve 5 disposed along the high-temperature pipe 4; a low-temperature discharge path 8 constituted of a low-temperature pipe 7 for taking low-temperature water from a lower part of the hot water storage tank 3; a pressure relief valve 9 disposed to communicate with the high-temperature discharge path 6 and a low-temperature discharge path 8. In the hot water storage operation mode, a time for opening the on-off valve 5 is provided, the expanded water generated in the hot water storage tank 3 is discharged as the low-temperature water to the outside of the hot water storage tank 3 when the on-off valve 5 is closed, and the air in the hot water storage tank 3 can be discharged to the outside when the on-off valve 5 is opened.
