SANITARY OPERATION OF A HOT WATER HEAT PUMP

摘要

A method of sanitizing pipes, etc. In a hot water supply system includes the steps of normally heating water by driving water form a water storage tank, into a heat exchanger. Typically, a water pump is stopped once the water storage tank receives a particular percentage of hot water. However, when a sanitation mode is desired, the pump is not stopped, such that the water tank becomes all, or almost all, hot water. The hot water is then delivered to the pump, and from the pump to the heat exchanger, This hot water is thus operable to sanitize pipes and the pump.
