成績係数を向上させることができなかった。Conventional water heaters using heat pumps use a hot water storage method, unlike water heaters that use combustion heat from gas, kerosene, or the like. In this case, hot water pipes are installed from the hot water tank to the kitchen, washroom, bathtub, etc., and hot water from the same tank is supplied through the hot water pipes and mixed with tap water to maintain the appropriate temperature for each purpose. It is practiced to pour out hot water. The main problems with this conventional method are: - The piping from the hot water storage tank to the hot water tap is long, so there is a time delay between when the tap is opened and the hot water is tapped. of hot water is pumped in, so when the tap is closed after hot water is dispensed, the hot water in the long piping system cools and turns into water, resulting in a large amount of heat loss in the piping system, especially in applications where a small amount of hot water is dispensed frequently in the kitchen or bathroom. Furthermore, ■ Since the temperature of the hot water storage tank is always set constant regardless of the application, the condensation temperature of the refrigerant is also determined accordingly, making it impossible to improve the coefficient of performance of the heat pump by lowering the condensation temperature.

To provide a hot water heater that saves energy and shortens hot water start time.
