ね備えるという効果を有するものである。J: By using the following configuration, when the frosting state of the evaporator due to a drop in outside temperature is detected and the heat pump starts defrosting operation, the auxiliary heater is energized, and both the heat pump and the auxiliary heater are turned on. Since the water in the heat storage tank is boiled, it is possible to sufficiently boil water even during the limited time of late-night power zone, and it is possible to solve the problem of insufficient amount of hot water due to unboiled water. In addition, since it is used in combination with a tomato pump for boiling, the power consumption of the auxiliary heater can be reduced to 1/2 of that of conventional heaters (compared to our company), which also has the effect of saving labor.
