Claims

[Scope of Claim for Utility Model Registration] 1. A heating device that includes a heat pump refrigeration device 2 and an electric heater 3 for heating water in a hot water storage tank 1, and within a period of time within which the operation is restricted to not exceed a predetermined power value. In a heat pump water heater that is capable of storing hot water at a predetermined temperature in the hot water storage tank 1, the capacity of the electric heater 3 can be controlled stepwise or steplessly;
A control circuit that controls the operation 2 of the electric heater 3 and the heat pump refrigeration device 2 has a control circuit that controls the water temperature in the hot water storage tank 1 based on the direct temperature rise point that can be raised by the heating operation of the heat pump refrigeration device 2. When the water temperature is low, the heat pump refrigeration system 2 and the electric heater 3 whose capacity has been reduced by capacity control are operated together, and when the water temperature is high (and has not reached the predetermined temperature), the rated capacity of the electric heater 3 is reduced. an operation switching means for performing independent operation according to Calculate each value of the heating capacity per unit time and the rated heating capacity of the electric heater 3, and calculate the time of the individual operation according to the rated capacity of the electric heater 3, and the capacity and operation time of the electric heater during the combined operation. - Calculate and determine the operation start time backwards, and start the combined operation of the electric heater 3 set to the required capacity and the heat pump refrigeration system 2 when the time arrives. A heat pump water heater characterized by: 2. The starting means in the control circuit starts the combined operation upon arrival of the restricted time period, and determines the amount of the 1-top pump refrigeration system 2 during the combined operation based on the total required heating amount. By determining the capacity of the electric heater 3 during combined operation based on the total heating amount and the value obtained by subtracting the total heating amount of the electric heater 3 during independent operation, the limited time period can be utilized to the maximum extent. A heat pump water heater according to claim 1, which is a utility model and which enables efficient heating operation.
