PROBLEM TO BE SOLVED: To improve heating property at starting operation by giving priority to a heating side in distributing compressor capability at the beginning of starting hot water storing operation and heating operation at the same time while sorting refrigerant into both a hot water storage water refrigerant heat exchanger and a heating side water refrigerant heat exchanger. SOLUTION: This heat pump hot water supply heating device comprises a hot water storage side heat pump refrigerant circuit TR, a heating side heat pump refrigerant circuit DR, a hot water storage circuit C2 for circulating hot water in a hot water storage tank 31 for boiling-up, a heating circuit C1 for circulating heating hot water into a heating terminal for heating operation, and a control device S1 for controlling the openings of a hot water storage side flow control valve 27 and a heating side flow control valve 26 to sort the flow of the refrigerant from a compressor into the hot water storage heat pump refrigerant circuit and the heating side heat pump refrigerant circuit. The control device makes the opening of the heating side flow control valve in the heating side heat pump refrigerant circuit greater than the opening of the hot water storage side flow control valve in the hot water storage side heat pump refrigerant circuit at the beginning of starting hot water storing operation and heating operation at the same time.
