PROBLEM TO BE SOLVED: To quickly warm up a heater at the initial stage of heating in a hot water supplying heating system with a heat pump. SOLUTION: The hot water supplying heating system is provided with a heat pump 10, a hot water circuit 20 and a controller 40 (control means). The controller 40, receiving the instruction of executing the heating operation of a floor-heating panel 32 (heater), executes a heating initial mode at first. In this mode, the hot water circuit 20 and the heating circuit 30 are operated. Heat is collected from the hot water of the hot water circuit 20 by the heat exchanger 11 of the heat pump 10 and radiated by the floor-heating panel 32. Therefore, the floor-heating panel 32 can be warmed up quickly. Then, the controller 40 switches to a normal heating mode. In this mode, the cooling medium circuit 12 and the heating circuit 30 of the heat pump 10 are operated and a heating medium receives the heat from the cooling medium at the heat exchanger 11 and radiates the heat at the floor-heating panel 32. |
