PURPOSE:To permit the stable operations of a heat pump and a circulating pump and obtain the heat pump device for supplying hot-water capable of being operated with good performance coefficient by operating the heat pump and the circulating pump after the level of water in a hot-water reserving tank has arrived at a given level. CONSTITUTION:When a starting switch is thrown, the solenoid valve 6 and a motor valve 7 are opened fully and city water flows into the suction side pipeline 3b1 of pipeline 3b from a city water inlet port 5 through a water supplementing pipeline 8. When the level of water in the hot-water reserving tank 2 has exceeded a water level C by said operations, the heat pump 1 and the circulating pump 4 are conducted and this condition is continued until the level in the same tank 2 arrives at the fully level A while the solenoid valve 6 is closed when the level has arrived at the fully level A. Thereafter, normal operation is effected and the opening degree of the motor valve 7 is regulated so that the water temperature at the outlet section B of the heat pump 1 become a set value of 55 deg.C, for example, and the heat pump 1 is operated so that the water temperature in the hot-water reserving tank 2 become a set value of 53 deg.C, for example. |
