A hot water supply device of a heat pump and a control method thereof are provided to easily check the malfunction of a heater and to reduce the manufacturing cost since it has the simple structure. A hot water supply device of a heat pump comprises a heat pump, a water circulator, a heater inundation temperature sensor(140), and a controller(170). The heat pump comprises a compressor, a water cooling each heat exchanger, an expanding balloon(30), an evaporator. The water circulator includes a pump(90) circulating to the water. The water, whose heat is exchanged with the refrigerant at the water cooling each heat exchanger, passes through a hot water supply piping and a heater(100). The heater inundation temperature sensor senses the temperature of the water passing through the heater. The controller detection of the operation condition of the heater when p the heater and a ump operate according to the temperature sensed by the heater inundation temperature sensor. |
