HEAT PUMP TYPE HOT WATER SUPPLY SYSTEM

PROBLEM TO BE SOLVED: To provide a heat pump type hot water supply system configured to miniaturize its hot water storage tank.SOLUTION: The heat pump type hot water supply system includes a hot water storage tank 1 for storing water inside, a heat pump unit 2 for heating water in the hot water storage tank 1, a solar heat collecting unit 3 for heating water in the hot water storage tank 1, a hot water supply flow path 12 for supplying hot water from the inside of the hot water storage tank 1, and a water supply flow path 14b in which water flows and which is merged with the hot water supply flow path 12. The solar heat collecting unit 3 has a heat collector 31 for collecting solar heat, a first heating flow path 32 for heating water in the hot water storage tank 1 by a heating medium heated in the heat collector 31, and a second heating flow path 33 for heating water flowing in the water supply flow path 14b by the heating medium heated in the heat collector 31.
