摘要： PROBLEM TO BE SOLVED: To obtain a heat pump hot water supply apparatus in which hot water in a bathtub can be reheated up to a desired temperature in a short time. SOLUTION: The heat pump hot water supply apparatus 10 comprises a heat pump unit 11 comprising a compressor 16 and a heat pump heat exchanger 18, a hot water supply unit 12 where a heat exchanger 27 can heat up water by the heat of refrigerant and store hot water in a hot water supply tank 26 which can supply hot water to a faucet 13 and a bathtub 14 and a heat exchanger 28 for bathtub can heat up hot water in the bathtub and heat insulate the hot water, and a controller 15 for the heat pump unit and hot water supply unit. At the time of reheat operation of hot water in the bathtub through operation of a switch 71, the controller executes a control for raising the temperature of hot water in the bathtub by a specified level above current temperature of hot water in the bathtub at the time of starting reheat operation.

摘要： PROBLEM TO BE SOLVED: To provide a tank unit which can secure the mounting space of a reheating heat exchanger and pumps to constitute vibration members, which are housed in a unit body together with a hot water storage tank, and whose hot water temperature stratification in the hot water storage tank is hardly affected even when they are mounted on the tank. SOLUTION: In this tank unit 12, the hot water storage tank 22 for storing hot water heated by a heat pump cycle therein, and a heat-insulation material 52 which covers the hot water storage tank 22 for keeping the hot water in the tank hot are housed in a unit body 12A. The heat-insulation material 52 is formed by a foamed heat insulation material in which a holder 52A for holding pumps 27, 32 thereon is embedded through a foam process, wherein the pumps 27, 32 are installed in pipings 26, 28 connected to the hot water storage tank 22. The foamed heat-insulation material 52 is nearly equal in height to the hot water storage tank 22, and covers a side portion of the tank 22, and the holder 52A is located at the lower portion of the heat-insulation material 52.

摘要： PROBLEM TO BE SOLVED: To provide a tank unit securing attachment space for attaching a reheating heat exchanger and a pump becoming a vibration member to be housed in a unit body along with a tank, and hardly breaking a hierarchy of temperatures of hot water in a hot water storage tank even if they are attached to a hot water storage tank. SOLUTION: In the tank unit 12 including pumps 32, 27 sending hot water heated by a heat pump cycle, and the hot water storage tank 22 storing hot water heated by operation of the pumps 32, 27 in the unit body 12A, the hot water storage tank 22 is covered with a heat insulating material 52A heat-insulating the hot water on at least its side part, and the pumps 32, 27 are attached to the side part of the hot water storage tank covered with the heat insulating material 52A by using a support tool 53.
