PROBLEM TO BE SOLVED: To provide a hot water supply unit which can be installed without expanding a site area and can suppress pressure resistance performance.SOLUTION: The hot water supply unit includes: a hot water storage tank 1 for storing hot water; a heat pump device 2 in which a water heat exchanger 22 heating the water within the hot water storage tank 1 is installed in a tank lower part; a water supply pipe 14 connected to the hot water storage tank 1 and supplying water inside the hot water storage tank 1; and a hot water supply pipe 15 connected to the hot water storage tank 1 and supplying hot water within the hot water storage tank 1 to the inside of a building. The hot water storage tank 1 is formed into a shape in which the area of an upper/lower face 11a, 11b is set larger than that of a lateral face 11c. The hot water storage tank 1 is installed so that one end side of the upper face 11a is arranged on the upper side relative to the other end side on a roof RF of the building and is inclined so that a space SP for installing an apparatuses including the heat pump device 2 is formed between the hot water storage tank 1 and the roof RF. |
