PROBLEM TO BE SOLVED: To provide a hot water storage tank unit having high heat insulation performance.SOLUTION: A hot water storage tank unit includes: a hot water storage tank 2; an outer box 3A housing the hot water storage tank 2; a water supply pipe 11 and a water inlet pipe 12 connected to the hot water storage tank 2; and a plurality of inner legs 4A, 4B, 4C supporting the hot water storage tank 2 in the outer box 3A. In the outer box 3A, formed are injection ports 8, 8 injecting a foamed heat insulation material 6 between the outer box 3A and the hot water storage tank 2. When the inside of the outer box 3A is viewed from the injection ports 8, 8, the injection ports 8, 8 are arranged at positions of being able to overlooking the depth of the outer box 3A from the injection ports 8, 8 without being disturbed by the hot water storage tank 2, the water supply pipe 11, the water inlet pipe 12 and the inner legs 4A, 4B, 4C.SELECTED DRAWING: Figure 3 |
