PROBLEM TO BE SOLVED: To provide a heat insulation structure which reduces the number of components made of a heat insulation material thereby reducing assembly labor and costs.SOLUTION: Cutout parts (31, 32) of a heat insulation body part (10) do not penetrate through the heat insulation body part (10) in a radial direction. Thus, heat of a hot water storage tank (121) does not leak to the exterior. Therefore, a heat insulation material formed as separate components for closing the cutout parts (31, 32) is not needed and the number of components made of the heat insulation material is reduced. |
