HOT WATER SUPPLIER

PROBLEM TO BE SOLVED: To provide a solution for a problem in which thermal retention performance of hot water of a hot water storage can body is an important subject because the capacity of the hot water storage can body decreased as a whole size of a hot water supplier becomes smaller and influence of temperature fall due to heat radiation of stored hot water is severe. SOLUTION: A foaming thermal insulation material 300 is formed by combining a foaming thermal insulation material (a front side) 310, a foaming thermal insulation material (a rear side) 320 and a ceiling side is covered by a foaming thermal insulation material (a top side) 330. As a space forming part 331 formed by a recessed part and a pipe temperature retention part 332 formed along a shape of a hot water output pipe 202 and the like provided at an upper part of the hot water storage can body are provided at a back face side of the foaming thermal insulation material (a top side) 330, heat radiation especially from the upper part of the hot water storage can body is suppressed with a thermal insulation effect not only by the foaming thermal insulation materials but also by a space layer.
