PROBLEM TO BE SOLVED: To provide a storage type water heater capable of preventing the degradation of heat insulating performance by securing the mechanical strength of a molded heat insulator while suppressing manufacturing costs, when a vacuum heat insulator is buried into the molded heat insulator for thermally insulating a hot water storage tank.SOLUTION: A storage type water heater includes a substantially-cylindrical hot water storage tank 10 for storing hot water, a body front molded heat insulator 20c and a body back molded heat insulator 20d molded into the shape for covering a prescribed range of an outer side of the hot water storage tank 10, and a plurality of vacuum heat insulators 21a, 21b buried into the body front molded heat insulator 20c and the body back molded heat insulator 20d. The plurality of vacuum heat insulators 21a, 21b include those having different shapes, the body front molded heat insulator 20c and the body back molded heat insulator 20d are sectioned into a plurality of regions, the vacuum heat insulators 21a, 21b are buried in each region, and the vacuum heat insulators 21a, 21b of the regions adjacent to each other are not kept in contact with each other. |
