To provide a storage water heater improved in the efficiency of an apparatus by reducing a radiation loss from a hot water storage tank and improved in usability by preventing the run-out of hot water.
This storage water heater includes: a heating means 1 heating water; a hot water storage tank 2 storing hot water heated by the heating means 1; a mixing valve 3 mixing the hot water in the hot water storage tank with feed water; a hot water supply pipe 6 supplying the hot water mixed by the mixing valve 3 to a hot water supply terminal 16; covering bodies (10a, 10b and 10c) surrounding the hot water storage tank 2, a mixing valve 3, and a hot water supply pipe 6; and covering thermal insulators (11a, 11b). The covering thermal insulators (11a, 11b) are provided on top surfaces 10a of the covering bodies (10a, 10b and 10c) and at least the upper part of the side surface 10b thereof. Since a heat capacity of the hot water storage tank 2 is maintained, usability is improved by preventing the run-out of the hot water, and electric energy required for heating the water is reduced to improve the efficiency of the apparatus.
