PROBLEM TO BE SOLVED: To suppress degradation in hot water storage efficiency to follow heat radiation from a gap for leading a lead wire of a thermistor detecting a hot water storage temperature.SOLUTION: A hot water storage water heater comprises: a hot water storage tank 1 storing hot water supply hot water supplied from a lower portion and discharging the hot water from an upper portion; a plurality of thermistors 14a to 14g attached to a side surface of the hot water storage tank 1 and detecting a hot water storage temperature; lead wires 15 leading from the respective thermistors 14a to 14g; and a molded heat insulation material 13 covering almost an entire surface of the hot water storage tank 1. A lead wire leading hole 136 is formed in a portion of the molded heat insulation material 13 near an intermediate height of the hot water storage tank 1 so as to lead the lead wires 15 of the plurality of thermistors 14a to 14g to outside of the molded heat insulation material 15 from the lead wire leading hole 136. |
