Abstract

PURPOSE:To permit the hot-water temperature of an electric water heater to be adjustable and to reduce the radiation loss by connecting a heating element to each of a plurality of thermostats having different setting temperatures, and providing a change-over switch between an AC power source and the thermostats. CONSTITUTION:Heating elements 4 and 4' are connected to a plurality of thermostats 8 and 8' having different setting temperatures, and a change-over switch 7 is provided between the thermostats 8 and 8' and an AC power source 6. Thus, the change-over switch 7 permits the selection of the connections of the AC power source 6 and the thermostats 8 and 8' and the heating elements 4 and 4', so that the boiled-up temperature of the hot water in a hot-water tank 1 can be selected according to purpose. Moreover, making the power capacity of the heating elements 4 and 4' to differ from each other permits the hot-water temperature to be lowered when the water temperature is high, e.g., in summer, so that the radiation loss of the hot water can be reduced.
