Claims

[Scope of utility model registration request]

A first tank that heats the liquid with a first heating heater whose electricity is controlled by the opening/closing operation of a first thermoswitch, and then keeps the liquid warm with a first heat-retaining heater. A two-tank type having a second tank in which the liquid is heated by a second heating heater whose energization is controlled by the opening/closing operation of a second thermoswitch, and a second tank which holds the liquid while keeping it warm by a second heat-retaining heater. In the electric water heater, a first relay that operates when the first thermoswitch is opened and a second relay that operates when the second thermoswitch is closed are provided, and the second relay is operated when the second thermoswitch is closed. and a two-tank electrical system, characterized in that a parallel circuit of a normally closed contact of the first relay and a normally closed contact of the second relay is inserted in series in the energization path to the second heat-retaining heater. water heater.
