ABSTRACT:
A combined heating element and thermostat for use in a water heater. An electrical heating element includes a U-shaped rod having first and second legs, the first leg being longer than the second. A plug fits in a sidewall of the heater. The rod is installed in the plug. The outer end of the legs are inserted in the plug. A thermostat is also mounted in the plug. An electrical terminal is attached to the plug and includes a first terminal contacting the outer end of the first leg of the rod. A second terminal contacts the other leg of the rod. A switch connects and disconnects the second terminal with the second leg of the rod. The switch is movable by the thermostat and includes a bumper element. The thermostat moves the bumper to disconnect the rod leg from the terminal when the water is heated to a desired temperature.
