ABSTRACT:
The novel electric heating element is particularly useful as a water heating element, although its use is not so limited. The element comprises the usual metal-sheathed heater having electrical termination at one end of the sheath. The customary water heating element has a sheath of hair-pin formation, with the ends of the two legs of the sheath connected to structure which serves as a mounting member and an electrical connector. Such structure in the present application is of molded plastic with a metal insert.
