Abstract
The electric heater herein disclosed is particularly adapted to heat a fluid and to provide a broad, substantially flat heater surface exposed to the fluid to be heated. The heating element is well adapted for deep fat frying use in that it is of high voltage and is economical to manufacture. The invention makes use of standard elongated, tubular, metal-sheathed heaters which are produced in large quantities for a multitude of uses. Such elements are slid into a metal tube of selected diameter and wall thickness, and the assembly is flat-pressed in appropriate sections with the ends round for termination with such fittings as are required. The assembly may then be bent to produce a desired configuration.
