Claim Text:
1. An electric resistance heater assembly comprising: a) a first insulator having a plurality of spaced apart openings therein and having an annular shape; b) at least one heater element woven through the plurality of openings so that first portions of the heater element extends upwardly from a top surface of the first insulator and second portions of the heater element run along a bottom surface of the first insulator; c) a second insulator being generally annular in shape, a top surface thereof positioned adjacent to the bottom surface of the first insulator to electrically isolate the second portions of the heater element; d) a plate positioned adjacent a bottom surface of the second insulator, the plate having an annular shape with inner and outer peripheral edges, the plate further including a plurality of tabs, each of the tabs located on either an inner or an outer peripheral edge of the plate and extending therefrom, the tabs sized to be bent over the first and second insulators to clamp the first and second insulators together to form an annular electric resistance heater assembly comprising the first and second insulators and the plate; and e) means for mounting the annular electrical resistance heater assembly to a structure to support the heater assembly in place.
