Abstract
A foldable electric resistance heater comprises at least a pair of insulator plates with a resistance wire threaded through openings in the insulator plates. In one mode, the insulator plates are folded with respect to each other and fastened together using one or more fasteners. In another mode, the plates can have other angled configurations with respect to each other. One or more insulators is positioned between the folded plates or adjacent the plates to isolate the resistance wire. The folded plate configuration and resistance wire provide significant advantages in manufacturing costs while forming a more robust heater configuration.
