Abstract:
1. A heating system comprising: a cabinet having at least two opposed inner walls defining an interior heating chamber and a door to allow access to the interior, the facing inner surfaces of the opposed inner walls being substantially uninsulated to provide heat transfer through the walls to air contained therebetween within the interior heating chamber; a heating pad subassembly disposed on an exterior surface of the walls of the cabinet, the heating pad subassembly including a heating element and a plurality of openings formed through the heating pad subassembly; an insulation disposed on an exterior surface of the heating pad subassembly; a plurality of common couplings attached to the exterior surface of the walls, and wherein at least a portion of the plurality of couplings extend through the plurality of openings and wholly through the insulation so that the heating pad and insulation are receivable on the couplings by sliding therealong toward the exterior surface of the wall a plurality of retainers coupled to the outwardly extended end of the common couplings and positioned to compress the insulation along the common couplings against an outer surface of the heating pad subassembly; and at least two outer walls substantially parallel to and displaced out from a corresponding inner wall to contain the heating pad and insulation between an outer wall and corresponding inner wall.
