ABSTRACT:
A heating unit includes a frame and a substantially flat radiant heating surface supported by the frame. A generally parabolic trough with a reflective inner surface is mounted along one edge of the periphery of the heating surface, and contains an elongate heating element. Further, a reflective flap is hingedly mounted adjacent the trough but remote from the heating surface, disposed so that at least a portion of the radiant energy reflected out of the trough by the reflective inner surface is re-reflected by the flap, depending upon its angulation with respect to the heating surface.
