Abstract
A portable radiant heater comprises an electrically energized heating element extending along a vertical axis. A first, multi-faceted, concave reflective surface is positioned to the rear of the heating element. A second reflector is positioned forward of and in close proximity to the heating element. The first reflector directs radiant energy received directly from the heating element and indirectly from the second reflector forward with minimal radial dispersion.
