ABSTRACT:
A portable heater providing both radiant and forced air heat includes a plurality of vertically oriented, horizontally spaced apart quartz heating tubes is partially surrounded by a common reflector configured to open at an obtuse angle at each quartz tube. The reflector is perforated to allow air to pass out from the interior of the heater. A housing surrounds the reflector and heating elements. A fan located toward the top of the heater draws air inward and down the channels behind the reflector from which it emerges past the heating elements. Control knobs for controlling a thermostat and output power level are located at the top surface of the housing. The heater also has automatic safety controls for shutting off power in the event the heater tips over or overheats, and an overcurrent device.
