Abstract
A heater assembly includes heating element for generating heat to warm a space to be heated. A heat sensor is provided sensing the temperature within the radiant heater assembly for automatically disabling the heater elements upon exposure of the sensor to temperature in excess of a predetermined threshold temperature. A tip-over switch is provided for disabling the heater elements in resonse to predetermined tilting movement of the radiant heater assembly relative to a normal upright position. Alert indicators are provided for indicating disablement of the heater elements upon actuation of either the heat sensor or tip-over switch.
