ABSTRACT:
A radiant heater assembly is provided that includes heating element for generating heat radiantly to warm a space to be heated. The heater assembly includes a sensor for sensing temperature within the radiant heater assembly. An overheat control unit is provided for automatically disabling the heater elements upon exposure of the sensor to temperature in excess of a predetermined threshold temperature. Alert indicators are provided for indicating disablement of the heater elements upon actuation of the overheat control unit. A tip-over switch is provided for activating the alert indicators independent of actuation of the overheat control unit in response to predetermined tilting movement of the radiant heater assembly relative to a normal upright position.
