Abstract: Disclosed is a thermoelectric fan for use with radiant heaters, particularly catalytic heaters. The thermoelectric fan of the present invention comprises a housing sub-assembly coupled to a thermal plate sub-assembly, the housing sub-assembly comprising a shrouded circulating air moving member, such as a fan blade, powered solely by the conversion of heat from a separate heater into electricity via an integrated thermoelectric module. Also disclosed is a self-powered fan that can safely perform in hazardous atmospheres while converting radiant heat to circulate air. The thermoelectric fan of the present invention ensures that the air within the space to be heated is more effectively distributed and temperature gradients are minimized. Also disclosed are methods for assembling, installing and safe operation of the thermoelectric fan.
