A fan, such as a ceiling fan, for heating and circulating air in an enviroment includes a plurality of fan blades rotatable by an electric motor. The blades are each provided with an open interior space defining an air flow passage transversely through the thickness of the blade in which is mounted an electric resistance heating element. Louvers having a plurality vanes are provided on the opposite sides of each fan blade over the open interior space thereof for deflecting air, upon rotation of the fan blade, through the open interior space over the heating element therein and to direct the heated air to the enviroment. The vanes of the louvers on the opposite sides of the blade are oppositely angled. Operation of the heating fan may be controlled by a thermostat responsive to the temperature of the enviroment.
