ABSTRACT:
A fireplace insert comprises an inner housing and an outer housing spaced from each other. Thermostatically controlled fans circulate air between the inner and outer housing to cause the air to be efficiently heated before it is distributed into the area or room to be heated. Adjustable vents control the flow of combustion air, and a baffle minimizes the loss of heat through the flue.
