We use a 20 in box fan to circulate the air behind the stove and move the warm air throughout the house, sometimes if the eyes are heavy and a feeding is missed i come down and the fan is blowing cold air around. i solved that. i bought a snap themostat on ebay (turns fan on @100 and off when comes back to 100) wired it in a surface mounted receptacle box and mounted the receptacle near the ceiling 4 feet away from the stove now when the room is quiet i know i have to go and feed the stove and the little residule heat isn t lost to the fan.
