Question: I read in one of your digest questions about creating ductwork to transfer warm air generated from a wood stove to other rooms of the house. Is there any way to use existing air conditioning ductwork to transfer air from the stove to other rooms of the house? The ductwork runs through the room where the stove will be located. If this is possible- how strong would a fan or blower have to be to push the air through the ducts? Answer: It works best if a return (the suction from a heater) is located in or near the room where the stove is (or nearby). In this case- just turning on the "fan only" control on the heater would circulate the air. One concern is that some returns can cause a negative pressure in the room and cause the stove to backdraft or backpuff, so make certain you keep this in mind.
