I installed my own wood stove for 1200 bucks. Bought a used stove and all new Selkirk chimney products from Home Depot. Cost is 300 bucks a year for wood. I could do it for free by cutting up pallets. I use the forced air gas "fan only" setting to circulate air. Ceiling fans too. With passive solar I could probably lower the cost to $150. Craigs free wood sometimes.
