I run a quadra fire woodstove in the house and an old vestal stove in the shop. Paid 200 bucks for the quadra fire, got the vestal for free when I installed a new stove for a customer and they told me if I could haul off the old one, I could have it. Heated with it for years until I built us a house too efficient for it. Even in the last house we had the windows open a lot of the time. Then we got the little quadra fire. Last year, we never ran it. Heated and cooked for a year on 200 gallons of propane with an 1800sf house with high ceilings thoughout. Used a radiant ventless wall heater on the lowest setting all winter. Turn it up any, house gets too hot. May have gone a little overboard with the air sealing and insulation...
