I feel your pain, dude. I too have a wood stove. It is an old fisher Papa Bear. Good stove – excellent quality materials and workmanship. Problem is that it was designed and sized for the house before I did the Bob Vila thing to the house. Before I renovated the stove was OK in the great room. But the house was almost completely uninsulated, so when I renovated, I insulated the house like a thermos bottle. Now the Papa Bear runs me out on all but below-zero days. The stove has so much heat transfer area (stove is about the size of a desk) that if you build a small fire it goes out – snuff by heat removal. If you build a fire that stands up to the heat removal you have a blast furnace and it runs me out of my well-insulated great room. This rascal is quite capable of eating up a cord of firewood in four days if I could get the heat to the rest of the house.
What I’m thinking of doing is welding some PlateCoil

Just a matter of moving the heat where you want it.
