Used to burn 5-6 cords of wood/year to heat our Cape Cod style home. It was becoming a chore to handle all that wood plus the dirt and smoke associated with it was starting to affect my wife who has some respiratory issues. 11 years ago we ditched the wood furnace and the oil furnace and put in a ducted heat pump. That has been great especially in the summer for the AC. Four years ago we bought a Harmon pellet stove. It has been GREAT. We basically heat the house entirely with wood pellets.
