I am getting ready to build a ranch house. I have been trying to figure out my heat source. My dad and I have a 30 ton wood splitter. Lots of wood. Dump trailer, backhoe, bobcat etc. He also burns lump coal. I am getting sick of the wood deal and was thinking about wood pellet stoves. Everyone has been telling me to run from geo thermal. They said its def not what its cracked up to be when it really gets cold out. I was thinking about doing something like this. http://www.harmanstoves.com/Products/PB105-Pellet-Boiler.aspx Anyone have any experience with wood pellet stoves? or any advise?
