This is an exciting time for Maine in alternative energy. My good friend in the plumbing and heating business sells fuel oil, installs furnaces, etc. A couple years ago, I asked him why he wasn't getting involved in pellet boilers. All kinds of reasons then...
He's full into to installing pellet boilers today, building hoppers, etc. I'm 4 years now heating with pellets. In those 4 years I've seen pellets go from scarce to everywhere, the quality go up, and the price go down. The systems to heat with wood pellets(not a perfect fuel), are now in place.
