I've been seeing these things pop up here and there. Its only a matter of time that they will be regulated next. Anyhow I watched this video and was curious about wood consumption. According to the owner, its only 2 years old and looks horrible. On top of that the ductwork entering the home isn't insulated. Claims only to have used 2 cords, and replaced 2,500 in LP, Yeah right. First video I have seen of these units and not impressed the least bit.
