I live in Wisconsin and due to the continued rise in heating costs, my brother-in-law is looking into installing an outdoor wood burning furnace to run the radiant heat in his home. His home is 4300 square feet with a main floor and finished basement. He wants them both on separate zones. Does anyone have any information that would help him locate the best brand, size, etc? Does anyone have one of these ?

My dad`s friend, in Upstate NY, has one and loved it so much he became a dealer. The advantages are clear: ability to burn green wood, large capacity, and they only need to be filled once a day. However, my dad`s friends house is half your size and he lives in the mountains. A house your size may require two, and if you live in a nice area, they may not be allowed.
