I am putting up a 30X48 building with 10' side walls in a couple of months and am looking to install a Hitzer 55 Coal/Wood stove in it. I have an OWB now but with the location of it and the new building it won't be an option to use. I have 3 questions I hope I can get some help on. #1 This building is going to be insulated to the hilt and will have 1 20' garage door and 1 9' door and 3 windows. Will I need an outside air supply for this or is it a big enough building to get by without one? #2 Any comments on the Hitzer 55 stove good or bad? #3 Will be burning well seasoned Oak and Ash in it can I expect an 8 hour burn time out of this stove? All comments would be much appreciated.
