Hi All! I'm new to this forum...and have been reading many different threads with many different options. I'm new to the world of RMH, Dragon Heaters, etc. I would like to ask for some help-I have attached a picture of an existing chimney stack that is in our house. We have an adapter for a 6 inch pipe. The stack itself measures about 22" wide. I think after reading through different threads, I've come to the conclusion that a dragon heater/castle build may be the most efficient use of space for us? The whole house is about 1000sq ft, and this stack is smack dab in the middle! (quite convenient really) We'd like the smallest footprint possible, but I'd have no idea where to start in short of buying books, etc. I will gladly do that, but would appreciate your input first so I'm not buying extraenous sources of information. The floor is laminate over concrete (no vapor barrier-it was done a LONG time ago, and we only rent, but the owner has given us permission to do as we wish) We are in SW Wisconsin. I have checked about permits, and since our house was built before June 1, 1980, we do not need a permit at all!
