Traditional Count Rumford Fireplace Design & Technical Information
Many years ago when I began doing research for my fireplace I had never heard of Count Rumford, now his name is becoming synonymous with good functioning traditional fireplace design. Upon learning of his principles and talking to numerous construction trades people I decided to use this information in constructing my fireplace and I have absolutely no regrets.
The book, Observations On The Forgotten Art of Building A Good Fireplace by VREST ORTON, Esq. (now reprinted and I recommend getting a copy) is a very good reference and gives a lot of background as to how and why count Rumford set about developing his design principles. But to a layperson the formulas become difficult to discern in too much information and some really important details are not emphasized. I know a structural engineer that missed one such detail and his fireplace does not function, (meaning more smoke in your room than up the chimney). This is why I decided to compile what I have learned through research and observations and present it in a clear, concise and condensed way, using many drawings, so a person can build a good functioning fireplace with confidence that their $7000 to $10000 investment is not a waste. I also include helpful construction ideas and recommendations along with a simple damper design.
