Greetings,
I live in central Michigan and have rocket mass heater. My insurance company is requiring me to have it inspected and certified by the County. The County won't approve it unless I have a seal from a mechanical engineer....I am now looking for someone who will give me the seal without breaking the bank. I have scale drawings and pictures of the construction process if that helps.
Thanks...b
Each area is different when it comes to insurance and RMH's. I found this thread on codes and thought there might be something in it that could help until someone more knowledgeable in that area can help you out further. Good luck!
