We have had our 7100fp for 3 years this winter. I am really disappointed about the heat output. I have read everything that I can find on the 7100fp. We replaced our old timer woodstove with the 7100fp. The old timer would get our home up to 90 degrees on a 10 below 0 day if I wanted to. The 7100fp we have trouble getting up to 70 degrees if I run it wide open. I am burning well seasoned hickory. I do not know if I am not doing something right on the settings or if this is the best the 7100fp will do. Any help would be appreciated.
