Those BTU ratings are almost useless...I think they pull them out of their ears. Its the same with woodstoves too. Firebox size means as much as anything...but it gets more complicated with furnaces because some models have better heat exchangers than others. That's the only difference between a Big Jack and a Super Jack...the SJ has a secondary heat exchanger, the BJ doesn't.Something else you can help me understand... why with the others Ashley, Clayton, Hotblast, Englander all have very high BTU output but the Big Jack is far less for more money?
It can take a lot of research to land on the right wood furnace for your home...but I think you are headed in the right direction.
Too big is better than too small. "Too big" you can build smaller fires, or less of them, but with "too small" there is not much can be done other than run the oil/gas/electric heat (or freeze)
