i currently have a PE Spectrum classic with all the nickel trim, legs, and door; i think it's one of the best looking stoves I have seen. We really like it and it does a good job heating out split level 2000 sq. ft. home nicely from a central location in the lower level near the stairs. Recently I found a pretty good deal on a BK king classic with gold door and blower kit. I was told it was 7 years old and only burned for 2 seasons (picture attached). I am wondering if it is worth the hassle to change it out from our current setup? Will I notice a big difference in heat output? I know burn time will be way better but I am more curious about constant heat output. Also, can a BK use an adapter down to a 6 inch pipe? I have attached pictures of my current stove and the BK that is for sale. Thanks for the opinions.
