Have had 2 BK Princess Cat stoves, our "new" one is now 14 years old and I finally replaced the cat last year.
With your sq footage sounds like the King model would be a great fit.
We burn a lot of Pine because it is free, but even then and without Really loading the stove up it is still putting heat out in the mornings. Gone over a month many times with the fire never being out and never getting up at night to re fill it. Although not recommended we have started burning one or two energy logs mixed in, and they do work, but a person would never want to ever 'load up" a firebox on a catalyst BK stove with just them and BK does not approve.
BK stoves do cost more than most brands, and they aren't as nice looking as some others, but if long burn times while the stove is turned down a bit is your goal
Blaze King Cat stoves are hard to beat.
