I have a huge Fire King stove in my basement heating a 2200 sq ft ramber with full basement. (2200 on each). Not our primary heating source. Stove heats well but no blower to push hot air and eats wood rapidly. It is 36" wide and has a large fire box. I need to replace the heat rope. When I crank it down it will continue to burn but provide very little heat. (ie: efficiency drops off a cliff during really slow burns) I burn mainly on weekends but would love to burn more often but given low burn times, I often don't hassle during the week. 1) Will a new modern stove make that much of a difference? 2) Blaze Kings (Princess) receive rave reviews but I'm nervous about the Cat combuster. Can you burn the Blaze King's without the Cat installed? What will happen? Not that I plan to but I'm just thinking about emergencies, etc or if I want to burn some crappy wood... 3) What type of burn times are you getting out of your Quadra-Fires (4300, 5700 ), PE's and Lopi Endeavor stoves? 4) I've read about PE stoves having baffle issues. True? Would you go with Quadrafire over PE? 5) Going with a bigger box is nice because I don't have to split smaller pieces, BUT do larger boxes lend themselves to the law of diminishing returns (ie: they start to eat too much wood....less efficient) PS: I usually burn lodgpole pine. Live in northern Utah.
