Been reading ya'll for years. I do a lot of playing around with my Grampa Bear Fisher, grew up with one and now we have one in our 1883 old farmhouse. Read home with no insulation... literally.. NONE. Its time for a new stove. Here's what I need with my house. A stove that will maintain 350 in 30 deg weather, 450 in teens, and 500 in neg. All through the night and day. I burn Red Fir & Tamarack, as if its going out of style. 5 cords last year. So the age old question Cat or no Cat. I'd love to know from folks who have one or the other, and tell me about their burn times/ satisfaction with the stove. Kuma is made right up the road from me, so I'm interested in going local. However BK's 30 hr burn time is impressive. Does anyone know at what temp that is? Thanks for your help.
