Hi, I have an old Cemi free standing, rear 6" flue, woodstove, probably built in the early 80's. It is well built out of 1/4" plate, and I have used it daily thru the winters for about sixteen years to heat my workshop. Paid $65 for it, rebricked it a couple times, and replaced the angle inside holding the brick three or four times. It puts out quite a bit of heat, but also eats a lot of wood to do it. I can find no info on this stove, only on a fireplace insert they sold about the same time. I think it was rated about 105K input BTU at the time it was built, but the output was nowhere near that. I want to get a new non-cat stove to cut down on my wood consumption as I get older. I was wondering if anyone knew about how much BTU it 'actually' puts out compared to today's stoves? 30K BTU or so..???
