Jotul F 50 TL

wow in GA? i would say yes. thats a pretty big heater. i would think a 2cu/ft would do fine. book says its for homes up to 2500 sq feet.

what made you choose that one?

guess thats a older model. the tl 50 rangley says its good to 2500sq on the web.

either way, i would think a 2ft stove would be a pretty good choice.

Are you more north/west or south/east in Ga?

How's your home's inslation and weatherization?

So. . .south of ATL? Yeah, ~2 cu ft is probably the appropriate size.
However, that was the appropriate size for our house, and I had to tighten up the house quite a bit for a modern 2-cu-ft stove to be able to heat this place the way the 5-cu-ft pre-EPA monster did. This is the preferred approach though. Less wood used due to a more efficient stove and a tigher house. Less frequent reloads.

According to Buck, the model 74 you are used to is 2.6 cu ft. . .if you want similar performance, look for a firebox of similar size. Basically, a 2-cu-ft stove is only going to give you 80% of the BTU's that a 2.5 will, because you can only stuff 80% as much wood into it. Mfr specs for sq footage heated do not mean much. There is no standard for the spec, and they do not know your house nor your climate. Focus on firebox size, preferably measured yourself. Lastly, a catalytic stove like the Buck 80 would give you more flexibility. (Cats can burn cleanly at lower output levels than non-cats can. . .EPA doesn't allow air intake to be shut on non-cat designs.)
