Hello everyone. I've been poking around here for a while and just joined hoping I can get a little help with a wood stove for my camp. I'm trying to heat approx 250 sqft of uninsulated camp in upstate NY a few times during the winter and in early spring and fall. I'm limited on room and I came across an Ashley automatic 25hfr that would be perfect. My question is about the inside liner. Its a little warped but the outside shell is fine. Can the inside liner be replaced or used as is? The few times I do burn it would be basically continuous for 2 days or so and I was a little worried about how thin the walls are. Any help would be appreciated. Thank you
