We have a 80k btu boiler that can't keep up when it's below 0.
I do what I can to winterized, film on the windows. All outlets and switches in exterior walls are sealed.
It depends when I'm around. Some times I'm here for days. Some times I'm not home for days. But the wife is usually here when I'm not.
I like the looks of the 50-93, but I think the 83 fits with the hardwood floors and cedar ceilings. The wife would have final say, just like to have the info she ask about. I know she will ask "what will work best.
I already have a 8" stove pipe downstairs, so either one will hook up with out issue.
She is a capable gal, and tends the wood stove just fine when I'm not here. I think she will learn coal without issue.
