The T-stat on my stove has never allowed it to burn well much below a 1.75 setting. Right now, it's cold enough outside to see your breath, so yeah, I have a fire in the stove. Currently, T-stat on 2, fans off, Cat @1250, stove top @390, flue @350. Pine slab wood in box. It's 10:00 pm , I'll turn it down to 1.5 for the next hour, see what happens, then report in.
