we live in North Iowa next to Minnesota we hit O degrees and below, with the prairie winds. we have a large furnace in the basement and an inside chimney. this is our only heat source, so letting the fire go out in out of the question this house is at 100 yrs old. We are blessed to have a good supply of burr oak to fire with. I do not like using any thing else ! We can get 34" long pieces into the fire box. which is nice for night long burns, a freezing house is no fun. Chimney fires are so common with outside chimneys, we have been burning wood for 44 yr.
