Ive been thinking about it and pondering,,,, this thing has two wood boxes that go over the elements, they are about a foot long, 8 inches wide, and 3 inches deep, there on each side. I am going to throw some lump in there in a little while and see what kind of temps I can get it up to like that. There might not be enough air flow from the two stacks on top, but if it even gets close I am gonna install vents in the sides at the bottom for draft.
what do you think?
As for as bieng insulated , the walls on it are 1 1/2 inches thick, and there is a good seal on the door, and it is about an inch thick.
