A stove with a 14 inch fire pot is a medium sized stove. They made these with fire pots up to 26 inches, to heat very large homes, stores etc. You will get plenty of heat out of this stove with very economical coal consumption. The minute you strike a match to start the first fire in this stove, you are going to start saving money in substantially reduced coal use.
Needless to say, I am very pleased to see all of these stove restoration projects going on. I would have never imagined it. Just think, a few years ago nobody on this Forum even knew what a base burner was.
