Just got back from my neighbors machine shop. I have never seen a stove like his Hutch Rebel. That thing can throw heat like nothing I've seen before. Its 33 degrees here today with some wind, basically just a raw damp day. His shop is 26x60. Half way across it was 80 degrees. 3 foot from the stove it was searing heat. Even the old Nashua wouldn't have been close to what this thing was doing. Its basically nothing but a big (36x36x24) box made of 1/4 boiler plate with no baffle. 2 cast doors on the front. There is an uninsulated 9' garage door in the room too and single pane windows. Half the time when I'm over there the service door is open and he is in there working with a tee shirt on. Don't know anything about wood consumption and I'm sure he could care less, there just ain't know other (especially EPA) stove that could do what that baby is doing. He used to heat it with a gas overhead furnace. It was always chilly and the machines were cold to touch. Now they are warm, so warm I think the machines help hold the heat in the place. Sometimes it just takes brute force to get a job done.
