I have been looking on craigslist for a stove for my new pole barn that is 1560 sq. feet with 12' ceilings for 28' and 15'11" for the remainder of the space. I was told that not only sq. feet matters but that cubic feet plays in on the size stove I will need. The barn is fully insulated and I now heat with a 225000 btu high hat propane construction heater when I'm in the building. I have seen an Englander stove and a Pine Barren Coal Barren wood and coal stove so far. I also went to the DS Machine factory in Pa. and spoke to them about a Heatright 120 wood and coal stove and there model 1600 coal circulator. I was told that any of these units would heat my space with no problems. A friend of mine is attempting to get me to build a two barrel stove out of stainless barrels, I'm not too keen about the barrel stove due to insurance coverage. I am sure that folks here have building this size and I only want to make a purchase once. If you would please give advise on this subject I would be thankful. Info on size and manufacturer and barrel stove use will be very helpful as well. Thanks Mark
