I installed a 300,000btu suction unit with two burners into our 80x80 shop last year. You don't feel the heat off it either. I set the shop at around 5C and it's nice in there. Biggest problem is management sometimes turns the heat down in the evening and then it takes four hours to warm up again the next day.
