I recently installed a Mr. Heater Big Maxx 45K BTU NG garage heater unit in a 22x26' garage, 9' ceiling with a loft above. I had looked at the manufacturer you posted about also, but I was able to find more dealers and better pricing online for the Mr. Heater unit. The specifications and style of the units are almost the same. So far I am satisified with the performance. It was a very simple and economical install. This type of heater seems to be ideal for garage/workshop.
