Not a good thing for a dusty shop though as the fan REALYY moves air !!!
Those Hot Dawg's are nice, very compact and can be mounted what 1" from the ceiling?
But I do some painting in my shop that's why I like radiant gas heat. It's silent and sturs no dust up when I fire it up to help dry my paint. And when I open the garage door to move trucks around the heat stays in the shop.
