I have this same two disc catalytic heater as below. It is quiet (unlike the torpedo heaters and the trash can heaters) and the IR heating is great for heating up metal surfaces and concrete floors. Tools can be handled without gloves and the cement floor isn't so cold. I use it in combination with a fan mounted high up to blow hot air down from the ceiling. Works great for a $80 heater.
I also have one of the trash can 80,000 Btu heaters, and I rarely use it. It's a convection heater and like the other poster indicated it creates a moisture issue.
I think next year, I'll install on of those natural gas heaters like the Hot Dawg.

The tank cooks steaks in the summer and heats my garage in the winter!
I have a 3 car garage w/insulated walls and insulated roll up doors, after 15 min warm
up, I am working with sandals and swim trunks in the dead of winter!
