Infared garage heaters

[CamaroAJ]

i have 2 of these heaters. they do 500 sq. ft. each. its 20* outside today and it took about an hour to get to 60* in my uninsulated 990 sq. ft. garage. once its warmed up only one heater stays on to maintain temp. don't need electricity for them either.

only bad thing about turning them on and off all the time is when they start heating the garage a lot of the cold metal gets condensation on it. it goes away once the garage is warmed up and i haven't seen any rust on the bare metal or my tools so i'm not worried about it.
