This heater cranks out the BTUs. Have not had a chance to test it on a sub freezing day, but used it when in low 40s outside. After running for about 15 minutes in my one car garage, I had to shut it down, because it was turning my garage into an oven. This is clearly overkill for a space as small as a one car garage, but my garage space is un insulated and I am hoping to be able to keep working in there when the temps sink to the 20s.
I would definitely purchase this again.
