Not good for garage

Was looking for something to help heat my garage here in Texas. It's a two car garage and although it gets in the mid 30's and 40's there are few hard freezes. I first rand it for about 5 hrs. Temp on unit said 61 at start and I had it set for 75 just to see how it worked. After 5 hrs. the temp read 64 or an increase of 3 degrees. So, it didn't help me at all. And yes, the garage door was closed. Maybe it works better indoors in a small room, but pass if you're looking to heat a garage.
