Garage Heat

I'm wondering if now maybe I should plumb NG in. But I guess I was wrong in thinking the torpedo heater would be less efficent.

I bit the bullit, and ran NG to my detached garage in Kansas, and I also have it in my attached garage now.
I put those hanging furnaces in both places, that are vented out through the roof.
It is wonderful to be able to work on your toy in short sleeves, when it is 10 degrees outside. :D
