Thanks for the pointers. Mine hangs from the ceiling, just about high enough to walk under. I need to watch my head a little, but it's ok. I had tried it last winter before really insulating, and the tanks didn't seem to burn long. I was aiming for 55 to 60. I agree that that is plenty to work in. Anything more seems wasted, unless you are doing something that requires higher temps.

I'm going to fill the tanks Friday and will report back in the coming weeks.
