We've got a bit more than that, 25X40ish, with 30 ft at the roof peak.
It's completely uninsulated (well, the overhead doors are insulated)
and unfinished (exterior walls are 3/8" (maybe 1/2) ply wood; there
are no interior walls.). A 30K BTU Mr Heater propane heater will,
given time, warm the place up. I did the timing belt on a car last
winter when it was just above zero. It wasn't pleasant, but I could
keep the whole space at 40F, with the area in front of the heater
quite a bit warmer. (Tip: keep your tools in that space...) 50K
would be nicer.
I run it off a 40 lb tank. a 20 lb tank won't keep up, and once it
hits half-empty it gets worse. You can get manifolds that let you
attach more than one tank to hte same appliance, which helps some.
