I have to agree on a cold shop, I have a 40 x 40 clear span shop, 14ft walls (I needed to be able to drive my tractor in). I am not in agreement with anything that has flames (I.E. kerosene or propane " flame throwers", I have one but don't use it. I have an issue of an explosion or fire when I do any spray painting, wood staining / sealing / etc. , even a wood burning stove bothers me. Currently, I have no heat or air in the shop, it is well insulated r19 walls, r30 ceiling and insulated sectional doors (one at each end of the shop) but it still gets cold in there. I have tossed around the idea of ceiling radiant heat ( I have the power for them) but not sure I have the clearance between the ceiling and the sectional doors.
I have to say, this was an interesting topic.
