Ceiling mount heater

Yeah.... that's like three small hand held hair dryers, three. You are gonna need a little more than that!
Yes, Lefty71, no doubt you are right, but despite its failure to heat it increased my electric utility bill a lot!

It must cost an absolute arm and a leg to heat a shop with one of those great big electric ceiling heaters that you see occasionally.

We don't have any natural gas in the area where I live, so the only alternative is propane, which is in high demand and is therefore somewhat expensive.
