Re: Shop Heater ?
The secret is to only turn it (them) on when you are actually working, and adjust them to keep them focused on the area you are working. Because the heat is instant, there is no "warm up" time required....so leaving them on is counterproductive. remember, you arenet heating the "space", you are heating you/your tools.....case in point: I changed out a wheel bearing on my truck outside last december at -10, and took one of mine down off the wall and set it up so it was facing me outside. As long as I was in the field of IR it worked great, but yes...if you step outside of that zone the heat is pretty much zero.

Is it a perfect heat set up? Nope...but when dealing with an un-heatable space, it's the only way that works.
A side note: You mention propane...I can not stress enough how bad of an idea a conventional propane heater is in a workshop. A byproduct of propane combustion is water vapour...lots of it. (about 1.5 lbs of water for every lb of propane burned). Pumping that much heat and moisture into a room full of cold iron is a surefire way to turn all that shiny cast rust brown in short order.
I dream of a better world, one where chickens can cross roads without having their motives questioned.
