Garage heat

I live just a few miles north of him, and wood is not a problem. My first winter in new house with a similar garage I had stapled 3 mil plastic on walls and ceiling. I used a thermostat controlled torpedo heater and used K-1 kerosene. Supposed to burn cleaner, but a little more expensive than other stuff. So plastic and a unvented propane heater would be best, in my opinion. Blains Farm & Fleet off Durand (11) in Racine has them around $100. Let me get to PC and I'll post a link.

Ok, I was way off on the price, I forgot about using the indoor model, here it is.
