If you still don't want to add power after seeing the other posts, here
are my thoughts:
Put 25 watt light bulbs inside the machines to keep them from rusting.
They stay on ALL the time. (Remove them before using them). Use
whatever you want to heat some of the air. Buy some electrically heated
floor mats to stand on. I stand on one that is about 1 1/2 X 2 feet in
size and it only takes 150 watts. Take all of the cars out of the
garage when using it so your heater doesn't have to heat up tons of metal.
Once upon a time, I had a similar problem and so I made a plastic
"tent" to work in. It had a plastic tarp "roof" about 7 feet off the
floor and it simply draped down to the floor on the side to enclose the
area that I wanted warmed. This was easy to heat. Only problem was
that I had to run support wires across the TOP of the "roof" because it
wanted to pull upwards like a hot air ballon.
If you go this route, you must certainly NOT use an unvented fossil
fuel heater.

My 'shop' is also my garage wherein cars needs to live at night.
The garage is unheated which is kind of a problem here in metro
Chicago ... it essentially means no wood butchery in the cold
months. Moreover, there is not much available in electricity.
There is one circuit that serves the garage door opener +
router + TS + vacuum cleaner ... and that's it. For a variety
of reasons, adding another circuit out in the garage is
impractical/expensive.


So ... what - if anything - can I use to heat a garage safely
that is: a) Not electrically powered, b) Won't kill me of CO
poisoning, and c) Won't ignite sawdust as it flies around in the air?

TIA,
