: Having a carbon monoxide detector would be my first rule for any heat source.

Concur on the CO detector.

I have liked having a wood stove, and do most of my heating with same. Most of the wood I get from my own land, and it gives me something to do with all those off cuts, scraps, shavings and sawdust. Getting the temperature of my shop up to 85 degrees F, is no problem even in sub-zero F, temperatures. I also have a propane heater and a 1500 Watt electric heater but do not use them much. I guess it's the firebug in me.

The one downside is I need a lot of make up air for the dust collection. I have two 4" air pipes that bring make-up air from the attic, as well as a 6"X8" hole in the ceiling that I can slide open. If I turn on the dust collection without all three wide open, I will have a smoke filled work space in less than a minute.

My 27'x23'x8'8" shop has 5 1/2" of fiberglass insulation in the walls and 8" in the ceilings.
