I'm currently using a couple propane heaters and a kerosene heater for spot heat, and if I use them long enough in the same bay it does heat the bay up a bit.

I have a wood stove in the corner that I've yet to hook up, need to see what my homeowner's insurance says about that. This will probably be the slam-dunk option if feasible, as I have ~10 cords of firewood already and unlimited access to as much as I'm willing to haul, for free. If it was ONLY a danger to my shop I'd probably just install it and accept all liability, but my house and my neighbor's houses are close enough that it's not worth the risk without insurance backing me up. I also want to make sure my neighbors don't mind the smoke, although I and half the other houses in the neighborhood burn wood to heat our homes.

I have 240v power available, a 5kw electric heater would be an option, although that's under 18k btu's. Not much for this application.

Current cost/BTU in my area from best to least would be:

Wood stove(just time/labor........hah "just")
Pellets 66k btu / $1
Diesel 57.5k btu / $1
Propane 50.5k btu / $1
Kerosene 35.5k btu / $1
Electricity 26k btu/ $1

If the wood stove is a no-go, I'm leaning towards a CL pellet stove based on the above list, as long as that will clear insurance.

Any other ideas? Thanks all.
