Way off-topic.

I'm really having trouble finding anything on the internet for heating a large workshop. I've found some used-oil heaters but won't have enough used oil to rely on that and they're quite expensive. Am thinking I might want to use mostly wood heat (as in a large house furnace?) and use the used-oil heat as a supplement.

Anyone have any ideas or links?

The area I'm wanting to heat is 7200 sq ft or a little over 120k cubic feet. I can't even find reliable figures on how many BTUs I need for it. I'm getting anywhere from 100k to 500k. I do know that my portable 150k kerosene heater, running on diesel, is enough to knock the chill off and maybe give a 1-2 degree rise per hour when it's 35 degrees out.
