I'd like to go the electric route. After some searching, it seems like a bunch of people are using this Dayton G73. It produces 17k BTUs at about 5000 watts. 240 supply.

My garage is about 500 square feet.

I could probably help you size one up if you like. I'm a sales engineer for an electric heating company. How high are your ceilings? Is the garage insulated? General rule of thumb is about 2 watts per cubic foot on a well insulated structure. That's for a 70* delta T, so maintaining 70* on a 0* day so you could probably get away with less in a garage.
There's a chart on the second page of this PDF that will help you out. Let me know if you have any questions. Our units are unfortunately more expensive than the Dayton unit because we're geared more towards the industrial market, but I'd be happy to help out a fellow car guy either way.

Cool stuff.

I'd wait to see what happens with the energy caps coming off this january before buying that heater. It might be REALLY expensive to run if our electric bills skyrocket. .02

Supercomp c4, some other things, hoping to run 10's...update 10.50@120 on 8 burned pistons...hoping to run 9's no cage in sight
I've been trying to figure out the best way to heat my garage as well. It is 30'x52' with 14' high ceilings. It is block with 2" foam on the ceiling.
That would take a lot of wattage from an electric heater. You're probably looking at about 40kW(136,600 BTU's). There are plenty of units out there that can do it, but it might draw more Amps than you have available. At 240V single phase you're looking at about 166 Amps.Originally Posted by cam303

Stud the walls and insulate....or see if you can dump vermiculite down in the walls from the top. Without insulation it's too expensive to heat.

we sell alot of used oil fired mobile home furnaces for garages. They don't take alot of room up, and are downflow, so you can set them up on blocks and they blow the heat out of the bottom which heats up the lower portion (where you are normally working) of the garage quicker than an upflow model does.
