I have a 480 sq ft insulated attached garage that is heated with a propane ventless wall heater. It maintains 60 degrees on the lowest setting. Because of the heater being ventless the humidity is always above 50% in the space. The heating cost is around $150 a season. Propane cost this year is $1.99 a gal. The efficency level is somewhere around 99%. Perfect for tinkering with the Vette.
Just paid $4.05 gal. for propane for my house in upstate N.Y.
I have an attached insulated garage and put in a Mr. Heater Natural Gas Garage Heater. I used the 45000 BTU unit but for yours I would suggest the 75000 BTU one. They work very well! http://www.northerntool.com/shop/too...6363_200316363
When I lived in Chicago last house had attached 2 car garage. I insulated walls with foam sheets and put in a thru the wall ventless furnace. Ran a gas line and kept on lowest thermostat setting until I worked out in it. Could wash my cars all winter long. No duct work reverse flow which means hot air from bottom. No standing pilot and sealed combustion chamber, no worry of igniting fumes. Williams was brand in Grainger catalog.
Clif has the best cheapest way to heat something quick without doing a install in your shop. Those things work.
Little Offshore fishing trick we use when like now its in the low 20's and we want to fish.
Standard lowes milk crate we all have or had at one time. A 20 pound cylinder of gas will slide right in it and a one to two IR burner from lowes. Have curtains on the boat but it takes about 5 minuets and we're coming out of coats. Shop I"m sure would take longer but my vote on quickest and best way goes to clif's thermoheat blower.

My garage is 24 x 36 feet, insulated and sheet rocked. I have a wall mounted 30,000 btu propane heater and keep the garage temperature about 50*. It feels a lot warmer than my stinkin house. The garage is also separated from the house by a hundred feet. I did that so I could work out there late at night and not keep the wife awake. Have hot and cold running water, cable tv and phone. All I need is a portable toilet.
My garage is fairly large with concrete block walls and no insulation on walls or ceiling. I think that's all that's keeping me from installing heat of some kind. But it's so close to spring now, I'm gonna wait a while. I discovered a large wood burning stove my late father in law stored in my barn and I'm thinking about using it. My garage already has a chimney flue/chimney built in. Only catch there I guess is using garage space to keep my firewood out of the weather.
