At very least insulate the edges with rigid foam.
Several feet in form the edges is the next step
Preferred would be under the entire slab with 2 inches of foam.
You will pay for it as insulation or fuel

Alfalfa,
Why not use the InsulTarp and do a radiant floor heat?
ART's Mark Ross has a neat "Plug & Play" system that is very user freindly. They are heating a 6,000 sq ft training facility with radiant floor heating using only a 34 gal hot water heater!
Contact him.......http://arit.com/

Be sure to use vertical insulation around the perimeter of the building as a minimum. Horizontal insulation across is absolutely required if you have a high water table (the water will carry away your heat). If you do not have a high water table, I suggest horizontal insulation at least four feet in all the way around the building. This way, the heat has to travel into the ground, travel out four feet, then back up and out. Insulation all the way across the floor will increase efficiency, but the incrimental increase has a long payback period.
