My garage has an insulated ceiling, but the walls are uninsulated and the door is an uninsulated metal garage door. The room is approximately 400 square feet. I'm looking at installing a vent-free natural gas heater that puts out 30,000 BTU's and is rated to heat up to 1000 square feet. I know that the square-feet ratings are on the generous side and is probably a well insulated 1000 square feet. Since my garage has uninsulated walls and an uninsulated garage door, will a heater rated for 1000 square feet be sufficient to heat my 400?
Will 30,000 BTU's effectively heat my garage?

If your garage is fairly "tight" (draft-free) you ought to have no problem heating it with a 30K BTU heater. I used to heat a 2-car garage workshop with a kerosene heater rated at 25K BTU. My only concern would be whether or not your garage is attached to a living space. Vent-free appliances are notoriously dangerous and should not be used anywhere the combustion gasses might infiltrate living spaces. Here's a good read on the dangers of vent-free appliances: http://www99.epinions.com/content_3679363204

Without a doubt. It will not only heat it but will be efficient because it will heat it quickly and run less cycles. Consider a portable humidifier if you plan to spend time in there. It will make it more comfortable and save a little on fuel.
