Depends how much insulation you have in the floor, walls, and ceiling. But I would say that is about the right size if your house is decently insulated. Do yourself a favor though and get a computer fan or two with a 12 volt deep cycle to move the air in there.

I second the fan idea. Also, be sure you have adequate venting, maybe some adjustable vents or at least a window you can open slightly. This is for you to be safe in there overnight from the carbon monoxide, which may or may not be a threat, but better safe than sorry on this one.
