If your basement has a wet bay hole for hoses, television cords, plug it up and and just use a 40 watt lightbulb in there. We were in a NC campground during the winter of 20 while our home was under construction. Had many mornings 12-15 degrees not getting above freezing all day.
Referring to the clarification, and the several clarifications of the clarification - it's clear he is not talking about the basement, he is indeed talking about the garage; and surely, a 40W light bulb will not heat the garage.
