I recently came across these wall heaters and they are absolutely amazing. They are a great alternative to standard furnaces. Why heat the entire home if you are only hanging out in one room. I think I am going to pick up a heater for my dads garage as a gift, I know he will love it. They carry both Natural gas and Propane heaters and these things are dirt cheap. They have a great looking diamond plate heater that I would love to buy for myself. Take a few minutes and go over what they have to offer, you will be amazed at how cheap these are and how efficient.
