Here's another idea, We use this as a backup heat source in our wet bay in case the furnace that heats it quits. Heads up though. This one uses more power than Don's idea. It is a Magnetic block heater and will need a metal surface to attach to. It uses 2 amps (200 watts) and uses the metal it is magnetically attached to to radiate the heat. Never hot enough that you can't touch the metal though. Here'a picture, followed by a link to a supplier.
