You can stick the UTH right on it, you can use heat tape, or you can use heat mats (cobra, etc) since they can be removed easily. YOu will need to control these with a dimmer/rheostat so they don not get too hot. I would recommend avoiding the use of human heat pads. They have the built in convenience of settings, but they are more of a fire hazard. Many people have used them for years with no subsequent problems, but some have lsot their homes and collections to them as well. The fact remains that they were not designed to be left on 24/7.
