I didn't want to start another "Heating" thread, so I figured I'd bump this one on up.

Anyway, I've made the decision to set my tank up with paper towels instead of calci-sand or carpet, but I started thinking about how to heat the tank. Originally, I was going to use the ZooMed UTH that's already stuck to the bottom of the tank, which would have been fine were there sand on top of it. Now, I notice how HOT the glass gets directly above the UTH without a thick layer of substrate to disipate it - how am I going to do this with paper towels without scorching the Leo's belly? Would an overhead lamp be better, or am I overreacting to the heat's possible effects on the paper towels? I haven't measured the temp directly on the glass, though it's too hot to leave my bare hand on for too long.
