Well, for you to touch something and have it be too hot(like burn you), it'd probably have to be pretty high.. maybe 200. I'm not sure about the heating requirements of a burm, but I'd say 100 in a hide is probably a bit too high. If you can, maybe put the heat pad under the tank itself instead of just under some carpet, so the heat won't be so strong.

Oh, and you posted this in the blood python forum. It'd probably go best in the giant pythons forum section.
