How long has it been set up?

Remember, it may take a few hours to heat up evenly and stabilize. Remember its got to heat up any thermal mass inside the tub - newspaper, hides, waterbowls, whatever else - so until then, you are going to get wierd temp readings on the stat and in the tub. Just give it some time.
