thought I would post a pic of my salmon hypo 04 male!!
Of course we all know to use reostats and thermostats(at least I hope we all do). However, we do not live in a perfect world and heaters have a way of going bad and raising the heat as well as just plain going out. A snake being cold blooded cannot necessarily tell in a gradual heat rise or drop. That is why we have heard so much about snake and other reptiles literally sticking to heaters and having really bad burns. Therefore, I would not put an UTH directly on the tank.
What's wrong with heat build up? Just turn your reostat down. If you have a thermostat it will adjust it for you, and your heater won't have to work as hard.
For BP_Pandora...Bee pics! :)
