In the future, if you want to reuse your UTH, you can always tape up the sticky part, then tape the rest of it to the bottom of your tank -- with ALUMINUM FOIL TAPE, of course!
It's fire retardant, and allows most of the heat to come out fine (mine still got up to 114F, when I let it go without a thermostat before I got the BP).
I folded over the edges of the tape so that I can gently pull it off when I move my snake to a larger enclosure.
