So as long as I'm using a thermostat and the temps don't get above 92 degrees, the UTH on plastic should be safe?

Thank you for the help. What will the foil tape do? (I don't know much about this kind of stuff.)

^There is concern on that thread about a UTH on plastic causing a house fire. Is that true? Is it because it's a UTH on plastic, or because any unregulated UTH (no matter what it's on) is dangerous?
