My human heat pad gets up to 160+ at the hottest setting, if you put it on your skin you'll get a first degree burn! I've never had tubs burn or melt at that temp. The burning makes me think there is electrical issues, when you solder, 500+ degrees, the plastic doesn't burn, it melts.
If the readings all check out sounds like that could be a reason and or you have the worlds worst TUBS .
