I know you're really worried about your little guy and just so you know he sounds similar to my little man. He constantly climbs except when in shed. If you're that worried about the RHP, maybe look into other heating solutions? I use a heat mat on a thermostat and I'm able to regulate the temps for my baby in his glass enclosure. With those nothing is in the enclosure at all so nothing he could rub against. I'm not sure totally if that would work with your setup but if you're having issues then it's time to try something new.
