I hope for the fuscus' sake that the enclosure was only used as an interim measure & the CHE wasn't used. Although I have been guilty of using a CHE (appropriately caged) for my hatchy, with the knowledge I have now, I don't bother using CHE's for even juvenile snakes depending on enclosure. It's merely a waste of energy, low wattage heat mats/cords are so much more effective & efficient.
