I get “hot spots” along areas of my heat tape despite what the tstat is set at. However, I’ve been in contact with Spyder Robotics who have told me I should consider swapping out my heat tape. One main reason is because the heat tape is old ( 10years) or more. Previously I was resetting the tstats ( all Herpstats)and that has helped to a degree. ( No pun intended) Lol. Seems that it happens more after a power outage which has been a common occurrence here in Virginia and this neck of the woods.
To lessen the risk of injuries to my reptiles or even a fire I now have a new project to change out all the old heat tape.![]()
