I would love if someone could help me in figuring out why my UTH isnt getting hot enough or how to fix this problem. I'm using a plastic tub enclosure. I'm using a zoo med UTH which is under the plastic tub. I am using a tsat and I have the probe under heath the UTH to of course get the most accurate temp. I do have a digital reader for my humility and temp also and that probe is inside the tub under the paper towels. I am using paper towels as my substrate. I am also using a temp gun as my temperature reader. I have my tsat all the up to the max of 108° but his hot side only goes to 85° Could I get some help in trying to figure out what is it that Iam doing wrong? Or how to fix this. Especially since it's about to be winter. I dont want my BP to be freezing to death. Should I buy a new UTH?
