I hate to beat a dead horse and I know this has been covered a million times but I’m conflicted on whether to put the thermo probe sandwiched between the uth and pvc or beneath it. I got thg heat tape. I got double sided tape so it adheres nicely to the bottom. My problem is that I’ve read that the probe should ideally be sandwiched but it creates a ridiculous gap and I’m guessing the heat will be inconsistent due to that.
I’m all about doing the very best and I’ve done loads of research but I think I would prefer to put the probe beneath. I would also like to use foam to insulate under the tape and probe but I’m pretty sure in the instructions it specified leaving and air gap. Anyone with experience with both methods or experience with foam beneath heat tape please give advice. Will be attaching it tomorrow and only want to do it once and done. Thanks in advance
