Ok so I just noticed that when I use a temp gun and check the heat tape it says 91*F but when I check inside the tub on the hot spot its 94-97*F.
I also noticed that on the same strip of heat tape in one spot its 94* and on the other side it was 104*!
Does this mean the heat tape is bad? Or the thermostat? Im currently using a Repstat Digital Thermostat set to 90* but most of the hot spots in my tubs are 95*?
Is this bad? The Room temperature is a constant 80*F. Any help is appreciated, thanks.
