I have a UTH on the hot side that is regulated by a thermostat. I currently have the thermostat taped under the tank right next to the UTH, but would love a good explanation of how that probe should be affixed (an image would be even better). The thermostat is set at 87 degrees and is currently reading 87.2 degrees. The thermometer is reading 93.2 degrees. That makes me think that my problem is in the location of the thermostat probe.
