When did I ever say that I didn't have a temp gun and didn't check my temps in the tubs? I said that my thermostat is set to 95 and my tubs are a few degrees less. Of course I check the temps in the rack itself.
Aside from that thanks for the clarification here. What you're saying about the UTH makes a lot of sense. I was just saying that ultimately it is up to the OP to measure temps on both sides of the tank and determine the best way to heat it accordingly depending on how much the UTH contributes to total heating (in the OP's case)
