So the temperature here is setting, let's put this to one 20. Sometimes you'll have a letter A, B, or C, and you'll have to figure out which one that is. Let's take a look at the installation. I'll take a look at the lower thermostat. And so this is set a little bit higher than the upper thermostat, so this person actually has hot water at too high of a temperature.
The temperature of the tank is 140 or slightly more degrees, so this water's actually a little too hot. So here's what you would do now. You would set the water heater, run some of the water outta the tank, let it cycle back on, and then measure the water temperature.
