A thermostat is located in the lower portion of the water heater. has a dial on the front. When adjusting a thermostat on a water heater, things to keep in mind are the different settings. You have a cool, a hot and a hotter settings or ABC. Typically, there's preset at one setting. You can adjust them a little hotter. A little cooler for different temperatures. Sometimes as thermostats get a little older, they need to be adjusted up just a little bit. if you have small children at home, make sure you keep that in mind when adjusting that thermostat. On your water heater, there is a vacation mode, rotate the knob into vacation if you're going to be gone for more than a week at a time. I'm Terry with Towers Murray Plumbing, Murray, Utah.
