There’s nothing better than a nice, hot bath. Especially during the winter. And though Arizona doesn’t have a harsh winter, some residents will want to turn their water heater up to accommodate for the cooler temperatures or lower the temperature on your water heater during warmer months. But how high is too high? And how low is too low?

Follow these rules to make sure you’re staying in an acceptable and safe temperature range.

  • Dishwashers usually require water of at least 120°F, but can heat the water themselves if it is a newer model.

  • The Consumer Product Safety Commission (CPSC) recommends setting your water heater to no higher than 120°F for your safety and to reduce the risk or scalding.

  • During the summer, water heaters can be turned lower as the need for hot water lessens. Due to health concerns with legionella, it is important to consult a plumbing professional to make sure you haven’t reached a low temperature that would promote the growth of the bacteria.

  • Be aware of children and temperature sensitive people who can be affected raising of the temperature of your water heater.

We advise you to speak with everyone in the household to let them know you have adjusted the temperature either up or down on your water heater. The temperature of your water heater will also have an affect on your electricity or gas bill so be aware of a spike or drop in your energy costs as you adjust your water heater.
