Where should the temperature setting be set for a residential water heater?

The optimal temperature setting for a residential water heater is generally recommended to be 120 degrees Fahrenheit. This temperature strikes a balance between providing sufficient hot water for everyday use and minimizing the risk of scalding. Water temperatures above this level can cause burns, especially in children and the elderly, so setting the heater to 120 degrees can help prevent these accidents.

In addition to safety, setting the temperature at 120 degrees also helps enhance energy efficiency, as higher temperatures lead to greater heat loss from the tank and increased energy consumption. Most plumbing and safety organizations endorse this temperature level for residential use, ensuring that homeowners can enjoy hot water without excessive risk or energy waste.
