Adjusting the Temperature

Because a standard water heater keeps hot water available at all times in its tank, water heaters account for about 17% of a typical home's energy use.

If you plan to be away from home for three or more days,  turn your water heater's thermostat down to the lowest setting, or turn it completely off. This will save a considerable amount of energy and cost.

​

• Electric water heater:  To turn it down, use the temperature dial on the water heater. To turn it off, switch off the circuit breaker to which it's connected.

• Natural gas water heater:  If you don't know how to relight the pilot light, just turn the temperature dial down, or switch it to "vacation mode," rather than turning it off.

When you return home, restore your water heater to the normal temperature — 120°F is sufficient for most homes.

Flushing a Hot Water Heater

Hot water tanks should be flushed regularly as part of a proactive maintenance routine. Over time, sediment, minerals, and debris from your water supply settle at the bottom of the tank. This buildup can lead to several issues, including:

​

• Reduced Efficiency:  Sediment acts as an insulating layer, making it harder for the tank to heat water effectively. This increases energy consumption and utility costs.

• Shortened Lifespan:  The accumulation of debris can cause the tank to overheat or corrode, leading to premature wear and potential leaks.

• Inconsistent Hot Water Supply:  A tank clogged with sediment may struggle to maintain a steady flow of hot water, impacting your daily routines.

Flushing your hot water tank helps remove sediment, improves energy efficiency, and extends the life of your water heater.
