Regular maintenance is key if you want to get the most out of your water heater. By embracing energy-saving habits, you’ll not just cut down on utility bills but also maximize your water heater’s lifespan.

At Mr. Rooter Plumbing, we have helped countless customers save money by finding the right water heater and sharing best practices for extending a water heater’s lifespan. As the plumbers to call for water heater repair, we know what goes into saving energy and extending water heater life. In this post, we’ll share energy-saving habits that can extend water heater life.

  • Lower the Temperature Setting

Many water heaters are preset to 140°F, which increases energy use and accelerates mineral buildup. Lowering your thermostat to 120°F provides sufficient hot water for daily needs, prevents scalding, and reduces strain on the system.

  • How To Adjust the Temperature on A Water Heater

For an electric water heater, first turn off the power at the breaker panel to prevent electric shock. Then, access the thermostats and use a flathead screwdriver to set the thermostat dials. If you have a gas water heater, find the dial at the bottom of the tank and set it to your desired temperature. Wait several hours and test the temperature using a digital thermometer held under running hot water. If the temperature still doesn’t match your target, you may have to call a nearby plumber to inspect your water heater and make the necessary repairs.

  • Flush The Tank Annually

Depending on the quality of your water supply, sediment and mineral deposits can accumulate at the bottom of the tank, creating an insulating barrier between the heating elements and the water. The consequence of sediment buildup at the bottom of the hot water tank is that the system will have to work harder to heat water. The unit will consume more energy and hike your utility bills.

The best way to deal with this situation is to flush your hot water tank at least once a year to keep the heating elements clean. This will not just enhance heating efficiency, but it will also extend the lifespan of your water heater. In addition, you’ll get cleaner and better-quality hot water.

Signs Of Sediment Buildup in Water Heater

  • Rumbling or popping noises
  • Fluctuating water temperatures
  • Longer heating recovery times
  • Discolored hot water

Note that some of these signs can point to other issues with your water heater apart from sediment buildup. If these issues persist after flushing your hot water tank, get in touch with a local plumbing repair service for an inspection. Timely water heater repair can also help to save energy and prolong the system’s lifespan.

  • Insulate the Tank and Pipes

This applies to traditional storage water heaters. Proper insulation minimizes heat loss, meaning your heater doesn't have to work as frequently to maintain water temperature. Wrap older tanks with a water heater insulating blanket and cover the first six feet of exposed hot water pipes. A reliable plumbing repair service provider can help you choose the most effective insulation materials for your hot water tank.

  • Check the Anode Rod

Often called the "sacrificial rod," this component attracts corrosive elements in the water so they don't attack the steel tank itself. Inspect the rod every 1 to 2 years and replace it when it's corroded to prevent your tank from rusting. Let a professional plumbing service provider help you with anode rod replacement.
