How to Extend Your Water Heater Lifespan

Water heaters are a quiet workhorse in most homes, often out of sight and out of mind until something goes wrong. With a regular maintenance routine, you can extend their life, improve efficiency, and avoid unexpected outages. Below are practical steps that homeowners can take without needing specialized tools.

Key maintenance steps

1) Test and maintain the thermostat setting. Keeping water around 120°F helps reduce energy use and minimizes mineral buildup. If you have a tankless model, follow the manufacturer’s recommended temperature range.

2) Drain and flush the tank at least once a year. Sediment from hard water accumulates at the bottom of the tank, reducing efficiency and shortening life. Attach a hose to the drain valve, drain a few gallons, then close and refill the tank.

3) Inspect the anode rod and replace as needed. The anode rod prevents tank corrosion; if it’s heavily corroded or coated with calcium, replace it to protect the interior.

4) Insulate the heater and nearby pipes. Wrapping the tank with a proper jacket and insulating exposed pipes reduces heat loss and energy costs, especially in colder climates.
