How to Extend Your Water Heater Lifespan

A typical tank water heater lasts about 8–12 years, but proactive care can push that timeline further. The goal is to minimize sediment buildup, reduce corrosion, and prevent unnecessary strain on the tank and heating system.

Flush the tank regularly

Over time, minerals settle to the bottom of the tank and form scale. This reduces heating efficiency and can cause overheating. If you have a standard tank, flush it periodically—often every 6–12 months—especially if you have hard water. A simple drain-and-rinse approach helps remove sediment before it thickens.
