Understanding Your Water Heater's Lifespan
Most conventional tank water heaters last 10 to 15 years, but the actual lifespan of yours depends heavily on water quality, maintenance, and installation quality.
What Shortens Lifespan
Hard water accelerates scale buildup inside the tank, and a neglected anode rod lets corrosion attack the tank itself instead of the sacrificial rod designed to take that damage.
Signs of Approaching Failure
Rumbling or popping sounds during heating, rusty water, and a tank nearing the 10 to 15 year mark are all signs to start planning for replacement before an emergency forces the decision.
Repair or Replace
A failed heating element or thermostat on a newer unit is usually worth repairing. A tank over 12 years old showing corrosion is usually better replaced, since the tank itself can't be repaired.
