Life Cycle of a Water Heater by Paradise Plumbing & Gas

Posted on April 17, 2016

Based on the manufacturer's suggested service life, the life expectancy of a water heater is between 5 to 10 years. That varies with the location and design of the unit, quality of installation, maintenance schedule and water quality.

The manufacturer's tank warranty is a good guideline to use as far as life expectancy is concerned. A tank with a five year warrant should last five to six years, without preventive maintenance. Up to ten years if you keep the sediment flushed out and replace the anode rod as necessary.

If your water heater is more than 10 years old, it leaks around the base of the tank, works erratically or not at all, it's probably time for replacement. Check if an electrical problem, such as a blown fuse or tripped breaker, is not the reason for the unit's failure.

The most common problem connected with a water heater is water that isn't as hot as you want it to be. This is often caused by a faulty thermostat or a defective heating element. These parts can be repaired and replaced.

Tank failure is the main reason to replace a water heater. Excessive sediment, high heat and pressure over a period of time will cause the inner liner to crack. Once the liner is compromised, water comes in contact with the steel tank, the tank begin to rust and eventually the tank will began to leak or even burst.
