As water heater specialists in the greenwood, IN area, we are often asked, “What is the typical lifespan of a water heater and how do I prolong the life of mine?”
Although not very common, water heaters can sometimes last up to 15 years, sometimes eve as much as 20 years. A standard water heater will last you somewhere between eight and twelve years. The majority of water heater tanks today are steel, lined with a type of glass or porcelain. Over time, most water heater tanks will oxidize and deteriorate producing a small leak in the tank – in some cases a disastrous leak. For this reason it is important to know where the water shutoff valve is located.
Keep in mind that most water heaters decrease in efficiency as a result of sediment build-up, even if it is still working.
Tankless water heaters can last 2 to 3 times longer than the traditional tanks, provided you care for the unit properly.
Ways to Help Prolong Your Water Heater’s Useful Life
A few things that can extend your water heater’s life:
- Install an Expansion Tank: When water is heated from 50º to 120º, it expands. If your system is closed (a valve which prevents your water from back flowing into the water main), this water has nowhere to go. Because water is not a particularly compressible material, it will cause rapid increases and decreases in water pressure. This expanding and contracting causes stress on both your water heater and your plumbing system which can cause damage and even premature failure. Installing an expansion tank can potentially double the life of your water heater
- Clean or flush out the tank: For older tanks, flushing out the tank annually can help prevent sediment buildup and helps maintain an efficient tank for longer. Newer model water heaters are self-cleaning.

- Install a Pressure Regulating Valve (PRV): High water pressure (above 90 PSI) can damage your appliance and can also cause your water heater to prematurely fail. The PRV will reduce the system pressure. It is recommended to install an Expansion Tank if you have a PRV
- Install a water softener: Water with high concentrations of minerals (commonly known as “hard water”) causes scaling – a precipitation of minerals deposited onto surfaces of an appliance. Scaling reduces the efficiency of the appliance and can increase the use of electricity.
When To Call In The Professionals
If you have any of the following problems with your water heater, it probably means that your appliance is simply worn out and it is time for a replacement:
- Cracks, leaks or rust on the tank
- Rust in the water
- Smelly water (smells like sulfur or rotten eggs)
- Unusual noises coming from the water heater or adjacent pipes
We strongly caution against trying to install a new water heater yourself. This will often void your warranty and could be just plain dangerous!
