Like any hardworking appliance, gas water heaters won’t last forever. But how much can you realistically get out of them before it’s time to upgrade to a new one? Well, the short answer is it depends. On average, a gas water heater lasts eight to 12 years, though there are a variety of factors that can either shorten or extend that lifespan. In this blog, our team at Eagle Air Conditioning covers what factors to keep in mind, how to get the most out of your gas water heater, and signs that point to needing to replace it with a new one.
Factors Influencing the Lifespan of a Gas Water Heater
Not all gas water heaters age the same way. Whether yours will need replacing sooner rather than later will depend on several factors. Here’s what to consider:
Usage Frequency
The more hot water your household uses, the harder your water heater has to work. Large families that run showers, dishwashers, and laundry multiple times a day will see more wear and tear than a single-resident home with minimal water usage.
Water Quality
California’s Central Valley has hard water, meaning it contains high levels of minerals like calcium and magnesium. These minerals can build up in your tank over time, which reduces efficiency, shortens your unit’s lifespan, and increases energy costs.
Tank Material & Build Quality
Not all water heaters are built the same. Some models feature glass-lined tanks and corrosion-resistant materials, giving them a longer life expectancy. Investing in a durable, well-built unit can mean fewer headaches and more years of reliable hot water access.
Installation & Ventilation
Improper installation can lead to efficiency issues, overheating, or even dangerous gas leaks. If your home is older, you may want to consider updating the plumbing or ventilation to better accommodate a new water heater.
How To Extend the Life of Your Gas Water Heater
While we recommend leaving more complex maintenance to the professionals, there’s plenty you can do to keep your gas water heater in top working condition — all without needing expert knowledge. Here are a few simple ones you can DIY without a problem:
- Flush the tank annually: This helps to remove sediment buildup in the tank, maintaining its performance and preventing overheating.
- Check for leaks: Regularly inspect your water heater and surrounding pipes for leaks. Catching small drips early can save you from bigger, more expensive repairs down the road.
- Test the pressure relief valve: This valve prevents excess pressure buildup inside the tank. Testing it annually ensures it’s working properly and prevents potential damage.
- Inspect the anode rod: This rod protects your tank from rusting. If it’s worn down, replacing it can help extend your water heater’s lifespan significantly.
- Adjust the thermostat on the water heater: Keeping the temperature at 120 degrees Fahrenheit reduces wear on your system while ensuring you still get plenty of hot water.
Signs Your Gas Water Heater Needs Replacement
As mentioned earlier, no water heater lasts forever, even with consistent maintenance. Keep an eye out for these warning signs that it’s time to replace your unit:
- Discolored or odd-tasting water
- Puddles forming around the unit
- Inconsistent or no hot water
- Banging, rumbling, or other strange noises
- Unit is over 10 years old
