Regular Inspection and Maintenance
The cornerstone of extending the life of any appliance, including your home’s water heater, starts with regular inspection and maintenance. A once-a-year comprehensive check by a professional can catch any concerns early on, such as leaks or corrosion. While homeowners can perform basic checks, a qualified technician will have the expertise to conduct a more thorough inspection and carry out necessary preventative measures.
These annual inspections should focus on key components such as the anode rod, which protects the tank from rusting, the pressure relief valve, which ensures the tank isn’t subject to dangerous levels of pressure, and the thermostat settings, which should be correct for efficiency and safety. Homeowners should also stay alert for any unusual noises, which could indicate sediment buildup or other issues requiring attention.
Consistent Temperature Settings
It isn’t just comfort that is affected by the water heater’s temperature settings—it’s also the longevity of the unit. Keeping the temperature set at a consistent 120-130 degrees Fahrenheit can prevent overheating and undue stress on the system, while also saving energy. Temperatures higher than 140 degrees Fahrenheit not only pose a scalding hazard but also accelerate the corrosion of internal components, thereby reducing the lifespan of the heater.
Beyond preventing wear and tear, consistent temperature settings also ward off sediment buildup. This is because high temperatures cause minerals in the water to solidify and collect at the bottom of the tank faster. Regularly checking and maintaining the set temperature will help ensure that your water heater operates efficiently and lasts longer.
Addressing Sediment Buildup and Flushing the Tank
One of the most common issues that water heaters face over time is the accumulation of sediment at the bottom of the tank. This sediment, primarily composed of calcium and magnesium, can insulate water from the burner or heating element, reducing efficiency and forcing the heater to work harder. If left unchecked, this can lead to overheating and tank damage.
To combat sediment buildup, homeowners should drain and flush the tank at least once a year. By attaching a hose to the drain valve and releasing a few gallons of water into a bucket, one can often remove a good deal of this sediment. In areas with particularly hard water, flushing the tank more frequently may be advisable.
Insulating Older Water Heater Units
For older water heater units, adding insulation can improve efficiency and reduce the strain on the system. By wrapping the tank in an insulation blanket and insulating the pipes, heat loss can be minimized, allowing the unit to maintain the desired water temperature with less energy. Insulation is an inexpensive method to prolong the life of the heater by staving off wear and tear on the system.
It should be noted, however, that newer water heaters tend to come with sufficient built-in insulation and often do not require additional insulating materials. For safety, it’s essential to avoid insulating the top of a gas heater or blocking the thermostat of an electric heater.
Preventive Replacement of Parts
Instead of waiting for a catastrophic failure, replacing worn parts preemptively can be a smart way to extend the life of your water heater. This includes periodically replacing the anode rod before it’s entirely corroded. The anode rod attracts corrosive elements in the water and is designed to corrode in place of the tank. Once corroded, it stops providing protection, leaving the tank vulnerable to rust and leaks. Curious to know more about the topic?

Other parts that may need attention over time include the pressure relief valve, heating elements, and thermostats. By keeping these components in good working order with preemptive replacements as needed, you can avoid more significant, costly issues down the road and help ensure your water heater remains operational for its full expected lifespan.
