Water heaters are an essential part of homes here in Idaho and across the country and world. However, like all appliances, they have components that wear out over time—one of the most important being the heating element. If you’re wondering how long a typical water heating element lasts and what factors influence its lifespan, this article will provide you with the answers. Gem Heating & Air Conditioning is a trusted source for water heater repair and replacement services in the Treasure Valley.
Average Lifespan of a Water Heater Element
In most residential water heaters, the heating element lasts between 6 to 12 years. However, this can vary based on several factors, including the type of water heater, water quality, maintenance habits, and overall usage.
Factors That Affect Heating Element Lifespan
-
Water Quality
Hard water, which contains high levels of minerals like calcium and magnesium, can lead to mineral buildup on the heating element. This buildup (also known as scaling) reduces efficiency and can cause the element to burn out prematurely. -
Usage Frequency
A household that uses large amounts of hot water daily will put more strain on the heating element compared to a home with minimal usage. The more frequently the element cycles on and off, the faster it wears out. -
Tank Maintenance
Regularly flushing the water heater tank to remove sediment buildup can extend the lifespan of the heating element. If sediment accumulates at the bottom of the tank, it can cause the element to overheat and fail. -
Voltage and Power Surges
Electrical fluctuations or power surges can damage the heating element over time. Using a surge protector for your water heater can help prevent premature failure. -
Quality of the Heating Element
Some water heaters use low-quality heating elements that are more prone to failure. Upgrading to a high-watt-density or low-watt-density element made from durable materials, such as stainless steel or Incoloy, can improve longevity.
Signs That Your Heating Element Needs Replacement
If your water heater’s heating element is failing, you may notice:
- Water taking much longer to heat up
- No hot water at all
- Inconsistent water temperature
- Higher energy bills due to inefficiency
- Strange noises (popping or hissing) from the heater
How to Extend the Life of Your Water Heater’s Heating Element
- Flush the tank annually to remove sediment buildup.
- Install a water softener if you have hard water to minimize mineral deposits.
- Check the anode rod regularly and replace it if it’s heavily corroded.
- Use a surge protector to prevent electrical damage.
While the average heating element lasts 6 to 12 years, proper maintenance can extend its life. If your water heater isn’t performing as expected, checking the heating element should be one of the first troubleshooting steps. Regular upkeep will ensure your system runs efficiently and provides reliable hot water for years to come.
