How Long Does a Water Heater Last?

November 2, 2023

Have you ever paused to consider the unsung hero of your daily routine—the water heater? It quietly operates in the background, faithfully delivering hot water for your morning showers, dishes, and laundry. However, like all good things in life, even the most reliable water heaters have a finite lifespan. 

From the basics of water heater technology to tips on extending its lifespan, Ultimate Air will be sharing everything you need to know about your water heater’s lifespan. Let’s dive in and discover the key factors that influence the longevity of your water heater and ensure that your hot water supply remains uninterrupted for years to come.

What is the Average Lifespan of a Water Heater?

The average lifespan of a water heater can vary depending on several factors, including the type of water heater, the quality of the unit, the local water quality, and maintenance. On average, you can expect the following lifespans for different types of water heaters: 

  • Traditional Tank Water Heaters: These are the most common type of water heaters. On average, they tend to last around 8 to 12 years. With proper maintenance, you might be able to stretch their lifespan towards the longer end of that range.
  • Tankless Water Heaters: Tankless water heaters are known for their longevity. They can often last 20 years or more, primarily because they don’t store water and are subjected to less wear and tear.
  • Heat Pump Water Heaters: These energy-efficient units typically have a lifespan of around 10-15 years. However, their energy-saving features can help offset their initial cost.

It’s important to note that water heater lifespans can be influenced by local water quality. Areas with hard water (high mineral content) may experience shorter lifespans due to mineral buildup, which can be mitigated through regular maintenance.

How to Maintain Your Water Heater for a Longer Lifespan

Proper maintenance is essential for extending the lifespan of your water heater. Here are some tips on how to maintain your water heater to ensure it operates efficiently and lasts longer:

Regular Flushing

Sediment buildup, particularly in tank-style water heaters, can reduce efficiency and shorten the lifespan of your unit. Periodically, drain and flush your water heater to remove sediment. Here’s how to do it:

  • Turn off the power or gas supply to the water heater.
  • Connect a garden hose to the drain valve at the bottom of the tank.
  • Open the valve and let the water flow into a bucket or drain until it runs clear.
  • Close the valve and disconnect the hose.
  • Turn the power or gas supply back on.

Check and Replace Anode Rod

An anode rod is a sacrificial component that helps prevent corrosion inside the tank. Over time, it can deteriorate. Inspect the anode rod annually and replace it if it’s significantly corroded. Most anode rods should be replaced every 2-5 years.

Set the Correct Temperature

Keeping your water heater’s temperature too high not only poses a scalding risk but can also accelerate wear and tear. Set the temperature to 120°F for energy efficiency and safety.

Inspect for Leaks

Regularly check for any signs of leaks around your water heater, including at the pressure relief valve, the connections, and the tank itself. Address any leaks promptly to prevent damage and water waste.

Schedule Professional Inspections

It’s a good idea to have a professional inspect your water heater periodically, typically every 1-2 years. They can check for any issues you might have missed and provide expert guidance.
