How Long Do Tankless Water Heaters Last? Lifespan & Ways To Extend It

Keep Your Tankless Water Heater Running Efficiently

Tankless water heaters are becoming an increasingly popular choice for homeowners. This speaks to the efficiency, reliability and space-saving design that comes with these systems. However, many homeowners wonder how long these systems last compared to traditional water heaters and how they can ensure their unit runs smoothly for years to come.

At Mission Air Conditioning & Plumbing, our team is here to help guide you to an answer.

How Long Does A Tankless Water Heater Last On Average?

A tankless hot water heater can usually last anywhere between 15 to 20 years. This is longer than the typical tank-style water heaters, which often last around 10 to 15 years. Tankless systems are known for their durability, as they don’t experience the same wear and tear from constantly heating a large tank of water.

Electric Tankless Water Heater vs. Gas Tankless Water Heater Lifespan

When discussing the lifespan of a tankless water heater, it’s important to note the differences between electric and gas-powered models. Both types of tankless systems have similar estimated lifespans. However, there are subtle distinctions between the two.

Electric tankless water heaters tend to have fewer moving parts and may require less maintenance, but their lifespan can be slightly affected by water quality and the minerals in your water. Gas-powered tankless systems, on the other hand, have a slightly more complex mechanism, which can lead to a bit more wear and tear over time. Proper venting and maintenance are key to ensuring they reach their full lifespan.

Factors That Affect Your Tankless Hot Water Heater

While tankless water heaters will often last longer than traditional systems, several factors can affect their lifespan. Be mindful of the following in order to stay ahead of any water heater concerns.

Water Quality

One of the biggest contributors to premature failure in tankless systems is the presence of hard water. In areas with high mineral content in the water, scale buildup can accumulate on the heating elements, which decreases efficiency and could lead to failure if not properly maintained.

Usage Levels

Homes with multiple occupants or high hot water demand may see their water heaters working harder, which can lead to increased wear. However, tankless systems handle demand better than traditional ones, and they typically still perform efficiently for many years.

Installation Quality

Proper installation is a crucial part of maximizing the lifespan of a tankless water heater. When the unit is installed correctly, it operates efficiently and reduces the chances of experiencing issues. It’s essential to have a professional, like Mission Air Conditioning & Plumbing, handle the installation to avoid mistakes that could cause damage down the road.

Maintenance Patterns

Just like any other appliance in your home, regular maintenance is essential for ensuring your tankless water heater performs at its best. This includes descaling and annual check-ups to catch issues early and prevent them from turning into major problems. By ignoring maintenance needs, you could be putting your water heater at risk.

How To Extend The Lifespan Of Your Tankless Unit

To get the most out of your tankless water heater, it’s important to follow a few key maintenance practices:

  • Regular descaling — This process involves removing mineral deposits (scale) that accumulate on the heating elements. Descaling should be done at least once a year, or more often if you have very hard water.
  • Professional maintenance — A trained technician will clean the unit, check for potential issues and make any necessary repairs to keep the system running smoothly.
  • Ensure proper ventilation — Tankless water heaters require good airflow to function correctly. Be sure that the venting system is clear and free of obstructions, and regularly inspect it for any damage.
  • Keep an eye on temperature settings — It may be tempting to turn up the temperature on your tankless hot water heater, but setting it too high can put excessive strain on the system.

Know When To Replace Your Water Heater

Even with proper care, every appliance has a lifespan. If you notice that your tankless unit is no longer providing consistent hot water, frequent repairs are needed or your energy bills have risen significantly, Mission Air Conditioning & Plumbing can help you consider your replacement options.
