corroded tankless water heater

A tankless heater is a great investment for any household. Not only do they provide instant hot water, but they’re also energy-efficient and save on space. However, tankless heaters, like any other appliance, can develop problems over time. Some issues may even prompt you to replace your tankless water heater.


The average lifespan of a tankless heater is around 15 to 20 years. If your water heater is approaching or exceeding this age, it may be time to consider a replacement. Even with regular water heater maintenance, wear, and tear can take a toll on your water heater. Eventually, it may become less efficient and more prone to breakdowns.

Lack of Hot Water

If you’re not getting enough hot water or the water temperature fluctuates, it could be a sign that your water heater is failing. This could be due to mineral buildup, a faulty heating element, or other issues. If you’re experiencing these problems, calling a professional for water heater repair in Fort Worth, TX is best.

However, if your water heater is too old or damaged, it may be time for a replacement.

Increased Energy Bills

If you notice a significant increase in your energy bills, it could be a sign that your tankless heater is less efficient than it used to be. As water heaters age, they become less efficient and require more energy to heat the same amount of water. Investing in an energy-efficient tankless unit on your next water heater installation can save you money in the long run.

Repairs Become Frequent

Frequent tankless heater breakdowns can be a sign of a failing water heater, and the cost of repairs can quickly add up. At this point, a tankless water heater replacement is the more efficient option overall.

With a new tankless heater, you can enjoy reliable hot water and energy savings for years. Contact Rockwater Plumbing today for all your water heater servicing needs.
