Signs That Your Tankless Water Heater Needs Replacing

Tankless water heaters have a lot to recommend them. They are energy efficient, space efficient, and can last a good long time with proper care and maintenance. However, they are not perfect systems. You’re going to need to replace your tankless water heater system sooner or later, no matter how well you take care of it. Since you probably don’t want to find out that your water heater is failing in the middle of a shower, you should keep an eye out for the signs that your system is nearing the end of its life. That way, you can replace it before it fails completely. Let’s take a look at some of those signs now.


Tankless water heaters are manufactured to last between 10 and 15 years. Past that point, they start to develop serious issues and cost more and more to keep running. You can try to keep your aging tankless water heater alive past that point, but it would in all likelihood be cheaper to replace it with a new model.

Loss of Efficiency

Any water heater system can be overwhelmed if enough demand is placed on it. If you’re only putting moderate demand on it and it’s still not keeping up, however, that’s a sign that there is something wrong. This should be especially concerning if the system could previously provide that level of output, but cannot anymore.

Repair Increases

A healthy system doesn’t need repairs more than once or twice every few years. In an older system, though, the wear and tear built up from years of use makes it more likely for multiple parts to fail at once. If you have to get your water heater repaired every few months, that’s a sign that you need to replace the whole system.
