When to Replace Your Tankless Water Heater

Tankless water heaters are becoming more and more popular among homeowners who are looking to save money and space in their homes. Though they are a great alternative to the traditional storage tank water heater variety, they still aren’t invincible. Regardless of how well you take care of your tankless water heater, you will have to replace it at some point. When that time comes, it’s beneficial to recognize the signs before the water heater fails completely. Let’s examine some of the more common signs that your tankless water heater needs replacing.


Tankless water heaters are made to last anywhere from 10 to 15 years. Once they get older than that, it becomes more and more likely that they will develop problems that seriously hinder their operation. You can keep your system running past this point, but it will become more and more expensive to keep it in operating condition. Once your tankless water heater gets older than 15, you should replace it.


Every system needs repairs every now and again, but typical systems don’t need them more than once every couple of years. In an older tankless water heater, the wear and tear on the parts that make up the system will eventually cause them to fail. This cascade failure increases the amount of repairs necessary to keep the system running. If you need to repair your tankless water heater every few months, it’s time to replace it.


If you place a high enough demand on your tankless system, you will overwhelm it and it won’t be able to produce hot water fast enough. If your tankless water heater can’t really keep up with even moderate demand for hot water, though, it might mean that it is worn out and needs replacing.
