How to Maintain a Tankless Water Heater

Tankless water heaters provide you with an energy-efficient water supply that delivers hot water on demand. They have quickly risen to popularity because of their small size and increased efficiency, making them suitable for residential and business properties.


While they often make a better option than traditional water heaters, you’ll need to maintain your tank to avoid problems and ensure the longevity of your investment. Regular maintenance can help your water heater serve you best and last for decades.


Maintaining your tankless water heater doesn’t mean that you have to get it serviced every month. Still, you should have your tankless heater expected annually alongside your recommended maintenance plan. If you live in an area where hard water supplies exist, it is advised to get your tankless hot water serviced twice a year, and this ensures that all the components in the heater work as they should.


In addition to regular servicing, some steps need to be taken to maintain your system. Let’s explore!


3 Maintenance Tips for Tankless Water Heaters


If you have a tankless water heater, take the following steps each year to ensure you get the most extended lifespan out of your investment.


1.   Flush the System


The first and the most crucial step to maintaining your tankless water heater is to get it flushed at least once per year. This is important because minerals collect inside your water heater throughout the year and can damage your system. If you have a hard water supply, these minerals will build up faster. Flushing them away every year can help protect your tank.


Failing to flush the system each year is a problem that many homeowners face. As mineral build-up gets worse, it can damage the heat exchanger in your unit, decreasing the efficiency of your unit and causing your tank to fail. You can even end up with higher than regular electric bills and risk reducing the life expectancy of your system.

Make sure to get your water heater flushed annually before it’s too late. Failing to do so can require a total system replacement. You can also do it at home by washing a mixture of vinegar water through the water heater. Check your water heater’s manual for instructions on how to do this for your specific tank, or you can purchase a descaling kit that will have all the instructions.


2.   Clean the Air Filter


There is an air filter in your tankless water heater that you will need to clean regularly. You can easily clean it by removing it from the water heater and cleaning it with a soft brush dipped in a soap and water solution. You should clean it thoroughly for proper airflow at the end of each season, rinse it well, and then let it completely dry before you put it back in the water heater.


3.   Clean the Water Filter


Another critical step to keep your water heater maintained is to keep the water filter clean. Most tankless water heaters have a screen that traps any sediments coming in. These sediments will need to be cleaned out from time to time to ensure the proper functioning of your water heater. All you need to do is cut off the water supply, gently remove the filter and wash all sediment away. You can do this simply with warm soapy water or hire a professional to handle the job.
