Conducting Maintenance On A Tankless Water Heater

Liberty Plumbing • August 23, 2022

Tankless water heaters have become a popular alternative to traditional units because they don’t need as much attention or as many replacement parts. Less maintenance is always a plus, but it’s important for homeowners to understand that “less” doesn’t mean “zero.” Following these three simple tasks to maintain your tankless water heater in between your yearly tune-ups. Conducting tankless system maintenance can keep your tankless water heater in great shape for years to come.

Three Important Maintenance Steps

Maximizing the life and overall performance of your tankless water heater really is quite simple.

Clean Or Replace The Water Line Filter

Most tankless water heaters have a water line filter that protects your unit, as well as your faucets, pipes, and appliances, against contaminants such as sediment, scale, and hard water. Depending on the type of tankless water heater you have, you will need to either replace or clean and reuse your filter to prevent these impurities from flowing and building up in your plumbing system.

Clean The Air Filter

If your tankless water heater has a filter between the air intake pipe and the fan, you will want to regularly check to make sure the filter is not clogged with dirt, bugs, and other debris that can slow, or even stop, airflow. It is very important to make sure that you allow your air filter to completely dry before reinserting it into your unit.

Descaling and Flushing The System

If you have hard water, it is recommended that you descale and flush your tankless water heater at least once a year. If you have soft water or a water softener system installed in your home, this can be done every 3 to 5 years.

To descale your tankless water heater, you will need a submersible pump to cycle either white vinegar or descaling solution through your unit for at least 45 minutes. After you remove the scale from your system, you will want to flush the unit with clean water by attaching your garden hose to the hot side service valve.
