Simple Steps in Maintaining Tankless Water Heaters

Tankless water heaters are energy-efficient alternatives for your water heating needs. These can provide hot water to your family for at least two decades, but proper maintenance and annual checks can even prolong their life expectancy and continue contributing to lower energy costs.

Have basic knowledge of your water heater. Where is it located, and how is it turned off? Knowing these basic information about your tankless water heater should be your first step in maintaining them.

Turn off your tankless water heater. After turning off the power source, remove the lid from your water heater and close off the three water valves. Once all valves have been removed, use 2.5 gallons of undiluted white vinegar to clean your water heater.

Flush and drain. Follow the instructions provided by the manufacturer in flushing and draining your tankless water heater. Once the flushing process is complete, close the purge port valves, disconnect the hosing lines from each water valve, and replace the purge port valve caps onto the purge valves.

Clean the filter. Find the label indicating the filter’s location, remove it from the water heater, and clean it under running water. Replace it as indicated on the manual.

Have them inspected annually. You may be unknowingly ignoring a more serious problem on your water heater. Avoid this by having them checked annually by professionals.
