The Importance of Tankless Water Heater Maintenance

Tankless water heaters are high tech devices that deliver an endless supply of hot water. By heating water only when it's needed, it can save significant energy compared to conventional tank-style water heaters. Because of their complexity, tankless water heaters require regular maintenance to ensure proper operation and long-term reliability. While the maintenance procedure will vary by manufacturer, here are two of the most common maintenance tasks.

Removing Limescale

Over time, tankless water heaters will accumulate minerals on the inside of the tank's heating chamber. To remove the mineral build up the unit should be flushed regularly, usually once a year, to remove these accumulated mineral deposits. The steps involved will vary by manufacturer, but the procedure usually involves attaching a hose and flushing the tank with vinegar.

Cleaning the Screen Filter

The second tankless water heater maintenance task involves cleaning the in-line screen filter to remove any accumulated debris. Turn off the incoming water supply. The filter is located on inlet fixture on the cabinet. Unscrew the plug to remove the filter. Rinse the filter off and reinstall it on the unit.
