Tankless, or on-demand water heaters, are high tech appliances that deliver an virtually endless supply of hot water, while saving energy by heating water only when it's needed. They are also one of the most complex plumbing devices found in the home and require regular maintenance to ensure efficient operation and long term reliability.
Removing LimescaleOver 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 one 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 FilterThe 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.
