Tips for Maintaining Your Tankless Water Heater ^Featured

Tankless, or on-demand water heaters are high tech appliances that deliver an endless supply of hot water throughout the home. They can save a lot of energy by heating water only when it’s needed, unlike a tank water heater that must heat the tank continuously. Tankless water heaters are also one of the most complex plumbing devices available for the home and require proper maintenance to ensure they operate efficiently and reliably.

Removing Limescale

Over time, tankless water heaters will accumulate minerals on the inside of the tank’s heating chamber. This buildup can reduce efficiency and cause the unit to run louder than usual when heating. The unit should be flushed regularly, usually once a year, to remove to accumulated mineral deposits. The steps involved will vary by manufacturer, but the procedure usually involves attaching a hose and flushing the tank with vinegar. If you’re not sure of the procedure you should have a qualified technician maintain the unit.

Cleaning the Screen Filter

The second tankless water heater maintenance task involves cleaning the in-line screen filter to remove any accumulated debris.  First, 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. Because the procedure will vary by manufacturer, it’s a good idea to have a qualified technician perform the maintenance.
