Why Is It Important to Flush Your Tankless Water Heater?
Tankless water heaters provide hot water on demand, but “tankless” does not mean maintenance-free. Over time, minerals naturally found in your water can build up inside the heat exchanger and water pathways. Routine flushing helps loosen and remove this mineral scale, supporting efficient operation and the long-term care of your system. Learn why annual flushing is recommended, how water quality affects buildup, and when your tankless water heater may need professional attention.
