How To Flush Your Tankless Water Heater

Every year your tankless water heater should go through a descaling process.  The purpose of this is to remove calcium build up in your heat exchanger so that your high efficient appliance can run smoothly without having to work harder than it already does.  Leaving the calcium build up on and not descaling the water heater will cause the unit to over fire by trying to heat a liquid (water) bu instead heating an extra insulated layer of calcium build up on your pipe walls within the heat exchanger.
