How to Maintain Your Tankless Water Heater – Annual Descale Flush

💧 TANKLESS WATER HEATER MAINTENANCE – A tankless water heater is NOT a set-it and forget-it type appliance. Based on water quality and other operating functions, you’ll want to flush the water heater heat exchanger at least every 18 months or so and more often if your water has a high mineral content..

  • IMPORTANT – It’s best to search and download the owner’s manual for ALL appliances in your home – especially the tankless water heater owner’s manual.
  • Here’s a VIDEO that can help point you in the right direction (or scroll down to watch the video). Most models use the same flushing system valves. This video was created by Noritz.
  • Here’s a STEP-BY-STEP procedure to follow if you want to tackle the task on your own.
