If you have hard water and use a tankless water heater, sooner or later you WILL need to flush your unit. If you follow this simple routine annually you will get the full 20+ year life from your unit. Otherwise, it's an early death for sure. Feel free to ignore this if you have a water softener or otherwise have soft water at your house.

Supply list:

  • 5 gallon bucket $5)
  • 2 gallons of White Vinegar ($10)
  • Submersible Ulitity Pump 1/6 to 1/3HP ($50-90 Here's a link to the one I use from Amazon)
  • Set of Washer Hoses. ($10-15 Amazon link but you can buy these anywhere.)

Total time for this process should be about 90 minutes and it will save you a ton of hassle and money from getting a clogged system from boiler scale.

Hope this helps!
