If you own a tankless water heater, you should schedule an annual service call, which includes a tankless water heater flush and checkup. The flushing process is important but tedious, which is why you need a professional plumber to do it. Without an annual flush, you could void your water heater’s warranty and increase the chances of problems. Understanding more about this process and how it works will help you see how critical it is to your water heater’s operation and lifespan.

What Is a Tankless Water Heater Flush?

Most homes across the country have hard water coming into their plumbing systems. Hard water contains dissolved minerals that you don’t taste when drinking it. When heated, the minerals separate from the water and sink down. Inside water heaters, these minerals can result in sediment or buildup inside the unit, which may reduce the heater’s ability to provide enough heat to get water passing through it to the desired temperature.

How a Tankless Water Heater Flush Works

A tankless water heater flush works by washing out the minerals inside the unit with fresh, unheated water. Annual flushing ensures the water heater doesn’t experience mineral buildup that a flush cannot remove. If you have exceptionally high mineral content in your water, you may need to request a tankless water heater flush more than once a year. Talk to your plumber for recommendations. However, installing a whole-home water softener can counter the effects of extra-hard water and reduce your needed flushes to once a year.

Why You Need an Annual Flush for Your Tankless Water Heater

Top water heater manufacturers, such as Rinnai and Rheem, recommend annual flushing of their tankless models. Doing so removes mineral deposits that can accumulate inside the unit and reduce the ability of the unit to heat water on-demand.

While Rinnai offers step-by-step instructions for the process, few homeowners will have the patience, tools, time, or expertise with plumbing to go through all 13 steps correctly. Plumbers can do these steps quickly and correctly, to get this chore completed properly.
