The overview

What it is, and why it matters.

Middle Tennessee water often carries dissolved minerals, and heating it leaves scale on the inside of a tankless unit. Scale insulates the heat exchanger, restricts flow and triggers error codes, so the heater works harder and wears out faster.

We connect a pump and a descaling solution to the service valves, circulate it through the heat exchanger, flush, clean the inlet filter and check combustion and venting. For homes in the Nashville area with hard water, a softener can keep scale from coming back.

Good questions

Tankless Flush and Descaling: common questions

How often should a tankless water heater be flushed?

Once a year is a common recommendation, and more often in hard water. Check your manual, because warranty terms often depend on it.

My unit has no service valves. Can you add them?

Yes. Adding isolation and service valves is a small job that makes every future flush faster and cheaper.
