Dallas Area Tankless water heater flushing service

How often does my tankless water heater need to be flushed?

Most manufacturers recommend flushing your tankless water heater annually. In North Texas, where the water is particularly hard due to its high mineral content, regular flushing becomes even more critical. Our technician will use a pump and special solution to perform a thorough internal cleaning of your tankless unit, restoring it to peak performance.

Why does my tankless water heater need to be flushed?

When you boil a pot of water until it fully evaporates, a white, powdery residue remains, composed of the minerals present in the water. Similarly, as cold water flows into your tankless water heater, it is rapidly heated through a heat exchange process. This quick heating, much like the boiling pot, causes mineral buildup inside the unit.
