Tankless Water Heater Flushing Service​

Regular maintenance can help reduce the risk of buildup-related performance issues and support the ongoing care of your unit.

Why flushing matters

Restore Efficiency

Reducing mineral buildup can help the unit transfer heat and operate as designed.

Limit Buildup

Routine care can help limit buildup that places extra strain on internal components.

Ensure Reliable Hot Water

When mineral buildup is contributing to temperature or flow issues, flushing can assist in providing a consistent supply of hot water.

Save on Energy Bills

A cleaner heat exchanger may allow the unit to operate more efficiently leading to potential significant energy savings.

Routine Maintenance for a Hardworking System

Every time your tankless water heater runs, water passes through narrow internal channels where it is heated on demand. Minerals naturally present in the water can settle inside those passages. The amount and speed of buildup vary by water quality, household use, equipment and maintenance history.

A routine flush circulates a cleaning solution through the unit to help loosen and remove mineral deposits. Keeping buildup under control can support water flow, heat transfer and the long-term care of the system.
