Navien 30013685A - DHW Flow Sensor

The Navien 30013685A is a domestic hot water (DHW) flow sensor designed for use in Navien tankless water heaters, especially those in the CH series. This sensor plays a critical role in energy-efficient operation by detecting water flow and signaling the control board to activate or deactivate the heating element accordingly.

By ensuring that the heater only operates when water is actually flowing, the sensor helps reduce energy consumption, extend system lifespan, and maintain responsive hot water delivery. Built from durable materials and designed for easy replacement, it is a reliable component for maintaining peak system performance.
