The Magnetic System Filter on Your Navien Boiler

A magnetic system filter traps the black iron-oxide sludge and debris that circulates in heating systems, protecting the heat exchanger, pump and valves. Fitting one is one of the best ways to extend boiler life in older Greater Vancouver systems.

On Navien systems — including models such as NCB-240E, NCB-210E, NHB-150 — a failing magnetic system filter often shows up as e003 ignition failure or related symptoms. We diagnose it precisely and install the correct genuine Navien part.
