Brivis ducted gas heaters are built to last, but when a component fails after years of service, the right replacement part gets the system back on quickly without replacing the whole unit. This guide covers every key replacement part in the Brivis gas ducted heater range: gas valves, burner zip tubes, pressure switches, thermocouples, control boards, and transformers. Includes a full component reference table, cross-brand compatibility guidance for Braemar and Bonaire, and selection criteria for every part type.

Brivis, Braemar, and Bonaire ducted gas heaters share a common engineering platform, which means a significant number of spare parts are interchangeable across all three brands. This guide covers exactly which components cross over, including the N-E6 control board, White Rodgers 24V gas valve, and pressure switches across all Pa ratings, what differs between brands such as heat exchangers and wiring looms, and the only reliable method for confirming compatibility before you order: matching by BS part code.

Buffalo ducted gas heaters run on the same engineering platform as Brivis, meaning a significant proportion of spare parts are directly compatible. This guide explains the relationship between the two brands, which parts cross over reliably (control boards, ignition assemblies, gas valves, pressure switches), and how to confirm compatibility for your specific Buffalo unit before ordering.
