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.

Ordering the wrong Brivis spare part almost always comes down to one thing — not having the correct part number before placing the order. This step-by-step guide shows you exactly how to find the data plate on your Brivis heater, read BS part codes, confirm gas type (NG vs LPG), identify the correct pressure switch Pa rating, match transformer amperage, and tell the difference between N-E6 control board variants. Get it right the first time.

When a Brivis ducted gas heater stops working, the fault usually comes down to one specific component. This complete guide covers every major spare part in the Brivis range — ignition assemblies, pressure switches, control boards, thermocouples, gas valves, and transformers — including how to identify the correct part by BS code, why gas type and Pa rating matter, and what to check before you order. Covers Brivis, Braemar, Bonaire, and Buffalo platform compatibility.
