Brivis Buffalo Spare Parts: Platform Compatibility and Parts Guide
Written by Rica Francia Macaspac, HVAC Shop June 2026 · Last reviewed: June 2026.
If a ducted gas heater badged as Buffalo needs a spare part and the search results keep returning Brivis products, that is not a mistake. Buffalo units run on the same engineering platform as Brivis, which means a significant proportion of components are shared or directly compatible. This guide explains the relationship between the two brands, which parts cross over reliably, and how to confirm compatibility for your specific unit before ordering. All compatible parts are available through our Brivis Buffalo compatible spare parts collection.
What Is Brivis Buffalo
Buffalo is a ducted gas heater brand built on the same engineering platform developed by Brivis Climate Systems. The same combustion architecture, control circuit design, and safety system that underpin Brivis, Braemar, and Bonaire heaters also underpin Buffalo units. The brand name on the cabinet is different, but the internal engineering and a large proportion of the components are shared across the platform.
This matters directly for spare parts sourcing. Buffalo-badged units are typically sold under their own brand name through different retail channels than Brivis, which can make some homeowners and technicians assume they need brand-specific Buffalo parts that are harder to source. In practice, the majority of replacement components for a Buffalo ducted gas heater are listed and stocked under the Brivis platform parts range, using the same BS part codes that apply across Brivis, Braemar, and Bonaire.
As with any cross-brand platform component, the BS part code on the original component is the definitive compatibility check. Brand name alone is a reasonable starting point, but it should never be the only confirmation before ordering a replacement part.
Which Brivis Parts Fit Buffalo Units
The component categories below are the most reliable platform crossovers between Brivis and Buffalo. Always confirm by BS part code before ordering, but these are the categories where compatibility is most consistently confirmed.
Control Boards
The N-E6 control board is the standard PCB across the Brivis platform and fits units badged as Brivis, Braemar, Bonaire, and Buffalo. The board itself is identical regardless of brand name on the cabinet, with the same BS codes applying to the same hardware. The N-E6 control board compatible with Buffalo is the with-switch variant (BS81008783). The no-switch variant (BS81065300) is the other common fitment, and the two are not interchangeable. Confirm which variant is fitted in the Buffalo unit by checking the face of the original board for the presence or absence of an integrated switch before ordering.
Ignition Parts
The pilot and ignition assembly used across the Brivis platform applies to Buffalo units as well. The HCCA621 pilot lead assembly (BS80021192) is the standard replacement for pilot and ignition faults on Buffalo heaters, identical to the part used on Brivis, Braemar, and Bonaire units. Gas type still requires confirmation regardless of platform crossover: confirm whether the Buffalo unit runs on natural gas (NG) or LPG from the data plate before ordering, as the pilot assembly is gas-type specific. Installation of any pilot or ignition component requires a licenced gas fitter in accordance with AS/NZS 5601.
Gas Valves
The White Rodgers 24V solenoid gas valve is the standard valve platform across Brivis, Braemar, Bonaire, and Buffalo ducted gas heaters. The 24V gas control valve (W0085, Buffalo compatible) suits the most common applications on Buffalo units in the same way it does across the rest of the platform. As with the pilot assembly, gas type confirmation from the data plate is required before ordering, since this component is available in both NG and LPG variants. Gas valve installation requires a licenced gas fitter.
Pressure Switches
Pressure switches in the same Pascal (Pa) ratings used across Brivis, Braemar, and Bonaire also apply to Buffalo units. The same range of 50, 80, 115, 140, and 165Pa switches covers the platform regardless of brand badge. As always, the Pa rating must match the original switch exactly: read it from the label on the original component before ordering, and do not substitute a different rating even if a switch with a different Pa rating appears physically identical.
Tradie Pro Tip: Buffalo units are less commonly seen on service runs than Brivis-badged heaters in most areas, which means technicians sometimes hesitate before ordering platform parts for them. Treat a Buffalo unit exactly as you would a Brivis, Braemar, or Bonaire unit: read the BS code from the failed component and order against that code. The platform parts range covers Buffalo reliably in the majority of cases.
Cross-Brand Overlap: Braemar and Bonaire
Buffalo also shares platform components with Braemar and Bonaire in many cases, since all four brands sit on the same underlying Brivis engineering platform. This is useful in practice: a technician already carrying common platform parts for Brivis, Braemar, or Bonaire service work is very likely also carrying the correct parts for a Buffalo call-out, without needing a separate stock line specifically for Buffalo.
As with any cross-brand compatibility claim, always verify by BS part code first before assuming a part will fit based on brand name alone. Heat exchangers, wiring looms, and some generation-specific components can differ between brands even on units that otherwise share the majority of their platform components. The BS code on the original component remains the definitive check regardless of how many brands a given part is known to fit.
For technicians who also service Braemar units regularly, the Braemar spare parts collection lists the same platform components with Braemar-specific model cross-references, which can be a useful secondary reference point when confirming Buffalo compatibility against a known Braemar fitment.
| Component | Buffalo Compatible | Key Selection Check |
|---|---|---|
| N-E6 Control Board | Yes | Confirm with or without switch variant |
| HCCA621 Pilot Lead Assembly | Yes | Confirm gas type (NG or LPG) |
| White Rodgers 24V Gas Valve | Yes | Confirm gas type (NG or LPG) |
| Pressure Switches (all Pa ratings) | Yes | Pa rating must match exactly |
| Heat Exchanger | Verify by BS code | Not reliably interchangeable across all models |
| Wiring Loom | Verify by BS code | Connector types can differ by generation |
Identifying a Buffalo Unit on Site
For technicians arriving on a service call where the brand has not been confirmed in advance, recognising a Buffalo unit on sight is straightforward once you know what to look for. The cabinet badge and any printed branding on the front panel will typically display the Buffalo name, distinct from the Brivis, Braemar, or Bonaire branding used on the equivalent platform units. Beyond the badge, the cabinet shape, access panel layout, and internal component placement closely mirror other platform brands, since they share the same underlying chassis design in most model generations.
The data plate remains the most reliable source of information regardless of brand recognition. Locate it inside the front access panel or on the unit body, and confirm the model number, gas type, and input rating before beginning any diagnostic work. Some Buffalo data plates list a model number format that closely resembles the equivalent Brivis model naming convention, which is a further indicator of the shared platform origin, though this should not be relied upon as a substitute for checking BS codes on individual components.
If a homeowner is uncertain whether their unit is a Buffalo, a Brivis, or another platform brand, and the badge is worn, missing, or obscured by age, the safest approach is the same regardless of brand: locate the data plate, photograph it, and read the BS code from the failed component. The repair process and parts sourcing approach do not change based on which platform brand badge happens to be on the cabinet.
Tradie Pro Tip: If you are quoting a job over the phone before seeing the unit and the homeowner mentions a Buffalo heater, do not assume parts will need to be specially sourced or take longer to arrive. Treat the quote exactly as you would for a Brivis job of the same age and fault type. The platform parts range covers Buffalo reliably, and setting accurate expectations upfront avoids an awkward conversation later if the homeowner was told to expect a longer wait that never eventuates.
How to Order Buffalo Parts
Ordering parts for a Buffalo unit follows the same process as ordering for any platform brand. First, match the BS code from the data plate and the failed component. The data plate on a Buffalo unit is located in the same position conventions used across the Brivis platform: typically inside the front access panel or on the unit body. It lists the model number, serial number, gas type, and input rating.
Second, confirm the gas type from the data plate before ordering any gas-contact component. As with every other brand on this platform, Buffalo units are configured for either natural gas (NG) or LPG, and gas-specific components including gas valves, pilot assemblies, and burners are not interchangeable between gas types. Installing the wrong gas type component is a safety hazard and a breach of AS/NZS 5601 regardless of which brand badge is on the unit.
Third, read the BS code from the original component and search for the matching replacement in the Brivis platform parts range. If the BS code matches, the part fits the Buffalo unit. If the original component label is damaged or unreadable, the model number from the data plate is the fallback reference, and contacting us with both the model number and a description of the fault will allow us to confirm the correct part before you order.
Did You Know? Buffalo heaters are common in older housing stock in some regional Australian areas, including parts of country Victoria and inland New South Wales, where they were a popular installation choice in past decades. Many of these units are now reaching an age where ignition components, pressure switches, and control boards are due for replacement, and the good news is that platform compatibility means parts availability is no different to servicing a Brivis unit of the same age.
All gas component installation on Buffalo units, exactly as with Brivis, Braemar, and Bonaire, must be carried out by a licenced gas fitter in accordance with AS/NZS 5601. Electrical components such as control boards and transformers should be replaced by a qualified electrician or HVAC technician. For state-by-state gas installation licencing requirements, refer to Safe Work Australia.
