If you are looking for spare parts for a Braemar or Bonaire ducted gas heater and finding Brivis parts in the search results, you are not looking in the wrong place. These three brands share a common engineering platform, and a significant number of components are identical across all three product families. Understanding which parts cross over and how to confirm compatibility before ordering is what this guide covers. It is a practical, direct answer to the question tradies and homeowners ask constantly: will this Brivis part fit my Braemar, or my Bonaire? Often the answer is yes, but the method for confirming it is the same every time.

The Brivis Platform Explained

Brivis, Braemar, and Bonaire are three separate brands built on the same ducted gas heating platform developed by Brivis Climate Systems. The platform engineering is shared: the combustion system, the control architecture, and the key safety circuit components were developed as a common base across all three product families. This is why so many spare parts are interchangeable. It is not a coincidence or an approximation. Many service parts are shared across the platform, but compatibility still needs to be confirmed by the BS part number on the original component.

For spare parts purposes, this matters because it expands the pool of compatible components and means a part listed under one brand will often suit a unit badged under another. The Brivis spare parts collection includes platform components that suit Brivis, Braemar, Bonaire, and Buffalo units. Buffalo is a fourth brand on the same platform, covered in more detail in the dedicated Buffalo compatibility guide.

The practical implication for anyone servicing or repairing these heaters is that brand name alone does not determine compatibility. Two units badged as different brands may take identical components. Equally, two units badged as the same brand may require different parts if they are from different production generations. The BS part code on the original component is always the definitive compatibility check.

Which Parts Cross Over Between Brands

The following component categories are common platform crossovers across Brivis, Braemar, and Bonaire. Always verify by BS part number before ordering, but these are the categories where cross-brand compatibility is most commonly seen.

Control Boards

The N-E6 control board is the most widely used PCB across the Brivis platform and fits units badged as Brivis, Braemar, Bonaire, and Buffalo. It is the same board, with the same BS codes, regardless of which brand name is on the heater cabinet. The N-E6 control board (fits Brivis and Braemar) (BS81008783) is the with-switch variant. The no-switch variant (BS81065300) is the other common fitment. Confirm which variant is installed in the specific unit before ordering: check the face of the original board for the presence or absence of an integrated switch. The two variants are not interchangeable regardless of which brand the unit carries.

Gas Valves

The White Rodgers 24V solenoid gas valve is the standard gas valve platform across Brivis, Braemar, Bonaire, and Buffalo ducted gas heaters. The White Rodgers 24V gas valve (W0085) suits the most common applications across all four brands. Gas type is still a required confirmation even on a confirmed platform crossover. A valve listed as compatible with both Brivis and Braemar units is available in natural gas (NG) and LPG variants, and the gas type must match the unit being serviced. Confirm from the data plate before ordering. Gas valve installation requires a licensed gas fitter in accordance with AS/NZS 5601.

Pressure Switches

Pressure switches in the same Pa ratings are used across the Brivis platform brands. A Braemar unit fitted with an 80Pa pressure switch uses the same component as a Brivis unit fitted with an 80Pa switch. The Brivis Braemar pressure switch 80Pa (BS80021373) is stocked as a platform component that suits both brands. The same principle applies across all Pa ratings in the range: 50, 80, 115, 140, and 165Pa. The Pa rating must match the original switch exactly regardless of which brand the unit carries. Read the Pa rating from the label on the original switch before ordering.

For Brivis and Braemar pressure switches, the Pa rating and bracket length must both match the original exactly. Do not order by appearance alone, as switches with the same shape can have different pressure ratings, bracket lengths, or mounting positions.

Tradie Pro Tip: On service calls where the unit brand badge has been removed or is unreadable, the BS code on the components inside the unit tells you everything you need to know. A BS-coded pressure switch or control board is a Brivis platform component regardless of what the cabinet says on the outside. Work from the BS codes and you will always order the right part.

What Is Different Between Brands

Cross-brand compatibility across control boards, gas valves, and pressure switches is well established, but not every component crosses over. Some components are brand-specific or generation-specific, and ordering the wrong one because of an assumed compatibility can cause problems that take time to diagnose.

Heat exchangers are among the components most likely to differ between brands. Although the combustion platform is shared, the physical form factor of the heat exchanger can vary between Brivis, Braemar, and Bonaire units depending on the model series and production year. A heat exchanger ordered by brand name alone rather than by BS code has a meaningful chance of being incorrect.

Wiring looms can also differ between brands, particularly across production generations. Even where the control board is the same, the loom connecting it to other system components may have different connector types, lengths, or routing depending on the model. Always check the BS code on the loom you are replacing rather than assuming a Brivis loom will match a Braemar unit of similar age.

Combustion fan assemblies and some cabinet components are also areas where brand-specific differences can appear. The general rule is that the deeper you go into the physical structure of the unit, the more likely you are to encounter brand-specific or model-specific components. The control circuit components, gas valve, and pressure switches are the most reliably cross-compatible. Structural and heat transfer components are more variable.

How to Verify Compatibility Before Ordering

The compatibility table above gives you a solid starting point, but there is only one method that confirms compatibility with certainty for any specific unit: matching the BS part code. The BS code on the original component is the manufacturer's definitive identifier. If the BS code on the replacement part matches the BS code on the component you are replacing, the part fits. If they do not match, the part does not fit regardless of what the product description says.

The workflow for any cross-brand parts order should follow this sequence. First, locate the data plate on the unit and confirm the model number and gas type. Second, read the BS code from the component you are replacing. Third, search for the replacement part by BS code. Fourth, confirm gas type if the component is gas-contact. Fifth, confirm any variant-specific detail such as Pa rating for pressure switches, amperage for transformers, or with/without switch for control boards.

For pressure switches specifically, the Pa rating is the critical specification that overrides any general compatibility assumption. Two units, one Brivis and one Braemar, may both use 80Pa switches and the same switch fits both. But a Brivis unit fitted with a 115Pa switch and a Braemar unit fitted with an 80Pa switch require different components even though they are on the same platform. The Pa rating is set by the combustion fan and heat exchanger specification of each individual model, not by brand. Read it from the original switch label every time.

Did You Know? The same cross-brand platform logic applies to Brivis evaporative cooler components in some cases. The NC-6 Networker controller, for example, integrates with both Brivis gas heaters and Brivis evaporative coolers in a combined heating and cooling network. If you are working on a combined system, check whether the component spans both the heating and cooling sides before ordering.

Ordering Cross-Brand Parts: What to Have Ready

When ordering a part for a Braemar or Bonaire unit from a Brivis parts listing, the same information applies as for any Brivis order. Have the BS code from the original component, the model number from the data plate, the gas type confirmed from the data plate, and any variant-specific detail for the component type you are ordering.

If the original component label is damaged or missing and you are working from the model number alone, contact us before ordering. Cross-brand model number cross-referencing requires specific knowledge of production runs and component fitment history, and an experienced parts supplier can confirm the correct BS code for your unit before you place the order. This is worth doing rather than ordering on a best guess and waiting for a return if the part is wrong.

For Braemar-specific parts and cross-reference listings, browse the Braemar spare parts collection alongside the Brivis listings. Platform components appear in both collections with brand-relevant model cross-references where they are available. For a complete reference on all replacement part categories across the Brivis gas heater platform, the Brivis gas heater replacement parts guide covers every component type in detail.

All gas component installation across Brivis, Braemar, and Bonaire units must be carried out by a licensed gas fitter in accordance with AS/NZS 5601. Electrical components require a licensed electrician or qualified HVAC technician. For current state licencing requirements, refer to Safe Work Australia.

Tradie Pro Tip: If you regularly service across all three brands in an area like Melbourne's outer suburbs or regional South Australia where Braemar, Brivis, and Bonaire units are all common, stocking the N-E6 board in both variants and the White Rodgers gas valve covers the majority of control and gas valve replacements across your entire run. These platform parts have good shelf life and a known failure pattern that makes them worth having on the van.
