About Baxi Parts

Baxi traces its roots back to 1866, when Richard Baxendale founded an iron foundry in Preston, and it has grown into one of Europe's best-known manufacturers of domestic and commercial heating systems. Since 2010, Baxi has been part of the BDR Thermea Group, formed by Baxi's merger with De Dietrich Remeha, which is why Broag Remeha parts are stocked alongside Baxi domestic and Baxi Commercial spares in this range. Because gas boilers rely on precise sealing, sensing and combustion components to run safely and efficiently, worn gaskets, O-rings and sensors are among the most common causes of faults, and need replacing with the correct part for your exact model.

Looking for parts from other BDR Thermea brands? Browse our Heatrae Sadia Parts and Broag Remeha Parts ranges, or all HVAC and heating parts.

Common Baxi Parts We Stock

  • Gaskets & seals — burner gaskets, combustion chamber gaskets, heat exchanger gaskets, fan gaskets and combustion box door seals that keep the sealed combustion circuit airtight
  • O-rings & washers — a wide range of O-rings, sealing washers and outer adapter washer seals used throughout the boiler's water and gas circuits
  • Thermostats & sensors — limit thermostats and NTC sensors, with fitting screws and gaskets included where applicable
  • Controls — control knobs for setting temperature and operating mode
  • Flue & condensate components — outlet bends and condensate siphon plug assemblies for the boiler's exhaust and drainage system
  • Adapters & fittings — tap adapters and joint assemblies for pipework connections into and out of the appliance
  • Insulation — front panel insulation to maintain the boiler's noise and heat containment

This range covers three sub-categories you can browse separately: Baxi Parts (domestic boilers), Baxi Commercial Parts and Broag Remeha Parts, so start with the right one for your appliance to narrow things down quickly.

How to Find the Right Baxi Part

Baxi and Remeha parts are matched to the exact boiler model, so start by checking the model and serial number on your boiler's data plate, then cross-check the manufacturer's part number on the component you're replacing. We stock both genuine and compatible options across the range, so you can choose on price and preference. If you're not sure which part you need, use our Can't Identify Your Spare Part? service, or send our trade counter team the model number or a photo of the old component and we'll match it for you.

Baxi Parts — Frequently Asked Questions

How do I know which Baxi part I need?

Check your boiler's data plate for the exact model and serial number, then match the manufacturer's part number on the component you're replacing. If you're unsure, send us the details and we'll confirm the correct part.

What's the difference between Baxi Parts, Baxi Commercial Parts and Broag Remeha Parts?

Baxi Parts covers domestic boiler spares, Baxi Commercial Parts covers larger commercial appliances, and Broag Remeha Parts covers equipment from Remeha, a sister brand under the same BDR Thermea group. Use the sub-category filters to narrow down to your appliance type.

Are these genuine or compatible Baxi parts?

We stock a mix of both — genuine Baxi components alongside compatible alternatives on selected items, so you can filter by part origin and choose based on price and preference.

What causes O-ring and gasket failures on a Baxi boiler?

O-rings and gaskets harden and perish with age and heat cycling, which is a common cause of weeping joints, leaks or reduced efficiency during a service. Replacing them with the correct genuine part is usually straightforward preventative maintenance.

Should I replace boiler seals and sensors myself?

Gas boiler servicing and repair should be carried out by a Gas Safe registered engineer, as these components sit within the sealed combustion circuit and affect the safe operation of the appliance.
