Baxi 10L Expansion Vessel - 5114692 - Fits Duo-tec / Platinum (33-40 kW) & Selected System Models (see list) 10-litre internal expansion vessel for selected Baxi boilers where a larger vessel is specified (often 33-40 kW outputs). Part ref: 5114692. Typical use case: Duo-tec & Platinum Combi 33/40 kW and matched System variants that require a 10 L vessel (check your boiler’s parts list). Pre-charge & sizing (per manuals): vessel usually supplied ~0.5 bar; larger system volumes may still need an additional external vessel; PRV typically 3 bar. (Set exactly as per the appliance manual.) Helps prevent nuisance pressure spikes/PRV discharge in sealed CH systems; replace like-for-like where 10 L is specified.
