The Baxi 5114692 Expansion Vessel (10-litre) plays a critical role in maintaining the safe operation of a sealed central heating system. As water heats up, it expands—this vessel absorbs the extra volume, preventing dangerous pressure increases that could damage the boiler, radiators, or pipework. It’s constructed with a durable diaphragm that separates air from water, ensuring reliable pressure regulation over time. Engineered to meet Baxi’s strict performance standards, this OEM replacement part is compatible with a range of Baxi boiler models. Ideal for repairs, upgrades, or servicing, the 5114692 vessel ensures the system runs smoothly and efficiently, while reducing the risk of leaks and pressure-related faults.
