Genuine Baxi 5114691 Expansion Vessel 8L – Original Plain Boxed Part

Maintain consistent and safe pressure within your heating system with the Genuine Baxi 5114691 8-Litre Expansion Vessel. As water in your central heating system heats up and expands, this vital heavy-duty component absorbs the excess volume, preventing dangerous pressure spikes and protecting your boiler's internal parts and pipework from unnecessary stress or failure.

If your boiler is constantly losing pressure, requiring frequent manual top-ups, or discharging water from the pressure relief valve, a ruptured or depressurized expansion vessel is often the culprit. Replacing it with this brand new, authentic manufacturer spare ensures exact system compatibility and reliable, long-lasting performance.

Supplied exactly as pictured in plain protective packaging, this original 8L Baxi vessel is the trusted choice for a professional and secure repair from Warwick Heating Supplies.
