What it is
The Baxi expansion vessel hose assembly (part number 7810662) connects the expansion vessel to the heating circuit on Baxi Combi 2 appliances. It carries system water between the vessel and the boiler's hydraulic components, allowing the vessel to absorb expansion as the system heats. This part is listed for the Baxi 224 Combi 2, 224 LPG Combi 2 and 228 Combi 2 models.
