What it is
The Viessmann expansion vessel hose (part number 7822350) is a flexible connecting hose that links the expansion vessel to the heating circuit on Vitodens gas boilers. It carries system water between the vessel and the boiler hydraulics, allowing the vessel to absorb expansion as the system heats. This hose is specified for Vitodens appliances from 14.01.2005.
