What it is
The Viessmann connection hose for the expansion vessel (part number 7826474) is the flexible connection lead that links the expansion vessel to the heating circuit on Vitodens 200-W gas boilers. It carries system water between the vessel and the boiler's hydraulic assembly, allowing the vessel to absorb expansion as the system heats. The part is supplied under Viessmann part number 7826474.
