This Part taken from a used, fully functioning boiler ( VITODENS 100-W WB1B 26kW COMBI )refurbished and packaged protectively to ensure it reaches you in a ready-to-fit condition. As a used item, it is entirely expected that there may be some light cosmetic damage; marks on casing etc. although this will not affect the function of the part.
A large amount of other parts also available for this model and other models in the Viessmann range. Please contact us if you require a specific part and we can list it for you.
