Might want to measure the O-ring with calipers. They're a mass-produced catalog item; I suspect that Buderus didn't have a weird one custom made at great expense. If you know the (new) dimensions and material (do NOT substitute a different material!), can probably get them for a lot less.
Has to be an exact match.

how do u get the fins so clean ? what product ?

[@ookdanog0]

Onion holder stainless steel and nefit protector fluid (helps to keep it clean).
The fluid is actualy ment for professional use .
You hardly get it fully cleaned if its severely clogged-up.
