You amaze me. I am getting used to my boiler costing a fortune.

If the one in the boiler is easily exchanged (they usually are very
inaccessible) then the manufacturers replacement is worth paying the extra
(probably double) over a generaic component that would have to be fitted
elsewhere.

If you do replace it with a generic vessel, fit it on the return pipe.
