I have just checked HRPC online (thanks for you commenting elsewhere that
they had an online site). £197 for the correct potterton retail 13.5L
expansion tank .....gasp ...... Even trade will be pricey. I see they have
Altecnic 18L at £39. The max working bar allowed is 4 so still should be
OK.

Looks as if they have to be fitted the correct way round. Would not have
thought of that.

Perhaps it would be cheaper in the long run to put a well lagged radiator in
the loft and keep it filled with air!!!

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

A dreaded Potterton Flowshure+ hence integral but (for once) easily

normal to
get the shape that fits. If so could be a good idea to fit an external
one
for that price.

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.
