Thanks for all the info folks.

A generic tank on the return it will be.

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!!!

Using a rad is temp solution. Use a proper pressure vessel.

Agreed, there are issues withthe air disolving into the water and coming
out elsewhere, if nothing else.
