Sounds like an Elson tank, does it have a big brass valve below it with a plastic cap on it(cyltrol) ?

No , I mean a valve , normally on the return pipework or can be attached directly onto bottom of tank.

if i,m correct this is one of those air pocket in the cylinder systems cant remember the name. the air pocket separates the haeting from the dhw the problem could be with that part
bye the way the backbioler is baxi and i think it should have a 3 port valve am i right?

sounds like an Elson.
the primatic part (locally known as the witches hat) has a blockage on its feed pipe. with difficulty & a wet arm this can generally be cleared. if not there is a temporary way to get it to work before renewing it (but i cannot premote how to do that on this site).
