that is an expansion vessel, all that does is give the water somewhere to expand too
I still cant suss out why you would have a filling loop an expansion vessel AND a header tank,

you cant have both, unless he has a separate system that somehow uses the same boiler for a closed hot water system and an open central heating circuit, but i have never seen one of these. they are kind of mutually exclusive.

the powermax uses a thermal store for the hot water, they are fucking weird things, Ive only seen one of them and I was ripping it out so I didnt take much notice

if the mains pressure is not fast enough to fill the hot water storage to meet demand then i can see the need for a header tank, makes sense to me.
