I've thought hard about this and will be installing a full bore valve at
the main feed to the store.

Whilst not strictly compliant, this will solve the problem.

In any event the store has 2 pressure relief points (one by the expansion
vessel and one at the top). I will also make sure the valve is disabled
so it cannot be casually closed.

Why do you think it's not compliant - sounds fine to me. The expansion
pipe
at the top is serving the purpose perfectly.

I am going by DPS' own manual which has words to the effect: "The expansion
relief valve must be connected directly to the feed input of the heatbank
without the possibility of isolation"

But hey rules are made for breaking....and there is another valve.
