If the customer wants a significant flow rate and you have downgraded the heat bank to 65C it will lose temperature quickly and deliver low water temp HW.
All depends on the storage capacity and the cylinder stat setting for replenishment and of course the size of the Hex .

What is an automatic variable cold mix valve if I may ask?
Do you mean a TMV ?.

Which leads me to another question..... Is it perhaps too high? Should I be looking to fit some sort of flow/pressure limiter on the TS? Advice please.
As to the ongoing "discussion" which has taken over this thread, I am genuinely interested in the system proposed by DrD, even if the technical issues you are all discussing are way over my head. Perhaps DrD could post a detailed plan of his proposals and the rest of you could constructively point out how it could be improved, if possible?
Thanks.....
