It's an entirely valid thing to do.

In Fred Dibnahs day, yes.

It is overspecced for five main reasons.

a) I intend to install an additional shower room at some point.

b) By not taking into account boiler output, it is useful when run from
the
immersion, as it is at present.

c) If the calculations had been wrong (perhaps over optimistic from
manufacturer) it would cost a bomb to sort out.

d) It makes any destratification of the temperature profile less
important.

e) It does not significantly impact on the space used or the purchase
price.

Christian,

Now you can use the boiler with a flow switch on the bath and shower pipe
(the outlets with most flow), reduce the stores setpoint temp and also
reduce the boilers temp when heating the store. This promotes condensing
efficiency - the engineering to keep temps down. By default you may have
improved efficiency.
