Would a heat bank be a better "storage heater" for your application?
Charge on E7 electric, but then use the heat when you want via the
existing wet CH system?

(to improve further, perhaps the heating could be done via heatpump
rather than directly from the E7)

That is certainly worth looking at. You do need a large store for it
to be viable though, think 1000 to 1500l.

That's one thing we do have - *lots* of space.
