But the performance of unvented depends on your local pressure and flow

I have used pumped, unvented and heat bank systems. Each one provided a
fantastic shower at high pressure, and not flow rate limited.

What about the options of either a break tank and pump, or a
large accumulator?

How do the costs etc compare?
