Is it possible to get a thermal store that will heat the incoming cold
water mains without needing a plate exchanger?

Yes. Our 'thermal store', which I converted into a heat bank (by adding
an external heat exchanger, flow switch and pump), can do exactly this.
It has a built in heat exchanger coil. Very long coil inside the
cylinder. You pass cold water in and it comes out hot.

You now have a hybrid thermal store. Why did you add a plate heat exchanger?
How did you pipe the coil/plate? How does it perform?
