If you do decide to stick with a vented HW system, and it certainly
does have a number of advantages,

What are they, in brief?

Consider a heat bank. Mains water pressure at the taps, so high pressures
showers and no pump, but no high pressure cylinders. Can be DIYed.
For an explanatioin:

then it is worth changing the
cylinder for a fast recovery type to improve HW reheat performance
while you are at it.


Can fast recovery cylinder only be fitted with a heat bank, not read about
them yet. Or do they work just in cojuntion with the boiler. Any links,
names or idea of prices on the fast recovery cylinder
