I'll ask again - more in hope than anticipation. Where does one buy the
type of mixer tap the OP has for a combined low pressure hot, high
pressure cold, supply?

Just bought a bath filler and basin filler from Boundary Bathrooms. Dual
control, 1/4 turn ceramic disc, monoblock, twin flow, suitable for low
and pressure systems. The key words are "twin flow" rather than "mixer".

On the OPs problem it may well be related to his fancy tap. It could well
be designed for high pressure systems only and thus will perform badly on
a normal UK HW tank fed (low pressure) HW system.
