Thanks Neil, that makes me a very happy bunny!

the reason is, my current boiler and hot water tank are in the kitchen and
there are 2 cold water tanks in the roof of the bathroom.

I will soon have finished my big workshop and will then attack the
bathroom, but my plans do not want the cold water tanks in the roof still,
so that is why I am happy!

No ... no tanks .. mains cold in- hot water out .... the heating
circuit is pressurised by the mains pressure via the filling loop
then held by a small pressure vessel within the boiler case hence the
warning labels about not operating at less than ~1 bar. .... Neil
