Hi
I'm doing a re-plumb of my bungalow, all the old pipework (mixed bag, copper & plastic, mish-mash of 1", 1/2 and 3/4 inch) is now in the skip!

I am running 3 zones from the manifold at the gas boiler - sealed system.

a) zone a - flow and return to three bedroom radiators, horizontally from the gas boiler

b) zone b - flow and return to three living area radiators, up from the boiler, into the attic, and down from the attic to the three rads.

c) zone c - flow and return to the immersion heater, up from boiler, into the attic, and down to the hot press

Question is, can anyone please help me with the pipe diameters I need.

I'm presuming I use 3/4" qualplex everywhere?
