Lost me too! I can see why some people have a preference to putting it and half open, but this efficiency thing I cant buy. Water running through the HW cylinder will dissipate heat into the hot water regardless of the speed its travelling, ok more energy will be dissipated per volume of...

Yeah ok I think I've got that. Is the idea to remove the 'height' of water such that the pressure is released so you dont get water creeping up into the header tank when on HW only for example? The other gate valve, on the return from the hot water cylinder, how much should that be open...
