Header tank supply
Does the central heating header tank water supply have to be taken from the mains, or is it permissible for it come from the cold water storage tank ?
Answers
I don't agree. CH header tanks are invariably fed using a ball-valve type system to limit the flow to a maximum level in the header. A feed pipe put into such a ball valve will not operate unless there is decent mains pressure. You'd need a minimum of a 8m head of water to stand any chance of the valve working - unless you can devise another method of controlling it.
