have been ask to install a zone valve linked to a cylinder stat on the primaries from a gravity hot water boiler incorparating a bypass valve just before the zone valve.
everything tells me this is not the way to do this and something tells me it may not comply with regs.
I have always been taught that gravity pipes you do not restrict and the only solution is to convert to fully pumped.
Please can some one confirm if i am right or wrong please.
