I have flow through header tank this is causing condensation in my loft as its quite hot water flowing. Its not just expansion but a constant flow, as much as a hose-pipe with the pump speed to max.
I have tried adjusting flow of pump down When I block the feed from the tank to the system with my finger the flow stops.
if I block the vent which has a slight pressure obviosly the flow stops, my vent 22mm and feed 15mm come from the middle of the system pipework on the common flow and return before the 3 way valve is this the problem, and they need to be re-routed to the boiler.
Thanks in advance.
