Hi All I just installed new combi boiler after decommission an old back boiler I capped the flow and return connections and which were in fire place. I picked the flow and return from the radiators in kitchen close to the boiler when I commissioned the new boiler I had no heat up stairs should I joined the old flow and return together? All pipes are under the floor and carpet I can't see the old the pipes connection your advise will be very appreciated. thank you:sweatdrop:
