Hi again, sorry for delay. i changed the pump and house is heating up better. I have sighted the flow from the boiler to the three way valve and pump and its 28mm. After that its 22mm with 15mm spurs to each radiator. The flow and return to the DHW is all 28mm. I have noticed 5 TRVs appear to be...

rechecked boiler flow and return after its been on for couple of hours. Flow 72 deg c return 56 deg c using a raytek IR thermometer gun.Boiler set at 75 deg c. tks Andy
