My 17 year old Polyplumb UFH system is showing some reduction of flow across some of the ten loops (based on flow meter readings and getting one room in particular up to air temp)
I am also finding little movement in flow between some of the balance valves being fully open / closed so I have ordered a couple of balance valves, flow meters and actuators to see what changes. (on some circuits flow seen when room stat demand is off hence the actuators)
Is it possible to check the grundfos Alpha manifold pump flow pressure generated by fitting a small pressure gauge in the pump circuit.
Thanks
