I have just had a Worcester 18Ri boiler fitted to replace my old boiler. I also had the pump changed to a Grundfos UPS2.
The system is a Y type with a HIVE controller and has TRV's on all the radiators. It has a manual bypass across one of the radiators upstairs.
Would it be best to set the pump to a fixed speed or to a proportional pressure setting.
It's noisier than the old pump which doesn't seem right to me
