SYSTEM = Glow Worm 30 cxi combi & 6 rads.
The TRVs in the house that we have recently moved in hiss loudly at various settings. We have resorted to turning all TRVs to max (which obviously defeats the object of having them), but some still hiss, especially when the heating has been on a while.
Will a differential bypass valve solve this? Or, would it be allowable to fully open both valves on the hall rad that doesn't have a TRV? Would this work? Why are the TRVs hissing? Any other suggestions welcome.
Thanks
