Hi, I had recently replaced my hallway bypass radiator (to a Stelrad Compact K1 & new Terrier lockshields). Ever since it had been installed, the area by the outlet-connection always starts to produce a sound (best described as kettle boiling water and hissing) after a certain period of time. I figured that this period is when other areas are warmed and the TRVs closes. So, when I close all the TRVs in the house, the noise starts as soon as this bypass radiator heats up. This radiator is fully bled.
My system is a unvented system (Worcester Bosch combi).
Any ideas of what this problem is? Just a badly made radiator in this case, perhaps?
