Noisy new bypass radiator !!

[catnipsta]

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?

Open the valves more!

Fit a bypass valve if your boiler does not already have one , what model of combi boiler do you have?

not really such a thing as a bypass radiator, yes the one in the index room with the room stat should not have a trv but an auto bypass should be fitted if needed by the boiler manufacturer or systems design.
