I recently had all my radiators replaced with new ones and had TRVs put on all of them. They are all siemens TRVs. The TRVs are beginning to annoy me because when they are not fully open or closed you get a constant whining sounds as the radiator comes upto temperature and the TRV is about to close. This sounds seems to last for ages. It dissapears if you open or close the TRV a little as expected. Is there any way I can fix the problem?
In addition, when the central heating part of my boiler comes on, it makes loud thunder sound for a few seconds like if it's going to take off! Does this indicate a problem? The boiler is only a year old. It's a potterton Performa 28i combination boiler.
