Hi all,
Maybe there is an obvious answer to this. But I don't know what it is!
I have a newish Vaillant combi boiler, and TRVs on the radiators. On one of the radiators there is the noise of rushing water, but only when the TRV is turned up between 3 and 5. The noise isn't terrible, but enough to wake people up when the heating comes on in the night. Is this normal? I suppose one answer is to keep the TRV lower, but that doesn't seem quite right to me. I have bled the radiators twice. A bit of air came out of the radiator making the noise, but it didn't fix the problem.
Thanks in advance,
wrathkeg
