Anyone know what causes the noise in the video. It only affects 3 downstairs radiators and upstairs are fine. The sound in the video is not that accurate, it's more of a tinkling/buzzing sound. 2 of the rads replaced but no difference. Very little sediment came out of the rads.

Re: Noisy radiators
Vibration in the end/top panels that are usually just friction fitted?
Re: Noisy radiators
No vibration it seems Alun, they have plastic tensioners on them. It's more of a tinkling sound, but fairly loud, which is why I was expecting lots of rusty particles to come out but didn't find any. That seemed the likely culprit to me but apparently not.

Re: Noisy radiators
Might they be the first three radiators after the pump? If so, is the noise louder in the one nearest the pump?
Re: Noisy radiators
Pump is in the loft with the boiler so these are the furthest away. Only thing I can think of is to drain and refill the system but was trying to avoid this.

Re: Noisy radiators
It could just be the sound of the water circulating inside the radiators.
As Dave says, try turning the pump speed down to see if that makes a difference. It might still flow well enough with the speed set a bit lower.
You could also try adjusting the lock-shield valves, on the opposite end of the radiators to the TRVs. Has the system been properly balanced with the lock-shield valves?
