One noisy upstairs radiator

[Qzwxec10]

Hi all,

I registered on here with the hope you’ll be able to help me.

I have one radiator which when the CH is turned on it makes a loud rushing noise (the only way I can describe it) it’s loud enough to wake you up in the morning.

The only way to stop it is by turning the pump down but then the rads furthest away from the pump will only warm up slightly.

The rad in question does not have a TRV, it’s just the normal valve and is the first radiator in the cycle.

This is the only radiator with any issues and all of them have been bled.

Thanks all.

Try opening the valves a bit more

The valve on the rad in question is fully open.

The other rads which all have TRV valves attached are all set to 5 (highest number).

Both sides are fully open ?

Both sides are fully open ?

The lock shield Valve on the problem rad is only open about half a turn, I can fully open this though if that’s what you mean!

Yes please but have the noise happening at the time you open it slightly

Sorry just to clarify, the heating should be on as I open the lock shield?

I appreciate your help so far.

Yes with the radiator making the rushing noise

Yes with the radiator making the rushing noise

Both valves are now fully open, the noise is still here

Any difference in the noise ? Also if you turn one off noise goes away or keeps going ?
