Noisy Radiators! Please help!

[Brian0782]

Hi

I'm new to this forum and the only reason I've joined is so somebody can help me with noisy radiator issues!

We moved into this house in March and we've been experiencing issues with two radiators in the upstairs bedrooms ever since.

We can hear the sounds of water sloshing and some other weird noises.

We have an Ideal Atlantic 24 boiler and these two radiators are brand new. TRVs have also been replaced recently.

Our system has been power flushed after we moved in.

My OH thinks it's to do with the pipe work whereas I'm thinking it's the boiler.

It could also be air in the radiator but would it make these sounds?

Also we have a radiator in our house that doesn't even get any heat. Engineer said its a dead pipe. Wondering if it's related to that?

I'm at my wits end here.

I've uploaded videos to help.

Can some please help! Thank you

Ah, so that rules out my question to Shaun. Sorry I'm a burner service and repair technician, I'm not overly familiar with designer radiators.
Have you tried bleeding the radiators, have you had air problems before?
