Please can anyone answer 3 questions about central heating?

Also I wasn’t being funny with my first post. I was wondering if you had an update

do you have TRV's on radiators where room stat is ? are your radiators sized correctly ?

do you have TRV's on radiators where room stat is ? are your radiators sized correctly ?

Interesting you should ask - I do have TRVs on the rads where the room stat is, but I didn't until the first engineer drained and refilled the system and fitted them. However, the 2nd engineer wasn't concerned about them. I believe the rads are sized correctly.

Shouldn’t have TRVs in the same room as the stat as they will constantly fight against each other

I would say take a video of this sound but we will obviously never get a true representation of it. I would be very surprised if the water was boiling as your boiler and system would be bouncing off the wall from memory I believe you said you had some TRVs changed I think you have to start there

Thanks. I recorded the noise on my phone and it wasn't representative of the noise. The replies on this forum keep coming back to the TRVs, as you said. The original engineer fitted TRVs where there hadn't been TRVs.

Thanks again. That's the message I'm getting on this forum. If I was handy, I'd remove the TRVs (I know it's not that difficult to do, but I couldn't do it). I'll ask an engineer. Interesting that you say the noise isn't likely to be caused by the high temperature of the water. Appears I can discount that as a cause and go back to concentrating on air in the system and/or the TRVs.

And as was said in your original thread the stat shouldn’t be in the same room as TRVs

Is the stat wireless

 

[Martell]

Combi or conventional hearing system??.

Combi (Worcester boiler 3 yrs old)

Is the stat wireless

Yes it's wireless and not located near rads

I believe you said that the stat was originally in the hall with no problems. I’d be tempted to put it back
