Noisy TRV
I have 3 noisy TRVs as they are fitted on the return instead of the flow.
The instructions suggest this should be okay but they buzz as they close. Rather than change ends (requiring 4 joints to be disturbed on each rad) is there any disadvantage in rotating the valve to a horizontal plane - thus putting the flow onto the 'base' of the valve? |

Should be fine. Actually, it's a better mounting position for anyone who is going to struggle to bend down to read the setting on the front - I recently installed some in this position for an elderly relative for this reason, so they can read the setting from above. Make sure it's not sticking out somewhere where it's likely to get knocked or walked into though. -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

Noisy valves seem to be an issue a lot. a place where I go has one in a
studio, and this means it has to be shut off during recordings. We call it Hissing Sid, well we are little children at heart...

Another thought - have the TRVs been fitted without ensuring the boiler has a bypass route for when they all shut off? Is there a radiator which doesn't have a TRV and can't be turned off (lockshield at both ends)? -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

Is there a radiator which doesn't have a TRV and can't be turned off (lockshield at both ends)? There is one rad with no TRV and whilst it doens;t have lockshields both ends, it will not get turned off as it is the important hall radiator. |

Is it a large radiator (which is likely to be set with a good flow through it), or a tiny radiator which might have the lock shield only open a crack (assuming the system has been balanced)? When the TRVs start making a noise, I would try opening the hall radiator's lockshield, and see if that stops it. Note exactly how far you opened it, so you can set it back to where it was again. When you have a radiator as the bypass loop, particularly a small radiator, it may be that you have to increase the flow in it above what is ideal for balancing, in order for it to cope with the flow needed to maintain the bypass. Is there a thermostat in the hall, to prevent the boiler firing when the house is up to temperature? -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

The noisy ones are in 2 bedrooms and these are usually the only ones to normally close. |
