Humming in heating

[StuckinRoystonVasey]

Hello, can anyone help.

I have constant, really irksome humming (like a helicopter in the distance) from central (District) Heating. It's a council flat, so I won't be tinkering with it myself. The council workmen say they can't do anything about it, which is maybe true, but I think they should send out for somebody who can.

Any ideas for what to do are going to need to come from me, so I'd be really grateful for any suggestions.

The noise is 24 hours. My heating connects to the district heating via an interface unit, and most of the noise seems to come from there, but it continues even when my heating is turned off. The maintenance men think it's the central pump, and they said they had turned it down, but if they did it hasn't helped too much.

The pipe work goes from the loft space, through the interface unit in my flat to the flat downstairs. I think when the old boy downstairs switches his heating off the noise stops, but I can't get much information out of him - I think he doesn't want the disturbance of work being done, or something.

I can't believe that in this day & age there doesn't exist a solution to the problem.

Any ideas, anyone?

Thanks!!

There might be a solution but before that can be found it is necessary to find out what is causing this noise.

I suppose you are one of those people who lives in total silence with no radio, TV or screaming kids so that you can concentrate on listening to the noise!

Do the radiators in your flats have Thermostatic radiator valves on the radiators ?

Seems to be unlikely to be the TRVs based on what he has said, Ian.

Hi Ian,

Thanks for the suggestion. No thermostatic valves, just the old-fashioned controls ( which don't work ).

Hi again Ian,

You may be onto something. No thermostatic valves in my flat, but apparently they should have been fitted around 18 months ago, before I moved in, so quite likely downstairs does have them. As I said, the noise seems to be on when the heating downstairs is on ( nearly always ) so there could be a connection at that.

Do you know of anything that could be done to the valves to stop the racket?

Thanks again

They need to be in the correct direction and on a normal system a bypass is needed. That is probably already provided by the communal system.
