Hi,

I wonder if any of you wise people can offer some advice...

We seem to have some air in our pipes/system. During the evening when the heating is on, we frequently hear some fairly load groaning noises from the airing cupboard and radiator in the bathroom. At which point I run upstairs as fast as I can and bleed said radiator - if I get there quick enough, I always get some air out. Despite having done this last winter on numerous occasions it doesn't appear to reducing.

I'm a complete numpty when it comes to plumbing/heating.

Any advice please?

I'm sure others will be able to advise more precisely, but I've always been told to bleed the system when it's cold. If you can imagine that your system will go in a loop from the boiler, round the rads and tank and back to the boiler. Start at your nearest rad, bleed it, then go round all your rads in some sort of order (doesn't need to be exact), go round twice to make sure. Crank up the heating and see how it goes.

Like I say, someone else will give more details, but I'm a bit brain dead right now to be any more exact..

No help- but we had this and our builder left the house as he was convinced it was haunted. We could have got Derek Acorah in there and made a packet...

are you refilling the system each time you bleed? via mains filler loop.

Not sure this is relevant, but i stayed in a flat which had clanking radiators. We tried bleeding them to no avail. Turned out the radiators had been put on the wrong way round, and this was causing the racket!

No - is this required? What/where is a mains filler loop?

I will try the cold bleed suggestion from MacFlat.

Thanks for your responses.
