noise in radiators

[maggie]

I didn't know there were 'other bleed points' in the system. Where are they: if my hissing TRVs are just the air in the system I am determined to get rid of it !

They could be anywhere. They seem to lurk in the airing cupboard, but I've found them hanging out in lofts, and sometimes hiding under the pipe insulation. Don't make too much noise when you go looking for them as they will hear you coming, and hide.

I suppose it could be just the restriction in the TRV causing the noise. A bit like the mains tap being just open. Is it that sort of noise?
