Hi,

I've recently moved into a new house and when the water/heating comes
on at around 5am it makes a horrendous wooshing/bubbling sound which
appears to be coming from the heated towel rail in our bathroom
(located directly above the boiler). Strangely enough this only seems
to happen first thing in the morning and the bubling is much less or
even none existant during the day! (no really it is, I've even tried
turning the lights out and getting into bed during the day to do a
direct comparison to try to eliminate any psychological factors!). Our
boiler is around 8 years old, as that is when our house was built, and
the previous owners subscribed to that british gas thing to have the
boiler serviced regularly, so I'm hoping the boiler itself is
reasonably fit and healthy.

Anyhoo, I've tried reducing my pump speed, but this does not eliminate
the bubbling sound, just makes it a little less vigorous, also the
boiler keeps cutting out when I reduce the speed of the pump,
presumably due to overheating (which I imagine isn't healthy). This
really is driving me bonkers and has woken me at 5 am every single day
for the last 6 months.

I'm really hoping this isn't a dangerous problem, and I'd be really
grateful for any suggestions on what i can do to eliminate the problem
without having to try to get hold of a plumber.

Fingers crossed, and thanks in advance

If you've tried that, then presumably you've already tried bleeding the
radiators?

Cheers, yes all bled, apart from the afore mentioned towel rail which
does collect very small quantities of air.
