however, we noticed a fairly loud buzzing coming from the bathroom -
the radiator was vibrating and this appeared to be the source of the
noise. The radiator in the adjoining bedroom was also vibrating, but
much less so. The noise appears to be linked to the pump, but the
boiler itself does not appear to making any unusual noise.

sounds like vibration from the pump via the water to the radiator.

May be the first sign of a failing pump?

Thanks TNP - I hope not, as this boiler is only 18 months old...


swarf in the pipes can lead to early failure..

All installations have an inverse valley shaped reliability curve.

In the first year installation and manufacturing defects show up. After
that they are reliable until the parts age...
