Glow worm boiler noise

[phil_076]

Does anyone know where I can find the decibel rating for the British Gas 330+ boiler?

I'm looking to get it replaced and wanted to compare it against the Glow worm energy 18r or 25r boilers (18W or 25W) or does anyone have any experience of these two models in terms of how noisy they are?

The Glow worm is a little less than 50 db, not the quietest but if that is a concern have it fitted in a cupboard.
