Isn't it illegal to mount a boiler on a party wall for this very reason?

Wish it was. Next door's one is on the party wall - although in what was their outside loo. The pump 'hums'.

Another reason for disliking system boilers. ;-)

Oh yes they have. At least with the 130 which is, I think, essentiall the same boiler but less output. It is a known problem. Keston mak excellent boilers but I think this series was essentially for ligh commercial use where noise isn't so much of an issue.

In the case I had to deal with, the majority of the noise came from th air inlet pipe (50mm mupvc). Keston do a silencer which is plastic an about the size a baked bean can which goes on the end of the pipe. Tha helps but not much. Worth a try.

As is varying the length of the flue to minimise resonance / harmonic in the inlet pipe.

I ended up running the air inlet pipe downwards and into an enclosur which I built. It's similar to a loudspearker enclosure with a baffl and lined with 25mm thick high performance acoustic foam. The front i removeable. The air inlet pipe comes up through the floor of th enclosure, which is wall mounted. It is a big lump because it needs t be lined, have a baffle, be openable (for cleaning) and cause n restriction to the air flow. Vital.

It's pretty effective but can't eliminate all the noise.

NB: It is illegal to modify any gas appliance flue unless you are CORG registered. And get them to read the mfrs instructions regarding th flues!

Good luck
