Biasi Riva Advance 32 pump whine

[Draughtsman]

No really apparent close to the boier, but the noise comes from the pipes and rads all over the house. Is it possible to alter the speed of the pump and get rid of the noise that way?

Or is it just what they do? I remember other pumps making a noise but they were a low, deeper hum, this noise is quite unpleasant.

Looks like a fixed speed pump on that model.

I just leave the hall stat at 16° when I have the heating on, then it seems to be bearable.

Actually, 15° is even better.
