So I had a new boiler installed (an Ideal Logic 24) and while my heating is now running much more reliably, and the boiler itself is much quieter, I hear water noise in every room, whereas before the system was almost silent. I suspect that the pump in the new boiler is circulating the water much faster than the old one. Is it possible to turn the speed down (I understand that for this model, unlike my old boiler, you need to be corgi registered to even open up the cover, so I can't even look myself to see if there's an adjustment)? If not, is there anything else that can be done to get rid of the noise?

Nope you cant turn down the pump speed of the new boiler and you are correct in your assumptions of the new pump being more powerfull, you need to get your installer back to either balance the system properly or set your system by-pass correctly
On any noisy radiators ensure you open both radiator valves fully. That should keep it quiet.
