Long term noise levels Worcester Bosch 28CDi vs 30i

[MRH2]

Hi

Choosing a new replacement Worcester Bosch combi boiler - both are about the same price.

Anyone have experience of what the noise levels are like - the WB website says 52 decibels for the small one and 50 decibels for the larger - but what are they like in real life over the longer term?
About the same?
Do the (assuming more compact parts) in the 28CDi get louder more often for example?
Perhaps there are more prominent tones in the smaller one?

Thanks in advance for your help!
Cheers 🙂

TBH there about the same Both good boilers think the 28 cdi compact has slightly better hot water flow rate
