I didn't say that a condensing boiler is technically quieter then a

Oh - I'm not disputing that. However, kettling isn't inherent in a non
condensing boiler - it's a fault.

More likely in cast iron boilers

'Kettling' is the water in the heat exchanger boiling.

It is clear you know sweet nothing about boilers.
