My brothers 10 yr old combi boiler is kettling on hot water demand, the central heating is fine, no kettling at all. The heat exchanger and the system has been descaled/flushed.
We both have the same combi boiler, got a deal at the time. Mine was doing the same thing after 10yr but a descale cured it.
Any ideas please
Thank you
