Having installed a Potterton Statesman oil fired boiler, with a Y plan
system, I have recently discovered, after about 3 months of running,
that the boiler now 'kettles' - or kettles just before it
thermostatically switches off.

It makes the sort of sound that a kettle makes, just before is starts
to really boil.

I have loads of treatment (including cleaner/descaler) in the system,
put the Grundfos Super Selectric pump on full, and opened all the rads
to full flow. It still 'Kettles' after a while.

If I ignore it, will it harm the boiler or shorten its life expectancy?

Thanks,

Ren.

Sounds like it doesn't have a pump overrun. The pump should continue
running for a short time after the boiler shuts down to prevent this.

I had kettling problems with my Statesman including loud banging and
popping noises. It started after about a year after I installed the
boiler. I injected a tube of Fernox superconcentrate central heating
protector which also prevents boiler noise in through a radiator vent.
It worked straight away and the boiler is now quiet.
