Noisy Ideal boiler

[brawbairn]

Hi, conventional Ideal boiler whistles (kettling?) when the burner is on - really noisy inside and outside house. All radiators hot and no apparent air in system. Problem may coincide with having extra radiator added to system - not sure.
Don't want to compromise system - should I be calling someone to fix it?

Thanks,

are there any radiators above the boiler (ie upstairs) if they are hot then youre system is full of water, if you live in a bungalow or rads upstairs are cold then there isnt enough water in the system - check the header tank.

If there is water in system then maybe the kettling is caused by a scaled up heat exchanger.
