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,
