when boiler fires up it sounds like a jet plane taking off is this a fan problem or blockage in flue any ideas.

also i have noticed that a couple of the radiators are on all the time even when radiators are not selected on controller,could this be 3 position valve stuck open.....any ideas on that one too .............cheers in advance

Sounds like it is backlighting.> Burning from the jet rather than the burner. Usually a soft lighting fault with the gas valve. You need the pressures checking out by a Corgi engineer.

Probably the case but it is possible that your system has been plumbed with a heat sink radiator in the primary circuit and then someone has added another radiator.
Has this just started to happen or has it always been like that?
