Hi, I have a Vaillant Boiler.... rather old I fear, type VC GB 182E, after leaving it off this summer... (what a joke) I switched it on only to hear a rumbling... this doesn't appear to be coming from the pump, thats located elsewere.... It does sound like the fan contained within the boiler.
Has anyone had anything similar.. Quote for fan to purchase £160 plus fitting, need to ensure prior to purchase.
Cheers
Bob
