A few months ago I required a fan for a Worcester Heatslave 9.24 boiler which I was told was obsolete. After scores of phone calls to spare part suppliers and having no luck, a collegue at work gave me a number and I finally aquired the last one that they had on the shelf. I have since had a new boiler installed but kept the fan from the old boiler. I paid £80 for the fan and am open to offers for the nearly new one.
