I am looking after an empty house, when I started up the boiler it sounds like the fan bearings are very worn. During the cold winter it was run daily, and I did not observe this noise, but it has mostly been standing idle now that it is warm. Can the motor be lubricated or serviced, or will it need a new fan assembly?
The house is going to be sold and no doubt the buyer will want to fit a new boiler, so it does not warrant much expense.
