Typical, Christmas Eve, get in from work, house cold.
I have a Glow Worm Ultimate FF boiler. I've always thought it a stupid idea having a fan in the hot gases from a boiler (yes I know, all the power stations have them, but they probably have guys with oil cans at the ready) and I've been proved right. The fan has seized up. A little oil in the bearings has got it going again in the meantime, but do you really have to replace the whole unit - fan, case, little pipes for the pressure switch, or is there a way of replacing the bearings?
If it is a matter of buying the whole unit, where's the best place to buy it?
