This morning the boiler started making noises. When the fan starts
spinning it makes a noise. I don't know how to describe it. A howl is
the best I can describe it but that suggests it is loud and high
pitched and it isn't exactly either of those. Once the fan has been
spinning for a while, the noise seems to go away. Perhaps the fan
expands as it gets hotter and that somehow stops the noise?
I can get to the back of the fan and I have sprayed some white grease
onto the bit of the fan I can see but it doesn't seem to have had any
effect. Where is the bearing that I need to lubricate? Is it at the
"far end" of the fan, that would involve having to dismantle things to
Are these known symptoms of a failing fan? I presume the grease has
dried out with age? I know Geoff is recommended in these parts. Is it
time to buy a new one from him?
I would like to get a new boiler one day but I currently have a combi
and I would like to change it either to something with a cylinder, so
that I have backup hot water, or possibly I might look into a heat
bank. I would also like to move it to the other side of the kitchen. I
was hoping I could re plumb the water bits, add the cylinder and
header tank etc. myself, before buying a new boiler, to keep the costs
of the replacement down. As it will take me months to get round to it,
I was hoping to keep this boiler going for a bit longer.
My question is, how could I get a gas qualification, so that I would
be able to do all of the replacement when the time comes? A quick
google suggests I need a to start with an NVQ level 1, then do NVQ
level 2, then NVQ level 3, and then spend several hours under the
supervision of a plumber. That's great if you want to go into it
professionally, but I think it would take too long and be too
expensive for a DIYer.
