Myson Apollo Boiler

dougie22 · 18 May 2007

Hi, My boiler fan or something comes on for 30 seconds every few minutes, the boiler looks quite old but i cant afford to change it at the moment, i have had a couple of people come round and they said there should be no real need to change it but they dont know why the boiler makes this noise every few minutes, it does pump air out the fan in the wall so i can only assume that its the fan coming on or a pump of some sort, the flame doesnt light up at this time so i am unsure as to what it is. when the boiler is on it is quite loud so this noise is really annoying.. i have to keep it switched off at the mains so it doesnt come on but his means i cannot use the timeswith.

can anyone shed any light on this please..

I could have sworn I replied to this last night.

What model Apollo is it?

Some fan-flued Apollo's have a permanent pilot which means the fan runs every so often to clear the products of combustion of the pilot flame. Do not turn off the mains supply to the boiler.

If the fan is noisy then it probably needs replacing. Is it noisy when the main burners are on?

dougie22 · 18 May 2007

yes the boiler is noisey when it all goes on, i have to switch it off at the mains as its soo noisey and my bedroom is above it and it would keep me up all night otherwise.

so you think that is definitely the problem, is it a hard job to fix?

Not exactly difficult to change a fan depending on what model it is. Can you advise?

If it's the one I'm thinking of then the only shock will be the price of the replacement fan.

Yes, not cheap.

And new holes may have to be drilled (in fact they will have to be)

Self tappers will sort that out

well i hope its not the one you are thinking of, but it says the apollo fanare 15/30 - 30/50 or 40s, not sure which one it is tho.

so it is natural that the fan will keep kicking in then? its soo annoying

Soggy_weetabix · 18 May 2007

Yes it will. Its a perm. pilot fan flued boiler. The fan needs to clear the POC (products of cusbustion) or the pilot will continally fail.

Same as a glowworm swiftflow.

Im guessing you have only noticed it as the fan has become noisy?

Dougie, I'm afraid it is.

Yup. That's about what I was quoted (trade) by Partscenter when my brothers fan bit the dirt. Jammy so and so got one for nixies through a guy at work. Doesn't Raden do this sort of thing?

dougie22 · 19 May 2007

thanks for all the help guys, even if its not what i wanted to hear, no the fan ahs always been noisey since i moved in 1 yr ago, thought it may have been a faulty timeswitch switching it on but ive put a new one on, been doing the kitchen up you see so through winter struggled with no programme, boy was it cold.

dougie22 · 19 May 2007

jesus!!!!!!!!!!!!!!!!!!!!! £300!!!!! might as well get a new boiler

gas4you · 19 May 2007

And retail is £370 + VAT which is what you would probably get charged plus fitting if you had a CORGI in. So it is still relatively cheap

Agree though that with age of boiler replace with new one and upgrade system to comply with latest regs. Ball park figure around £1600-£1800 + VAT.

Still seem expensive for fan

If it can be removed, raden can recon it.

We have the same problem with our boiler (same model). The fan comes on every 4 minutes exactly and it keeps me awake as its next to our bedroom. A plumber looked at it recently and said there's nothing he can do so we'll have to put up with it until we can afford a new boiler.... I share your feelings of annoyance!

giblets · 22 Jun 2007

Sam4, that boiler fan runs every so often to clear the products of combustion caused by the pilot. It is normal operation for that model.
