Having read the details from a previous post going back to 2005 I thought I ought to finally do something about the above issue.
My family and I have lived with this problem for over a year! (I know, I know.....) We've all got used to the sound and sleep through it but we've just got a dog he goes mental when the boiler sparks up in the morning waking us an hour before we need to get up.
I could change it to come on later and use the dog as a very effective alarm clock but would rather get it sorted once and for all.
We had the boiler serviced back in the spring of this year and the CORGI engineer suggested it was the wrong pump fitted and it was leaking etc... and didn't want to get involved, so it was refreshing to see so many useful comments here. There is a bit of crud built up at the top of the pump which looks very old and it doesn't drip. The system has been installed for 10 - 12 years at least with us having 2 years trouble free after moving in and as I dread to add to the woe its been installed with microbore.
Seems the whole issue from the previous posts may be down to the Pump Overrun Thermostat. The boiler fires up, superheats some water which I can only imagine sends steam through the pipes, the pump stops and starts and after sounding like beirut for a few minutes then settles down and the house warms up.
The system was flushed and Fernox was added some 18 months ago when we had a shower fitted.
I have bled the rads and was considering draining the whole system, but really want to avoid this as the bloke who installed it in the first place doesn't appear to have fitted a drain valve.
Final problem, when we moved into the house I had no documentation for the system so whilst I can tell its a Myson Apollo I don't know if its a 15/30, 30/50..... and don't know if the part quoted in previous posts will work. Equally I don't have the details on on where to buy it and whether or not it is something I could fit!"
