Now that the weather has cooled off enough to have the central heating on again in the morning, I've started noticing some stranges noises coming from the boiler itself shortly after startup and also whilst it remains on.
1) About a minute or so after the CH side is switched on I can hear a sound what I can only loosely describe as what a steam train would sound like before it pulls away from a station. A low rumbling that builds up, changes to a higher pitch, stays that way for a few minutes and then just disappears whilst the CH remains on.
2) Whenever the boiler decides the radiators need "topping up" to maintain their temperature I hear a single click noise shortly after the fan starts. This single click noise gets louder the longer the system remains on. This noise happens also happens when a hot water tap is turned on. We never paid much attention to it during the warmer months as it was nowhere near as loud as it can get now that the CH is also on.
3) Along with number 2) above, the boiler also sometimes makes a vibrating sound. I place my hand against the case when this happens and most of the time the noise seems to be surpressed. However, on occasion it seems that this noise happens regardless of whether my hand is pressing against the case or not so it doesn't appear to be a loose fitting cover.
Just to give some more background info...
This is an Alpha HECB33 that was installed at the start of this year so still under guarantee. It's the first time I've had a boiler installed, since the last one "came with the house" and so I've not had to deal with boiler guarantees, warranty etc in the past. Before I phone up Alpha and give them the above info to arrange a visit I have a question that I hope someone can answer so that I know roughly what I might expect them to offer...
Despite being under guarantee I'm not expecting Alpha, or indeed anyone, to give a free repair. However, I've looked through all the Alpha documentation that I was given at the time of installation and I cannot seem to find anything referring to what might or might not be offered when it comes to issues experienced during the guarantee period. Does anyone know?
Thanks in advance
