My Potterton ProMax 24 He boiler starts up fine in the morning (ie starting up from cold) but on subsequent start ups it can start with a loud booming noise. I hear the fan start, then I can hear the ignition system clicking away. In the morning you hear a couple of clicks and then it ignites (quietly) but later in the day the clicks continue and the tension rises as I wait for the boom that tells me it's lit.
Is this a feature of Potterton boilers or is something wrong? I'd appreciate any advice.
Thanks
Ian.
