Hi,
I've been searching for a while for an answer to this. Had heating engineer out today to look at the boiler. Problem is that the pump is coming on at 2AM, 4AM, all hours. The rads upstairs have their valves open only a little so the water's quite audible. Apparently, this is the overrun from the preheat. The strange thing is that it's pumping for 30-40 minutes. The engineer's solution was to turn off the preheat, which hopefully will stop us waking up in the night (there's clanging too, but that's another story). Obviously, that means water's taking longer to heat up - not a massive problem - but if someone gets up in the night and runs the hot water, the pump stays on for ages.
Any ideas?
Boiler's an Ideal Instinct 30. Three years old, serviced every year.
Incidentally, the clanging has gotten worse recently. The engineer said it was rubbing pipes, but I'm curious as to what else it could be. Air in the system?
