Hello,
I've seen other people's posts on here, but they don't appear to be quite the same as mine.
My expansion tank is being warmed by water from the overflow. I can hear it dribbling in through the overflow, so it isn't submerged in the tank.
By elimination I now know that it only happens when heating my water cylinder. Both the radiators and cylinder heat up well. I've tried turning the pump down from 3 to 2, it slowed the water going into the loft, but it's still happening.
Layout of the system: The expansion tank is in the apex of the loft space about 3m about the hot water cylinder/pump which is on the top floor both of which are about 50cm above the boiler which is high on the wall in the kitchen downstairs.
Any advice would be greatly appreciated.
Graeme
