Hi, I am having problems with 2 upstairs radiators not getting hot also the boiler is making a noise which sounds like a bird flapping around inside, I think this is what they call kettling ?.
took problem rad off the wall and ran hosepipe through, replaced TRV with regular valve and re-hung [problem stays the same]. I have bled air from all rads, pump and any other vent unions I could find. Tried balancing the rads - no change. If I turn all rads off except the problem one it will get hot which leads me to suspect the pump is faulty rather than a blockage - would you agree ?
This is starting to drive me crazy !
