Sealed system with vented hot water that also has an immersion heater (thank god). Having drained the system to move a rad on the first floor, the hot water is heating up and the first floor rads and attic rad, but not the ground floor rads. hmmm.....
The pipework for the groundfloor rads is below the drain point I was using to drain the system. I also had closed all the rads. Is it likely there is an airlock in the ground floor pipework? ....
How do I clear it!!!!!!!!!!!
Cheers
