It the first time I have had my HW system on and after solving the sticky thermostats I still have the problem of last year //www.diynot.com/forums/viewtopic.php?t=45399&highlight=
Basically all 4 radiators in the flat are working fine and are balanced. All have been bleed. The pump pulls the water through the systems as opposed to push. See http://www.cydodimead.co.uk/jpegs/Pipeworkcopy2.jpg The final radiator in the system is the bedroom. There is a sound of air/wooshing/gurgle type noise from the pipework from that radiator to the pump everytime the pump is running. Having drained the system at the end of last winter and then filled it back up again and bleed all the radiators etc I can't see how there is air in just that single pipe. Is it air in the pump or pipe?
Any clues on how to get rid of it?
