I have just done a bit of work on my central heating system.
I re-routed some pipework and added some new radiators.
When the system was refilled there were a few problems with air locks.
I bled the system at the highest points and this seemed to cure the problem.
All the heaters gained their desired heat and hot water tank heated to correct temperature.
After a few days I noticed gurgling sounds coming from some of the radiators.
I bled them but the same problem came back after another few days.
Air seems to be getting into the system from somewhere.
Could anyone tell me if air is getting into the system because of the way the system is set up?
Could it be that the pump is set to high? (Grundfos UPS 20-60 on setting 2 at present)
I have attached a drawing of my central heating system.
