I have a problem with my central heating system. There seems to be a large amount of air regularly in the system, but strangely it cannot be bled from the radiators. It seems to travel round the heating circuit in large lumps of air.
The only place there is usually any air to bleed is at a bleed point in the hot water circuit.
Every now and then great belches go up to the expansion tank, and occasionally it sounds as though the pump is completely dry for a minute or two.
Often water can be heard sloshing down to the boiler. This all sounds pretty bad to me - does anyone have any ideas?
