Found 3 pieces of advice on plumbers forum on the web...
1) Constant bleeding is damaging to a system if the inhibitor is not replenished. Air in a sealed system is usually hydrogen associated with system corrosion. Air cannot be drawn into a system which is pressurised.
2) Do you by any chance have a Chrome/Towel rail in the bathroom? These have notoriously bad valve seals that let in air.
3) Go round and have a very thorough check of all the radiator bleed and blanking plugs, the valves each end (take off the TRV heads and wheelhead caps...check the spindles), check the pipework connections...you have microbore so more chance of leakage. Towel rails are notorious for having junk valves...check the spindles and the tails where they screw into the rail.
Given you gave the pump a hard time the seals could have failed on that drawing in air. The system pressure has been dropped many times and the auto air vent may be leaking. Also check the pressure relief valve pipe through the wall for drips.

Thanks for that
