I am sure I can hear air in the CH/HW system at the pump on start up, after a time it does diminish but not go completly. I have tried bleeding all the air vents and rad's also the pump but all I get out is water.
does anyone have any ideas on what might be causing this, how to bleed the air from the system?
Thanks
Mike
