    any idea as to how to get air out of the system?

  • bath1959 Nov 30, 2008

    My new boiler 14 months old heats the rads on dual setting. for about 20 minutes then cuts out to \solid \red light. \sometimes it cuts out earlier when I TURN ON THE HOT TAPS. Sometimes there is hot water and sometimes not.



    When I put it on the summer setting (ie hot water only) the green light flashes i hear the boiler kick in when i open a hot tap but there is no hot water.



    This is frustrating for a family of four which includes a three year old. Its freezing and taking stress from my wife and kids,



    I have heard I may need to replace the thermistor or Venturi to fix the rad.



    Help. Anyone.

    Vokera Compact: Constantly have to reset it after about 30mins or will cut out if you try to put heating and hot water on at same time.
