    Upstairs rads need constant bleeding.
    Could this be caused by the supply tank being too low?

    Have a look at the ballcock in the small tank. Is water coming out of the ballcock? Even just dropping ?

    Yep Dtp - the ballcock is working fine.

    The height difference between the water level in the tank and the upstairs rads is only a couple of feet and they require regular bleeding. I was thinking of raising the tank and so increase the pressure in the system. Would this work?

    The tank you are talking about , is this the small tank as opposed to your larger main tank , if so , what DTP wanted to know was is the ballcock in this dripping , or flowing , if it is it means you have a leak , the need to constantly bleed rads means that water has gotten out somewhere , so by bleeding your rads you are introducing fresh water which is rotting the heating system from the inside out , tie up your ballcock in the small tank and see if the water level drops , give it a couple of days and you will see if you have a leak .
