radiators get hot upstairs cold downstairs?

close all the returns down on the rads upstairs, then see if the ground floor gets warm,if that works then open upstairs by one turn then this will ballance the system,or do a reverse flow by using mains water,get the garden hose connect it to the tap then attache it to the ground floor drain point on the heating you should find one and then open the main and back fill as you doing that open one of the vents upstairs to let the pressure out this should blast it out or clear air in the system,good luck
