i HAVE A TOWEL RADIATOR IN MY DOWNSTAIRS BATHROOM ON THE SIDE OF THE HOT PRESS.THE BOTTOM OF THE RADIATOR IS VERY HOT AND THE TOP IS COLD I TRIED TO VENT THE RADIATOR BUT NOTHING COMES OUT NO AIR OR WATER ALSO WHEN THE HEATING GOES ON THE OVER FLOW RUNS FOR ABOUT TWENTY MINUTES THEN STOPS ANY IDEAS.

Are you venting the radiator with the heating turned off ?

Sounds like the system is pumping over through the vent pipe, have you altered any pipework other than the towel rail pipes ?

Pump setting been turned up ?
