I am going to replace my bathroom radiator with a Towel Radiator,we have a gravity system and the radiator in the bathroom gets hot without the central heating being on.Is this radiator being supplied with water from the hot water circuit only? is it just a case of draining hot water tank or is it on both circuits meaning draining the system.This bathroom radiator stays hot all night without the central heating coming on.The pump only runs when central heating on although the boiler comes on every now and then during the night.

this is a gravity hw, pumped heating.
as you say your rad is on the gravity hw side.
so it will be on the orange circuit instead of the red heating curcuit

no if you look at pic the loft tank supplys the system and both circults meet at the boiler heat exchanger.
