I am presuming that you have fitted the radiator tails which go into the towel rail and on the valves correctly with ptfe,take off the tap heads and see if it is leaking around the gland packing nuts,if so and they are new, tighten them a pinch, it doesn't leak when it's hot as the heat makes it expand slightly.
