It is also imperative you use a stainless steel towel rail because the water in the hot water system is aerated and has no corrosion inhibitor in it as the closed system CH system does.
It can be done, but in view of the hassle I agree with Stanleymans solution.
Using the cylinder water would simply lose the stored hot water and be even more complicated. He does mean connecting the towel rail in parallel to the cylinder heating coil but this is only on when it is heating water, one or two hours a day.
It can be connected before any motor valves but will still only work when central heating or hot water is called for unless extensive modification of the pipework and wiring is carried out to create a separate zone for the towel rail.
Some towel rails can also have an electric element fitted for summer use but as there is already a radiator in use, it is still simpler and much less expensive to use an electric towel rail for all year timed use.
