We argue microscopically that helium-4 superflows carry heat unavoidably. We then show that a heterogeneous helium-4 superflow loop can be used to realize an entropy-decreasing process, thus providing an exception to the second law of thermodynamics. This exception is a quantum effect for its essential dependence on the quantum phenomenon of superfluidity.
