  We investigate the radiative heat transport along a Su-Schrieffer-Heeger
chain of InSb nanoparticles. We show that in the topological non-trivial phase,
the edge modes dominate the radiative heat transport despite their strong
localization at the edges of the finite chain due to a long-range coupling of
the first and last particle. We further discuss the scaling laws of the heat
transfer with respect to the chain length for the longitudinal and transversal
band- and edge modes and conclude that both type of modes obey the same scaling
law.
