  We discuss the statistics of heat current between two superconductors at
different temperatures connected by a generic weak link. As the electronic heat
in superconductors is carried by Bogoliubov quasiparticles, the heat transport
fluctuations follow the Levitov--Lesovik relation. We identify the
energy-dependent quasiparticle transmission probabilities and discuss the
resulting probability density and fluctuation relations of the heat current. We
consider multichannel junctions, and find that heat transport in diffusive
junctions is unique in that its statistics is independent of the phase
difference between the superconductors. Curiously, phase dependence reappears
if phase coherence is partially broken.
