Motivated by recent experiments [Subero, Nat. Commun. 14, 7924 (2023)2041-172310.1038/s41467-023-43668-3], we analyze photonic heat transport through a Josephson junction in a dissipative environment. For this purpose, we derive general expressions for the heat current in terms of nonequilibrium Green's functions for the junction coupled in series or in parallel with two environmental impedances at different temperatures. We show that even on the insulating side of the Schmid transition, the heat current is sensitive to the Josephson coupling exhibiting an opposite behavior for the series and parallel connection and in qualitative agreement with experiments. We also predict that this device should exhibit heat rectification properties and provide simple expressions to account for them in terms of the system parameters.
