We predict an anomalous thermal Hall effect (ATHE) mediated by photons in networks of Weyl semimetals. Contrary to the photon thermal Hall effect in magneto-optical systems which requires the application of an external magnetic field the ATHE in a Weyl semimetals network is an intrinsic property of these systems. Since the Weyl semimetals can exhibit a strong nonreciprocal response in the infrared over a broad spectral range, the magnitude of thermal Hall flux in these systems can be relatively large compared to the primary flux. This ATHE paves the way for a directional control of heat flux by locally tuning the magnitude of temperature field without changing the direction of temperature gradient.
