Fluid will pass heat to the porous zone with the non-equilibrium model. However, the casing wall (fluid boundary) is not the same as the wall that's generated in the same location when Fluent add the overlay mesh for the non-equilibrium porous model. The two walls have no thermal links in the solver. 

Similarly the wall film models will see walls only (no porous jumps) and will see the fluid bounding wall and not the wall bounding the porous-solid zone.
