An infra-red heating apparatus includes a radiating surface and an adjacently located black body receiver spaced from the radiating surface. A fuel supply plenum is located adjacent to the radiating surface to provide jets of fuel along the radiating surface to be ignited thereby. Fins of heat radiating material are attached to the black body receiver and project therefrom into an air duct. Air moving through the air duct is heated as it passes over the fins.
