An infrared heater comprising;
- a mirror-like, semicylindrical reflecting plate,
- multilayer cylinder means composed of a combustion cylinder having a plurality of apertures uniformly spaced about the circumference and length thereof and a radiating cylinder having a plurality of offset apertures uniformly spaced about the circumference and length thereof and being in non-radial alignment with the apertures of the combustion cylinder, said multilayer cylinder means being arranged in front of the reflecting plate, and
- burner means for ejecting a spray of fuel into the combustion cylinder of the multilayer means, whereby no flame through the apertures of the combustion cylinder is blown off to the open air through the apertures of the radiating cylinder.
