Radiant heat works on the same principle as solar heat: a heat flux(flux) directly heats all the surfaces it encounters. These surfaces then emit heat themselves. The air in the room heats up only secondarily, via micro-convection around the heated materials.

Radiation thus directly heats all bodies, walls and objects in space. When radiation is emitted at a low temperature, it is referred to as "soft heat." This provides a quick and pleasant heat experience, which is perceived as very comfortable by those present.

Dark radiation tubes use infrared radiation to heat buildings efficiently. They consist of gas burners that, via fans, produce a flame inside a steel tube. This tube is heated to a temperature of 200 to 600 °C, causing the tube surface to emit infrared radiation.

Heat is directed to the desired areas using reflectors placed above and beside the tubes, with some types even thermally insulated for optimum efficiency. The flue gases produced during combustion are safely discharged to the outside through an exhaust system.
