What is the difference between radiant heat and convection?

In addition, systems with radiant heat operate at much lower temperatures than systems with convection. Radiant heat therefore offers significant advantages over convection:

• The heat transfer is much more effective and can be felt much faster.
• The feeling of warmth on the human body is more pleasant and harmonious.
• The operating costs are lower thanks to the lower flow temperatures.
• Due to the lack of air circulation, radiant heat is allergy-friendly.
• Gain in room aesthetics, because conventional radiators can be dispensed with.

Typical sources of radiant heat include wall and ceiling heating and tiled stoves. In principle, the effect and thus the sensation on one's own body can be compared to a small model of our sun, or to the pleasant warmth of a tiled stove.
