The idea sounds tempting: In summer, simply send cold water through the Floor Heating – and the room will remain pleasantly cool. In practice, unfortunately, it looks different.

Because: The floor actually gets cold. And you notice it – especially on your feet. Everyone knows this unpleasant feeling of cold tiles or floors. The coziness that you actually want is missing. Instead of a refreshing coolness, an uncomfortable room climate quickly develops. Cooling via underfloor heating is technically possible, but rarely comfortable. It just doesn't feel good – especially not barefoot.

Especially in times of increasing hot days, comfortable cooling is becoming more important. But instead of cooling through the floor – and thus accepting cold feet or even a chill – modern systems rely on wall or ceiling cooling. 

The crucial difference: With walls and ceilings, our body hardly or not at all comes into direct contact. Unlike the floor, which we constantly walk on barefoot or with thin footwear, these surfaces remain "distant." This allows for gentle, barely noticeable cooling through radiation – without it feeling unpleasantly cold. This way, comfort is maintained even on hot days.
