System comparison

The following visuals compare the energy levels of radiant systems and air heating systems.

Firstly: When heating with radiant ceiling panels, the perceived air temperature is the same, even though the actual air temperature in the room is lower. The result: The lower temperature gradient between the temperature of the indoor and outdoor air means fewer heat losses.

Secondly: While the heated air produced by air heating systems rises, radiant ceiling panels create heat when the radiant heat comes into contact with people and objects (surfaces). This produces a more even distribution of temperature across the full height of the room and therefore consumes much less energy.

The enormous energy saving only becomes truly clear in a direct comparison between conventional ventilation systems and radiant systems.

Radiant panels arranged evenly across the ceiling create a perfect, naturally comfortable climate. The heat is evenly distributed across the entire surface.

Principles of Radiant Heating

The most important consideration when choosing a heating and cooling system is energy efficiency. Zehnder radiant heating and cooling systems can save more than 40% in energy compared to other systems. And all with a pleasant indoor climate.

The following visuals compare the energy levels of radiant systems and air heating systems.

With Zehnder ZBN radiant panels, you can achieve energy savings of over 40% through efficient heating and cooling of buildings compared with other methods of heating buildings.

Zehnder radiant ceiling panels work on a fundamental natural principle that is identical to the way in which the sun produces warmth.
We spend almost three quarters of our lives indoors: at home, at work, during our leisure time. The indoor climate (temperature and air quality) is itself a big influence on our general wellbeing.
