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.
