Zehnder heating and cooling ceilings efficiently heat and cool large spaces such as offices, or industrial and sports halls from the ceiling and ensure an unobstructed view of the architectural design. They create a pleasant indoor climate all year round with extremely energy-efficient operation.
The system is designed according to the latest state of the art. You have a free choice of energy source and can optimally combine the heating and cooling ceiling with renewable energies or a heat pump. Save up to 40% energy this way.
The even and pleasant temperature distribution in the room, without draughts or unpleasant temperature fluctuations, is extremely pleasant. The result is a comfortable indoor climate in which you feel good all around.
Whether it's a new build or a retrofit project - the heating and cooling ceiling can be installed quickly and easily in any room from 2 m to 50 m high. In addition, the installation on the ceiling keeps the view free for the architectural design of the room.
Are you wondering how heating from the ceiling works when warm air does rise? And how do cooling ceiling systems work that are also energy-efficient? Learn more in our explanatory video.

Instead of heating the room air directly, the ceiling heating or radiant ceiling panel uses the principle of radiant heat. This principle is comparable to the warmth of the sun's rays on a cold winter day. For heating, the electric blanket emits the heat energy as infrared radiation, which hits the surfaces and objects in the room and warms them.
The cooling ceiling absorbs the heat energy in the room and transfers it to the water-carrying pipe system that runs in the chilled ceiling system. The cool water extracts the heat from the surfaces and objects in the room, creating a pleasant coolness and an optimal climate.
Unlike air conditioning, ceiling systems do not use environmentally harmful refrigerant. A cooling ceiling uses water that flows through the pipes. Cooling systems, like an air conditioner, have a lot of air movement, which is often perceived as uncomfortable. In addition, an air conditioner is mounted on the wall, taking up valuable space. Ceiling systems for heating and cooling are also much more energy efficient than an air conditioner.
Yes, the systems fit together perfectly. A heating and cooling ceiling can be operated with a heat pump by using the heat pump as part of a water-based heating system. The flow temperatures are very low and are 45 - 60°C, as compared to underfloor heating. We will be happy to advise you on the optimal design for efficient heat transfer.
In contrast to air heaters, gas radiators, underfloor heating or air conditioning, heated and chilled ceilings save up to 40% energy. In addition, there is no noticeable convection. The floor and walls are free of radiators or air conditioners, which offers new design possibilities.
Heating and cooling ceilings are available in open and closed versions. Therefore, there are many variants for integrating all kinds of other functional elements. Lamps, for example, can be integrated into cut-outs or mounted between or below the ceiling panels. Sprinklers, loudspeakers, air outlets, etc. are also placed in cut-outs.
Condensate forms from the interaction of temperature and humidity. Chilled ceilings are therefore operated as a surface system with low sub-temperatures (difference to room temperature). This already limits the area in which condensate can form. The rest is taken care of by the system control, for example with temperature and humidity sensors.
