Watercooled Ceiling - Silent, Natural, Energy-efficient

Radiant cooling ceilings provide a perfect indoor temperature all year round. During the summer period the cooling power insures a pleasant indoor climate without adverse effects of an air condition like cold air circulation and high energy consumption. During the cold period the function as heating ceiling guarantees a uniform and pleasant warmth.

The installation of a radiant cooling and radiant heating in one system reduces investments and operating costs. Heating without radiators opens a space for modern interior architecture.

Benefits of Radiant Ceiling Cooling and Heating

  • Heating and Cooling with one single system
  • Modelled on Nature
  • Directly perceived, pleasant heat
  • Low air circulation
  • Healthy indoor climate with significant less allergenic impact
  • Low energy consumption costs

Warm Feet - Because the Ceiling Heat Radiates

Learning from Nature

The heat from the sun has a very pleasant and direct effect on cool days. Ceiling heating also radiates from above with mild temperatures on residents and room interior alike. All objects in the room and all room enclosing surfaces are heated by the radiant heat from the ceiling heating. Since the floor is thermally insulated, the radiant heat from the ceiling is absorbed there, resulting in a floor surface that is slightly warmer than the indoor temperature. There is no need to worry about cold feet with a radiant ceiling heating.

Since the surface temperature of the ceiling is not significantly higher than the temperature in the room, the air circulation by thermal flow is also insignificant. The room is not heated by warm air rising but almost exclusively by radiant heat.

Radiant Cooling Ceilings – Cooling without a Cold

Radiant cooling ceilings create a high degree of thermal comfort. Cooling without annoying air circulation contributes to the high acceptance and satisfaction especially amongst allergy sufferers. This is why more and more hospitals invest in radiant cooling ceilings.

„From a medical point of view, we consider it very important for our patients to have draught-free, uniform thermal room conditioning.”
Thomas Höhn, Administrative Director, German Heart Centre, Berlin (DHZB)

The risk of condensation on the cooled ceiling is reliably and safely prevented by limiting the supply temperature and by conditioning fresh air supply.

Since the perceived room temperature under cooling ceilings is slightly below the actual room temperature. This has additional positive effects on energy consumption for cooling.

Types of Cooling Ceilings Systems

3 different types of ceiling heating and cooling systems from the BEKA production:

  • Capillary tube mats for thermally activating plaster, metal acoustic or plasterboard ceilings
  • Serpentine copper tubing for metal acoustic or drywall ceilings
  • Single pipe technology for plasterboard or plaster ceilings

Radiant Ceiling Heating & Cooling for Single Family Homes


Energy-efficient radiant heating and low-cost construction are not a contradiction in terms. This can be experienced at the model house constructed by Bau- und Ausbau GmbH in Berlin Staaken. Comfort is provided by ceiling heating and cooling in combination with a heat pump and a photovoltaic system for single-family homes.
