What can AQUATHERM BLACK do?
aquatherm black is a multi-award-winning surface heating and cooling system. Versatile in use, manufactured in a compact register design, and equipped with a future-proof technology - these are some of the essential features of aquatherm black. The special feature: It can be installed in the ceiling as well as in the wall and the floor. Depending on the requirements, the surface temperature of the elements is driven a few degrees above or below the desired room temperature. The radiant energy provides either pleasant warmth or cooling without disturbing draughts or dust turbulence.
aquatherm black is energy-saving thanks to perfect control technology. The system is ideal for use with low-temperature systems such as heat pumps. Building owners and architects can enjoy the flexible application areas and the associated design freedom. Whether as a cooling ceiling in the office, as wall heating in the bathroom, or as underfloor heating in a renovated old building - the possibilities are almost unlimited. Finally, the panel heating and cooling elements can be installed in drywall construction, in plastered ceilings, walls, or in suspended coffered ceilings and are invisible afterwards.
Surface heating and cooling system for ceilings, walls and floors

The assembly of the aquatherm black energy grids is simple: just between the supporting profiles of the metal substructure. Then the ceiling is covered with building boards. For this, e.g. buildings boards with made of plasterboard with different thermal conductivities can be used. The aquatherm black energy grids are available in different widths and lengths so that the ceiling can be individually covered.

Sound absorption
Sound absorption describes the reduction of sound energy. By reflection of the waves at the room boundaries a diffuse sound field is created, in which the direct sound of the sound source is superimposed with reflecting sound components and effects from all directions with approximately the same intensity. If it is possible to reduce the reflections at the room boundaries, it gets quieter in the room. The absorption coefficient a indicates how large the absorbed part of the total incident sound is:
- If a = 1, the entire incident sound is absorbed, there is no longer any reflection.
- If a = 0.5, 50% of the sound energy is absorbed and 50% of the sound energy is reflected.

With its impressive underfloor heating, aquatherm black provides an even surface heat which prevents the growth of dust mites and the formation of mould. Whether its open screed in workshops, production halls or garages, tiles, or parquet and laminate in apartments and houses, the floor construction can be individually and diversely executed.
Convection versus radiant heat
Radiant heat and convection heat are two different methods of heating a building. Radiant heat uses radiant energy to directly heat objects and people, while convection heat heats the air in a room, which then circulates and heats the room. Radiant heat offers several advantages over convection heat in terms of energy efficiency and comfort.
Advantages of radiant heat
Radiant heat is generally more energy efficient than convection heat because it heats objects and people directly instead of heating the air. Consequently, less energy is required to maintain the desired temperature in a room and there is less heat loss through windows, walls and ceilings.
Radiant heat provides a more even and comfortable heat distribution than convection heat. This is because radiant heat warms objects and people, which then radiate heat back into the room, creating a more even and comfortable temperature. With convection heat, the warm air rises to the ceiling, so the lower part of the room is colder and there are thermal and cold bridges.
Radiant heat is also healthier than convection heat because it does not dry out the air or create air currents that can spread dust and allergens. This is especially important for people with allergies or respiratory diseases.
Radiant heating systems are generally quieter than convection heating systems. Noise can occur with convection heating systems when the air circulates, especially in systems with forced ventilation.
Radiant heating systems can be designed to be more aesthetically pleasing than convection heating systems. Radiant heat can be integrated into floors, walls or ceilings, giving architects and interior designers more design options.
What should you know about the technical features of AQUATHERM BLACK?

The aquatherm black heating/cooling registers are installed between the supporting profiles of the substructure. Then the ceiling is covered with plasterboard. Large areas in office and administration buildings, or even entrance and event halls can therefore be heated and cooled over a large area with aquatherm black. Whether it is a large project or a single-family house, retrofitting during renovation or maintenance work can be done quickly, easily and cleanly. The low installation height reduces the room height only minimally and creates more usable living space by eliminating radiators.

The registers for heating and cooling are installed in the stud frame of a drywall and then covered with plasterboard. One area of application is, for example, installation in renovation measures where it is no longer possible to lay the registers in the floor or ceiling, or in retrofitted walls to separate rooms.

aquatherm black is exclusively made of fusiolen® PP-R. This material is characterised by its special high heat and extraction stability. The physical properties are adapted to the special requirements of the heating and cooling sector.
The exceptionally good welding properties and the fusion into a homogeneous and materially cohesive unit offer maximum safety and durability. Fusiolen® PP-R is also characterised by high temperature and pressure resistance.
Continuous temperatures of 70 °C can be operated without any problems. As a rule, the aquatherm black system is operated with considerably lower flow temperatures than usual underfloor heating systems.
The actual material stress is therefore lower. Furthermore, fusiolen® offers excellent resistance to a wide range of aggressive chemicals.
In connection with the aquatherm blue pipe (also made of fusiolen® PP-R) for air-conditioning, heating and plant engineering, aquatherm offers a complete solution from the heat or cooling generator.
Questions that customers often ask about AQUATHERM BLACK
Plug-in/clamp connection
Our innovative system uses a smart „plug-in/clamp connection“, to connect the energy grids quickly and reliably with each other. Thanks to a flexible and bendable connection tube, with spring band clamps, installation is simple. Attach the end of the pipe to the connection piece and push it with light pressure until it stops. Then push the spring band clamp to the second stop of the connector and release the pre-tension. Our system offers not only the highest functionality but also easy handling. The plug-in clamp connection is mechanically detachable. You can use commercially available hand pliers for spring band clamps to remove the connection effortlessly
Welding
The aquatherm black is connected by means of “heating element socket welding”. By heating the connecting parts, the plastic melts to form a materially bonded and inseparable connection. The individual registers can be connected directly in parallel on one side, or alternately on the other. With the extensive aquatherm moulding range, single connections as well as large systems can be completely constructed, including distribution technology.
The idea behind aquatherm black is the well-being of the room users: to create a thermally balanced room. The principle of the aquatherm black technology is therefore not to heat and circulate air, but rather to radiate heat from the tempered walls or ceilings directly to the room or the person. A comfortable warmth, as the heating surface temperature can be selected low due to the relatively large heating surfaces. This is an advantage compared to small, hot surfaces such as radiators or convectors.
Due to the lower flow temperature (25-35 °C), the systems are excellently suited in combination with heat generation at a similarly lower temperature level. This opens up a wide range of possibilities for using condensing technology and alternative energies, such as solar, geothermal and waste heat. Another thermally based advantage is the lower air movement. The result is less turbulence of house dust and homogenous humidity. Overall, the wall or ceiling heating saves 25-30% of energy costs and makes an important contribution to a healthy indoor climate and to maintaining the value of the building. The aquatherm black for wall and ceiling can be combined.
Comfort
Moderate excess temperatures (25-35 °C) with large heating surfaces create an even radiation balance for the user. Direct heat radiation on the human body is perceived as thermal comfort. The air temperature can be lower compared to conventional heating techniques (radiators/convectors) and still maintain thermal comfort for the room user.
