aquatherm black system is a versatile, multi-award-winning surface heating and cooling system. It can be installed in the ceiling as well as in the wall or floor. Depending on an application’s requirements, the surface temperature of the aquatherm black system elements can be set a few degrees above or below the desired room temperature. The radiant energy delivers either a comfortable warmth or cooling without creating drafts or raising dust.

aquatherm black system offers energy-savings thanks to advanced control technology. The system is ideal for use with low-temperature systems such as heat pumps. Builders and architects can look forward to application flexibility and the associated design freedom: whether providing ceiling cooling in the office, wall heating in the bathroom, or underfloor heating in a renovated building, the possibilities are almost limitless. The surface heating and cooling elements, which are made of corrosion-resistant polypropylene, can be installed in drywall, in plastered ceilings, walls, or suspended coffered ceilings, and are invisible once deployed.

1. Ceiling system with metal substructure
The aquatherm black system heating/cooling grids are installed between the supporting profiles of the substructure. The ceiling is then boarded with plasterboard panels. Large areas in office and administration buildings as well as entrance and event halls can be heated and cooled with aquatherm black system. No matter if a large-scale project or a single-family house, the retrofit installation during renovation or maintenance is fast, easy and clean. The low construction height reduces the room height only minimally and creates more usable living space by the omission of radiators.

2. Metal ceiling panel
The grids for heating and cooling are placed in the metal panels. The contact of the grids with the panels ensures excellent power transfer. In offices or practices aquatherm black system provides draught-free cooling in the summer and pleasant warmth on cold days.

3. Wall system with metal stud wall
The heating and cooling grids are installed in the drywall stud frame and then boarded with plasterboard panels. Applications are e.g., renovation measures in which a laying in the floor or ceiling is no longer possible or retrofitted walls for room partitioning.

4. Plastered wall and ceiling heating
The grids for heating and cooling are integrated right under the bare ceiling into the plaster layer. The grids and connected piping are attached to the ceiling. Plaster works are done according to general plastering guidelines. All commercially available gypsum, lime, cement and loamy clay are suited for it. The low installation height of the aquatherm black system and the loss-free heat emission through the enclosing material are perfect for generating natural and healthy heat.

5. Ceiling system with wooden substructure
The aquatherm black system heating/cooling grids are installed between the supporting profiles of the substructure. The ceiling is then boarded with plasterboard panels. Plasterboard of different thermal conductivities can be used. With an insulation carried out according to EnEV, aquatherm black system presents its advantages in new buildings and in housing extension. The radiant heat can be used optimally with a low flow temperature. Heat accumulation in the gable area belongs to the past.

6. Use in the shower area
aquatherm black system grids provide cosy warmth in the shower area. Cold radiating tiles along with mould formation belong to the past. The individual adaptability to the shower size and the shower fitting enables installation in both new and old buildings. aquatherm black system can be connected and combined with the existing heating appliance or underfloor heating system.

7. Mirror heating and towel warmer
aquatherm black system installed behind a mirror prevents the mirror from fogging. Easy installation and different available sizes make it the ideal complement to the wall heating in the shower. aquatherm black system grids are also well suited as invisible towel warmers providing additional comfort.

8. Underfloor heating
aquatherm black system also scores as underfloor heating. There is no dust swirling-up as usual with radiators. The uniform surface heat prevents the growth of house dust mites and mould fungus formation. Whether open screed in workshops, production halls or garages, tiles, parquet and laminate in apartments and houses, the floor construction can be carried out individually and varied.

  • high comfort due to radiant heat
  • no drafts
  • energy saving in operation
  • versatile
  • architectural freedom of design
  • fast installation

The basic idea of the aquatherm black system is creating a thermally balanced space that enhances the well-being of the occupants.
aquatherm black system technology is therefore not focused on air heating and circulation, but rather heat radiation from tempered walls or ceilings directly into the room and onto its occupants. The black system’s relatively large heating surfaces allow the temperature of the heating surface to be set low, which provides a soothing warmth. This is an advantage compared to small, hot surface areas such as those found in radiators or convectors.

Due to the lower flow temperature (25 to 35°C), the black system is ideally suited to work in combination with systems that generate heat at lower temperature levels, such as condensing technologies and alternative energy sources.

Another advantage is reduced air movement. This reduces dust turbulence and creates a uniform humidity.

Radiant wall/ceiling heating can save 25 to 30 percent in energy costs and makes an important contribution to a healthy indoor climate and the value of the building.

Comfort benefits

Moderate temperature setpoints (25 to 35°C) with large heating surfaces produce a uniform radiant balance. The direct heat radiation presents the human body with a comfortable, cosy warmth. The air temperature may be set lower compared to conventional heating techniques (such as radiators or convectors) yet still provide exceptional thermal comfort for the occupant.

Our material fusiolen® PP-R

aquatherm black system is exclusively made from fusiolen® PP-R. The physical properties specially match the requirements of the heating and cooling sector.

The exceptionally good welding properties offer a maximum in security and durability. fusiolen® PP-R also provides high temperature and pressure resistance.

A permanent operating temperature of 70 °C is no problem. Normally, the aquatherm black system operates at substantially lower temperatures than conventional heating systems.

In conjunction with the aquatherm blue pipe system (also made from fusiolen® PP-R) for climate, heating and industrial technology, aquatherm offers a complete solution for heating and cooling generators.

Connection technology part 1: Fusion

aquatherm black system grids are reconnected to each other by heating element socket welding. By heating the connection parts, the plastic merges into a cohesive and permanent connection. With the comprehensive range of aquatherm green pipe fittings, both individual connections and complete large systems can be built including distribution technology. Transition connectors to the proven aquatherm grey pipe sliding sleeve technology as well as to the aquatherm orange system and a 15 mm press connection complete the system.


Connecting technology Part 2: Push-fit connection

aquatherm black system grids are simply and securely connected in suspended ceilings by using push-fit connectors. The grids are provided with 16 mm plug-in connections, on which the push-fit connector only must be inserted as far as possible. The holding ring is equipped with stainless steel teeth, keeping the connector firmly in the joint. The two integrated O-rings provide a completely sealed and secure connection. The holding ring and the O-ring are held in place by a brass locking ring.

NEW: High-performance modules for cooling ceilings

The surface temperature of aquatherm black system high-performance modules is only a few degrees above or below the desired room temperature. Thus, the modules are ideal for heating systems using renewable energies, such as heat pumps. The uniform heat or cold transmission by means of radiation ensures increased comfort. In addition, there are no draughts created or dust raised, as can be the case with blower-driven heating and cooling systems.

  • high heating and cooling performance due to excellent transmission surface contact
  • short assembly times thanks to pre-fabricated, self-adhesive modules
  • soundless and invisible
  • no draughts or airborne dust blowing around
  • ideally suited for use with heat pump and condensing boiler technology due to low flow and return temperatures
  • high sound absorption in metal ceiling panels with micro perforation or in perforated plasterboard plates
  • retrofittable into existing metal ceiling systems
