The construction industry, architects, planners, and installers are faced with the major task of renovating existing buildings to make them more energy-efficient in order to implement climate protection goals, sustainability and the energy transition. This also largely applies to the heating systems. Heat pumps only achieve their highest efficiency when they are operated in combination with surface heating systems. Here, ceiling heating comes into focus as an economical and intelligent solution.
Ceiling heating, such as the aquatherm black system, offers a less intrusive option to more significant restoration work. Instead of major interventions in the building fabric, it enables rapid and cost-effective modernisation – even when inhabited. In this blog, we shed light on why aquatherm black is a forward-looking answer to the challenges of energy-efficient renovation, what opportunities are available to you and how you can contribute to effectively meeting the sustainability goals.
Choosing the right heating system is crucial when it comes to the energy-efficient renovation of existing buildings. In this case, the aquatherm black system is an ideal solution for ceiling heating . The adaptability of aquatherm black to existing structures enables a less invasive installation that eliminates the need for major structural interventions. Renovation can be carried out according to the "room to room" principle. As a result, buildings can continue to be used or inhabited almost without restriction.
Another important aspect is energy saving through efficient heat transfer. aquatherm black offers high energy efficiency with flow temperatures between 25°C and 35°C. By way of comparison, conventional heating systems often require flow temperatures of around 70°C. In addition, ceiling heating systems are characterised by a high radiation efficiency of up to 92%, significantly more than wall heating with 69% and underfloor heating with 50%.
The flexibility of aquatherm is particularly evident in the simple connection to various heating sources. For example, the surface heating system can be installed in the ceiling first and then later switched to a new heating technology using renewable energies, such as a heat pump. This adaptability gives builders and investors more freedom in scheduling renovation projects.
Another advantage of aquatherm black is that it is quick and easy to install, even when it is in use or inhabited. This is supported by the new plug-and-clamp connections, which enable even more efficient and reliable installation of the coils. Installation requires less effort and saves significant time during renovation. Instead of using plug-and-clamp connections, another option is to implement welded connections.
As a planner, installer or architect, you are faced with the question of how to optimally integrate surface heating into the existing rooms when it comes to existing buildings. To this end, aquatherm offers various solutions for ceiling installations that can be adapted to the specific requirements and circumstances:
The installation of the aquatherm black energy coils in drywall construction with metal substructure is uncomplicated and efficient. Embedded between the support profiles, this system enables flexible adaptation to room conditions by means of individually selectable register sizes.

Thanks to the dry construction method, you benefit from rapid construction progress and creative freedom in ceiling design.
The aquatherm black grids are mounted between the supporting surface and the wooden substructure. Subsequently, the wall or ceiling is covered with building boards, for example made of plasterboard. Due to the different grid widths and lengths, the ceiling surface can be individually equipped, which creates additional scope for ceiling installations such as spotlights, suspensions for lighting and smoke detectors.
In addition to the high heating and cooling performance due to the full-surface activation of the ceiling surfaces, this system offers quick and easy installation. It is ideally suited for the use of heat pump and condensing boiler technology due to its ability to use low supply and return temperatures.
Power is delivered without draughts, and the system reacts quickly to temperature changes. Thanks to the dry construction method, you benefit from rapid construction progress and at the same time have creative freedom in the ceiling design.
The installation of the aquatherm black energy grids in a drywall system with insert plates is characterised by its simplicity and speed. The grids are placed on metal inserts and securely fastened with hold-down magnets, which ensures efficient heat transfer through direct contact.
This installation allows for high heating and cooling capacities, as the grids offer optimal heat transfer through direct contact with the metal inserts. Thanks to the factory-prefabricated modules, quick assembly on site is guaranteed. In addition, low supply and return temperatures can be achieved, which is particularly advantageous for the use of heat pumps and condensing boiler technology.
The system can be easily integrated into existing ceiling systems and offers high sound absorption, especially for ceiling tiles with perforations and acoustic fleece. It is also compatible with various built-in ceilings such as lighting, fire detectors and ventilation components, allowing for extensive use of the ceiling surface.
The plastered solution offers an elegant and invisible way of installing surface heating. In this method, the custom-made aquatherm black grids are mounted directly on the raw ceiling and then completely embedded in a layer of plaster.
After attaching the grids and the connection piping to the wall, the plaster is applied, using all common types of plaster such as gypsum, lime, cement or clay.
This technology enables high heating and cooling capacities due to the full-surface activation of the ceiling surfaces. In addition, it ensures a silent and draught-free heating and cooling function, which contributes to a particularly pleasant indoor climate. The plastered solution is suitable for almost all ceiling surfaces and is characterised by its small space requirement.
