In an era where thermal comfort has become paramount, low-profile underfloor heating renovation presents itself as an innovative solution to optimize space and improve the well-being of occupants. By 2025, technological advances in this field are such that they meet the varied needs of renovation projects while ensuring easy and quick installation. Discover how these high-performance systems can transform your interior, combining comfort and energy efficiency.

The fundamentals of modern underfloor heating

In today’s heating solution landscape, underfloor heating has established itself as a must-have for both new buildings and renovations. Thanks to innovations such as the RAUTHERM SPEED RENOVA concept, it is now possible to install a heating system while respecting height constraints. Indeed, this technology allows the integration of an underfloor heating system with a thickness of only 24 mm, including the screed, greatly simplifying the task during property renovations.

Why choose a low-profile underfloor heating?

  • Space-saving: This type of system requires less reserved height, allowing for a higher ceiling or simply gaining more living space.

  • Reduced weight: Weight constraints are no longer an obstacle, making it ideal for various types of housing.

  • Ease of installation: Direct installation on an existing floor such as tiles or raw concrete speeds up the renovation process.

With increasing requirements for comfort and efficiency, these low-profile heating systems are multiplying. Not only do they ensure comfortable warmth, but they also optimize energy consumption. As I often emphasize to my clients, a well-thought-out installation can have a lasting impact on your quality of life.

The key components of the RAUTHERM SPEED RENOVA system

Each underfloor heating system relies on specific components that guarantee optimal performance. The RAUTHERM SPEED RENOVA system primarily consists of:

  • RAUTHERM SPEED RENOVA panels: Designed for quick fastening, they feature a self-adhesive surface.

  • RAUTHERM SPEED pipes: With a diameter of 12 mm, these Pe-Xa pipes allow for effective heating with simplified installation.

  • Thermio+ SA® R+R® screed: Its anhydrite composition ensures high thermal conductivity (2.2 W/m.K) and rapid responsiveness.

This combination of technologies not only ensures unparalleled heating comfort, but also facilitates integration into homes that are already insulated or need insulation. As a professional who values innovation, I am convinced that these systems represent the future of heating renovation.

The advantages of using fluid screeds

The fluid screed used in the system is specially designed to interact with heating elements. With its reduced thickness of only 10 mm above the pipe, it is extremely effective at transferring heat. This feature is essential as it allows reaching a desired ambient temperature faster, thus reducing the operating time of the installation.
In other words, less energy consumption means substantial savings on your bills. By choosing a more transparent and connected approach, it is possible to increase your energy efficiency.

Connected regulation for optimized heat management

With the integration of the NEA SMART 2.0 thermostat regulation, you can now manage the temperature of each room independently. This connected aspect of heating offers unprecedented flexibility. Imagine being able to adjust the heat in your living room, bedroom, and even office at different times, all with a few clicks on your smartphone.
With its EU.BAC certification and a responsiveness of 0.3 K, this system can save you up to 25% on your heating bill.

Why is thermal regulation essential?

  • Adaptability: Meet your variable heating needs according to the seasons.

  • Energy savings: Your primary energy consumption is optimized.

  • Personalized comfort: Adjust each room according to your preferences, without delays.

As a plumber passionate about my clients' comfort, I see this connected aspect as a real asset in managing modern living spaces. It is a step towards the future and eco-friendly renovation of your home.
