Underfloor heating: how it works and the benefits it brings to your home

An efficient, invisible, and comfortable heating solution that redefines home wellbeing. Discover everything you need to know about underfloor heating in this article.

More and more interior design projects are turning to sustainable and discreet climate control systems. Underfloor heating has become one of the most efficient and aesthetically pleasing options on the market, offering even thermal comfort and significant energy savings without altering the interior design of the space.

What Is Underfloor Heating and How Does It Work?

Underfloor heating is a system that provides heating —and in some cases, cooling— by distributing heat evenly through the floor of a home.
Unlike traditional radiators that emit hot air, this system warms the surface from below, creating a more pleasant and consistent temperature throughout the room.

It works through a network of pipes or electric cables installed beneath the flooring, which transmit low-temperature heat. This allows the system to maintain a comfortable environment while using far less energy than conventional solutions.

Advantages of Underfloor Heating

1. Consistent Thermal Comfort

The heat is distributed evenly across the entire room, with no air drafts or temperature fluctuations. The result is a uniform sense of comfort in every corner of the home.

2. Energy Efficiency

Underfloor heating operates at much lower water temperatures than traditional systems, resulting in energy savings of up to 20–30%. When combined with renewable technologies such as aerothermal energy, its efficiency and sustainability increase even further.

3. Aesthetic Freedom

Because it’s completely integrated beneath the floor, underfloor heating removes the need for visible radiators or vents, allowing for a cleaner, more harmonious, and flexible interior design.

4. Quiet and Healthy

This system produces no noise and doesn’t stir up dust, improving indoor air quality and offering a healthier and more serene home environment.

5. Year-Round Comfort

The most advanced systems can also provide cooling in summer, offering a complete climate solution for all four seasons.

Types of underfloor heating

· Hydronic (Water-Based) System

This system uses hot water that circulates through pipes installed under the floor. It’s the most efficient and sustainable option, especially when paired with renewable energy systems like aerothermal heating.

· Electric System

This alternative uses electric cables or mesh to heat the floor directly. It’s easier and more affordable to install, although energy consumption can be slightly higher.

Installation and Maintenance

Underfloor heating requires careful planning from the beginning of a renovation or construction project, as it involves lifting the existing floor.
In return, it offers almost zero maintenance and long-lasting performance, making it a smart investment for new homes or full-scale renovations.

Why Install Underfloor Heating at Home?

Although the initial cost is higher than conventional systems, the comfort, efficiency, and sustainability benefits far outweigh the investment in the medium and long term.
Its seamless integration also makes it the perfect ally for contemporary interior design projects, where aesthetics and functionality go hand in hand — as seen in our Andrea Apartment project.
