Why install underfloor heating?
Underfloor heating is no longer reserved for high-end new homes. Thanks to advancements in technology, it is now perfectly compatible with renovations, provided it is well planned.
A gentle and even warmth
The system operates at low temperature, allowing for a uniform distribution of heat throughout the room. The result: no cold spots, no drafts, a constant and pleasant temperature, both for the feet and for the overall ambiance.
A space-saving solution and perfect aesthetics
With the heating integrated into the floor, you save space and avoid the visual clutter of radiators. This allows for total freedom in the layout of your rooms, and a clean aesthetic, appreciated in contemporary interiors.
Better energy efficiency
Operating at a water temperature between 30 and 45 °C, underfloor heating consumes less energy than a radiator system, especially when paired with a condensing boiler or a heat pump. It is perfectly suited to the requirements of low-energy renovations.
The different types of underfloor heating
There are two main families of underfloor heating, each with its specificities. The choice depends on your heat production system, the configuration of your floor, and the level of performance sought.
Installation techniques and site configuration
The type of installation depends on the configuration of your floor and the nature of the work (new or renovation).
- Embedded installation in a screed: standard in new construction or heavy renovation
- Thin installation in renovation: ideal for preserving ceiling height in existing homes
- Installation on thermal insulation: improves efficiency by limiting downward losses
- Possibility of room-by-room regulation with individual thermostats
Our technicians assess your configuration and offer you the solution best suited to your home.
What is the price of underfloor heating in Belgium?
The price varies according to the type of system, the area to be covered, the type of existing floor, and the desired finishes.
Factors to consider
- Nature of the floor (new, existing screed, leveling...)
- Type of system (hydronic or electric)
- Additional work: removal of existing covering, creation of screed, leveling
- Room-by-room regulation
- Coupling to a boiler or heat pump

FAQ – Underfloor Heating and Energy Renovation in Belgium
Is underfloor heating suitable for an energy renovation?
Yes, absolutely. The low-temperature underfloor heating is one of the most efficient emitters in an energy renovation project. It consumes less energy than a traditional radiator system, distributes a gentle and uniform heat, and allows for optimizing the efficiency of a condensing boiler or heat pump. It is particularly effective in well-insulated homes.
Can underfloor heating be installed in an old house?
Yes, under certain conditions. There are thin underfloor heating systems specifically designed for renovations. They require little thickness (often less than 5 cm) and can be easily installed over an existing floor. A prior technical study allows for checking the compatibility of the substrate, the available height, and the appropriate type of flooring.
Does underfloor heating qualify for an energy grant?
Yes, if it is integrated into a comprehensive energy renovation project. In Belgium, the Regions offer conditional grants:
- for the installation of a high-performance system (low temperature)
- for the replacement of the heat generator
- for conducting an energy audit or PEB
The programs include:
- Habitation Grant (Wallonia)
- Renolution (Brussels)
- Mijn Verbouwpremie (Flanders)
Our experts will assist you in maximizing this installation in your grant application.
Hydraulic or electric underfloor heating: which one to choose?
- The hydraulic underfloor heating is the most common in energy renovations. It is economical to use and compatible with high-performance boilers or heat pumps. Ideal for large areas.
- The electric underfloor heating is easier to install but less cost-effective in the long run. It is recommended for supplementary heating or for small rooms like bathrooms.
The choice depends on the type of energy, the budget, and the overall project.
Can the temperature be regulated room by room with underfloor heating?
Yes. It is highly recommended to install independent zone or room regulation. This allows for programming the temperature according to needs, reducing consumption, and improving overall comfort. Many systems are compatible with home automation and remote control via smartphone.
