When we consider a renovation project or the construction of a new house or flat, we consider various heating solutions and radiant heating is one of the most sought-after, both for its comfort at all times of the year, although it is in autumn/winter that it stands out the most, and for its energy efficiency.
If you're considering investing in underfloor heating, it's important to know whether it's compatible with floating floors, be they laminate, vinyl, parquet or cork. The good news is that it is possible to combine these two solutions to create a cosy and comfortable environment in your home.
Radiant Heating: The Technology Behind Thermal Comfort
Radiant heating is a technology that differs from traditional convection heating systems. Instead of heating the air surrounding the space, radiant heating emits heat directly from the floor, radiating upwards and warming objects and people in the room. This method creates a unique feeling of comfort and eliminates the need for radiators or noisy fans.
Underfloor heating systems generally consist of electric cables or hot water pipes embedded in the floor. They distribute heat evenly, eliminating cold spots and providing a soft, pleasant warm feeling throughout the space. In addition, radiant heating is highly energy efficient by reducing heat loss and allowing better control of room temperature.
Compatibility with floating floors
The answer to the question of whether floating floors are compatible with underfloor heating is yes. It is possible to install laminate, vinyl, parquet or cork flooring over an underfloor heating system, be it hydraulic or electric. The main difference between these floors lies in their thermal resistance, with vinyl floors having a slightly lower resistance rate, which means they heat up more quickly than the others. Each type of flooring has its own specific characteristics, along with standards for installation and use in underfloor heating systems.
Underfloor Heating Systems: Hydraulic and Electric
There are two common options for radiant heating systems: hydronic and electric. The hydraulic system involves installing a network of pipes through which water circulates to heat and cool surfaces. This installation is more suitable for new constructions or renovations, as it requires the pipes to be incorporated into the floor screed. In the long term, hydraulics can be more economical, especially if the water is heated by renewable energy sources.
On the other hand, the electrical system is more affordable in terms of initial costs, since it doesn't require special infrastructure such as boilers or heat pumps. It is especially suitable for renovations, as it does not require raising the existing floor. However, it can be more expensive in the long term, depending on energy consumption. The great advantage of this system is its rapid temperature regulation and simplified maintenance.
Essential Care for Floating Floors in Heating Systems
When installing a floor over an underfloor heating system, it is essential to follow the specific regulations for each type of floor and ensure compatibility with the heating systems. Make sure you use the accessories recommended by the manufacturers to optimise the performance of the heating system and protect the floor from possible damage.
In addition, some general observations must be observed in radiant heating systems:
- The maximum temperature on the floor surface must not exceed 27ºC;
- Always adjust the temperature gradually at the beginning and end of the heating period to avoid damaging the floor;
- Daily temperature variations are acceptable, as long as the maximum floor temperature remains within limits;
- Keep the relative humidity within the limits recommended in the installation instructions;
- Avoid heat build-up under carpets, rugs or furniture close to the floor;
- During the heating period, openings can occur in the floor joints.
Importance of Thermal Resistance and Insulation
Each type of floor has a different thermal resistance, and thicker floors, such as wooden floors over 18mm thick, can slow down the passage of heat. To optimise the heating system, it is advisable to apply an insulating layer under the heating system. This allows the heat to be reflected by the insulating layer and directed through the floor more efficiently.
