What is the installation cost of underfloor heating in renovation?

In the modern world, thermal comfort has become a priority for many households. One of the most innovative and effective solutions to achieve this is the underfloor heating. By integrating this system under the floor, you benefit from a homogeneous and constant diffusion of heat. If you are considering its implementation as part of a renovation, it is essential to have a precise idea of the associated costs, as these can vary significantly depending on several criteria. This article guides you in evaluating the installation cost of underfloor heating, focusing on the different types, materials used, and considerations related to labor costs.

Understanding how underfloor heating works

Underfloor heating is a modern heating system that stands out for its efficiency and aesthetic appeal. Unlike traditional radiators, it is discreet and elegantly integrated into your interior decor. The operation relies on two main types of systems: electric and hydraulic.

What is underfloor heating?

Underfloor heating systems operate by using either electric resistors or hot water circulating through pipes. The heat is then evenly distributed throughout the room. This system offers several advantages:

• Optimal thermal comfort thanks to a gentle floor temperature.

• Energy savings: operating temperatures are generally lower.

• Aesthetic: freeing up floor space by avoiding radiators.

There are three main types of underfloor heating:

• Hydraulic: uses heated water circulating in circuits beneath the floor.

• Electric: uses heating cables integrated into the floor.

• Reversible: serves both heating and cooling purposes.

Cost of installing underfloor heating

The cost is one of the main factors to consider before installing underfloor heating. Several elements influence the price, including the type of flooring, the area to be covered, the choice of materials, and labor costs. Generally, the price per square meter can vary from €40 to €350, depending on the specifics of the installation.

The price of electric underfloor heating

Electric underfloor heating systems are often chosen for their quick installation and efficiency. Their price generally ranges from €40 to €350 per m², including installation. The key element here is the electric resistance, for which it is essential to choose quality models, as this will impact the durability and efficiency of the system.

The price of hydraulic underfloor heating

Hydraulic underfloor heating systems are based on the principle of water radiators and are often considered more economical in the long term. Their initial cost ranges between €50 and €150 per m², excluding the price of the boiler or heat pump. This system has the advantage of being compatible with various heating sources, including solar energy. In summer, it can also serve as a cooling system.

The price of reversible underfloor heating

Reversible underfloor heating stands out for its ability to produce both heat in winter and coolness in summer. It often requires a reversible heat pump. The average price ranges between €100 and €120 per m². Although it represents a higher investment, its energy performance and flexibility make it a sustainable choice in the long run.

Additional costs related to installation

In addition to the cost of materials, it is crucial to take into account the cost of labor. The installation of underfloor heating requires specific skills and must be carried out by a qualified professional to ensure the safety and efficiency of the system.

Labor costs

The rate for installing underfloor heating varies between €40 and €60 per hour, depending on the region and the craftsman's experience. This rate may increase if additional work is required, such as leveling or structural modifications. The labor includes several essential steps:

• Checking the existing slab to ensure it is level and in good condition.

• Installing an insulating layer to maximize energy efficiency.

• Installing the heating system and connecting it to energy sources.

• Pouring a screed and laying the final covering.

Choosing the right material and its budget implications

The choice of materials for your underfloor heating also significantly impacts the overall cost. Insulations, heating cables, and pipes can vary in price and quality. It is therefore wise to choose your suppliers carefully like Leroy Merlin, Castorama, Brico Dépôt, and compare the available products.

Insulation materials and their cost

Good insulation is crucial to maximize the energy efficiency of underfloor heating. Here are some common materials:

• Insulation panels: Made of expanded polystyrene or polyurethane, they are widely used for their effectiveness.

• Insulating screed: May include lightweight aggregates for better insulating power.

• Reflective materials: Help to reflect heat back into the room instead of losing it through the floor.

Funding and available aid

In the context of energy renovations, several financial aids can be requested, such as tax credits or government grants. It is essential to inquire about the measures in place to facilitate the adoption of innovative and sustainable solutions. Websites like BatiChauffage or Mon Chauffage can provide detailed information about these options.
