Type of housing: Detached house, apartment, etc.
Area: The surface area to be heated directly impacts the choice of system.
Insulation: Good insulation can significantly reduce your heating needs.
Budget: What is the amount you can invest initially and in the long term?
Step 2: Choose the appropriate heating system
Once your needs are defined, it's time to choose the system that suits you. In 2025, the market offers several options:
Central heating: Such as Ferroli or Viessmann boilers, often prized for their efficiency.
Heat pump: An investment for the future, allowing you to save energy.
Underfloor heating: For optimal comfort and uniform heat throughout all rooms.
Radiators: Classic options, with brands like Atlantic and Chaffoteaux standing out.
Step 3: Size your installation
Sizing is a crucial step that determines the energy efficiency of your system. Proper sizing would limit your energy expenses and guarantee a constant ambient temperature. A professional will help you perform calculations based on:
Criterion | Impact on installation |
|---|---|
Room volume | Determines the power needed for each emitter. |
Insulation | Reduces heat losses, influencing the choice of boiler or pump. |
Use areas | Some areas may require more heat depending on their daily use. |
Step 4: Install the heating system
Finally, the installation step must be carried out by a professional to ensure compliance and efficiency of the system. This includes:
Installation of emitters: Radiators, underfloor heating, etc.
Connection: Links between the heat generator (boiler, heat pump) and the emitters.
Testing: Checking tightness and pressure to ensure proper operation.
Regulations and standards concerning heating
With the evolution of ecological concerns, regulations impose specific standards to be followed during the installation of heating systems in a new house. The laws in France mainly aim to reduce environmental impact and improve energy efficiency.
Current environmental standards
In 2025, requirements are tightening around heating equipment, and several criteria must be considered:
Energy consumption: Estimating usage in kWh per year is essential.
Greenhouse gas emissions: Devices must meet strict standards.
Energy labeling: Appliances, such as those from Buderus or Danfoss, must carry a label to inform about their efficiency.
Periodic control: Certain installations must undergo regular maintenance to ensure compliance.
Installer obligations
The professional must fulfill several obligations to remain compliant and ensure proper functioning:
Obligation | Details |
|---|---|
Compliance with standards | Adherence to current standards during installation. |
Notification to the administration | Inform about the installed systems via specific forms. |
Expert advice | Offer customer support on usage and maintenance. |
