In a context where the energy transition has never been more crucial, the replacement of an old boiler appears to be an essential step. In 2025, economic and environmental issues intertwine to offer French households the opportunity to reduce their expenses while improving their quality of life. Thanks to CEE grants (Energy Savings Certificates), many efficient heating solutions are accessible, notably the condensing gas boiler. This article guides you through the advantages of this approach, the available aids, and the conditions required to fully benefit from them.
Why replace your old boiler?
Replacing an aging boiler is essential for several reasons. On one hand, older devices are often less energy-efficient, resulting in high heating bills. On the other hand, legislation is evolving towards stricter standards regarding greenhouse gas emissions.
- Financial savings: By replacing your old boiler with a high-performance model, you can reduce your heating expenses by 25% to 35%.
- Improved comfort: Modern new boilers offer better thermal comfort due to more even heat and quieter operation.
- Environmental impact: Modern boilers, especially condensing boilers, emit less CO2, thus contributing to the fight against climate change.
The ideal choice: the condensing gas boiler
Among the available choices, the condensing gas boiler stands out. This innovative technology uses combustion gases to preheat return water, improving energy efficiency. With an efficiency that can reach 110%, it allows for real savings on your gas bills.
Furthermore, this boiler is compatible with various heating infrastructures, making it particularly versatile. Whether you are already equipped with central heating or are considering a new installation, the condensing gas boiler adapts to your needs.
CEE grants: a valuable aid for the transition
In 2025, the CEE grant system proves to be a major asset for households looking to invest in efficient heating equipment. This aid is funded by energy suppliers such as Engie, EDF, and TotalEnergies, who are required to encourage their customers to make energy savings.
How CEE grants work
CEE grants are allocated to individuals who make improvements to enhance the energy efficiency of their homes. Here are some key points to consider:
- Eligibility: The work must pertain to energy-efficient heating elements, such as condensing gas boilers.
- Amount: The amount of the grant depends on the chosen equipment, the quality of the installation, and the resources of the requesting household. For a condensing model, this can go up to €1,400 for modest households.
- Conditions: It is imperative to engage a RGE (Recognized Environmental Guarantee) professional for an eligible installation.
How to obtain CEE grants for your gas boiler?
The process to benefit from CEE grants is relatively simple. Here are the main steps to follow:
- Assessment: Have your current installation assessed by a professional, who can recommend the type of boiler best suited for you.
- Estimate: Request several quotes from RGE-certified companies to compare prices and services. This is essential to ensure the validity of your application.
- Grant application: Before signing your estimate, contact the energy supplier of your choice to apply for the grant. You can also seek the help of your RGE professional.
