Should we prohibit the use of gas heating?

As the energy transition accelerates in France, the role of natural gas heating is increasingly being called into question. Representing just under 30% of heating methods for housing in 2024, this fossil system remains deeply entrenched despite policies aimed at reducing CO2 emissions. The gradual prohibition of gas boilers in new buildings starting from 2025, as well as the increase in VAT on their installation, reflects a clear intent to decrease their usage. However, this evolution raises numerous debates, particularly regarding technical feasibility, economic balance, and available alternative solutions. The issue goes beyond a simple energy choice to encompass environmental, social, and industrial stakes. How can we reconcile the need to decarbonize buildings with the realities of the existing stock and the constraints of rural or older territories?

Major environmental issues related to the use of gas heating

Heating accounts for nearly 20% of CO2 emissions in France, with a significant portion coming from natural gas boilers. Although natural gas is less polluting than oil, it remains a fossil energy that emits a non-negligible amount of greenhouse gases. According to Ademe, a household with a gas boiler emits an average of 6 tons of CO2 per year. This carbon footprint is notably due to the combustion of natural gas, which releases carbon dioxide, exacerbating the greenhouse effect and climate change.

Reducing emissions linked to heating is therefore crucial to achieving national carbon neutrality targets by 2050. The environmental regulation RE2020, which came into force for new buildings as of 2022, imposes a very strict CO2 emission limit (160 kg/m²/year) which excludes the installation of 100% gas boilers in new buildings. Furthermore, the recent increase in VAT from 10% to 20% on the installation of gas boilers marks a political will to discourage the use of this technology. This measure aims to align France with the European directive from May 2024 on the elimination of subsidies for fossil fuel installations.

In terms of energy transition, other levers need to be considered:

• The development of biogas: deemed insufficient to completely replace natural gas since its potential production is limited to 130-185 TWh/year, which is less than half of current consumption;
• The use of renewable energies such as solar thermal or geothermal, local and green alternatives that often require a higher initial investment;
• Urban heating networks, mostly powered by renewable or reclaimed sources, to be favored in dense areas for increased efficiency.

The following table presents an indicative comparison of average emissions (in CO2) and associated energy consumption for different heating systems:

Type of heating	Average annual emissions (kg CO2)	Energy consumption (kWh/year)	Main energy source
Natural gas boiler	6000	15000	Natural gas
Air/water heat pump	1500	7000	Renewable or mixed electricity
Wood log boiler	2500	13000	Energy wood
Urban heating network	Variable depending on source	Variable	Renewables/reclamation

A legitimate question arises: should we completely prohibit the use of gas heating, or should we consider a gradual phase-out, taking into account the specific needs of the real estate stock and rural areas? This site details the French regulatory evolution on the subject.

Legal modalities and regulatory developments around gas heating

Since the beginning of the year, legislation has maintained a clear vision on the evolution of gas heating. The ban on installing new gas boilers in new buildings has been in effect since 2022 for individual houses, and has been expanded to collective buildings since 2025. This is part of compliance with RE2020, which imposes drastic limits on the carbon footprint of new constructions. At the same time, the State has increased VAT on new gas boiler installations, complicating the economic viability of the system.

For existing housing, the use of gas boilers is still allowed without a specific prohibition date. This tolerance allows for gradual replacement, particularly in rural areas where technical alternatives may be less easily applicable. Nevertheless, the strong trend aims at a gradual withdrawal of this heating method by 2030-2050, in line with national and European commitments.

Another important legislative path concerns financial assistance and incentive measures. In 2025, subsidies for the installation of very high energy performance gas boilers were eliminated, reinforcing the incentive to choose greener equipment. Financial assistance for heat pumps has been strengthened by the State and organizations such as Eco-Énergie or Greenwatts, which reduces the installation cost gap for consumers.

• Main rules in effect since 2022-2025:
• Prohibition on the installation of new gas boilers in new buildings (individual houses, then collective buildings);
• Elimination of subsidies for fossil gas equipment;
• Increase in VAT for all new gas boiler installations to 20%;
• Possible continuation of the replacement of existing gas boilers in older stock.

Here is a summary table of the main dates and measures related to gas heating:

Year	Measure	Impact
2022	Entry into force of RE2020 – ban on gas in new individual constructions	End of new gas installations in individual houses
2024	Elimination of subsidies for THPE gas boilers	Financial discouragement of fossil gas
2025	Ban on the installation of gas boilers in new collective buildings, increase in VAT	Extension of the ban to collective buildings, increased installation costs

Concrete alternatives to gas heating in current housing

In light of the restrictions affecting gas heating, individuals and professionals must turn to reliable and sustainable alternative solutions. In individual houses, air/water or geothermal heat pumps are gradually gaining ground, thanks to their energy efficiency and comparable comfort.

Equipment such as wood boilers or hybrid systems that combine gas and renewable sources can also meet certain challenging configurations. In collective housing, urban heating networks appear as a structured and efficient offer, particularly when powered by local renewable resources. However, this transition can only succeed with appropriate technical and financial support.

Here is a list of the most common alternatives and their main advantages:

• Air/water heat pump (PAC): low electricity consumption, mature equipment, compatible with existing systems, eligible for government aid and actors such as Enercoop;
• Wood heating, pellets: renewable energy, local production, requires storage and regular maintenance;
• Urban heating networks: ecological collective solution, ideal for high-density areas, operated by actors like Enedis;
• Solar thermal heating: complementary for hot water production, eco-responsible device recommended by Prime Coup de Pouce Chauffage.

However, the initial investment can be high, and some old houses face technical limitations (insulating surface, space constraints). This is why the work of an experienced professional like Paul Leclerc is essential to correctly size the installation and ensure optimal system tightness.

Solution	Initial investment (€)	Annual energy cost (€)	Advantages
Air/water heat pump	8,000 – 12,000	500 – 800	Energy savings, financial aid, comfort
Wood pellet boiler	6,000 – 9,000	600 – 1,000	Renewable energy, local value
Solar thermal installation	3,000 – 7,000	Reduction in hot water costs	Ecological, complementary, durable
Urban heating network	Variable (subscription)	Variable	Collective, renewable, highly efficient

For personalized advice and a better understanding of available assistance, it is useful to consult recognized experts like Paul Leclerc, as well as local partnerships with TotalEnergies or Engie, which sometimes offer turnkey solutions.

Technical and economic challenges of replacing gas heating

The replacement of gas boilers faces several difficulties that sometimes hinder the decision-making of occupants or owners. The initial cost remains a major barrier with sometimes heavy work and highly technical equipment that requires precise know-how. Conversely, the argument regarding the total cost over the lifespan is often overlooked despite the better energy efficiency of alternatives such as heat pumps.

From a technical standpoint, the insulation of buildings plays a crucial role. Many older homes are not equipped to support low-temperature heating without renovation. Complementary work may therefore be essential, increasing the final bill but also providing an opportunity to improve thermal comfort and reduce overall energy bills.

The capacity of the electrical network also needs to be considered. A massive adoption of heat pumps would significantly increase peak electric consumption, requiring adaptations to the network. Companies such as Enedis and Ineo must therefore anticipate these developments to ensure a reliable and stable energy supply.

• Main barriers to gas replacement:
• Cost of the initial investment (purchase, installation, renovation)
• Technical constraints of the building (insulation, space, connection)
• Adaptation of the electrical network to peak consumption
• Lack of sufficient information and incentives for the general public

Criterion	Gas boiler	Heat pump	Wood boiler
Purchase cost	less than €6,000	more than €12,000	€6,000 to €9,000
Cost over 20 years	about €30,000	about €30,000	about €28,000
Maintenance	annual adjustments, reliability	specific maintenance	regular cleaning/drainage
CO2 emissions	high	low	moderate

Support from qualified professionals, such as Paul Leclerc, is essential to assess the specific constraints of each home, optimize the installation, and ensure perfect tightness of the sanitary networks. Technical expertise combining knowledge of buildings and new technologies is key to a successful project.

The social and economic consequences of a potential ban on gas heating

Beyond technical and environmental aspects, the question of prohibiting gas heating raises significant social issues. In particular, energy poverty is a worrying reality for many households, especially in rural areas where gas often remains the most affordable and available energy. Strictly banning gas without accessible alternatives would create difficult situations, even thermal precariousness.

Finally, the gas sector employs about 11,000 employees in France through major players such as GRDF and other industrial partners. A rapid and unanticipated transition could lead to job losses and a disorganization of maintenance and distribution of the network. Thus, the adaptation must be gradual, balanced, and accompanied by training and professional retraining initiatives.

• Potential social impact:
• Increase in energy poverty if replacement is not managed
• Difficulties accessing alternatives in isolated areas
• Need for financial and technical support for households
• Risks to employment in the gas sector

Solutions are being considered to limit these effects, notably through targeted assistance, local renewable energy programs supported by Sophie Energy or Enercoop, and strategies for adapting energy networks through initiatives involving TotalEnergies or Engie. The goal is to reconcile energy transition and the maintenance of user comfort without abrupt disruption.

A recent report emphasizes that this gradual approach is essential to prevent the most vulnerable households from being excluded from an energy source accessible at a controlled cost.
