Gas or electric heating: which system is the most cost-effective in 2025?
For years, the question of choosing between gas heating and electric heating has particularly concerned the French, especially in the context of construction or renovation work. In 2025, this question takes on an even more crucial dimension with tariff changes and legislative developments regarding energy. Which system is most suitable for your situation? Let's analyze the advantages and disadvantages of these two solutions for economical and comfortable heating together.
The stakes of choosing between gas heating and electricity
Over the years, the energy choices of the French have evolved. While historically electricity was largely preferred for new connections, since 2011, natural gas heating has gradually taken center stage. In addition to comfort and efficiency, the choice of an energy source also depends on installation and operating costs. Let's analyze these factors in detail.
The advantages of natural gas heating
Gas heating has managed to attract many due to several undeniable advantages:
Thermal comfort: Natural gas provides a gentle and uniform heat, without drying the air, unlike some electric systems that can create a cold sensation when they turn off.
Operating cost: In terms of profitability, the cost of electricity continues to rise, while the price of gas, which remains lower on average, makes it economically attractive for heating (estimated at €0.1531 per kWh in 2025).
Perception of comfort: Users report a more pleasant heating experience thanks to modern boilers, such as those from brands like Saunier Duval or De Dietrich, which offer high efficiency.
The disadvantages of gas heating
Despite these advantages, it is essential to take into account some associated disadvantages:
Installation cost: The installation of a gas heating system is often more expensive (between €4,000 and €9,000) due to the need for specific boilers and a distribution network.
Connection to the grid: For 74% of French municipalities, natural gas is not accessible. For these localities, alternatives like propane or electric heating must be considered.
Electric heating: an economical alternative to installation
Electric heating is often seen as a more economical installation option. This mode of heating presents advantages that can appeal to many households.
The advantages of electric heating
Low installation cost: Electric heating systems, such as boilers from brands Atlantic or Bosch, have lower installation costs (between €1,500 and €4,500).
Simplicity and speed: The installation of electric radiators can be quick and does not require gas piping, which simplifies the process for new homes.
Thermal modulation: Some recent models, like those with inertia technology, allow for better heat regulation and optimize daily comfort.
The disadvantages of electric heating
However, there are limitations that deserve mention:
High consumption cost: Over the long term, the cost of electricity (estimated at €0.2016 per kWh in 2025) is often more expensive compared to gas. This is a factor to consider, especially for medium to large-sized homes.
Restricted thermal comfort: Electric heating can cause air dryness, which can be uncomfortable in winter.
Comparison of heating costs in 2025
To make an informed decision, let's see how heating costs unfold based on different types of housing.
Type of housing | Annual cost gas heating | Annual cost electric heating |
|---|---|---|
30 m² studio | €648.15 | €907.20 |
70 m² apartment | €934.78 | €2,064.30 |
130 m² house | €2,367.30 | €3,833.70 |
Through these figures, it becomes clear that gas heating is less expensive and more economical in the long term for households with larger spaces.
The future of heating: what alternatives?
In light of climate challenges, France is considering restricting the use of gas boilers. This raises the question of ecological alternatives. In 2026, several options could emerge:
Heat pumps: These systems are increasingly favored due to their low environmental impact and their potential to reduce energy bills.
Wood heating: These systems, particularly with pellet stoves, also prove efficient and environmentally friendly.
The final choice: gas or electricity?
It is undeniable that the choice between gas heating and electricity will depend on several factors such as the size of the dwelling, location, and how you intend to use it. Here are some points to consider to help you with your decision:
Your initial budget for installation. Do you prefer to invest more upfront or to reduce installation costs?
The type of housing you own. Is it a small apartment or a house?
Your consumption habits: are you rather frugal or do you need heating constantly?
In summary, if you are already equipped with a gas system, it is better to keep it. But if you are considering installing a new system, weighing the pros and cons of each option is imperative.
FAQ: Gas heating VS electricity
What is the most economical solution in 2025?
Gas heating generally remains more economical than electricity for most households, particularly in terms of operating costs.
Is natural gas accessible everywhere?
No, about 74% of French municipalities are not served by natural gas, which limits its use.
What alternatives to gas are available to me?
Consider systems like heat pumps, wood boilers, or hybrid solutions that incorporate different renewable energies.
Is electric heating expensive in the long term?
Yes, even though installation is cheaper, the long-term cost of electricity can make this option less economical for heavy users.
What is the environmental impact of gas heating?
Gas, being a fossil fuel, emits CO2, which has an environmental impact. Policies are in place aimed at reducing its use in the coming decades.
