More than 300 euros per megawatt hour (MWh): According to Capital.fr, this threshold was exceeded at the beginning of March 2022 as a result of the invasion of Ukraine by Russia. An increase that, in addition to the environmental challenges of reducing fossil fuels – raised by the recent report by the International Group of Experts on Climate (IPCC) – inevitably raises the question: how to save gas? What are the possibilities to reduce the consumption of your house? Geo.fr has identified 5 implementation tips.
1. Adjust the room temperature as needed
“Above all, the most effective measures to reduce your gas bill are those that consist of reducing heating requirements. The less you heat, the lower the heat loss“, explains Marion Deridder-Blondel, Marketing Director of ENGIE France BtoC. However, there are tools to finely regulate the temperature at home. “Buying a connected thermostat costs less than 200 euros and gives you significant savings. This way you can lower the temperature when you are not in the accommodation“, advises the expert. According to ADEME, up to 15% energy savings can be achieved by programming. Some gas suppliers offer deals that are compatible with this device.
Turning the thermostat down does not necessarily mean sacrificing comfort, quite the opposite! Although the temperature of 19°C is often mentioned, with reference to standards such as NF EN ISO 77 30 (dedicated to the ergonomics of thermal environments in offices), it is not just about this number. “Comfort is not only a question of the air temperature, but also of the “radiated temperature”. When skiing, for example, it can be 0°C, but you are comfortable because the sun is shiningillustrates Marion Deridder-Blondel. In a well-insulated home, it is the warmer walls that radiate more. This explains the fact that you can feel better at 18°C in well-insulated homes than at 20°C in poorly-insulated homes.“
2. Insulate your home to prevent heat loss
Thermal insulation not only improves comfort by exploiting the temperature radiated by the walls (see above), but above all it is a particularly effective way of preventing heat loss. If the complete insulation of the apartment requires a significant investment, it can also be done on a smaller scale – and even if you are a tenant, by installing, for example, “door floors” (rigid or flexible rubber rods) between the heated rooms and cold rooms such as basements, attics or garage.
Also remember to have your heating pipes insulated by a professional who will wrap them with an insulating sleeve. Finally, closing the curtains or shutters at night and in your absence can easily prevent heat loss through the windows.
3. Use online consumption tracking
Some gas suppliers allow you to track your consumption online, with a communicating meter associated with specific offers. “One of the problems with the consumption of gas and energy in general is the lack of connection that the consumer makes between his actions and the resulting impact. Energy is not something you see!‘ emphasizes Marion Deridder-Blondel. Offers based on artificial intelligence (AI) therefore make it possible to extrapolate the expected benefit of one or the other action to the final bill.
4. Service your boiler and replace it if necessary
Regular boiler maintenance by a technician is not only essential in terms of your insurance, but also an opportunity to check the technical and safety parameters of your installation. By adjusting the operating mode of the device, the savings achieved vary between 8 and 10%. Another advantage is the increase in the life of the boiler, which can heat you for many years.
However, if your boiler is old (over 15 years old) it may be worth replacing. “There are now “very high energy efficiency” boilers with condensing-based systems that recycle energy, increasing the efficiency of the appliance.explains Marion Deridder-Blondel. In addition, boilers have benefited from significant electronic contributions in recent years. (…), now with the same electronic components as smartphones“.
5. Clean and bleed the radiator
Every year, at the beginning of winter, it’s the same: the radiators need to be bled. This essential gesture not only avoids disappointment – a radiator that’s left desperately cold or noisy – but also avoids unnecessary gas consumption. “In radiators, air takes the place of water. However, if the hot water does not circulate over the entire surface, the radiation will not be transmitted as well‘, Marion Deridder-Blondel indicates near her devices.
While lower consumption remains the best way to save money while reducing our dependency on fossil fuels, the energy transition also includes the development of “biogas”, which specifically results from methanation (the breakdown of organic matter by bacteria) from agricultural waste is produced. “That Energy Transition Act originally planned to reach 10% biogas by 2030, but ambitions are revised upwards given the current context“, the marketing director of ENGIE France confides in BtoC. Some energy suppliers already offer offers that allow them to source from local producers.
