With the dizzying increase in the cost of electricity, the idea of optimizing the use of the most energetic appliances is gaining more and more attention. These days, in fact, energy saving is no longer an option, but a necessity. Electric water heaters are present in many homes thanks to their ability to provide domestic hot water quickly and reliable. However, these are devices that consume a lot of energy: alone they represent about the 17% of the average monthly energy consumption of a familya second percentage only to heating systems.
This high demand for energy, combined with the growing cost of electricity, makes them less convenient than in the past. Despite this, many families, especially in houses for rent or in popular housing, have no economic or practical alternatives to replace them. Among the solutions that promise to cut consumption, the device Elaxdesigned by the Breton start-up Elax Energiestands out for its ability to make electric water heaters more efficient, sustainable and intelligent. Thanks to advanced technology and 4G connectivity, this small device allows you to reduce consumption up to 25% without having to replace your boiler.
How the Elax device works
The Elax device, which is easily installed in less than 20 minutes, acts as a smart thermostat. Thanks to a series of sensors, it constantly monitors the water temperature inside the boiler and automatically adjusts the times and methods of heating.
Connecting to Network 4Gthe device sends the data to an automated processing center, where family consumption habits are analyzed. Based on this information, the system establishes the most efficient moments to heat the water, avoiding waste. For example, if a family uses mainly hot water in the morning and in the evening, Elax limits the heating in the other moments of the day, while maintaining a minimum temperature to guarantee hygiene and comfort.
Another important aspect is the temperature control to prevent the proliferation of the legionellaa bacterium responsible for serious lung infections. In France, this disease causes every year beyond 150 deaths. Elax, ensuring intelligent temperature management, ensures that the water reaches adequate levels to eliminate the health risk without unnecessarily increasing consumption.
Economic and energy savings
According to the data provided by the start-up, the use of the Elax device allows an average saving of approx 110 euros per year on the energy bill. Although the initial cost of the device has not yet been specified, the return on investment is guaranteed within a few years.
But savings are not only cheap: reducing consumption also means Cut CO2 emissions associated with the production of energy, thus contributing to the objectives of global sustainability.
The Elax device is aimed not only at home owners, but also to tenants and social construction managers. Thanks to its ease of installation and the ability to adapt to any electrical water heater, it represents a practical and economic solution to improve energy efficiency without having to replace the entire system.
Its effectiveness has been recognized at national level: in 2023Elax was a finalist in the competition EDF Pulsewhich rewards technological innovations in the energy sector.
