Lancey

The core of Lancey's business is its smart radiator, which addresses the residential and commercial building markets. The product's primary function is to store electricity during off-peak hours, when it is cheaper and has a lower carbon footprint, and then use this stored energy to heat the room during peak hours. This process can lead to heating bill reductions of up to 50%. The system is particularly beneficial for homes with rooftop photovoltaic panels, as the EMS and battery work to maximize the self-consumption of solar energy. The product combines an infrared radiant front with a self-learning algorithm and various sensors to optimize thermal comfort and energy use. Users can manage the system via a dedicated mobile application.

Lancey's business model involves selling these smart radiators to a range of clients, including individual consumers, social landlords, and property developers, for both new builds and renovations. The company established strategic partnerships and secured investments from major players like ENGIE New Ventures and Stelpro, a Canadian radiator manufacturer, in 2019. Throughout its history, Lancey has received several awards, including a CES Innovation Award in 2018, and has been supported by programs like the EU's Horizon 2020. After facing financial difficulties and entering receivership in June 2024, the company was acquired in November 2024 by Votre Artisan Vert (VAV), a group specializing in energy renovation, which plans to continue the Lancey brand and technology.
