GreenHeat

About

GreenHeat is a private headquartered in France with approximately 10-50 employees specializing in Other.

GreenHeat is the first French provider of renewable heat energy recovered from wastewater and greywater. The company operates by recovering waste heat from hot water rejection at industrial sites and aquatic centers, then converting this thermal energy to preheat incoming cold water. This eliminates the need for traditional fossil fuel heating while reducing energy consumption by up to 60%. GreenHeat handles the full project lifecycle: feasibility studies, equipment procurement, installation without operational disruption, system management, and maintenance. The company uses the Obox I heat recovery system, which features automated cleaning and remote monitoring. Clients benefit from fixed-price, long-term energy contracts (5-10 years) with guaranteed cost savings compared to fossil fuels. Operating sites across France demonstrate significant energy recovery (ranging from 59.9 to 474 MWh annually) and CO2 emissions reduction (32 tonnes per site annually). GreenHeat is part of the G2E group alongside Evolsys (heat recovery distributor) and EhTech (manufacturer of recovery systems).
