Founded in 2017 in Hungary, Heatventors has created a proprietary Intelligent Thermal Battery that combines thermal energy storage with advanced control software to cut cooling and heating energy use by up to 25%. The modular system can recover waste heat, integrate renewable generation and support multi-megawatt applications, making it suitable for data centres, industrial manufacturing, hotels and district-scale networks. The company has deployed nearly 80 storage units across seven countries, including Hungary, Germany, Oman and Portugal, demonstrating early commercial traction. Customers range from energy utilities and insurers to large industrial firms. With demand for sustainable HVAC solutions growing, Heatventors plans to scale production, deepen R&D and enter additional European and Middle-Eastern markets. The new capital will also bolster its technical infrastructure to support larger-scale installations. Management aims to position the firm as a key global player in the thermal energy storage segment.
