Hungary-based energy innovator Heatventors Kft has secured €4 million in Series A funding to expand its intelligent thermal energy storage solutions globally
Powering global growth with smart energy storage
Heatventors Kft, a trailblazer in intelligent thermal energy storage, has closed a successful €4 million Series A funding round aimed at accelerating its international growth and advancing the development of its high-efficiency thermal batteries.
With the growing demand for sustainable cooling and heating technologies, this investment positions Heatventors to scale its operations in key global markets and further enhance its already proven solutions.
The fresh capital injection will strengthen Heatventors’ technical infrastructure, fuel product development for large-scale, multi-megawatt storage applications, and support the company’s market entry strategy in regions with high cooling and heating demands, particularly Europe and the Middle East.
Intelligent thermal batteries for a greener future
Founded in 2017, Heatventors has developed and patented a proprietary solution known as the Intelligent Thermal Battery. Unlike traditional systems, these batteries combine advanced regulation technology with thermal energy storage to deliver up to 25% energy savings in both cooling and heating operations. The technology is designed to optimise energy use, enable renewable energy storage, recover waste heat, and ensure dependable HVAC performance.
These thermal batteries are not only energy-efficient but also highly versatile, making them suitable for a wide range of applications, from data centres and industrial manufacturing to district heating networks and large-scale cooling systems.
With nearly 80 storage units already installed across seven countries, Heatventors has shown real-world impact. Installations can be found in Hungary, Germany, Oman, and Portugal, with a growing presence in additional markets. Customers include energy companies, insurers, industrial firms, and hotels, showcasing the solution’s cross-sector appeal and reliability.
Support from leading investors
The Series A round attracted investment from a strong consortium of climate-focused and clean technology investors. Leading the round was Hungary’s Kék Bolygó Klímavédelmi Magántőkealap (Blue Planet Venture Capital Fund), supported by pan-European impact investor InnoEnergy and Germany’s Impulsus Clean Technologies GmbH. V3 Partners Investment Zrt., also based in Hungary, acted as the investment advisor throughout the process.
This backing not only brings capital but also access to a vast network of expertise and markets, enabling Heatventors to enhance its R&D, scale production, and enter new geographies with confidence. With the rising demand for clean energy storage solutions globally, particularly those that reduce carbon emissions and increase energy efficiency, Heatventors is well-positioned to become a key player in the thermal storage market.
The global demand for cooling and heating
As global temperatures rise and energy systems transition to more sustainable models, thermal energy storage is becoming an essential component in energy infrastructure. Intelligent solutions, such as Heatventors’ thermal batteries, offer a sustainable and cost-effective alternative to traditional energy consumption models, particularly in high-demand sectors like data centres and district cooling.
The successful Series A funding round marks a significant milestone in the company’s journey. With a proven product, strong investor backing, and a clear path to international expansion, Heatventors is poised to make a lasting impact on the global energy landscape.
