Calentix

Calentix builds and operates waste heat recovery infrastructure that connects data centres with district heating networks, turning unused heat into a reliable, low-cost energy source. Using large-scale heat pumps, the company captures low-temperature waste heat from data centres and upgrades it to usable heat for urban energy systems, addressing both rising fuel costs and decarbonisation needs. By structuring, financing, and operating these assets, Calentix delivers long-term contracted heat supply with infrastructure-like returns, typically secured through 15–25 year agreements. The model reduces energy costs for utilities, lowers cooling costs for data centres, and creates a local, resilient energy source while avoiding upfront investment and operational complexity for partners. Positioned at the intersection of rapidly growing data centre capacity and increasing demand for clean heat, Calentix is building a scalable portfolio in a multi-billion-euro emerging infrastructure market.
