What Kronoterm does

Kronoterm is a Slovenian heat-pump manufacturer headquartered in Gomilsko, founded in 1976 as a locksmith workshop and formalized as a company in 1990. It designs, manufactures, and end-tests air-to-water, ground-to-water, and water-to-water heat pumps in-house, alongside domestic hot water (DHW) units, using natural refrigerant R290. The product portfolio spans residential lines (ADAPT 2, VERSI, ETERA, WPG, WPL, GEOS), DHW units (ESSENTA, SMAX, ST), and a modular commercial platform (ADAPT MAX), supported by the CLOUD.KRONOTERM cloud platform for remote management and monitoring.

The company operates as a family-owned business under second-generation leadership (CEO Bogdan Kronovšek since 2010), with a workforce of 120+ specialists covering R&D, manufacturing, and service. Its installed base exceeds 110,000 systems, and units are certified to EHPA, ISO 9001, TÜV, and Keymark standards, with country-specific approvals such as BAFA in Germany.

Kronoterm sells exclusively through an authorized partner and installer network across 18 European markets, with case-study customers in hospitality, real estate, agriculture, healthcare, and general business. Revenue is generated from hardware sales, extended warranty, service and maintenance (including remote diagnostics from the 2026 service center), and OEM/private-label manufacturing for other brands.
