Tarnoc

What Tarnoc does

Tarnoc is a Netherlands-based climate technology company founded in 2019 and headquartered in Delft. It is developing a novel Turbine Heat Pump designed as a direct, drop-in replacement for traditional residential gas boilers, with a key claimed differentiator being installation achievable within a single day. The company targets residential homeowners seeking sustainable heating alternatives as the European residential gas-heating stock is phased out under decarbonization policy.

The company's product surface is narrow: a single core product — the Turbine Heat Pump — positioned as a sustainable, easy-to-install substitute for conventional gas boilers. The underlying technology is described as a turbine-based architecture rather than a conventional vapor-compression cycle, though technical details, efficiency figures, and TRL status are not disclosed in available data. Pricing and unit economics are not publicly disclosed.

Tarnoc operates a hardware-sales revenue model, selling Turbine Heat Pump units to homeowners. The company is early-stage: it joined the YES!Delft incubator in 2020, received a €25,000 grant from the Rabo Impact Fund in July 2024, and closed a ~$1.37M financing round in June 2025. Leadership comprises three co-founders — Vincent Wijdeveld (CEO), Tijmen de Jong (CTO), and Maurits Vos (CBO) — and the company explicitly states it is still working toward product-market fit. No revenue, customer logos, distribution partners, or commercial deployment scale have been disclosed.
