What InstaHeat does
InstaHeat AG is a Zurich-based cleantech company founded in 2019 that develops and commercializes direct ohmic heating technology for liquids. Its core product, the HeatFlow Series, is a family of 12 miniaturized flow heaters that pass electrical current directly through conductive liquids (milk, milk alternatives, water, wine) via two electrodes, using the liquid's own electrical resistance to generate heat instantly. Available in 2300W and 3000W variants with a 20% peak power boost mode, HeatFlow eliminates the need for traditional boilers and heating elements, addressing mineral deposits, overheating, and energy waste of up to 50% inherent in conventional metallic-element heating systems. The technology is protected by patents filed in the US, Europe, and Asia, and underpinned by a proprietary fully galvanically isolated system architecture with intelligent current path control and real-time sensing.
InstaHeat operates a B2B OEM-embedded business model, selling HeatFlow as an integrated component within commercial equipment manufactured by partner companies. Its first commercial deployment is with Rex Royal, a leading Swiss commercial coffee machine manufacturer, for integration into the S3-series professional coffee machines signed in January 2026. The company pursues additional OEM partnerships with international appliance manufacturers in Europe and Asia, several of which are currently testing prototypes. Revenue is generated through hardware sales of the HeatFlow devices and technology licensing/OEM partnerships, with no public pricing disclosed.
InstaHeat's go-to-market combines direct enterprise field sales to coffee machine and appliance manufacturers with event-driven lead generation (notably the HostMilano 2025 world debut) and content marketing. Target customer segments include commercial coffee machine manufacturers (primary), water infrastructure operators, food and beverage processors for pasteurization, and household appliance OEMs. The company has approximately 7 employees and has raised roughly CHF 500,000 in equity and CHF 1 million in competitive grants, primarily from Swiss innovation programs. InstaHeat's founders played a central role in securing unanimous IEC member-country approval for new global safety standards (effective January 2025) that formally recognize direct ohmic heating of liquids as safe, creating a significant regulatory moat for the company's go-to-market.
