What Clage does
Clage GmbH is a privately held German manufacturer headquartered in Lüneburg, specializing in decentralized hot water supply solutions. The company designs, develops, and sells electronic instantaneous water heaters (E-Durchlauferhitzer) organized across four power classes — E-Klein for handwash basins, E-Kompakt for kitchens, E-Komfort for showers and bathrooms, and E-Modul for hidden installation — alongside hot water storage tanks (5–120 liters), apartment transfer stations (Wohnungsübergabestationen), and Zip HydroTap and Lunaris branded water systems for commercial filtered and boiling water applications. Core technology centers on electronically controlled heating elements with a proprietary "Smart Control" feature aimed at energy consumption optimization, positioning the products against Germany's GEG building energy regulations.
The company operates a dual go-to-market combining a Fachpartner (specialized trade partner) network of certified plumbers and installers across Germany and international markets with a direct-to-consumer e-commerce shop. Revenue is generated predominantly through hardware sales across the product range, supplemented by after-sales services including spare parts (Ersatzteilshop), training programs (Schulungen & Live-Seminare), and device registration via the MyCLAGE customer portal. Pricing is quote-based through the B2B Fachpartner channel with no public disclosure. International presence spans at least 11 European country markets supported by a multilingual website (German, English, French, Polish, Dutch, Swedish, Russian, Hungarian, Czech, Norwegian, Slovak, Ukrainian).
Clage self-describes as the market leader for small instantaneous water heaters (Kleindurchlauferhitzer) in Germany and holds double Stiftung Warentest test winner (Testsieger) status. The company was founded in 1951 and operates as an independent GmbH with no disclosed parent, external investors, or acquisition activity, employing 251–500 people. Its customer base spans residential end-users, commercial and institutional facilities, and the trade partner installers who serve as the primary distribution channel.
