Junkers is a historic German engineering brand, primarily known today for Bosch-manufactured gas heating systems, boilers, and water heaters, as well as aviation-inspired wristwatches.
Junkers is a renowned name in German engineering, originally founded by Hugo Junkers as an aviation manufacturer. Today, the brand operates primarily in two distinct sectors: heating technology and timepieces. In the home comfort market, Junkers (now part of Bosch Thermotechnology) is a leading provider of gas water heaters, condensing boilers, and heat pumps, known for their efficiency, reliability, and safety features.
These systems are widely used across Europe and beyond for domestic hot water and central heating. In addition to thermotechnology, the Junkers legacy continues in a popular line of pilot-style wristwatches. These timepieces, often featuring mechanical automatic movements, pay tribute to the historical Junkers aircraft designs. This category includes user manuals and support documentation for both the Junkers heating appliances—covering installation, maintenance, and safety instructions—and the Junkers watch collections.
