Eibelshausen – September of this year will see the 400th anniversary of the Bosch Thermotechnology factory in Eibelshausen (in central Hesse), one of the oldest industrial operations in Germany and the Bosch factory with the longest history. The roots of the factory in the Dillenburger Land region date back to the year 1613 when a violent storm left a trail of countless uprooted trees in its wake. To make use of the enormous quantities of wood, permission to build an iron furnace was obtained from the Count of Nassau-Dillenburg and a charcoal-fired facility was started up in the second half of the year. Metal has been processed since those days.

In the 18th century at the latest, the production of raw iron was complemented by an iron casting operation producing stoves and stove plates which displayed a high level of craftsmanship and artisanship. By the end of the 18th century, the factory had emerged as a local centre of iron production and processing. From 1791 its economic importance was symbolised by a new furnace which was the largest and most powerful of its kind in the entire Dill region.

Stoves from Eibelshausen were much sought after already in the 19th century. They were used both for cooking and for space heating. Particularly impressive models such as the “Bavarian Cooking Plate Stove” combined both functions, allowing families to heat their home and cook meals at the same time. At the other end of the scale, the Eibelshausen plant also produced a compact “Breakfast Stove” weighing only 35 kilogrammes for mobile use e.g. on construction sites. This way the Eibelshausen factory demonstrated its capacity to innovate and respond to market requirements early on.

From 1883 onwards Eibelshausen operated as part of the Hessen-Nassauischer Hüttenverein group formed by the Jung family from the Siegerland region. The factory continued to focus on the production of stoves. Apart from the traditionally ornamented cast-iron products, Eibelshausen also started to make enamelled stoves for upper middle-class households.

Having invested heavily in the modernisation of its foundry operations during the 1920s, the Hüttenverein group found itself in financial straits against the backdrop of the global economic crisis. In 1932, it agreed to form a “community of interest” with Buderus’sche Eisenwerke which had emerged as the industry leader in the Lahn-Dill region. The agreement became effective on January 1, 1933 and essentially meant that Hüttenverein was taken over by Buderus. At the end of 1935, it was formally merged into Buderus.

During World War II, all metal processing companies in Germany, including all Buderus plants and the Eibelshausen factory, were required to suspend their civil manufacturing activities and contribute to the war effort.

The production of stoves was resumed at Eibelshausen immediately after the end of the war. In those years the product range also included such household implements as potato baskets and muzzles. The second half of the 1950s saw Eibelshausen emerge as the Buderus Group’s central manufacturing site for coal-fired stoves. The factory turned out some 2.5 million coal-fired stoves by the year 1975. Around this time the era of the stand-alone stove came to an end as the advance of central heating systems was unstoppable. For a while the factory produced a variety of different heating components until Buderus decided to pool its production of DHW cylinders at this site.

Buderus became part of the Bosch Group in 2003. Today the Eibelshausen factory is part of Bosch’s Thermotechnology Division. Since 2007, Eibelshausen has produced DHW cylinders for a variety of brands including Buderus and Junkers; the four millionth cylinder was manufactured only recently. Some 310 people are employed across development, product management and DHW cylinder production.
