Welcome to CLAGE

Portrait: We introduce ourselves.

Simply efficient.
We are a medium-sized industrial company for energy-saving hot water appliances from the northern German Hanseatic city of Lüneburg. More than 270 employees are responsible for development, design, production and sales of the energy-efficient devices with high quality standards. All under one roof!
2017: We are TOP 100
In June 2017, CLAGE was awarded the Top 100 seal by science journalist Ranga Yogeshwar and is now one of the Top 100 most innovative companies. The competition uses a demanding selection procedure to assess the innovation potential of German medium-sized companies. Among other things, the innovation success, the innovation climate, the organization, the external orientation and the management are evaluated.
Expert
As a specialist for decentralised hot water supply, we offer a wide range of products with many individual solutions. From A for air hand dryer to Z for Zip drinking water systems – everything has to do with hot water. As market leader for instantaneous water heaters, we are constantly looking with great commitment for new solutions and innovations in all areas of decentralised water heating. For this we have been awarded as an ambassador for innovation by the Chamber of Industry and Commerce.
Efficiency
The “E” in our name, CLAGE, is accentuated, because “E” stands for efficiency. But what do we understand by this and how do you benefit from it? Much even: A large product range of energy-efficient devices, which are characterized by clever technology, small and compact design, as well as clear and robust construction. A corresponding way of working is also part of it. Our customers feel the "short distances" to our competent and trained employees.
Responsibility
Thanks to great passion and personality, you can feel the responsibility at CLAGE. This is noticeable in consulting and service. Of course, we also take responsibility for our products. Because the energy- and water-saving devices give you the good feeling of safety, hygiene, comfort and reliability.
Flexibility
We not only want to sell you "one unit", but also offer you energy-efficient decentralised hot water solutions. This includes a high degree of flexibility in order to develop individual solutions. And we pursue many goals: Saving energy and water, comfort, hygiene, durable products, easy installation and operation, fast and good service. Smart technology is a prerequisite.
For the sake of the environment
The process up to the finished product can be described as extremely sustainable and is continuously put to the test. We work in accordance with the ISO 14001 environmental management standard, and we go one step further, because we pay attention to the highest material efficiency. The units are designed in such a way that many parts such as heating cartridges can be replaced. This reduces waste and increases the service life of the products. When we work with service providers, these are preferably local partners. This also protects the environment.
Quality since 1951
"Finally and immediately warm water" is what many of our customers have been saying for several decades. As early as 1951, Claus-Holmer Gerdes began selling small instantaneous water heaters. Today, we are a second-generation owner-managed industrial company.
