A company full of energy

The STIEBEL ELTRON group is a global market leader in technology for building services and renewable energy.

Since 1924, the company's success has depended upon its level of technical competence, high quality standards, innovation, reliability and customer-oriented service. Five national and international production facilities, 24 subsidiaries around the world, plus sales organisations and representatives in 120 countries translate into a truly global presence for STIEBEL ELTRON. Approximately 40 percent of the company's turnover comes from export.

The company's founder, Dr. Theodor Stiebel, came to Berlin in 1924 with the goal of developing and manufacturing products with low energy consumption, increased safety and greater convenience. This is an objective which still holds true for the company today.

As a family company driven by innovation, throughout product development and manufacture Stiebel Eltron maintains a clear focus on environmentally responsible, efficient and convenient building services. The company relies on over 3100 employees around the world and their expertise at every stage of development – from the initial design, right through to the manufacture of the final product. The result is efficient and innovative solutions for domestic hot water, heating, ventilation and cooling. With its extensive product range, Stiebel Eltron always has the right option to prepare homes for the demands of the future – today. The company is owned by Frank Stiebel and the Stiebel Family Trust, created by Dr Ulrich Stiebel, each of whom holds 50 % equity.
