A company full of energy

STIEBEL ELTRON is a group of companies with a decidedly international outlook, and can rightly claim to be a global market leading supplier of technology for building services and renewable energy equipment.

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, 21 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. An objective which still holds true for the company today. The company is owned by Frank Stiebel and the Stiebel Family Trust, created by Dr Ulrich Stiebel, each of whom holds 50 % equity.

Investment in innovation – the STIEBEL ELTRON production facilities

The Holzminden site is the head office of the STIEBEL ELTRON Group, and also its largest production facility. Alongside the worldwide administration and sales organisation, it is also home to the production site of many millions of electrical DHW and heating appliances, as well as plants and systems that use renewables. Added to this, is a further high tech factory in Eschwege (Germany), which manufactures small water heaters, water boilers, hand dryers and all the thermoplastic components required within the group. There are also three international production facilities in Poprad (Slovakia), Ayutthaya (Thailand) and Tianjin (China). Photovoltaic modules complete the product portfolio. 

Active support – the STIEBEL ELTRON corporate philosophy

Traditionally the company has been oriented towards wholesalers and contractors. This focus remains central to the company's philosophy today. STIEBEL ELTRON values the active support of its partners and provides training, plus sales and service support. The retail trade, contractors and engineers/designers have access to the training academy in Holzminden for product support. Last year alone, more than 10,000 participants took advantage of the wide range of courses on offer at the academy. The whole product range is showcased in six sales centres in Germany, including permanent exhibitions – mostly with 'live' systems.

An ambitious research, development and investment program has been designed to equip STIEBEL ELTRON for the years ahead. During 2014, Group investments in its production sites in Germany climbed above the €10 million mark once again. Stiebel Eltron is currently building a new training and communication centre in Holzminden. By mid 2015, a new conference suite will be located at the Group's head office offering versatile meeting rooms for national and international visitors.
