Even today we maintain the standards of founder Dr. Theodor Stiebel: insisting on the development and production of innovative products with the highest level of quality. When Dr. Theodor Stiebel invented and produced the ring immersion heater in his backyard workshop in Berlin in 1924, he opened the first chapter of STIEBEL ELTRON's successful company history. In 2024 we will turn 100, so join us in looking forward to our anniversary year.
