The Vaillant success story begins in 1874: As the tenth child of a master tailor, Johann Vaillant breaks new ground and founds his own craft business as a copper hammer and pump maker in Remscheid. Today, as a leading manufacturer, Vaillant is shaping the market for heating, ventilation and air conditioning technology. The first invention, with which Johann Vaillant changed the market forever, was the gas bath heater "closed system" in 1894. For the first time, water is heated in a closed pipe by a gas flame - without coming into contact with harmful exhaust gases: the revolution in the bathroom. From now on, users can enjoy hot, clean water and also regulate the water temperature. The next great Vaillant invention provides more space in the bathroom: In 1905, Vaillant was the first manufacturer to bring the gas bath heater onto the market as a wall-mounted and space-saving device.
