Vaillant is one of the largest manufacturers of boilers and heating systems in the world. The Vaillant Group is headquartered in Germany and currently employs over 12,000 people worldwide.
Dating back to the late 19th century, founder Johann Vaillant patented the first closed system boiler, meaning it was possible to heat water without the contamination inevitable with more traditional methods.
Vaillant has continued to set industry standards ever since with notable innovations including the first wall-hung heater and condensing boiler technology.
Despite revenues of over €2 billion, Vaillant is still family owned to this day and maintains development and manufacturing facilities in the UK as well as Germany, France, Spain, Italy, Slovakia, Turkey and China.
