Celebrating 150 Years

Our Company Milestones

Vaillant are committed to providing customers with energy-saving and easy to operate solutions for heating and hot water.

As one of the world’s leading manufacturers of heating technology, sustainability plays an integral role in the Vaillant Group’s activities. Home and world climate are inseparable and modern heating technology can make an important contribution to achieving climate protection targets. In the UK alone, replacing an old heating system with a new high efficiency boiler can save more than 30% of energy a year, and reduce CO2 emissions by a corresponding 30%. Sustainable heating is central to the Vaillant Group and its operation.
