Vaillant has long been established in the world of heating, with a prestigious heritage that goes as far back as 1874. They have had to constantly adapt and evolve to new technologies over this stretch of time, and this has allowed them to be more innovative than modern brands.

To bolster its offerings, Vaillant partners with some of the most recognisable associations when it comes to hot water systems including: Association of Plumbing and Heating Contractors, Chartered Institute of Plumbing and Heating Engineering, Home Builders Federation, Industrial & Commercial Energy Association and Sustainable Energy Association.
