A Brief History of Both Brands
When it comes to the origins of these two boiler giants, both Vaillant and Baxi boast impressive histories stretching back to the Victorian era.
Vaillant kicked things off in 1874 when Johann Vaillant set up shop in Remscheid, Germany. They've been innovating ever since, from patenting their closed-system water heater in 1894 to introducing the wall-hung "Geyser" in 1905.
You might also recognise their playful Easter Bunny logo, which they've proudly used since 1899.
Baxi's story began even earlier, in 1866, when Richard Baxendale established an iron foundry in the UK. While they started by making steel boilers, they really made their mark with the Bermuda gas-fired back boiler in 1966.
Both companies have kept up with modern times. Vaillant's launched cutting-edge heat pumps using natural gas R290, while Baxi's earned the Queen's Award for Enterprise and Innovation with their Ecogen system.
They're proof that age-old experience and modern innovation can work together perfectly.
