The original aroTHERM plus heat pump, launched back in 2020, was named the "game-changer" in the industry.
Now six years on, technology has advanced, style has changed, and requirements for a heat pump have progressed. So in June 2026, we launched the remastered aroTHERM plus air source heat pump, taking the old and making it even better.
We opened our £40m manufacturing facility in Derby to start producing our range of uniSTOR high-recovery hot water cylinders. In October 2025, HRH The Princess Royal came to officially open the site.
The range of slimline and standard cylinders has been specially developed to meet the needs of UK consumers for low-carbon, low-temperature heating systems, as well as traditional boiler systems.
As part of a multi-year partnership, we teamed up with Legends and ASM Global to bring a world-class entertainment space to the Derby city centre. The 3,500-capacity venue hosts live music, comedy, family shows, and sporting events.
In 1874, Johann Vaillant founded his company in Remscheid, Germany. 150 years later, Vaillant is represented in more than 60 countries worldwide, providing heating and hot water comfort to millions of people.
The Vaillant Hare, which has been a part of the Vaillant brand for 124 years, has now been brought to life to help make heating simple and easy to understand.
Vaillant launches the remastered ecoTEC plus, putting hours of research and development into updating the much-loved ecoTEC plus range with smart home ready capabilities.
Vaillant’s most innovative heat pump product, the aroTHERM plus air source heat pump, is launched to the market. The low carbon heating solution is increasing in popularity as more homeowners are looking to make more sustainable choices.
Vaillant launch the ecoTEC exclusive with Green iQ technology, to deliver the highest performing and most efficient boiler on the market.
Vaillant sets the standard for remote monitoring and heating control with their on-line communication system vrnetDialog. For the first time it is possible to monitor and adjust a heating system from afar.
Vaillant Group opened it's UK sales and production site in Belper, Derbyshire as part of the company's transformation into an international enterprise.
Vaillant launches it's first condensing appliance, the Thermoblock ecoTEC. Condensing technology is more energy efficient with less emissions than conventional heating technology.
Vaillant offers the first room-air independent wall-hung boiler with a fan.The room where the boiler is hanging no longer requires continuous positive ventilation and the oxygen required for combustion is drawn in from outside.
Vaillant's 'Combi-Geyser VCW 20' combines heating and hot water supply in a single unit - the first of its kind. An innovation which the sector continues to use today.
Vaillant develops a central heating boiler that allows heating in every room in a house from a central location through room radiators.
Johann Vaillant adopts the 'Easter bunny in an egg' as the trademark for Vaillant. This makes him one of the leaders of branded products in the German consumer goods industry.
Founder, Johann Vaillant sets up his first workshop for installation projects at just 23 years old. A newspaper in Remscheid that he has 'established himself as a coppersmith and pump manufacturer'.
