Technologies
Our technologies at a glance
The Vaillant Group develops energy-efficient and innovative products for heating, cooling and hot-water supply. They can support the energy transition in the buildings sector.
The focus of the Vaillant Group is on heat pumps that can cover up to 75 per cent of energy demand with freely available environmental heat. On energy-efficient gas-condensing boiler technology, which also uses the heat energy contained in the flue gas. And on hybrid systems that intelligently combine different technologies and use energy efficiently. The Vaillant Group also offers installers, end customers and housing associations additional benefits with its digital services.
These technologies are being developed at eight sites in Europe and China. The heart of heating-technology development and thus the decarbonisation of the buildings sector beats in the Johann Vaillant Technology Center, the new Vaillant Group research and development centre. Our current and official sustainability activities, targets and measures, can be read in the Climate Transition Plan of the Vaillant Group.

Heat pumps
Heating with heat pumps can support energy-efficient heating. They use the freely available environmental heat from air, water and earth. Only a quarter of the energy required is provided by electricity. When powered by electricity from renewable sources, operational emissions can be significantly reduced.

Gas-condensing boiler technology
Gas-fired condensing boilers are established heating systemsused in a wide range of applications. The use of alternative gaseous energy carriers such as hydrogen or biomethane produced using processes aimed at reducing greenhouse-gas emissions, makes the technology even more efficient. Moreover, gas-fired condensing boilers can be combined with technologies based on renewable energies to form hybrid systems.

Hybrid heating systems
A hybrid heating system is one that combines at least two different heating technologies – mostly those that are powered by renewable energies and/or fossil fuels. Depending on building characteristics and system configuration, hybrid systems can contribute to reducing emissions and energy consumption.

Digital solutions
The Vaillant Group develops digital services for system owners and installing partners, as well as housing associations and property companies. From control of the heating via app, contactless remote monitoring and device diagnostics to management solutions for a larger number of heating systems.
