Intro

Sustainability at Vaillant

Three key innovations driving sustainable heating.

Since 1874, our journey has been driven by a relentless pursuit of innovation, reliability, and efficiency. Our products not only exemplify quality but are also champions of renewable energy, making meaningful strides in climate protection.

Heat pumps
Hydrogen
Smart living

Harnessing the energy of nature.

Heat pumps capture the earth’s free warmth from air, groundwater, and soil. Pair them with green electricity from a photovoltaic system, and you’ve got emission-free, climate-friendly heating.

At Vaillant, we champion eco-friendly alternatives like R290 in our aroTHERM plus heat pump. This natural refrigerant boasts a low global warming potential and supports higher flow temperatures, making it ideal for existing homes.

Check of hydrogen ready boiler

Many European heating systems lag in efficiency, with 60% in Germany alone offering vast CO₂-saving potential. Transitioning from non-condensing to condensing boilers can save approximately 30% energy. Replacing old gas systems with efficient condensing technology is a climate win.

As the gas infrastructure evolves, hydrogen emerges as a promising green gas. We've successfully tested up to 30% hydrogen blends, with more to come, ensuring our customers enjoy familiar comfort, sustainably.

Man talking about the control app with an installer

Connect and control.

Beyond energy-saving technologies, our homes have untapped potential for optimised consumption through intelligently networked systems. Often, heating systems aren't tailored to the user's needs. With simple, intuitive controls, like an app, you can adjust settings anytime, anywhere, ensuring efficient heating.

There are also many benefits for installers. They can remotely access the networked system without needing to be on-site to analyse device data. We support the trade with a range of services and products for predictive remote analysis and maintenance. In the future, even smarter systems will enable even better service.

Cutting-edge innovation

The technology centre: where innovation happens.

Centralising all development activities at the new Johann Vaillant Technology Centre in Remscheid accelerates innovation through short distances, interdisciplinary teams, and effective communication. Our test centre boasts over 230 test stands, with 40 dedicated to heat pumps alone.

Sustainability at the core

Anchoring sustainability: our green compass.

To continue this path and keep focussing on sustainability in the product development process, the 5 Green Rules drawn up by Vaillant are an integral part of our research and development process. They bundle internal and external product requirements, including energy efficiency and longevity, and are systematically summarized in a 5 Green Rules report. In this way, they act as a guide for sustainability in our product development and guarantee it from the very first step.

Energy efficiency: power up, emissions down.
We stand for sustainable and energy-efficient products, innovation, resource protection and low-emission technologies.
Durability: built to last, crafted to care.
We guarantee durable and robust products thanks to the use of high-quality materials. Diligence and precision lie at the heart of our corporate image, and reinforce our high quality standards.
Responsibility: green choices, global impact.
We act responsibly when selecting materials and suppliers, and take an environmentally friendly approach to production and logistics.
Handling: simplicity in every touch.
We make intelligent and user-friendly products that are easy to install and use. That includes intuitive controls, smart home apps and transparent energy monitoring to help users run their appliances more efficiently.
End of life: closing the loop, conserving the earth.
We’re committed to conserving natural resources and eco-friendly disposal of products. We design our products so they can easily be recycled.
