Heat pumps use environmental heat directly for heating - a resource that is freely available in the air, groundwater and the ground at any time. In addition to environmental heat, electricity is required. If this is green electricity from a photovoltaic system, then the heat generation works without the use of fossil fuels, emission-free and almost climate-neutral.

At Vaillant, we use a very environmentally friendly alternative to traditional refrigerants in our heat pumps. In our aroTHERM plus we are using the natural refrigerant R290 for the first time. The special thing about R290 is the immensely low global warming potential. The refrigerant also allows the aroTHERM plus to be operated with higher flow temperatures. This means that the heat pump can also be used for existing properties.

Many heating systems in Europe are not efficient enough. For example, in Germany 60% are and therefore offer huge potential for saving CO₂. There is still a long way to go before we can only fall back on CO₂-free systems for heat generation. Switching from a condensing to non-condensing boiler results in approx. 30% energy savings. And modernizing old gas systems with more efficient condensing technology also helps the climate - because every replacement counts!

The gas infrastructure will also be important for climate protection in the medium and long term. It becomes particularly interesting when hydrogen is added as a so-called green gas. We were able to successfully test admixtures of up to 30 percent in our laboratories - this proportion will increase even further in the future. In this way we can offer our customers the comfort they are used to, but much more sustainably.

In addition to the use of energy-saving technologies, our households have further energy-saving potential that everyone can exploit: optimized consumption through intelligently networked and coordinated systems. Because the heating system is often not optimized to the needs of the user. Thanks to the simple and intuitive control, e.g. via an app, the user can make settings at any time and from any location and thus heat more efficiently. What sounds like a dream of the future is already possible today.

There are also many advantages for the skilled craftsman: They can remotely access the networked system without contact and no longer have to be on site at the customer's to analyze the device data. We support the specialist trade with a wide range of services and products for predictive remote analysis and maintenance. In the future, we will enable even better service with increasingly intelligent systems.
