Leen and Koen Wildemeersch from Aalter, Belgium

Leen and Koen Wildemeersch installed a flexoTHERM brine/water heat pump with the multiMATIC 700 system control and combined it with a 400-litre geoSTOR hot water storage.

Our installation technician recommended a product with the Green iQ label. After comparing it with other products, we realised it combined all the features that are important to us. It’s eco-friendly and efficient, plus we can control the heating system using an app even when we’re not at home. Since we’ve had the installation, we look at each other every single day and are so happy knowing that the house and heating system are a perfect match for us.

Petar Jakić from Zagreb, Croatia

Petar Jakić and his family have an ecoTEC plus condensing boiler and a calorMATIC 370.

When I’m on a business trip it’s very important for me that my wife and children have everything they need to be safe. I don’t want any worries. I chose Vaillant because it’s reliable, good quality and hassle-free, and it always delivers what we need.

Jan van Marion from Oostvoorne, Netherlands

Jan van Marion installed a geoTHERM heat pump and an allSTOR buffer storage with solar panels.

I was born in Oostvoorne and I still live here together with my family. It has always been my dream to run a restaurant that is surrounded by nature. We could not resist when we had the opportunity to build one right here. The energy concept of the building was very important to us. Eventually, we found the right system through an installer from our village who recommended Vaillant. We now have a system that works perfectly and which we are happy with: it’s good for the environment, good for us, and ultimately good for the durability of our company.

Valerio de Pretto from Venice, Italy

In the seventies most of the heating appliances installed around here in Venice were Vaillant boilers. That was because of poor electric grid connections. Today this problem no longer exists, which means that customers can now choose to install whatever heating brand they want. But they still choose to install Vaillant products because they are reliable and of very high quality.

Valerio de Pretto works for Vaillant as a service technician. Find out more about Vaillant.

Kurt and Lisa Zügner from Altusried, Germany

In their home, Kurt and Lisa Zügner installed an SOFC fuel cell along with a gas condensing boiler.

Vaillant breaks new ground – they have the courage to be innovative and always search for the best solution. This is what we believe in. I have been an engineer in supply technology for 20 years, and I have known Vaillant for all this time. They have been a reliable partner throughout the years.

Pan Desheng from Shanghai, China

Pan Desheng and his family have a turboTEC plus non-condensing boiler.

My family is the most important thing in my life. That’s why our house is much more important to me than our car. At home everything works really well, which is why my wife and I are as happy together as on our first day. Our home is like an island for us. Why do we chose Vaillant? One day, we went to visit our friends and found that the rooms of their home were surprisingly warm even on the coldest of days. The same friend then recommended Vaillant heating systems to me.

Daniel Klages from Solingen, Germany

The light tower is heated with a geoTHERM brine/water heat pump.

When planning the light tower, it was vital for us not to create anything with a short-term effect to show-off, but something substantial and reliable. At the same time, it wasn't supposed to just look like something special from the outside. Hence we naturally integrated our vision into every aspect of the building. To this day, we are convinced that our Vaillant heat pump – an important part of the concept – is the best solution for efficient and sustainable energy production for the light tower.

Lilia Scattolin from Spinea, Italy

Lilia Scattolin and her family decided for the auroCOMPACT. condensing boiler, which uses solar energy for maximum sustainability in an all-in-one system.

We don’t like to waste energy, and we don't want to consume more limited resources than necessary. For these reasons, we use a system with solar collectors to support the production of hot water. That’s a real solution.

Tao Jun from Shangai, China

We lived in Germany for more than ten years, but we came back because Shanghai is our home. In Germany we fell in love with a lot of things, such as Bratwurst, bread and beer – and of course the conscientious work of German engineers. That’s why we installed a Vaillant product in our home. Our little piece of Germany.

Tao Jun and his wife believe in German quality. But where does this quality come from? Take a look at Vaillant's history and Vaillant’s plans for the future!

Dirk van Stappen from Vianen, the Netherlands

Dirk van Stappen upgraded his house with a brand-new, highly efficient Vaillant ecoTEC plus condensing boiler.

I moved into my house 30 years ago. At that time, the building owner chose a Vaillant heating system. The boiler did a good job for 30 years, and I never had any problems with it. That’s why there is no doubt that I would choose a Vaillant boiler again.

Family Hanfland from Solingen, Germany

Gesine and Sven Hanfland believe in efficiency and sustainability, and in their Green iQ heater ecoTEC exclusive with their 800-litre allSTOR storage tank.

Efficiency is key for me. I am completely sold on the merits of the ecoTEC exclusive, which is why we also installed the device at home. I use the app to turn the heating back on when we’re on our way back from our holiday. I can also set a timer to turn the heating on and off. Being able to do all this via the app is even more convenient than using the control unit.

Edvard Ilešič and Petra Markotić from Ptuji, Slovenia

Edvard and Petra installed Vaillant's flexoTHERM exclusvie heat pump to make their house fit for the future.

When a friend recommends something, we trust their advice. Before we had a heat pump, we had had to get up very early to fire up the oven. Now everything is operated at the press of a button and we have more family time. We wanted the best quality and we found it in Vaillant.

Jure Jošt from Prebold, Slovenia

Vaillant's Green iQ heat pump flexoTHERM exlusive, with it's outdoor unit aroCOLLECT, fits perfectly to Jures sustainable lifestyle.

I am interested in future-oriented heating systems and Vaillant offers the best quality in the Slovenian market. The Green iQ products are very efficient and also sustainable. That’s a good combination. We intentionally chose to install the outdoor unit where people could see it from the street. We are proud of our heating system. Why should we keep it hidden from our neighbours?
