The Vaillant ecoTEC exclusive is an intelligent gas condensing boiler with very high domestic hot water comfort. The ecoTEC exclusive uses a brand-new monitoring electrode that ensures optimized combustion. This unique combustion technology guarantees that energy is always used as efficiently as possible, while emissions remain as low as possible.
Compact wall-mounted boiler with intuitive controls
The design of the ecoTEC exclusive is specifically developed to seamlessly integrate even into the smallest spaces. It is suitable for both large homes and smaller apartments. Additionally, we have enhanced the user interface with a user-friendly touch screen display.
Independent of varying gas qualities
Thanks to intelligent IoniDetect technology, the boiler automatically adjusts to different gas qualities. This ensures the highest energy efficiency and the lowest heating costs. Moreover, the adaptability results in stable and long-lasting operation of the boiler with minimal maintenance efforts. The system operates automatically and always provides the highest comfort.
