ecoTEC pro vs. ecoTEC plus with IoniDetect

Vaillant offers condensing boilers with instantaneous hot water heating in two product ranges:

ecoTEC pro (VUW 236/5-3) – a standard, more affordable range, a reliable solution for an apartment or house with one bathroom.
ecoTEC plus with IoniDetect (VUW 26CS/1-5) – a higher-end range with IoniDetect technology, which continuously monitors combustion quality directly in the flame using ionization and fine-tunes the combustion process accordingly. In practice, this means more stable and efficient burner operation regardless of fluctuations in gas quality or other external influences.

Which model to choose

If you are looking for a proven, more affordable choice without compromising on quality, ecoTEC pro is a reliable choice for a typical apartment or house with one bathroom. If you value a more technologically advanced solution with continuous combustion monitoring and are willing to pay extra for it, choose ecoTEC plus with IoniDetect.
