Vaillant ecoTEC – older boiler and cylinder sets
In this category you will find sets of the Vaillant ecoTEC plus/pro condensing boiler (VU INT range) with a separate VIH hot water cylinder – in R (stationary) and CB (compact, for hanging next to the boiler) versions. This is an older, but still commonly available and serviced generation, offered in several outputs and cylinder volumes (75, 120 and 150 liters), so you can choose a set exactly according to the size of your household.
Frequently Asked Questions
- What is the difference between a VIH R and a VIH CB cylinder? VIH R is a stationary cylinder installed separately, VIH CB is a more compact design intended for hanging directly next to the boiler – the choice depends on the space available in the boiler room.
- Is this set still commonly available? Yes, it is an older, but still sold and fully serviced generation of Vaillant boilers, also suitable as a replacement for an existing installation.
- What cylinder volume should I choose? From 75 liters for a smaller household up to 150 liters for a family house with higher hot water consumption – we're happy to help you choose based on the number of people and draw-off points.
