Highly efficient heating

A fast and efficient heating process is a major characteristic of Viessmann VITOWELL comfort cylinder heaters. Every component has been designed with utmost precision: The heating element lies at the very bottom of the tank to assure that all tank water is completely heated. A cold water inlet pipe deflector has been included to stratify the cold water to the bottom part. The water-outlet pipe positioned at the top of the tank withdraws hot water from the very top. The thermostat has been positioned in a way that it provides a reliable temperature measurement at the right point.


Fits everywhere, vertically or horizontally

VITOWELL comfort cylinders come with both vertical and horizontal installation versions, depending on the space at the point of installation.
