Heat exchanger innovation

From the biferral composite heating surface to the Inox-Radial heat exchanger

High standards

Viessmann feels a deep seated obligation to employ highly efficient technology that does everything possible to protect the environment. With efficiency levels of up to 98 percent, our heating systems reach the limits of that which is technically possible. We set the same high standards for energy efficiency in relation to electricity supply, refrigeration technology and advanced steam systems. Continuous improvement is our goal.


The foundations for top quality are laid down at the development stage.
