We, in the Viessmann Group companies, take the protection of your personal data very seriously and adhere strictly to data protection regulations. Personal data is only recorded on our websites and when using our apps to the absolute minimum extent necessary.

It applies to all websites and apps under Viessmann's responsibility. Viessmann websites and apps may include links to the websites of other suppliers, but this data protection statement does not extend to such sites/apps.
