You can revoke your consent to the use of the data provided via the contact form at any time. Please contact:  dataprotection-uk@viessmann.com

II. Provisions for commercial users

This part of the data protection provisions applies only to commercial users such as contractors, industrial businesses, local authorities, commercial enterprises, planners, architects, etc. and only to the extent that these users provide personal data of contact persons on our websites and in our apps for the conclusion and implementation of contracts in accordance with point (b), Art. 6(1) GDPR.

Personal data is collected and processed by Viessmann for the following purposes:

  • Handling customer enquiries
  • Forwarding information to customers making requests
  • Displaying information in Viessmann trade directories (e.g. local trade partner search at www.viessmann.de, installer search at heizung.de)

If you have provided us with personal data, we only use this to answer your queries, to process contracts concluded with you, for technical administration, for logging in and in the services provided on the respective web pages or apps.

Saved personal data is deleted if you withdraw your consent to its storage, if the information is no longer required in order to fulfil the purpose intended by its storage, or if its storage is not permissible for other legal reasons. To do so, please send an email to widerruf@viessmann.com. Your data will then be deleted or, if the data is still required for verification, billing and/or accounting purposes, will continue to be stored for these purposes.

For other personal data processed within the context of delivery and service in accordance with point (b), Art. 6(1), the data protection provisions in the respective General Terms and Conditions of Sale apply.

Disclosure of personal and company data

For the provision of services by third parties or services offered by partners (these are listed within the respective consent text), we forward, with your consent, the personal and company data entered by you to them, primarily for the purpose of establishing contact.

III. Provisions for applicants

This part of the data protection provisions applies to applicants responding to job advertisements at the  Viessmann Climate Solutions SE or third party companies to which Viessmann provides a platform or partner programme for job advertisements/placement. This applies only insofar as these applicants transmit personal data to Viessmann as part of the application process, e.g. an application in paper format, by email, contact forms with attachments or portals operated by Viessmann (e.g. the Apprentice Portal) or the use of electronic job boards operated by third parties in accordance with the requisite content, also in accordance with additional local/provincial specifications. Application documents submitted on paper are scanned and stored in our systems, after which the paper is disposed of by certified service providers in compliance with data protection law.

We will use your personal data solely to process your application and/or as part of talent relationship management and on the basis of your consent to this Privacy Policy.   The processing of your application also includes, if required, the use of your data for the purpose of contacting you by email and/or post and/or telephone and, if applicable (e.g. Apprentice Portal), also the forwarding of the application documents to third party companies. Those responsible for recruitment and HR at Viessmann Climate Solutions SE, the respective company as well as supervisors or others responsible for recruitment in the division in which the position is advertised have access to your documents. Further processing is carried out anonymously for the purpose of gauging the success of job placements and the technical application channels used, as well as the skills imparted by applicants – also anonymously.

With the exception of the Apprentice Portal, the data is processed using systems from Greenhouse Software, Inc. a company based in the USA. To this end,  Viessmann Climate Solutions SE has concluded a contract with Greenhouse Software, Inc. based on the EU standard data protection clauses in accordance with Art.  46 GDPR.

The applicant's personal data is deleted automatically after 4 months at the earliest, but no later than after 6 months, starting at the point in time at which the applicant is informed that the position will not be occupied by him/her and provided that there are no further statutory requirements against deletion. The time limit is based on the requirements of the German Anti-Discrimination Act (AGG).

On acceptance into the Talent Relationship Management Program, your data will be stored in our system for up to 365 days so that you can have advance consideration for future job vacancies. In this regard, we will use the data you have provided to contact you by email and/or post and/or telephone. Only if you have granted your express consent in response to our enquiry will your data continue to be stored in our system after the end of this period in order that you can be considered for other future job vacancies.

If you register for the Viessmann Job Alert on the Viessmann career pages or other job portals operated by Viessmann, your email address will be used to send you job offers until you unsubscribe from this Job Alert. When you register for the Job Alert, we store your email address, your IP address and the date of registration. This storage serves solely to provide evidence in the event of a third party misusing an email address and registering to receive the Job Alert without the knowledge of the authorised person. You can revoke your consent to receive the Job Alert at any time with future effect. If you no longer wish to receive the Job Alert, you can unsubscribe at any time by clicking on the unsubscribe link in the Job Alert or by sending an email to  recruitment-uk@viessmann.com.

If sending application documents in paper format without reference to job advertisements in our electronic formats, e.g. as a speculative application, you will receive a summary of this Privacy Policy along with an acknowledgement of receipt of your communication or, at the latest, in the event of a rejection by us.

IV. General information and regulations for Viessmann websites and apps

These provisions apply in addition to the provisions for private users and the provisions for business users for Viessmann websites and apps. Some of our apps have their own additional data protection statements. The Viessmann Apps ViCare and Vitotrol Plus data protection statement can be found under the following link:


Data processing by accessing our Internet pages and using our apps

Viessmann automatically collects and stores information in its server log files that your browser or app transmits to us. Viessmann cannot assign this data to individual persons. This data is not merged with other data sources. These are:

  • Browser type/ version

  • Operating system used

  • Referrer URL (the previously visited page)

  • Host name of the accessing computer (IP addresses v4 and v6)

  • Time of the server request

The IP address is the globally valid identification of your computer at the time of allocation by your Internet provider and consists, in its currently most common form (IPv4), of four blocks of digits separated by dots. In most cases, as a private user, you will not use a constant IP address, as this is only temporarily assigned to you by your provider (so-called "dynamic IP address"). With permanently assigned IP addresses (so-called "static IP addresses"), a clear assignment of user data via this feature is technically easy.

The mentioned data will be processed by us for the following purposes:

  • Ensuring a smooth connection to the website

  • Ensuring comfortable use of the aforementioned website

  • Evaluation of system security and system stability

  • For further administrative and statistical purposes

The personal data of the server log files is processed on the basis of Art. 6 para. 1 lit. f GDPR. This authorisation allows the processing of personal data in the "legitimate interest" of the person responsible, provided that your fundamental rights, freedoms or interests do not prevail. Our legitimate interest is in the easier administration and the ability to detect and track hacking. You can object to this data processing at any time if there are reasons which exist in your particular situation and which contradict the data processing. All you need to do is send an e-mail to the data protection officer. Our legitimate interest follows from the purposes listed above for data collection. Under no circumstances do we use the data collected for the purpose of drawing conclusions about you personally.

The server log files with the above data are automatically deleted after 30 days or anonymised if used for statistics. We reserve the right to store the server log files for longer if facts exist which suggest the assumption of unauthorised access (such as an attempt at hacking or a so-called DDOS attack).


Data processing for access to our websites and apps - "Viessmann Account"

Viessmann uses a central identity and access management system ("IAM") in addition to conventional login functions (e.g. user ID and password) for granting, changing and deleting access and access authorisations for websites and apps that are not public or not freely usable. For this purpose, the following personal data will be processed from you:

  • E-mail address
  • Password
  • Website / app used with last time stamp
  • User role(s)
  • Timestamp of last successful login
  • First name, last name and other data (depending on the website / app used)
  • Mobile/telephone number (for 2-factor authentication)

The above data is processed by us for the following purposes:

  • Creation of the "Viessmann Account"
  • Creation and management of access rights to apps and websites
  • Creation and administration of role-based access rights within apps and websites
  • Checking and display of authorisations by/for the respective responsible functions for the individual websites and apps at Viessmann
  • Communication of information on the website and app used (e.g. changes, error messages, innovations, etc.)
  • Creation and usage of aggregated (“anonymized”) key figures on the use of websites and apps

Depending on the website or app used, permission to process your personal data is granted for the following reasons

  • The fulfilment of a contract with you in accordance with GDPR Art. 6 Para. 1 lit b, the subject of which also includes the use of Viessmann websites or apps,
  • your consent in accordance with GDPR Art. 6 Para. 1 lit a if you are explicitly asked for this or
  • in our legitimate interest according to GDPR Art. 6 Para. 1 lit. f.

The last-mentioned permission allows the processing of personal data within the framework of the "legitimate interest" of the controller, insofar as your fundamental rights, freedoms or interests do not prevail. Our legitimate interest is the efficient administration of access and access rights and the protection of the websites and apps as well as the data processed there against unauthorised use (e.g. disclosure, modification, deletion). You can object to this data processing at any time if there are reasons relating to your particular situation that speak against the data processing. An e-mail to the data protection officer is sufficient for this purpose. Before objecting, please check whether you cannot delete the user account yourself. Some user roles, especially those based on consent, also allow you to delete your personal data yourself as part of a self-service. In no case do we use the collected data for the purpose of drawing further conclusions about your person or creating profiles.

The above-mentioned data will be automatically deleted or, in the case of use for statistics, anonymised if your user account is inactive for longer than 360 days (last time stamp of successful login or use of website or APP). You will receive corresponding information from us before this period expires. We reserve the right to store personal data for a longer period of time if this results from legal or contractual reasons or if facts exist that suggest the assumption of unauthorised access.


Linking to external websites

This data protection statement applies exclusively to the Viessmann websites and apps. These may contain links to third-party websites. This data protection statement does not extend to these. If you leave the Viessmann websites and apps in order to visit the services of a third-party provider, we recommend that you also carefully read this provider's data protection statement.

Information on cookies and the use of analysis tools

The processing of personal data through cookies and analysis tools (Google Analytics and Google Tag Manager, Google Adwords Conversion Tracking, Third-Party-Cookies, Re-Targeting-Technologies, Google Remarketing, VWO, Wisepops, Facebook Remarketing and Inspectlet) is based on Art. 6 Para. 1 lit. f GDPR. This authorisation allows the processing of personal data in the "legitimate interest" of the person responsible, provided that your fundamental rights, freedoms or interests do not prevail. Our legitimate interest is to analyse the use of our website.

We support the processing of personal data by Google AdWords (list all retargeting technologies) is based on Art. 6 Para. 1 lit. f GDPR. This authorisation allows the processing of personal data in the"legitimate interest" of the person responsible, provided that your fundamental rights, freedoms or interests do not prevail. Our legitimate interest is in the personalised display of targeted advertising and the statistical analysis of the effectiveness of advertising (e.g. determining how many clicks on an advertising banner have led to a purchase from our website).

Viessmann uses so-called cookies in several places on its websites and in its apps. They serve to make our website more user-friendly, effective and secure. Cookies are small text files that are stored on your computer and saved by your browser. Most of the cookies we use are so-called "session cookies". They are automatically deleted at the end of your visit. Cookies do not cause any damage to your computer and do not contain any viruses.

Viessmann also uses analysis tools for this purpose, such as Web Trends or Google Tag Manager (Firebase). The data provided and used is collected and stored completely anonymously. This data may also be stored outside the United Kingdom or the European Union.

When implementing and using analysis tools and tracking technologies, we make personal data anonymous as quickly as possible either on the part of the provider, regulated by appropriate contracts, or within the scope of our first use, so that the right to information on your part cannot be exercised on all technologies listed below.

You can prevent the transmission of such data by making the appropriate settings in your browser, app or the operating system environment (iOS, Android). However, this may lead to problems in calling up, operating or functionality of the content or service offered.


Viessmann makes use of a number of advertising partners who help to make the Internet offer and the websites more interesting for you. For this reason, cookies from partner companies are also stored on your hard drive when you visit the websites. These are temporary/permanent cookies that are automatically deleted after the specified time. These temporary or permanent cookies (lifetime 14 days to 10 years) are stored on your hard disk and delete themselves after the specified time. The cookies of our partner companies also only contain pseudonymous, usually even anonymous data. This includes, for example, data on which products you have looked at, whether something was purchased, which products were searched for, and so on.

Some of our advertising partners collect information about which pages you have visited before or which products you have been interested in, for example, in order to be able to show you the advertising that best suits your interests. This pseudonymous data will never be combined with your personal data. Their sole purpose is to enable our advertising partners to address you with advertising that might actually be of interest to you.

Re-Targeting Technologies

Our websites use so-called re-targeting technologies. We use these technologies to make our website more interesting for you. This technology makes it possible to address Internet users who are already interested in our products with advertising on the websites of our partners. We are convinced that the insertion of personalised, interest-related advertising is generally more interesting for the Internet user than advertising that has no such personal reference. The insertion of these advertising materials on the pages of our partners is based on cookie technology and an analysis of the previous user behaviour. This form of advertising is completely pseudonymous. No user profiles are merged with your personal data.

By using our site, you consent to the use of so-called cookies and thus to the collection, storage and use of your user data. Furthermore, your data is stored in cookies beyond the end of the browser session, so that it can be called up again the next time you visit the website, for example. You can revoke this consent at any time with future effect by refusing to accept cookies in your browser settings.

You can find your current settings on the page you are using and there in the footer "Cookie & Tracking".
