Warning about scamming calls 

Recently, there has been an increase in scam calls or door-to-door visits where unknown people have claimed to be employees of Viessmann Climate Solutions. We take this issue very seriously and want to prevent people from being victimized by raising awareness. 

The scam is usually carried out by contacting people by telephone or personally at the door. The aim of the scammers is to obtain personal data or money. We are aware of the following methods:

  • The callers imply that you are interested in a Viessmann Climate Solutions solution and would like to arrange an on-site appointment for advice or an on-site appointment for concluding a contract – with assurance of sufficient available equity.
  • The caller claims that a Viessmann Climate Solutions solution has already been purchased and requests a partial payment in advance so that the system can be installed.
  • The person at the door claims to be a Viessmann employee and offers Viessmann climate solutions at particularly favorable prices that are not in line with market conditions. The aim is to obtain personal data or an advance payment in cash.

Please note the following to protect your data: 

  • Check authenticity: Our employees will not ask you for sensitive, personal or financial information at a first touchpoint. 
  • Check the phone number: Scammers often use fake phone numbers. So be aware and, if in doubt, hang up and return the call.
  • Security measure: Never give out confidential information over the phone or at the front door, especially if you have doubts about the authenticity of the person.

If you have any concerns or receive suspicious calls relating to Viessmann Climate Solutions, please contact datenschutz@viessmann-climatesolutions.com.

We recommend affected people to contact the local police department if they believe they have evidence of a scam or have already been a victim.
