How old is my Viessmann?
A serial number alone may not establish the age of your Viessmann equipment. Look for a manufacture date on the rating label, then check original documents or contact the manufacturer if the date is missing.
We recognize Viessmann. We’re still building its age decoder.
You can still scan the data plate to extract the brand, model and serial and check available recall information. We won’t guess the manufacture date.
