Warranty information
In order for your boiler to qualify for a free of charge manufacturer’s guarantee period longer than the minimum 2 year period set out in the standard Terms and Conditions of Sale, your installation must be registered with Viessmann within 30 days. You or your installer can register the installation, using the online or offline options available. The free of charge voluntary guarantee period varies by product, please see below for the period that applies at the time of purchase.
For an extended guarantee, which is offered on some models as a purchase option, your installer must register your installation on the Viessmann Installer Portal for installations in Great Britain.
For installations in Eire and Northern Ireland, your installer must register your installation here.
