About Viessmann

Viessmann, also known as Viessmann Climate Solutions, is a German heating technology company founded in 1917. Headquartered in Allendorf, Germany, it produces heating equipment and systems. Official site: viessmann.de.
Viessmann builds heating systems and connected climate solutions, and its online services let you control boilers and heat pumps from an app or browser. When those services slow down or the login stops working, it is hard to tell whether the problem sits with the platform or with your own setup. This page tracks reported problems with Viessmann's website, login, and related online services so you can see the current picture at a glance.
Viessmann is a German heating technology company founded in 1917, headquartered in Allendorf. Besides its heating equipment, it runs web services and a connected app that let customers monitor and adjust their heating systems remotely. The issues most often reported here involve the online login, the website itself, and connected features that stop syncing with a boiler or heat pump. An app that shows stale readings is common during server-side trouble. If something looks broken, first check that your home internet is up and that your heating system has power. Then try logging in again from a different browser or the app. If other users are reporting the same thing, the fault is likely on Viessmann's side and waiting is usually the best move.

Why can't I log in to my Viessmann account?

Check your username and password first, then confirm your internet connection is stable. If the login page itself fails to load or rejects correct credentials, the service may be having a temporary problem. Wait a short while and try again.

My app shows outdated heating data. Is something wrong?

Stale readings usually mean the app cannot reach the servers or your heating system has lost its internet connection. Check that the system is powered on and connected to your network. If the connection is fine but data still won't update, the issue is likely on the service side.
