===Remote Deactivation of LANCard (March ''2025'')===
In March 2025, customers were informed that the integrated network interface that was purchased with the heating solution would be deactivated and would cease to function, citing that the warranty period had elapsed on the affected products. Affected customers should buy a different interface for remote control called a "Vitoconnect", which does not offer equivalent functionality. Viessmann claimed that the speed of the LAN interface was insufficient, while the proposed new device relies on signnificantly slower and less reliable infrared communication and WiFi.<ref>{{Cite web |first=CustomerCareChris |date=2025-03-28 |title=Informationen zum Ende der integrierten LANCard |url=https://community.viessmann.de/t5/Konnektivitaet/Informationen-zum-Ende-der-integrierten-LANCard/m-p/533312 |access-date=2025-04-11 |website=Viessmann Climate Solutions Community [German]}}</ref>
===Making users buy back their own data (''????'')===
Kuketz Forum user Galaga cites conversations with their heating technician claiming that Viessmann devices send data to the manufacturer's servers over WiFi at very high frequency. Users can then see the data inside their apps with an artificially imposed rate limit. If a user wants full access to their data in real time, they have to pay for a subscription service to get access to the status information for devices they legally own and paid for.<ref>{{Cite web |first=Galaga |date=2025-04-07 |title=Sind moderne Heizungen/Wärmepumpen (Mitsubishi) ein Sicherheitsrisiko? |url=https://www.kuketz-forum.de/t/sind-moderne-heizungen-waermepumpen-mitsubishi-ein-sicherheitsrisiko/12078/4 |access-date=2025-04-11 |website=Kuketz Forum [German]}}</ref>

=== Not offering component-level repairs ===
The manufacturer usually does not repair logic boards, but only replaces them when they fail (even if it is just a 5 ct component) at costs of several hundred to a thousand Euros per board, making many repairs unnecessarily cost prohibitive, leading people to replace entire heating installations even when it wouldn't be necessary.
