The powerful Vitocal 350-G brine/water heat pump is one of the quietest heat generators of its kind thanks to its low vibration design.
Where heat demand is even higher, the Vitocal 350-G can be operated in two-stage mode with an additional heat pump of the same type, or with a Vitocal 300-G in a master/slave system, and can then provide an output of up to 84.6 kW. At an early stage when planning the system, this configuration allows for optimum matching of the heat pumps to the building in question.
The ViCare app provides intuitive heating control. Green for go – the user can see at a glance in the app whether their heating system is working as it should.
ViGuide is an app for trade partners. It has numerous functions for monitoring and controlling systems in both detached houses and apartment buildings and provides rapid access to Technical Service.
The Vitoconnect is the interface between boiler and app – the prerequisite for heating system operation via smartphone and tablet. It also provides remote system maintenance capability for contractors using the Vitoguide app.
Viessmann uses the convenient Vitotronic 200 control unit to ensure standardised operation of all its heat generators. Its many functions include menu-guided operation, an integral diagnostic system, control of the instantaneous heating water heater and an additional (existing) oil or gas boiler, and of course, the natural and active cooling functions.
Furthermore, the Vitotronic 200 is capable of communicating and, via the Vitocom 300 communication module, allows the heat pump system to be set up, monitored and optimised over the internet with the Vitotrol app on a smartphone or tablet.

This heat pump requires a ground-based energy source, such as:
Horizontal ground collectors
Vertical boreholes (geothermal probes)
Yes, the Vitocal 350‑G can provide:
Heating in winter
Passive or active cooling in summer (depending on system setup)
It can be used in retrofits, but users should note:
Works best with well-insulated homes
May require larger radiators or low-temperature systems
The system generally requires low maintenance, but users should plan:
Annual inspection by a technician
Checking circulation pumps and heat exchanger
Monitoring system pressure
Compared to fossil fuel systems, maintenance is simpler and less frequent.
