The Vitocal 350-A air source heat pump with a rated heating output from 12.7 to 20.6 kW is particularly suitable for modernisation projects. Thanks to enhanced vapour injection in the compression process (EVI cycle), flow temperatures as high as 65 °C can be achieved –– even at wintry outside temperatures. This means the Vitocal 350-A is also highly suitable for installation in older heating systems with radiators. To raise efficiency, we recommend replacing individual radiators with ultra-low temperature ones.
The Vitotronic 200 control unit has an integral cascade function for up to five air source heat pumps. Heating outputs of up to 92.5 kW are therefore possible to cover high heat demands.
The Vitocal 350‑A is equipped with the Vitotronic control system, featuring a clear text and graphical display for precise control of heating and DHW operation.
Supports remote access via Vitocom 100 / Vitocom 300, enabling system monitoring, diagnostics, and control from external locations.
When combined with Vitoconnect, the system can be operated through the ViCare app, allowing convenient control via smartphone or tablet.

The Vitocal 350‑A is particularly suitable for modernisation projects, as it can deliver high flow temperatures compatible with existing radiator systems.
The unit can achieve flow temperatures up to 65 °C, even in cold outdoor conditions, making it ideal for high-temperature heating requirements.
It offers a coefficient of performance (COP) of up to 4.0 (A7/W35), meaning it produces significantly more heat energy than the electrical energy it consumes.
Yes. Up to five Vitocal 350‑A units can be connected in a cascade system, providing a total output of up to 92.5 kW.
