Key Benefits

Small footprint and easy to handle

The small footprint of this heat pump makes it particularly suitable where space is at a premium – the brine circulation pump, heating circuit pump and 3-way diverter valve are already integrated inside the compact casing.

If required, to simplify the handling and installation of the Vitocal 222-G, hydraulic and electrical plug-in connectors are available, which enable the new refrigerant circuit module to be easily removed from the heat pump and transported separately. Thanks to the flexible connection concept, the heat pump can also be quickly matched to the installation situation on site.

Vitotronic 200 control unit with optional app control

The Vitotronic 200 control unit, with plain text and graphic display, is simple and intuitive to use. Settings can quickly be changed by following the user prompts. 

Control via the internet through the ViCare app on a mobile device is also an option.

Vitoconnect 100 creates the connection

The Vitoconnect 100 interface is required for operation via the app. Retrofitting earlier heat pumps of the Vitocal series (from year of construction 2010) is possible at any time.

ViCare App

The ViCare app enables system users to control their heating system via smartphone. The operating status can be viewed at any time and the contractor whose details have been stored in the app can be contacted quickly and easily if a fault occurs.

A perfect match – System technology

"The whole is greater than the sum of its parts". Following this philosophy, Viessmann supplies more than high quality, reliable and effective heating components. In fact, all products are part of a matching total concept, where all components complement one another. After all, only perfect interaction between all system components can draw out the maximum potential of our innovative leading technology.

Viessmann system technology incorporates everything you need for a reliable and economical heating system: From the Vitotronic control unit with wireless remote control, powerful Vitocell DHW cylinders for the highest DHW convenience, right up to high grade solar thermal systems for cost effective central heating backup.

The Vitocal 222-G compact heat pump

The Vitocal 222-G compact brine/water heat pump is fully equipped with all of the components required for DHW and central heating.

With heating outputs of between 5.8 and 10.4 kW, they are ideal for use in detached houses. Flow temperatures up to 65 °C also enable use with conventional radiators.

The heat pump is an attractively priced alternative to the compact appliance in the 300 series. With its refrigerant circuits with a fixed heating output, in three output sizes, and an electronically controlled expansion valve, it achieves a COP (coefficient of performance) of up to 4.8 (to EN 14511 (5/2018) at B0/W35).

Large DHW cylinder

The Vitocal 222-G compact heat pump offers a high level of DHW convenience thanks to its 220 litre DHW cylinder, which is heated via an internal indirect coil.

Extremely easy to operate

Like all compact appliances, the Vitocal 222-G is also equipped with the extremely user friendly Vitotronic control unit. If in doubt, help is available at the push of a button. The graphic interface will also display heating curves and switching times.

Particularly quiet operation

The casing completely protects the refrigeration module/hydraulic compartment from the outside environment and, in conjunction with the three-dimensional anti-vibration mounts, minimises operating noise. These compact heat pumps are some of the quietest in their category, as they generate a sound power level of only 46 dB(A) (B0/W55).

Heating naturally – naturally cooling as well

The compact heat pumps can provide a pleasant climate in a low energy house, even on hot summer days. The natural cooling function brings cool underground temperatures into the home. For this, the Viessmann NC-Box is required as an accessory.
