Key Benefits

Innovative Advanced Acoustic Design

The outdoor unit for the Vitocal 222-A follows the Advanced Acoustic Design (AAD), taking into account structural acoustic specifications. The result is hardly audible. 

The high-quality and sound -optimised fan in combination with an intelligent speed control contributes significantly to the reduction of airborne noise at full and partial load operation. Low frequencies are largely avoided, which would otherwise be perceived as disturbing with conventional heat pumps.

Particularly quiet

With a sound pressure level of only 35 dB(A) at a distance of three metres (night mode), the outdoor unit (with a fan) of the new Vitocal 222-A air/water heat pump compact unit is one of the quietest units of this type. Installation close to the neighbouring property or in densely built-up areas, such as terraced housing estates, is therefore no problem.

EHPA seal of approval

The EHPA seal of approval serves as proof of the COP (Coefficient of Performance) for funding under the market incentive programme.

The German EHPA Quality Seal Commission certifies that the Viessmann Vitocal 222-A heat pump meets the requirements of the EHPA quality seal regulations.

Vitotronic 200 with WiFi option

The heat pumps can even be controlled from anywhere using the Vitotronic 200 control unit via the Vitoconnect web interface (accessory) and the free ViCare app.

Stay connected with Vitoconnect 100

The Vitoconnect 100 interface is required for operation via app. Retrofitting for earlier heat pumps in the Vitocal series (built in 2010 or later) 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". In accordance with this philosophy, Viessmann does not simply supply individual heating equipment components that meet the high Viessmann standards for quality, reliability and effectiveness. In addition, all products are part of a matching overall concept, where all components complement one another. After all, only perfect interaction between all system parts 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.

Vitocal 222-A air/water heat pump

The Vitocal 222-A monobloc heat pump uses the heat contained in the outside air in an environmentally friendly and cost-effective manner. It can heat and cool. The compact unit has an integrated 220 litre DHW cylinder.

Compact monobloc outdoor units

The new outdoor units in a timeless design are very pleasing to the eye. The units with one or two fans are developed and manufactured in-house. In addition to excellent performance levels, they have exceptional workmanship and product quality.

Fast installation time 

The compact, wall-mounted indoor unit with hydraulics and control is quiet and can be installed close to the living area. The connecting pipes to the outdoor unit are filled with water, for the installation of which the tradesman does not require F-gas certification. Due to the high degree of pre-installed components and matching accessories, the Vitocal 222-A can be installed in a very short time.

High level of DHW convenience

The Vitocal 222-A is equipped with a large integrated 220-litre DHW cylinder and the newly developed inflow device ensures very good layering, allowing a high tap volume of up to 290 litres (at 40°C).
