Vitocal 222-A

The Vitocal 222-A monobloc heat pump makes environmentally responsible and cost effective use of the latent heat in the outdoor air. It can provide heating and cooling. This compact appliance includes an integral 220 litre DHW cylinder.

These new outdoor units in their timeless design are very easy on the eye. These appliances with one or two fans are designed and manufactured in-house. Consequently, they offer very good performance data, an excellent finish and superb product quality.

The acoustic properties of the outdoor units for the Vitocal 222-A comply with advanced acoustic design (AAD) specifications. The result is barely audible. In conjunction with intelligent speed control, the high grade, sound-optimised fan significantly contributes to reducing airborne noise in full and partial load operation. Low frequencies that are generally perceived as a nuisance in conventional heat pumps are largely prevented.

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 compact air source heat pump is one of the quietest appliances of its kind. Installation close to a neighbouring property or in densely built-up areas, such as terraced housing, is therefore no problem. You can also find detailed information about this in the section on air source heat pumps and sound.

All components installed in the Vitocal 222-A with DHW cylinder are optimised to work together. The result is high efficiency, which is reflected in the low running costs. Expressed in figures, the Vitocal 222-A achieves a COP (coefficient of performance) of up to 5.0 at 7.0 °C outside temperature and 35.0 °C water temperature in accordance with EN 14511. Even at 2.0 °C outside temperature and 35.0 °C water temperature, the COP is still 4.1.

Even with the integral 220 litre DHW cylinder, the indoor unit of the Vitocal 222-A is extremely compact. Its dimensions (depth x width x height) of 681 x 600 x 1874 mm allow straightforward installation in almost any room. If the Vitocal 222-A is extended to include a ventilation unit such as the Vitovent 300-W or Vitovent 300-F, there is a further advantage: the ventilation unit can be operated with the Vitotronic 200 heat pump control unit that is already fitted. The space required for both systems is thus reduced to a minimum. Detailed information about this subject can be found in the section on mechanical ventilation.

The simple and intuitive user interface of the Vitotronic control unit gives you an overview of your heating system in just a few steps. The control system is also web-enabled thanks to the Vitoconnect interface (accessory) and the free ViCare app. This not only allows you to control your system from wherever you are –– remote maintenance by an authorised contractor is also possible, ensuring optimum operation.
