Vitocal 222-A

The compact air source heat pump in the monobloc design ensures a high level of DHW convenience with its integrated 220 litre DHW cylinder.

  • Rated heating output: 3.8 to 11.6 kW
  • Integral DHW cylinder
  • Heating and cooling in one
  • Highest efficiency in the smallest of spaces

Vitocal 222-A

The Vitocal 222-A air source heat pump is characterised by its separation into an indoor and an outdoor unit, with water-carrying connection lines. In addition to the control technology and high efficiency circulation pump, an enamelled DHW cylinder with a capacity of 220 litres is also installed in the compact indoor unit.

The newly developed inlet system ensures very good stratification, which allows a high draw-off volume of up to 290 litres (at 40 °C). The DHW demand can therefore be met with no difficulty. The compact air source heat pump is also set up to make optimum use of self-generated power from photovoltaic systems. System owners are therefore ideally equipped for environmentally responsible and futureproof heating with renewable energies.

A crucial advantage for system owners is the barely audible operation of the heat pump. In addition, the Vitocal 222-A monobloc air source heat pump can be used for both conventional heating and cooling in the warmer months of the year. This is made possible by the circuit reversal function.
