Vitocal 222-F: Viessmann - Germany


Compact split air source heat pumps for new build and modernisation, with integral DHW cylinder for a high level of DHW convenience.Take advantage of  extra efficiency gained through heat pump technology.

Split heat pumps are characterised by a separation to a very quiet internal unit and an air-handling external unit.

The internal unit provides for heating only, or for systems that provide heating and cooling, this solution is ideal for new build and modernisation projects.

Compact internal units

With their timeless design and a width of just 60 cm, these internal units can be sited close to the living space (e.g. in a utility room).

They contain hydraulic components such as a heat exchanger (condenser), DHW cylinder,heating circuit pump, instantaneous heating water heater, 3-way diverter valve, and Vitotronic 200 control unit.

Heat pump control unit with user prompts the Vitotronic 200 is structured logically,and its displays are easy to follow. The large backlit display offers a good contrast, making it easy to read. The graphic interface also displays heating and cooling curves. If a solar thermal system is connected to the Vitocal 242-S, the solar yield is shown as well.

Efficient and economical

The split heat pumps operate extremely economically in partial load operation. Inverter technology accurately matches the compressor output to the current heat demand through modulating operation.This results in high efficiency at any operating point.

Take advantage of these benefits:

  • Attractively priced split air source heat pump with heating outputs between 3.0 and 10.6 kW (air 2 °C/water 35 °C at the nominal operating point)
  • Inverter compressor for optimum output matching to the heating and cooling demand
  • Low operating costs through high coefficients of performance: COP value (COP = coefficient of performance) to EN 14511 up to 4.6 (air 7 °C/water 35 °C)and 3.5 (air 2 °C/water 35 °C)
  • Maximum flow temperature up to 55 °C at -15 °C outside temperature (with reduced output)
  • High DHW convenience through integral DHW cylinder with 220 l capacity forthe Vitocal 242-S (for Vitocal 222-S with 170 l capacity)
  • Solar connection for DHW heating with the Vitocal 242-S
  • Convenient through reversible version that enables heating and cooling
  • High efficiency in partial load operation through output-controlled compressor
  • Low sound power level of the external unit in partial load operation through variable speed fan and compressor
  • Refrigerant pipework requires no frost protection
  • Vitotronic 200 control unit that is easy to operate with plain text and graphic display


PV Solar Electricity

  • Use in conjunction with your PV solar array for greater savings and lower C02 emmissions


Great heating solutions for use with Heatpump system


Hybrid System

  • Can be utilised as a dual system with either diesel, gas or pellet boilers. The ratio is 80% of the work is undertaken by the heatpump while the remaining is with the high temperature boiler.
