Vitocaldens 222-F with outdoor unit

Combines highly efficient condensing technology with the use of free environmental energy:  Vitocaldens 222-F

The  Vitocaldens 222-F compact hybrid appliance makes it possible to find the optimum combination of renewable and conventional energy sources. Constantly fluctuating energy prices mean it is difficult for consumers to make the right decision in favour of both economically and environmentally responsible heating systems that will remain viable in future. The compact hybrid appliance provides a solution with low running costs and low CO₂ emissions for modernising heating systems. This gives the user the greatest possible assurance that the more favourable energy source will be used in each case.

Special features of the  Vitocaldens 222-F

Modernisation with a secure future

Powerful for comfortable and convenient heating and DHW, with compact dimensions and quiet operation. And above all, thanks to the two independent heat generators in the appliance – condensing boiler and heat pump – it is flexible enough for an optimum, futureproof response to developments in energy markets. Efficiency is assured at all times – for example, the Vitocaldens 222-F has an A++ energy efficiency label.

Hybrid Pro Control: The right energy mix for efficient operation

Thanks to Hybrid Pro Control, the control unit recognises, for example, for how long the heat pump will be able to cover the entire heat demand on its own. If this time is exceeded, it will then call for backup from the condensing module.  Hybrid Pro Control automatically determines the timing and responds accordingly: it uses the currently set energy prices for electricity and gas to calculate which energy source can be used most efficiently at any given time. Hybrid Pro Control  maintains an overview of the entire system at all times. The integrated  energy manager automatically determines the most efficient operating mode (economy or ecology and comfort).

Meeting all your needs: DHW convenience with integral loading cylinder

The DHW loading cylinder with a capacity of 130  litres provides sufficient DHW at any time – even when demand is high. Ideally, the hot water is generated economically using the heat pump.

Compact, efficient, quiet: indoor and outdoor units

Integrated into the indoor unit are two heat generators, a DHW cylinder and all the hydraulic components – taking up an installation area of just 0.36  square metres. The weatherproof outdoor unit allows for flexible siting. Thanks to its compact dimensions, the unit can be positioned anywhere as a freestanding unit or mounted on an external wall.
