x-change® dynamic pro AW E

More efficient and sustainable. The modulating x-change dynamic pro AW E air/water heat pump is bound to impress thanks to its extremely efficient and virtually silent operation.

x-change dynamic pro AW E air/water heat pump for outdoor installation

This is made possible by the latest axial fan technology, which includes a whisper mode and a large modulation range for the compressor, fan, and charge pump. Together with the cooling circuit featuring multiple insulation and triple sound proofing, the high-quality housing with robust stainless steel cover ensures the lowest possible sound emissions. By reversing the process, the heat pump can modulate to provide cooling output. Operation is highly sustainable thanks to a new environmentally compatible coolant. For even greater sustainability, it can be combined with a solar panel system and electrical energy storage unit. Hybrid operation with other renewable energies, such as solar thermal energy or biomass, is also possible. The x-change dynamic pro air/water heat pump scores well with its outstanding efficiency, extremely low sound emissions, and state-of-the-art control technology. Installation effort is reduced to a minimum and a new small size has been introduced for energy-efficient new builds, perfectly rounding off the range of possible applications by catering for lower outputs.

The x-change heat pump


Sound level and sound insulation

With their exceptionally effective sound attenuation and vibration damping, our heat pumps are hardly any louder than a ticking alarm clock.

Own consumption

Reduce your electricity costs by combining a solar system and electrical energy storage unit with an x-change heat pump.

Heat pump & cooling

Provided that the necessary technical requirements are met, heat pumps can also be used to cool living spaces, regardless of whether they take the form of an air-to-water, brine-to-water, or water-to-water heat pump.

Heat pump with solar panels

It makes perfect sense to combine a heat pump with a solar panel system: Heat pumps need conventional electricity to operate – a solar panel system generates electricity from solar energy. And our x-change dynamic heat pumps have an integrated solar panel interface as standard.

Which heat pump should you choose?

Heat pumps can be used in large or small properties, detached houses, and blocks of flats – but deciding which one is right for your own construction or modernisation project primarily depends on the conditions in and around the building. There are a few basic details and criteria that can help you with the selection process.
