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

This is made possible by a new and innovative EPP housing design along with the latest radial 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 lower housing section ensures very low sound emissions. By reversing the process, the “ac” variant can modulate to provide cooling output.
The x-change dynamic is equipped with the x-center x40 control.
