Air-to-water heat pump with higher flow temperature. 22 kW heat output.

Efficiency is a key focus.

This high-efficiency air-to-water heat pump with 22 kW heat output heats living areas up to 500 sqm and is ideal for existing or new-build apartment blocks. Flexible expansion options and compact design are included.

  • Extremely high performance. Designed for areas up to 500 sqm.
  • Flow-optimized casing. Low frequencies that can be unpleasant are effectively reduced.
  • Excellent efficiency values. Demand-based regulation via two compressors in the refrigeration circuit – if only one is required, the other switches off.
  • Always comfortable. Quick domestic hot water preparation via a flow temperature up to 65 °C – depending on the day consumption.
