Water-to-water heat pump x-change® dynamic water WW I
The modulating x-change dynamic water (water/water) heat pump extracts thermal energy from the groundwater using an extraction and absorption well.

The thermal energy is transferred to the heat pump via an intermediate heat exchanger (groundwater station). This is then converted by the heat pump so that it can be used for heating. State-of-the-art heat pump technology ensures highly efficient operation. The scroll compressor, heat source pump, and external charge pump are speed-controlled. This allows the heat pump to adapt to the current level of heat demand. The compressor features vibration decoupling and so produces very low sound emissions. Together with the additional sound-proofing mats on the continuous housing cover, this ensures virtually silent operation.
