Brine / water heat pumps x-change® dynamic terra BW I
The modulating x-change dynamic terra brine/water heat pump extracts thermal energy from the earth by means of a geothermal collector or geothermal probe containing a circulating heat transfer fluid (the brine) and converts it into heat for heating.

The x-change dynamic terra is characterised by its extremely efficient operation, whereby the scroll compressor, heat source pump, and charge pump are speed-controlled. This enables it to adjust its output automatically to the building’s heat demand. The highly efficient integrated brine pump with expansion tank and flow sensor – as well as the optional passive cooling station (on the pc version) – ensure a high degree of integration and help to reduce the installation time considerably. 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.
