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.

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.
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.
