Exotherm Water / Water

If ground water is available - especially in the area of rivers - this energy
can be used in the same way as Energia del suolo.

In this case two conveyer-wells are needed in order to get the water
up to the heatpump and afterwards back down to the groundwater again.

This water-based system is equal to the soil-based system with the
possibility to heat and cool all year long, day and night. A a way with
energy concept you posess you own energy plant - almost independantly.
