Exotherm Soil / Water

The natural temperature of the ground at about 100m depth is
approximately between 8° - 12°C. Geothermal probes collect
this temperature and feed the heat pump which uses this
energy and turns it into heat of 70°C. This heat is then transfered
to the inhouse water system.

During the summer this system may be simply switched to
the cooling function and provides a temperature difference
towards the outside temperature by 8°C.
