The operating modes provided by the different technologies included in the ecoGEO geothermal heat pumps
are outlined below.
HEATING MODE
During the normal operating cycle, heat pumps draw energy from the ground for producing hot water in
the heating system. Its operation can be split into four sub-processes which are repeated on a cyclical
basis.
The antifreeze mixture is successively circulated by a circulation pump through an ground source
system, where it absorbs heat from the ground, and the evaporator, where it transfers heat to the fluid in
