round Source Heat Pumps are a
modern technology for heating and
cooling of buildings. They make use
of geothermal energy (the heat stored beneath
the earth surface) almost anywhere throughout
Europe.Ground Source Heat Pumps allow both
to save primary energy as well as to save heating and cooling cost.

Ground Source Heat Pumps have seen a
tremendous market development in some European countries over the last years. Sweden and
Switzerland are leading since the beginning in
the 1980s, however, some other countries with
a slow start in the same time, like Germany,
now show good growth rates. In France, the
development started later, but the opportunitiesfor a widespread, successful use of GSHP are
very good.

Ground Source Heat Pumps systems consist
of three main components: the ground side, the
heat pump itself, and the building side. A good
design must take care of the whole system,
matching the components in such a way that
the most effective operation and the highest
comfort can be achieved. Thisbrochure is
intended to show the advantages of Ground
Source Heat Pumps and other uses of shallow
geothermal energy.

Sweden (>250’000) and Germany (ca 150’000)
today show the highest absolute numbers of
GSHP; the highest market share (GSHP per
capita) has been achieved in Sweden, while
the highest areal density of GSHP can be found
in Switzerland.

Geothermal Heat Pump (GSHP)
Technology

G

eothermal heat pumps (also called
Ground Source Heat Pump, GSHP) are
systems with 3 main components:

• the ground side to get heat out of or into the
ground
• the heat pump to convert that heat to a suitable
temperature level
• and the equipment inside the building transferring the heat or cold into the rooms...
