A Direct Exchange DX geothermal system is more efficient than
an air heat pump because the temperature of the earth is always
constant. Air heat pumps lose heating efficiency as the outdoor
air temperature falls. However, a geothermal pump that services a
building, whether that building is located in Australia, Alaska or in
Quebec, will always have the same guaranteed efficiency because it
doesn’t depend on atmospheric conditions, but on terrestrial conditions
that remain uniform and stable at all times.
When comparing a DX system to a traditional geothermal heat
pump (that uses antifreeze as a secondary fluid in the geothermal
exchanger), you would find a 5 to 6% energy loss due to thermal
transfer. A larger geothermal field is also required than for the DX
system. As a result, the initial
The Direct Exchange DX system is also certified
by the CANADIAN GEOEXCHANGE COALITION, in
accordance with CSA 448 installation standards.
Please contact one of our technical consultants for more information on our various technologies and don’t hesitate to come visit our functional installations in our SHOWROOM. We have functional Direct Expansion technologies for heating and air conditioning and antifreeze geothermal installations on our premises in order for you to familiarize yourself with a geothermal system network.
