The Benefits of Geothermal Heat Pumps

Even in countries without large resources of geothermal, geothermal heat pumps can still provide space heating and air conditioning.

Such as a refrigerator or air conditioner, the system uses a heat pump to force the transfer of heat from the ground to the application.

A ground-source heat pump system uses the shallow ground (usually at 10-12 ° C, 50-54 ° F) as a heat source, so take advantage of seasonal temperatures. In contrast, the air-source heat pump pulls heat from the cold outside air and thus needs more energy.

Geothermal heat pumps are alike to regular heat pumps, but use the ground as an alternative of outside air to deliver air conditioning, heating, and, in many cases, hot water.

Because they use the natural heat of the earth, they are one of the most efficient heating and cooling technologies that are convenient and available today.

The heat pump system uses solar energy stored in the earth's crust. Energy is transferred to and from the earth's surface by solar radiation, wind, and precipitation.

As a consequence of this solar energy, the temperature of the earth at a depth of 10 meters remains constant and proportional to the air temperature annual average.

Between surface and a depth of 2.5 meters (maximum depth for the horizontal loop), the ground temperature will swing above and below the air temperature annual average, depending on the geographical location, soil type in the humidity level.
