Eclipse Energy represents Earthlinked technology. Earthlinked the largest supplier of DX equipment in North America.

Eclipse Energy provides customized DX Geothermal systems. DX Geothermal stands for Direct Exchange Geothermal and refers to the exchange of heat from the Earth to the refrigerant filled copper lines below the ground. The sun warms up the Earth's surface to a constant temperature range. The DX system uses the Earth's stored energy, taking advantage of the constant 45°F to 65°F temperature 10 to 300 ft below the surface.

Once the refrigerant is at the Earth's temperature it enters the home where a compressor concentrates and delivers heating and cooling to the home's air and hot water. This system burns no fuel and consumes no energy beyond minimal electricity required to operate the compressor and the fan for circulating air. The need for a noisy exterior condenser is eliminated.

Eclipse Energy can quickly evaluate your home and identify the savings and benefits you and your family will enjoy from a DX Geothermal System.

Geothermal heating is the direct use of geothermal energy for heating applications. Humans have taken advantage of geothermal heat this way since the Paleolithic era. Approximately seventy countries made direct use of a total of 270 PJ of geothermal heating in 2004. As of 2007, 28 GW of geothermal heating capacity is installed around the world, satisfying 0.07% of global primary energy consumption. Thermal efficiency is high since no energy conversion is needed, but capacity factors tend to be low (around 20%) since the heat is mostly needed in the winter.

Geothermal energy originates from the heat retained within the Earth since the original formation of the planet, from radioactive decay of minerals, and from solar energy absorbed at the surface. Most high temperature geothermal heat is harvested in regions close to tectonic plate boundaries where volcanic activity rises close to the surface of the Earth. In these areas, ground and groundwater can be found with temperatures higher than the target temperature of the application. However, even cold ground contains heat, below 10' or 3 Meters, the ground is consistently 12.8°C (55°F), and it may be extracted with a geothermal heat pump. Due to recent advances in heat pump performance, this is now a rapidly growing market in the US.

Geothermal heating relies on an energy exchange between the air within the building being heated and the ground. Below ten feet the earth's temperature is fairly constant, generally around ~10ºC (~50ºF). During the summer when the ambient temperature of the building exceeds that of the ground heat pumps are used to pump heat from the building in to the transfer medium (typically water with small amounts of ethanol or glycol) and is subsequently pumped through narrow pipes into the ground so that the heat can be dissipated in the earth. When the ambient temperature falls below the ground temperature the process works in reverse. Heat pumps extract heat from the ground and use it to heat the building.

Geothermal cooling is a process by which shallow ground is utilized within a system to regulate temperature. The upper 10 feet of the earth's surface holds a stable temperature between 50° to 61°F (10° to 16°C). This stable temperature is harnessed, using a geothermal device, to draw heat energy out of a system and thus transfer the cool temperatures into a warmer area.

Geothermal Cooling:
Surface temperature has almost no effect on the ground underneath the frost line. Using this knowledge, a pump can be placed under the ground, in an area such as a basement, that effectively pulls the cool sustaining temperature from the ground. This device is connected to a loop of copper tubing or high-density polyethylene, which is literally buried underneath the earth's surface. This loop contains a refrigerant that is pumped through the tubing, exchanging the warm energy in the building with cooler energy in the ground and acting almost like a heat sink. This process is known as direct exchange and is very effective at keeping a location at a stable cool temperature.
