Geo-Geothermal Systems
EarthLinked® Naturally Clean and Efficient
 The EarthLinked® System works with nature to deliver the highest efficiency using the sun's energy stored in the earth. Rather than consuming fuel to produce heat, EarthLinked® transfers heat energy from the earth into your home in the winter, and the system removes heat and humidity in the summer. Because it takes less energy to tranfer heat than to create it, EarthLinked® delivers up to four times more energy than it uses.

EarthLinked® offers the most energy efficient means of heating and cooling building in most areas. Transferring renewable enrgy reduces cooling costs an average of 30% as compared to a 10 SEER air conditioner, and heating costs by 75% as compared to electric heat. EarthLinked® water preheating is four times as efficient as electric resistance water heating.
It can reduce annual energy consumption over 40% compared to air source heat pumps, and as much as 70% measured against standard air conditioner with electric resistance heating, and 20% compared to conventional geothermal units.
Advantages to Home and Building Owners EarthLinked® yields many advantages over air source heat pumps, closed-loop GeoExchange systems and other direct GeoExchange systems.
Advantages Over "High-Efficiency" Air Source Heat Pumps
- Highest average COP (heating) and EER (coding) efficiency ratings.
- Saves from 40 to 60% in operating costs on an annual basis.
- Increases comfort by efficiently using the favorable earth heat source to provide 100°F supply air.
- Does not lose efficiency as ambient air temperature drops.
- Can be located in a utility room or basement because of no need to circulate air over an exterior coil.
- Quiet operation resulting from total system enclosure and elimination of exterior fan and motor.
- Exterior condenser/evaporator unit is buried out of sight, protected from damage, theft and weather.
- Approximately one-half the size and weight of a typical air source heat pump unit.
- Not subject to freezing; no defrost cycle required; no supplemental heat required.
- Eliminates the exterior coil, fan, fan motor and capacitor, defrost timer, and ancillary wiring, making it mechanically and electrically simpler.
- Has greatly improved reliability and service life because of its simplicity and stable temperature source.
- Achieves high efficiency without having to utilize variable speed compressors or multi-speed fans.
- Extends compressor life by reducing compressor wear caused by temperature fluctuations in ambient air and by preventing liquid refrigerant from reaching the compressor.
- Energy demand charge reduction, where applicable.
Advantages Over Water Source Closed-Loop Geo Systems
- More efficient operation of the compressor, evaporator, and condenser with ECR Refrigerant Flow Controls.
- Eliminates intermediate closed-loop plastic piping system (which must be purchased in parts, assembled on-site, installed, filled with antifreeze and water, and pumped constantly while system is operating.)
- Continues to operate even when evaporator surface (earth loop) is enveloped in ice.
- Mechanically simpler and more reliable; easier to service.
- Utilizes bore holes 3" in diameter in contrast to 6" bore holes.
- Lower installation costs can result from smaller, shorter bore holes; less loop per ton; and less grout.
- Unique optional capability of water pre-heating "on demand" during any season, or as a "desuperheater".
EarthLinked®Advantages Over Other Direct GeoExchange Systems
- Provides more efficient operation of the compressor, evaporator and condenser with ECR refrigerant flow controls.
- Allows for more earth loop installation options, including shorter vertical, diagonal and horizontal loops, which are applicable to more new construction and retrofitting opportunities.
- System capacity and performance ratings are given for specific geographic area.
- Has the unique option of water heating full-time, water pre-heating during any season, or by utilizing a desuperheater.
 Advantages to Dealers and Installers Dealers who have installed a traditional closed-loop GeoExchange System know how difficult and expensive installing the large plastic intermediate earth loop and the related flow center can be. ECR loops are easier to install because they use a much smaller bore hole and less excavation than water-based systems. Therefore, smaller and more maneuverable drilling equipment can be used.
Factory Assembly Makes Installation Simpler Because EarthLinked® needs no intermediate loop, the installer needs no plastic loop fusing tools, pumps to add antifreeze or training to assemble the loop. ECR loops are factory assembled. The unit weighs one-third that of a closed-loop system or high efficiency air source heat pump.
A Long List of Benefits for the Dealer ECR and the EarthLinked® GeoExchange System provide its vendors with qualified sales leads, training and support, ease of installation, reliability, as well as a wide range of other benefits:
- higher profit than other heat pumps because it is a proprietary, value-added product
- greater operating cost savings accelerate cost recovery
- easier, quicker installation than water source Geo systems
- lower installed cost potential gives opportunity for quicker cost recovery than water source Geo systems
- no purging or plastic fusing and no special tools or equipment needed
- 85% smaller vertical bore and trenching requirement than water source Geo systems
- size and weight of unit is less than one-half of water source Geo units
- greater reliability and fewer call-backs result from mechanical simplicity and ECR Refrigerant Controls
- Refrigerant Controls assure easier refrigerant charging and service by viewing sight glass without need for thermometer or charging charts; and checking refrigerant charge during servicing does not require gauges (gauges are used only on first A/C operation)
- more options with vertical, horizontal or diagonal earth loops (for lowest cost alternative to meet site conditions); water heating options; and location of unit in basement, utility room or outside
- earth loops are pre-assembled and can be shipped to site in 34" coil on pallet with unit
- quieter operation and greater comfort from constant earth temperature source and no defrost cycle
- 75% reliance on renewable energy results in conservation of natural resources and clean air and water
- environmental friendliness creates pride in consumers and dealer
- cleaner indoor air results from greater filtration during longer run cycles, and no combustion
- happy customers provide word-of-mouth advertising
