2. High Efficiency and Stable Capacity
When geothermal heat pumps are properly designed, the liquid temperatures in the loops ensure that the equipment will operate with much higher efficiency and economy than conventional air source and fossil fuel equipment. Cool water is fed to the equipment condenser rather than warm air, which allows compressors to operate against low refrigerant pressure differences with much lower power requirements. In the heating mode, liquids, which are much warmer than the outdoor air, deliver heat to the refrigerant in the evaporator coil. This allows much higher capacity and air temperature. The loop temperatures vary little with outdoor temperature, so capacity is stable. Geothermal heat pumps also require very little fan and pump energy when compared to central and variable air volume systems that are widely used in larger buildings.3. Comfort and Air Quality
Geothermal heat pumps can achieve high efficiencies without compromising latent cooling capacity. Since outdoor air temperatures dictate the lower limit of discharge pressure, some manufacturers increase suction pressure to raise efficiency. This results in poor dehumidification, which compounds comfort and indoor air quality problems. These problems are often on the rise in public and office buildings with high outdoor air requirements. Geothermal heat pumps can often effectively deal with humidity problems without the dedicated humidification or latent heat recovery equipment that is now being specified in many applications. Geothermal heat pumps can also deliver warm, comfortable air in the heating mode.4. Simple controls and Equipment
Complex controls are not needed to maintain comfort and part load efficiency. It is highly recommended that expensive and proprietary devices not be used in order to lower geothermal heat pump system cost. Each zone can have a dedicated heat pump that can be locally controlled for optimum comfort. Air flow is constant volume, and the only central control is optional variable speed drive on the water pump.5. Low Maintenance Cost
Geothermal heat pumps can be installed with no outdoor equipment; thus, corrosion and weathering are not normal problems. All the heat pump equipment is indoors. The equipment is never exposed to the high or low refrigerant pressures experienced by conventional equipment. High maintenance cooling towers can be avoided on most systems.6. No Need for Auxiliary Heating
The capacity of geothermal heat pumps almost always exceeds the zone heating requirement in commercial and institutional buildings. The heating mode is easily activated by de-energizing the reverse valve (with the thermostat). Heating efficiency and economy are unmatched by conventional equipment.7. Low Cost Water Heating
Most commercial buildings (even in cold climates) have an abundance of waste heat from internal loads that is absorbed by the cooling system. Geothermal heat pumps can easily “pump” this waste heat to meet the water heating requirements. This can be done with heat recovery coils on selected heat pumps or with dedicated water-to-water heat pumps. In addition to being a very low cost heating method, heat recovery can reduce the required the size of the ground heat exchanger since much of the heat is removed before entering the ground loop water in the critical cooling mode.8. No Outdoor Equipment
Most geothermal heat pumps do not require unsightly outdoor equipment. This frees space for other users and eliminates safety problems and potential damage that may occur with conventional outdoor equipment. Schools are applications where this is extremely valuable since special precautions are often required to restrict access of children to outdoor equipment. Hotels can put to use the roof space usually allocated for cooling towers for other purposes like Food & Beverage, swimming pools and/or solar power panels. Residential developments can use the roof tops for swimming pools, gardens and/or solar power panels.9. Packaged Refrigeration Equipment
Water-to-air and water-to-water heat pumps are self contained refrigeration systems. This reduces the chance of refrigerant leakage and equipment failure due to improper field charging and connections.Competitive Advantages: Independent Evidence
1. "Geothermal Heat Pumps (GHPs) are the most energy-efficient means of (heating and) cooling buildings in most areas of the US. Their wider use could cut energy costs, conserve fossil fuels, and reduce carbon emissions." Geothermal Energy – Outlook Limited for Some Uses but Promising for Geothermal Heat Pumps; United States General Accounting Office.
2. "The biggest advantage of GHPs is that they use 25-50% less electricity than conventional heating or cooling systems. The underground piping often carries warranties of 25-50 years, and the heat pumps often last 20 years or more." US Department of Energy – Energy Efficiency & Renewable Energy.
3. "DOE’s Office of Geothermal Technologies seeks to increase annual installations of GHP systems to about 400,000 by 2005 and reaching about 2 million installed (cumulative) that same year. Achieving the goal of 400,000 annual installations by 2005 will save consumers over $400 million per year in energy bills and reduce U.S. greenhouse gas emissions by over 1 million metric tons of carbon each year." US Department of Energy, office of Geothermal Technologies.

Geothermal India™ Features and Benefits
Feature 1 - Water-loop system
The boiler and cooling tower have been replaced with a buried earth heat exchanger. Heat is absorbed from or rejected to the ground, and the external energy needed to operate a boiler or cooling tower is eliminated. Benefits: Lower operational costs through lower energy demand compared to conventional air-conditioning solutions. Eradication of unsightly cooling towers from the top of buildings frees space for other usages.
Feature 2 – Heat Pump
Extracts heat waste from the interior air. Benefit: The heat waste can be utilized for free hot water.
Feature 3 – Control Board
Offers two levels of solid-state digital controls: the CXM and DXM control boards to notify the owner of potential unit problems before a lockout occurs. Benefits: Pro-active customer service allowing for greater performance of the central unit and more effective and efficient care.
Feature 4 - Sound standard ARI 260-2000
Benefit: The only certified units with certified sound standards, ensuring the units perform as quietly as the sales literature promises.
Feature 5 - Torsion-Flex Blowers
Benefit: Allows for easy service and reduces vibration from the blower motor during operation.
Feature 6 - E-Coated Air Coils
Benefit: Provides years of protection against coil corrosion from airborne chemicals resulting from modern building material out gassing and most airborne environmental chemicals. E-Coated air-coils enhance corrosion protection to nearly 20 times that of a traditional uncoated coil. Test based upon ASTM B117 Salt Spray test hours.
Feature 7 - Dual Level Vibration Isolation
A double isolation compressor mounting system. Benefit: Deadens vibration and provides quiet operation.
Feature 8 - DDC Controls
Factory mounted LONWorks or Multi-ProtoCol (MPC) DDC controllers. Benefit: Give owners the ability to implement a variety of building automation systems such as BACnet, ModBus, and Johnson N2. Through internet access, individual units, unit zones, and entire building systems can be monitored and controlled with the click of a mouse. The systems provide unit status, set-point control, performance curves, and fault indications.
