A geothermal heat pump mostly comes attached with a heat exchanger, pipes, and ductwork. The ground will be usually warmer when compared to the air  temperature in winter, and the role of the heat exchanger is to transfer this warmth into your building. Further, its function will be reversed when the ground will be relatively cooler in summer. The outcome is that it not only helps for energy and cost savings but also helps for effective removal of excess heat from  your building.

In contrast to conventional HVAC pumps, geothermal heat pumps consume very less energy. Further, the geothermal pumps result in decreased emissions,  which at the same time is higher in air source heat pumps. Further, an air source heat pump can reach only up to 250% efficiency on a cool day while a GHP can reach up to 600%.

As in the case of other types of heat pumps, geothermal heat pumps can be used to heat and cool water. There are also certain models of geothermal systems  that come with variable fans and multi-speed compressors in order to help for increased energy savings. Above all, a great thing regarding geothermal heat pumps is that they require less maintenance and hence last for longer period.

The installation cost of a geothermal heat pump is relatively high. However, you can be contented that it will fetch you huge benefits by way of additional  energy savings within five to ten years.

• They can be selected for standard boiler/tower or geothermal applications
• Multiple configurations reduce design time and help you avoid obstructions and use minimum ductwork to reduce installation costs
• Multiple factory-installed features and options allow you to select the unit that closely matches your application requirements while lowering installation costs.
• Small footprint design makes it easier to meet space requirements for new construction and replacement applications

Factory-installed Features and Options

• R-410A Refrigerant – Has no ozone depletion potential or phase-out date, helping to minimize environmental impact and protect against refrigerant availability issues over the economic life of your equipment investment.
• MicroTech® III Unit Controller – Open Choices^TM control feature allows Standalone or easy integration into a LONWORKS® Communication network (LonMark 3.4 Certified) using and add-on communication module.  BACnet® communication module available in early 2009.
• ECM fan motor – improves unit efficiency and maintains constant airflow over varying system static pressure.
• Auxiliary/Emergency Electric Heat Coil (5kw or 10kw – single point power) – in emergency situations where the compressor no longer functions, the integral electric heat coil can provide temporary heating until the compressor is replaced.
• Desuperheater – this heat exchanger system aids in domestic hot water production while the water source heat pump is in the cooling mode of operation.
• 2-way motorized valves (NO or NC) – ideal for variable pumping applications – when there isn’t a call for unit operation, the valve closes, reducing the flow requirements through the condenser water loop.
• Compressor Sound Blanket – new and improved compressor sound blanket for sound sensitive applications.
• Painted Cabinet – suitable for residential applications.

Because underground temperatures do not change and remain relatively constant year-round, a geothermal system, which consists of an indoor unit and a buried earth loop, capitalizes on these constant temperatures.

The winter, fluid circulating through the system’s earth loop absorbs stored heat and carries it indoors. The indoor unit compresses the heat to a higher temperature and distributes it throughout the building. In the summer, the system reverses, pulling heat from the building, carrying through the earth loop and depositing it in the cooler earth.

Why are geothermal heat pumps more efficient than air source heat heat pumps?

The geothermal system cycles water from a well, pond, lake or river, or water piped through underground plastic tubing, to warm or cool the heat pump’s refrigerant. Liquid such as water or an antifreeze solution is a much better heat transfer medium than air. Overall, the liquid medium for heat transfer is about 30% more efficient than air.
