​​The Science Behind Geothermal

        Year-round in this area, the ground stays at about 50 degrees Fahrenheit. Geothermal systems warm or cool water (depending on the air temperature) in underground loops. The heat from this warmed or cooled water is transferred to the heat pump where it is compressed or decompressed to concentrate the effect. This hot air heat or air conditioning is then sent throughout your home. This technology is available ANYWHERE even in areas where bedrock is close to the surface.

Residential Systems
A geothermal heat pump or ground source heat pump (GSHP) is a central heating and/or cooling system that transfers heat to or from the ground. It uses the earth as a heat source (in the winter) or a heat sink (in the summer).  

         The ground source heat pump (GSHP) system can be installed in a residential structure of any size, anywhere, whether it is single-family or multi-family. GSHPs can be installed on almost any size lot: under lawns, landscaped areas, driveways, or the house itself. An existing house can be retrofitted with a GSHP using the duct work that is already there. 
          The Department of Energy (DOE) and the Environmental Protection Agency (EPA) have both endorsed ground source heat pump systems as among the most energy efficient and environmentally friendly heating, cooling, and water heating systems available. In a 1993 report, the EPA concluded that geothermal technologies represent a major opportunity for reducing national energy use and pollution, while delivering comfort, reliability and savings to homeowners.

Commercial Systems
Ground source heat pumps (GSHP)s are a cost effective, energy efficient, and environmentally friendly way of heating and cooling buildings. Both the DOE and the EPA have endorsed the technology. GSHPs reliably deliver quality air-conditioning and heating, on demand, in every season. GSHPs are appropriate for new construction as well as retrofits of older buildings.  [Nobel Research Center] Their flexible design requirements make them a good choice for schools, high-rises, government buildings, apartments, and restaurants--almost any commercial property. Lower operating and maintenance costs, durability, and energy conservation make Ground Source Heat Pumps the smart choice for commercial applications.

Ground Source Heat Pumps offer great benefits:

  • Simultaneously heat & cool different parts of the same building
  • Very quiet--users do not know when the system is operating
  • Can be set up in multiple zones, with each zone having an individual room control
  • Greater freedoms in building design due to 50-80% less mechanical room space
  • Pipes have 50-year life expectancy
  • ​Ground heat exchanger is maintenance free and will last 40+ years

GSHPs offer great savings:

  • Very competitive on initial costs and lower lifecycle costs than most HVAC systems.
  • Savings of 25-50% on energy consumption
  • Lower peak demand, lowering your operating costs
  • Water heated with waste heat from air conditioning at no cost in the summer and at substantial savings in the winter
  • Some utilities offer rebates or incentives to their customers who purchase GSHPs. 

GSHPs are environmentally friendly:

  • Conserve natural resources by providing efficient climate control and thus lowering emissions
  • Minimize ozone layer destruction by using sealed refrigeration systems, which seldom or never have to be recharged
  • Use underground loops to transfer heat, with no external venting and no air pollution
  • Very energy efficient, with the earth providing over 70% of the energy required to heat and cool
