The application of geothermal heating/cooling, also know as ground source heat pump, has been named "the most energy-efficient and environmentally sensitive of all space conditions systems," by the EPA. The system's basic concept takes advantage of the earth's constant temperature, approximately 55 degrees, to heat and cool your home. By tapping this steady flow of heat from the earth in the winter, and displacing heat in the earth in the summer, a geothermal system alone can save you 40 to 70% in heating costs and 30 to 50% in cooling costs compared to conventional systems.
Ground source heat pumps work by circulating water or a water/antifreeze solution through a closed loop of copper pipe that is buried in the ground. The closed loop system is laid out vertically in 50-250 foot deep holes drilled like a well. The heat pump then extracts ground heat in the winter (heating) and exhausts heat back into the ground in the summer (cooling).
While GSHP's require a small amount of electricity to concentrate the energy and circulate it through the system, most systems derive approximately 70% of its energy from a clean, renewable source-the earth.
GSHP may also be combined with Solar Panels and/or Cogeneration, which can be used to power the pumps, to create a renewable heating and cooling system which is off the grid. This innovative approach is used by CCB to bring you a completely renewable source of energy.
