Ground loops and a heat pump.
Geothermal energy heating and cooling systems.
Geothermal heating cooling ghc systems convert stored thermal energy in the earth to heating and cooling for homes and businesses.
Growth in the geothermal heating and cooling market averages 12 annually as demand continues to rise for highly efficient hvac systems leveraging sustainable energy.
Geothermal heat pumps can operate in any climate hot or cold because of the earth s constant underground temperature from 45 to 75 f depending on location.
This simple straightforward and convenient system can provide both heating and cooling which saves you money space and so many headaches.
Compared to other types of green energy systems geothermal provides steady production.
Geothermal is the only renewable that provides reliable operation 24 hours a day 7 days a week 365 days a year making it the reliable renewable by using the infinite energy source in the earth a geothermal heat pump operates efficiently and effectively all year round rain or shine day or night windy or not.
The heat pump unit the liquid heat exchange medium open or closed loop and the air delivery system ductwork and or the.
At a minimum conventional heating and cooling require two distinctly different systems for different seasons.
A geothermal cooling and heating system has three main components.
As a heating and cooling system geothermal heat pumps can cut maintenance costs as there are fewer components that can break.
Geothermal heat pumps can be used in any climate.
Geothermal energy is considered a renewable resource.
Approximately seventy countries made direct use of a total of 270 pj of geothermal heating in 2004.
In fact millions of ghp systems are already heating and cooling homes and businesses worldwide and that includes all 50 u s.
Ground source heat pumps and direct use geothermal technologies serve heating and cooling applications while deep and enhanced geothermal technologies generally take advantage of a much deeper higher temperature geothermal resource to generate electricity.
Today system pricing is more competitive than it was a decade ago because there are many more manufacturers selling ground source heating and cooling systems and there are more experienced installers competing.
Geothermal heating is the direct use of geothermal energy for some heating applications.
The systems require use of drilled wells piping loops and efficient heat pumps to transfer heat between the wells and a home or business.
For example solar powered heating and cooling systems only collect energy during peak sunlight hours.
As of 2007 28 gw of geothermal heating capacity is installed around the world satisfying 0 07 of global primary energy.
System life is estimated at up to 24 years for the inside components and 50 years for the ground loop.
Even though the installation price of a geothermal system can be several times that of an air source system of the same heating and cooling capacity the additional costs are returned to you in energy savings in 5 to 10 years.
