Geothermal Energy Heating And Cooling Systems

Ground loops and a heat pump.

Geothermal energy heating and cooling systems.

A geothermal cooling and heating system has three main components. As of 2007 28 gw of geothermal heating capacity is installed around the world satisfying 0 07 of global primary energy. This simple straightforward and convenient system can provide both heating and cooling which saves you money space and so many headaches. 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.

Growth in the geothermal heating and cooling market averages 12 annually as demand continues to rise for highly efficient hvac systems leveraging sustainable energy. Humans have taken advantage of geothermal heat this way since the paleolithic era. Geothermal heating cooling ghc systems convert stored thermal energy in the earth to heating and cooling for homes and businesses. For example solar powered heating and cooling systems only collect energy during peak sunlight hours.

The heat pump unit the liquid heat exchange medium open or closed loop and the air delivery system ductwork and or the. As a heating and cooling system geothermal heat pumps can cut maintenance costs as there are fewer components that can break. At a minimum conventional heating and cooling require two distinctly different systems for different seasons. In fact millions of ghp systems are already heating and cooling homes and businesses worldwide and that includes all 50 u s.

Geothermal energy is considered a renewable resource. The systems require use of drilled wells piping loops and efficient heat pumps to transfer heat between the wells and a home or business. 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. Geothermal heat pumps can be used in any climate.

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. System life is estimated at up to 24 years for the inside components and 50 years for the ground loop. Geothermal heating is the direct use of geothermal energy for some heating applications. Approximately seventy countries made direct use of a total of 270 pj of geothermal heating in 2004.

Deep and enhanced geothermal systems. Compared to other types of green energy systems geothermal provides steady production.
