Geothermal Energy

Geothermal energy is the heat from the Earth. It’s clean and sustainable. Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth’s surface, and down even deeper to the extremely high temperatures of molten rock called magma.

Almost everywhere, the shallow ground or upper 10 feet of the Earth’s surface maintains a nearly constant temperature between 50° and 60°F (10° and 16°C). Geothermal heat pumps can tap into this resource to heat and cool buildings. A geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building. In the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system. In the summer, the process is reversed, and the heat pump moves heat from the indoor air into the heat exchanger. The heat removed from the indoor air during the summer can also be used to provide a free source of hot water.

In the United States, most geothermal reservoirs of hot water are located in the western states, Alaska, and Hawaii. Wells can be drilled into underground reservoirs for the generation of electricity. Some geothermal power plants use the steam from a reservoir to power a turbine/generator, while others use the hot water to boil a working fluid that vaporizes and then turns a turbine. Hot water near the surface of Earth can be used directly for heat. Direct-use applications include heating buildings, growing plants in greenhouses, drying crops, heating water at fish farms, and several industrial processes such as pasteurizing milk.

Hot dry rock resources occur at depths of 3 to 5 miles everywhere beneath the Earth’s surface and at lesser depths in certain areas. Access to these resources involves injecting cold water down one well, circulating it through hot fractured rock, and drawing off the heated water from another well. Currently, there are no commercial applications of this technology. Existing technology also does not yet allow recovery of heat directly from magma, the very deep and most powerful resource of geothermal energy.

Best Choice Home Inspections Now Using Infrared Technology

Flir E5 Infrared Camera

Best Choice Home Inspections is now using infrared technology. Infrared or thermal imaging cameras (colloquially known as a TIC) render infrared radiation as visible light.

E5 Flir Camera
E5 Flir Camera
Best Choice Home Inspections puts this technology to use for you with dramatic MSX thermal images that clearly reveal problems from sources of energy loss, moisture intrusion and structural issues to overheating electrical components.

Hidden defects are costly to residential and commercial building owners. The FLIR infrared camera can help us quickly see and find the sources of energy efficiencies, destructive water damage, and structural issues so our customers can make informed decisions on needed repairs that can help them save money.

The FLIR infrared cameras are the IR inspection cameras preferred most by building experts for fast, reliable diagnosing of a full range of building applications.
