Geothermal energy is, quite literally, heat from the earth.
Deep within the Earth thermal energy is created at the core through immense pressures and radioactive decay; temperatures are estimated to reach 5,000oC (approximately 9,000oF)! This heat energy is conducted outward from the core and surrounding mantle and eventually into the rock and water in the Earth’s crust. This is why, even on the coldest winter day, groundwater temperatures in the mid-Atlantic area remain around 13oC (55oF)!
HTG employs standing column well technology to capture the earth heat most efficiently using proprietary pumping and control systems – this saves 50 to 75% over typical geothermal drilling costs. Our systems circulate the water through high-efficiency heat exchangers to extract the heat energy and transfer it to air or water in pools or buildings. The heat exchangers can be reversed in cooling mode, transferring heat back into the ground to be stored and captured later. This energy source is completely renewable, green, and very clean.
