How Geothermal Works

Geothermal heating and cooling systems are the most efficient and environmentally friendly systems on the market today. These systems work differently than conventional systems by taking advantage of the sun’s renewable thermal energy that is absorbed and stored by the earth. At a depth of 20 feet the ground maintains a fairly constant temperature of ranging from 45 to 77 degrees F depending on your region of the United States.

Pipes in the ground circulate a water solution and carry renewable thermal energy to the heat pump in the winter for heating and remove heat from the building into the ground in the summer. Forced air or low temperature hydronic systems distribute geothermal heating and air conditioning. Most systems use electric heat pumps capable of increasing the ground’s thermal energy in the winter and concentrating and depositing the a building’s thermal energy into the relatively cool ground in the summer when air conditioning.

Aztech Presents on Networked Geothermal Systems for Capital District Engineers' Week

John Ciovacco, President of Aztech Geothermal will be giving a virtual presentation the rapidly emerging topic of Networked Geothermal Heat Pump Systems. The seminar will cover the passage of the Inflation Reduction Act (IRA), expanding and extending federal tax incentives, the Utility Thermal Energy & Jobs Act (UTENJA) requiring all major utilities to file their plans for networked geothermal pilot projects and NYSERDA’s Community Heat Pump Systems program.
