He explained the whole geo-thermal system to us. In involves exchanging heat with the earth. Water, at a constant 55 - 58 degrees, is taken from an aquifer that conveniently runs underneath the school. It then runs through the HVAC structure and is returned to the ground. It will provide balanced heating, with no combustion or pollutants.
Air quality improves and with greater efficiency.
One room at a time may be heated or cooled if desired. No other school in Illinois has done this yet. Several thousand dollars will be saved in maintenance. Also, no other dollars will be used from anywhere else in the district. The start of the 2000 - 2001 school year will be delayed to ensure enough time for the conversion.
