Schools:
Edison School
Located: Edison, CO
Square Feet: 20,000
Loop Type: Vertical Bore Holes

The Edison School, built 1929, still used a coal fire boiler for heat and window mounted air conditioning units for cooling. After performing soil conductivity tests and performing a test well, it was determined that a vertical well system will provide the best overall heating and cooling performance at the least cost for Edison School.  Twenty vertical wells were drilled to a depth of 300 ft. Twenty-five heat pumps were installed throughout the Edison School to give individual heating and cooling comfort control to all affected rooms.  This new system extracts heat from the earth loop during winter months and rejects heat to the earth loop system during cooling periods.   The best thing... no coal dust... and individual comfort control.
