Christ Church Bronxville has installed a geothermal heating system that uses a network of underground pipes extending into a nearby parking lot. The system involves boreholes drilled hundreds of feet into the ground, where water is circulated to absorb heat from the earth below.
The project represents an experiment in urban geothermal technology that could reduce building heating emissions, though specific carbon reduction figures were not provided in available reporting. Geothermal systems typically eliminate the need for fossil fuel combustion for heating, potentially cutting building emissions significantly.
