More and more owners of home pools — be they new or existing — are converting the heating systems from gas to geothermal, which is creating new opportunities for plumbing contractors. While going the geothermal route may appear more expensive initially, over time operating costs are less expensive because they are more efficient, and bring advantages when selling a home.“Geothermal systems extract heat energy from the relatively constant temperature of the earth (50-55 degrees F) rather than the outside air, which can dip to well below freezing in the winter,” says Joe Parsons, chief operating officer of EarthLinked Technologies Inc.
