Americans usually rely on two familiar systems to heat homes or buildings:
- fuel-powered furnaces or boilers (which burn gas, oil, or propane) and electric-powered air-source heat pumps or baseboard radiant heat. However, these traditional systems present two drawbacks.
- First, even highly efficient models pollute the environment because fuel must be burned to produce heat.
- Second, energy prices are rising.
Accordingly, people want cost-effective long-term heating and cooling options.
- Geothermal systems are one such option, they are being installed in homes, businesses, and schools across the country.
