Is geothermal energy is efficient but costly?

With a geothermal heat pump you’ll enjoy these benefits:

Efficiency & Lower Operating Costs – Geothermal heat pump systems save money. … For every unit of electricity the system uses, it provides three to four units of heating energy – an efficiency of 300% to 400%.

How warm does geothermal heating get?

Depending on latitude, ground temperatures range from 45°F (7°C) to 75°F (21°C). Like a cave, this ground temperature is warmer than the air above it during the winter and cooler than the air in the summer.

Does geothermal increase home value?
