Investing in a geothermal system can cut residential energy costs by 30 percent over natural gas systems, and up to 50 percent over electric resistance heating. Over the life of the system, you could expect to save $20,000 on your utility bills.

The key benefit of a geothermal heating and cooling system is its energy efficiency - for every one unit of energy it uses, it produces 2.5 to 3.5 units of heat. That's an average efficiency of 300 percent!
For comparison, a high-efficiency natural gas furnace would have an efficiency of 92 percent, meaning 92 cents out of every energy dollar used is put back into your home in the form of warmed air. If you have an older home, you might be replacing a furnace or boiler with an efficiency of 60 percent or even less.
That means with a geothermal system, you'll get the most value, comfort and convenience for your energy dollar.
