How geothermal works

[luv2flip]

For the ones who replied to my post Friday I got this information for you.

You already have a heat pump in your home , your refrigerator. If you put your hand behind it, you'll feel the heat that has been pumped from the inside and from its contents. It's the same principle that the geothermal heat pump uses to move heat to and from the home and earth.

In the summer, the heat pump extracts heat from the conditioned space and sends it out to the earth loop to warm the relatively cool ground.

In the winter, this process is reversed. The heat pump extracts heat from the relatively warm ground, usually warmer than the outdoor cold air, and pumps this heat into the conditioned space.

The result is the need far less energy than the conventional air source heat pump system for year-round conditioning. Even in the winter, it is more efficient than conventional natural gas or oil heating systems.

Thank you very much for explaining the principal of geothermal.

It does sound like a great idea when it comes to heating your home and now my question is, how expensive is it to get the initial heat pump? Also, how energy efficient are these heat pumps?

What would be the savings monthly as compared to other heating options?
