Geothermal underwear? Is that like the new Under Armor? Wait, geothermal is under the ground…I get it.

I saw a commercial on tv recently promoting geothermal heat. Where I live oil heat is still the predominant source of heat for many homes. It is expensive, NOT earth friendly, and quite frankly prehistoric.

So the geothermal commercial intrigued me to find out more about this efficient, green heating system. Here is what I found out.

Apparently in Maine there is a way for homeowners to get 30% of the installation cost put towards a tax credit. Sounds good but is it worth it?

This is not a new concept by any means. Humans have been using the earth’s own heat in productive ways since the Paleolithic era, think hot springs. There are many left over minerals and solar energies that were absorbed when the earth was formed. The decay of these minerals is a little radioactive. So the decay along with the solar energy that is absorbed at the surface creates a heat that can be used to heat our homes with the help of a heat pump.
