[edit] Redundancy and article purpose

This subject is already covered in geothermal heat pump. I think that geothermal heating should be changed to an article about using relatively hot areas for heating rather than just using the Earth as a thermal mass for a heat pump system. This is what I think of when I hear "geothermal heating". Probably the most common way to use geothermal heating is through district heating systems. They are used to heat homes in Iceland. -- Kjkolb 12:14, 8 December 2006 (UTC)

I added an introductory paragraph to generalize the article to cover multiple types of Geothermal Heating. --David Bangs, 5/29/2007

[edit] Incorrect Explanation

The claim that Geothermal Heat Pumps utilize the higher temperatures available below the surface is completely incorrect. The pipes may be buried just a foot or so down and the earth is useful for heat conductivity and stability. A given heat pump can both cool or heat a house in any location by acting as a refrigerator or reverse refrigerator.

The description of Heat Pump action here is almost entirely incorrect.

[edit] Worldwide underground temperatures?

Normally the earth temperature is around 12.8oC (or 55 °F) at depths of 10 ft.

Worldwide? Even near the equator? Is there a map of global underground temperatures? Glueball 18:27, 14 February 2007 (UTC)

55degF is what the subsurface ground temperature is at the approximate latitude of Delaware, it certainly is not the same worldwide. And yes there are some rather detailed isothermal maps showing the ground temperatures for various locales across the U.S. --Garyonthenet 05:07, 18 May 2007 (UTC)

[edit] links

here are some links that i think should be added to this page. I'm new to the editing process on Wikipedia, so if someone could help me out with getting them approved, i'd appreciate it. thanks!
