I have heard of geothermal and discussed it a little with an engineer that I was talking to. He said that basically it is a duct system if you will that is placed in the ground at a depth where the temperature stays around 68 degrees. The air is then circulated through your house during the summer to act as AC, or in the winter it is circulated as heat.
The postings I'm seeing are talking about water.
My neighbor had a system put in and they dug a trench in a U shape that is approximately 200' out and then 200' back. Is this a geothermal system? Where does the water come in to play. I have also heard of solar water heating systems where they run water pipes on your roof and it supplements your hot water or warms your floor.
Can someone give a basic description of how all this works.
