First of all, the vast vast vast vast majority of geothermal heating is NOT done by drilling down to find water hot enough to heat your home.<quoted text>
You didn't anser the post, dufus. Here it is again:
Like you really understand what you posted.
I'll put it to you simply:
Geothermal heating is a piece of cake. Just drill a hole to the temperature you desire, and circulate water through it and throughout the building.
Geothermal cooling is very difficult. Why? Because the heat you transfer from a building to the ground has to be transported away from the location of the building, or it just rises back into the building.
How about this one:
How is the heat transported away from the location of the building after it has been transferred from the building to the Earth immediately below the building?
... your turn, dufus.
This shows how ignorant you are on the subject of Geothermal & the temperature of groundwater.
Second, if you heat your home with this mythical hot water, it would be returned cooler. Just like using cool water to cool your home would return water that is hotter.
In both cases, the return water would need to be returned to the original temperature. This is down by the temperature of the earth where the discharge is made. No need for aquifers to return the water to original temperature.
But hey, thanks for the laugh on your version of geothermal heating.
