First of all, only you thought I was talking about extracting water, idiot.<quoted text>
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.
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.
To begin an elementary understanding of geothermal HEATING, learn what a conduction system is. Then, learn what a closed system is.
Now, back to what I was initially discussing, the most significant consumer of electrical energy, cooling.
Note, again, the use of a conduction closed system.
Please give yourself at least an elementary knowledge of thermodynamic applications before you ignorantly reply.
And it would help if you actually read the description of geothermal cooling in the post. Where the f**k you got onto geothermal heating, who knows.
Now, apply a closed conduction system as a means of transport of heat from a building to the Earth. Then,.... tell us what will happen if that heat isn't transported to some other goddam place other than directly beneath the building where the ehat came from.
... goddam idiots.
