How deep is the ground temperature?
At a depth of 4 to 6 feet below the frost line the ground temperature of the earth remains relatively constant throughout the year. Ground source heat pumps (GSHP) are designed to capitalize on this near constant temperature.

How deep should geothermal wells be?
Coming to your answer, if your area has geothermal resource then you need to dig at least 2 to 3km deeper wells in order to get benefits of geothermal resource.
How deep are ground source heat pumps?
Ground sourced heat pumps, which involve laying pipes in trenches a metre or two deep, with the output dependant on the area covered, or comparatively shallow drilling into a water table which can provide ground temperature water for heat extraction.

It depends on the area and site. Normally, there is 25 degree celceus rise in temp per km deep dig. Some areas such as Iceland or the countries near by ring of fire contains ample amount of geothermal resource.
How deep can you drill for OT water?
If your looking for ot water, you could drill for miles and not find it. There are gold mines over two miles deep that do no contain ‘geothermal water’. Temperature rises about 10 degrees F per 1,000 feet in normal rock. Geothermal fluids are abnormally hot water and are generally associated with geological recent volcanic rocks. You will not find hot water at shallow depth in the majority of the Earth’s surface.
What is the second approach to extracting water from volcanic rock?
A second approach is direct heat extraction which work extremely well where the gradient is higher. In volcanic areas hot water and or steam can be extracted from extremely shallow depths.
How deep can you lay a pipe?
You can lay pipes as little as 1 metre deep but this way requires a large surface area. Remember this is about compressing slight variations of temperature to create a larger one. Wizardry, I don't quite understand myself!
How deep should geothermal lines be?
Geothermal heating works because the temperature under the ground doesn’t change no matter how cold or warm it gets outside.

What is geothermal heating?
Geothermal heating makes a viable alternative to more traditional forms of heating. It uses the ambient heat in the ground itself to facilitate an exchange: running tubes full of liquid through the ground which can both transfer heat into the earth and pull it from the earth, depending upon what you need. Here in Raleigh, geothermal heating systems ...
