exact, but in the case of a closed and waterproof loop, it is also circulating, no need to raise, I'm wrong?
more hot water tends to rise, which should help?

if the circuit is closed, it is the style pseudo geothermal drilling with 2 pipe embedded in concrete: the heat exchange with the ground is weak, the exchange is the same with the bottom which is hot that with the top which is cold ... it would be necessary to isolate the top
Geothermics is good in Iceland where there is a sheet of water more than 100 ° and not even need to pump it is already under pressure!
in the case of pseudo-geothermal drilling, we draw a large power because we accept more than ten degrees of difference in the soil and the temperature supplied: it is the heat pump that compensates for it is a drop in temperature
to produce energy the slightest drop in temperature makes everything lose
