Vertical Geothermal

One should never be worried about not being able to use geothermal power for their local heating. Where housing is tight, its really not an issue. Traditionally, geothermal heat pump systems will expand outwards which can create issues for tightly packed housing. Not a problem however, due to the fact that geothermal can be drilled directly vertical. Here is a picture of such a system of the Rehau Helix Probe.
