Geothermal heating

[Lightspeed]

I'm starting to investigate Geothermal heating for the retreat.

Idea is to install Geo therm bore holes and to use PV to power the pumping and heat exchanger. This is great in theory, but I need to understand the relative power requirements to see if its actually viable.

I can't find anything on here about it.

Have any members got any info they can share with me? I'm thinking that maybe, before starting my own research, someone else on here may have already gone down this patha and could share what they've found with me?

If indeed there is no info here, I'll post what I find at a later date.
