Dear AC Hacker,
Your quote on the ground source technology prices are sadly true. I m building my own home which is a flat on top of my parents house. with prices sky high of fuel oil and electricity; boilers, electric heaters and DX units are not economically possible for 80% of population in my home country ( Jordan ).
I m crazy with geothermal idea, the first estimation i have got from the installers is about 40K USD.
the majority here wont save this much during entire life.
further please share the study cost for the building and running such heat pump.
I highly appreciate if you can share guidance with me please. as I m planning to make a prototype.
Best Regards
Jibreel
