Hi all,
Thanks for having me!
I just started reading about seasonal geothermal storage. I read alot about how efficent it all is, but maybe not since there is confusion about storage and a true system,
My first question is for example if i put a tube in the ground then fill it with hot water it will dump the heat in to the ground. as I dump the heat the surrounding ground warms up. but then winter comes and i then dump cold water in the ground forcing the water to extract and retrieve the heat which i can use, but as the heat is sitting in the ground it is radiating outward away from my pipe, so the only heat i can collect is the remaining heat that has not spread out.
If this is the case doesnt that mean that the efficency can only be 50% or less?
Am I confuseing the 90% efficency i read about with other systems?
Thanks!
