Hey all! long time lurker:
I've been interested in geothermal since I was a kid. I've recently been reading a lot about the different types of well systems and I think I'm most interested in a closed loop system. I know horizontal is constrained most by land availability, but the locations I would consider deploying a well don't have the concern of scarcity.
Touching on related interests: I also read a lot about home agriculture and what could work in my climate and what benefits there are to different building approaches towards green houses. I learned about GAHT which recycles the heat generated by plants to self produce a desired climate.
I also read a good amount about different home building techniques and approaches, most of which center around having a relatively air tight thermal envelope. For this reason, it almost never makes sense to have a fireplace in my region.
I guess what I'm wondering is twofold:
is there some magic arragenment that marries geothermal and GAHT systems?
if you produced excess heat in the winter on a horizontal loop that is buried beneath the frost line but shallow enough to warm the earth below, say, a greenhouse, could you reasonably transfer heat from a fireplace either indoor or out to the green house.
Thanks for reading!
