Holy shit where do you live??
Urban setting in eastern Canada.
It was about 30k all included. Maybe 23k after subventions.
Got rid of the oil furnace, and it now costs me about $650 for heat and AC for the whole year.
And the old furnace did not do AC.
It's been about 4 years and the return on investment was initially planned at around 10-12 years in... But that was when oil was $0.80/L and it has more than doubled last I checked.
Rather simple really... vertical well routed to a heatpump installed where the old furnace was.
More than the savings, it is much more comfortable as the temperature is more stable, we now have AC for the summer, there's no smells, no refills, barely any maintenance other than air filters... 10/10 would recommend.
So the geothermal part is needing access to a well and using ground water for cooling?
Isn't there a risk or liability for if there's a leakage?
Sounds amazing though nice going
I'm looking at heat pumps for houses. Using those outdoor radiator things powered by electricity. Geothermal sounds fancy but it makes sense.
Modern geothermal heat pump systems are almost always closed loop, you just run a bunch of loops of tubing in a big trench that's deep enough to not freeze over the winter, or if you're space constrained you use a deep borehole or 2 with a tube running down and back up again.
