I've got wells on my property. Rather than drill more wells, I am wondering if there's something that could be put in the well to utilize the stable water temperature down below to heat exchange? Seems like there would be a big market - lots of people on wells are heating with oil or propane or electricity at massive costs.
It would depend on the well and the “heat availability” (not a technical term) and how deep it was.
I suspect it could work but it’d be marginal enough as not to be worth it compared to straight air heat pump or an actual field (similarity could a heat field and a septic field be installed at the same time ,,,)
I understood, perhaps incorrectly, that the ground below the frost line is stable year round and if air source heat pumps work more efficiently down to -10C, we know the water isn’t that cold (otherwise it would be ice), so wondering if the efficiency threshold is the same for ground source heat pumps?
