TL;DR: It's kinda like a watercooled heatpump that uses the earth as its heatsink.
It's not actually using ground water though. Although such systems exist (open loop), mine is a closed loop.
They dug an 8 inch wide hole, 300ft down.
They then put a loop of polypipe that goes down to the bottom to a heat-fused U joint and then back up.
The free space in the "well" is then backfilled with bentonite (clay) to maximize thermal exchange between the loop and the ground.
The bentonite also swells when in contact with water, so it might help mitigate smaller leaks, but don't quote meon that.
The pipe is filled with a mix of water and glycol to make sure it can't freeze and a pump takes care of circulating that to the heatpump, but there's no fluid exchange between the loop and the environment.
AKA Closed loop.
A traditional heatpump is an air-air heatpump, a geothermal heatpump is a water-air heatpump.
Basically, the advantage of the geo heatpump is that the liquid comes back out of the loop and into the heatpump at about 7 degrees C all year.
It is much easier for a heatpump to heat your inside air to 22C by extracting heat from a 7C liquid than from -30C outside air.
Similarly, cooling your inside air by dumping heat into a 7C liquid is easier than by dumping it into +30C outside air.
The heatpump itself is installed inside where the old furnace was, which means it's also more protected than a traditional heatpump that's installed outside, hopefully increasing its lifetime.
Don't get me wrong, traditional heatpumps are also great and might a great fit on lots of places.
Having (some) pretty cold days up here, we went with the geothermal and it is more than sufficient year round. The only times the aux heat kicks in is when I test it manually.
That's probably your app's UI being more confusing than it needs to.

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.
You'd think with all the cereals we're producing, it'd be ubiquitous, but all the stuff at the grocery store was either Kelloggs, Kraft, or General Mills.

There seemsto be a few more options out west than here in QC.
I already get granola from a small local place which is great, but surely there's a Canadian version of corn flakes or rice krispies or whatnot somewhere.
As some of you may have noticed, there's an instance with 1.1M bots reposting reddit posts and comments accross communities in several other instances.
I expect there are multiple valid opinions on the subject and this thread is meant to get a feeling of everyone's opinion on the situation.
You might also want to read lemmy.ca's discussion on that here which is a pretty decent thread about the subject.
Things that I think need to be pointed out:
alien.top currently has 1.1M bots, only 6 of those are weekly users logging in.
together they've made 1.59M comments accross a multitude of communities in other instances.
That project claims to be trying to get reddit users to switch to lemmy.
They have a portal to allow reddit users to claim and take over their bot persona.
alien.top has a single local community, the bots all post on different inst

In a monumental achievement, Bangladesh has become the first country in the world to be officially validated for having eliminated visceral leishmaniasis, commonly known as kala-azar, as a public health problem.

Kala-azar is a deadly parasitic disease that's also known as Black Fever, or Visceral leishmaniasis.
It is the second most deadly parasitic disease (after malaria).
