You can have geothermal power everywhere if you drill deep enough

Awesome! Do you sink heat into it during the summer, or do you also use it for airco?

Sink directly into it for the summer. Heat exchanger between the source (approx 10-15C) and the water from the floor heating/cooling system. Because the heat pump is not involved it's very efficient (only the power of the well pump)

I'm actually considering if it makes sense to push a lot more heat into it in the summer (Deliberately leaving curtains open, then moving this heat into the well; or even PVT panels), but I'm not sure if the well would retain heat long enough to make a difference towards the winter.

It definitely should, I'm not sure making your A/C work harder deliberately makes sense economically, I guess you'd have to do the math. PVT or even just thermal panels (i.e. rolls of garden hose painted black in a glass covered box) would make a lot of sense if you're in a colder climate though.

Your system should give a an overview of your yearly input/output and any drift of the well temperature right?
