Hello,
It would be really great if everyone here could just post one or a few pictures showing the current state of their house.
I'll start right away.
For renovations, it’s best to provide a comparison of before and after the remodeling.

Yes, technically it is hard to understand since neither sunlight nor precipitation reach there. Where does the regeneration come from?
A wooden cellar is also interesting, because if there is ever water intrusion, how can it be repaired? Is it watertight in the long term, over 20 years? And so on.
But I don’t want to unsettle you with this; experience shows that it apparently works.

The manufacturer of the membranes offers a 50-year warranty (which is more than enough for me at 51 years old; after me, the flood), but only because legally that is the maximum allowed. In reality, they probably last much longer.
Experience with these membranes goes back 35 years now, but only above ground. If they are underground without exposure to light or other weather conditions, their durability should be even better (judging by the plastic sheet we dug up that probably has been buried since my parents’ house was built, I have no concerns at all; it looks like new).
The pipes lie in sand, which seems to be crucial. I don’t know the technical details; I simply trusted the practical experience.
In summer, the excess heat from the solar system is carried through these pipes, warming the surrounding soil (at the mentioned daughter’s place, the ground is now around 24°C (75°F)).
I can ask again for more detailed information at the next meeting. As a layperson, it all made sense to me, although I must admit I had never heard the idea that it “needs sun and rainfall” before.

Differences in temperature compared to the case without a building permit / planning permission (BP) on top could be compensated by a larger collector area.
This is roughly my theory. Otherwise, I don’t see how it works.
The fact that it is installed in sand, in my opinion, supports this.
