Dear forum members,
I am planning to build a single-family house with a heat pump and want to carry out a deep drilling for this purpose.
Problems in my view – possible legacy issues from mining (Ore Mountains).
In another post, I also read that the local water authority has objected:
“Now the local water authority has thrown a wrench in the plans and does not allow deep drilling.”
Therefore, I would like to know where problems generally arise and how these can be identified early and avoided.
Best regards,
Florian
PS: The construction company believes that deep drilling would not be problematic.
PPS: I would prefer not to be surprised by insurmountable problems after the planning process.

When it comes to things like pipe thickness and installation spacing, I simply trust my company, which has been doing this for decades, has a solid reputation, and especially regarding heat pumps, already planned to implement all the well-known advice from forums on their own.
At some point, I just don’t feel like approaching people with self-taught knowledge anymore.
No offense to you – it’s just a really tricky situation now because you’re making a lifelong decision.

You’re right – I would have preferred it differently as well. Unfortunately, the general contractor has rather little experience with heat pumps, but otherwise he is good and works closely with the builder (although contracted separately). The advantage is that our site manager gets along well with him and everything is organized and coordinated quickly – the downside is that he has little experience with heat pumps and was actually relying on Vaillant. They really messed up their calculations. And then the forum comes in with its tips.
I just hope that, in the end, everything will work out – we’re not going in completely blind, just a bit confused.

So. Now we have the permit, but the drill isn’t coming... so dry heating with electricity – according to Vaillant, no problem, just more expensive. We will also have 130m (430 feet), but split over two drillings, since more than 100m (330 feet) is not allowed (which unfortunately will also make it more expensive).

On our side, the drilling rig arrived Friday morning and reached 140 meters (460 feet) around noon, and by the end of the workday the borehole was sealed again.

So, hopefully once the drill arrives, things will move quickly – but the vehicle is apparently going to be stuck at a large construction site in Osnabrück until the end of November -.-
A bit of a frustrating situation.
What annoys me even more than that is the offer supposedly for 6 kW – calculated with 50 W/m, which we unfortunately don’t achieve here (it’s only 39 W/m). That’s why the extra meters and quite a steep surcharge – plus the fact that we still haven’t received an updated quote or any confirmation on when the drilling will actually take place...
I think, if necessary, we’ll go with trench collectors (if I can find someone who knows how to do that).
