Hello everyone,

we are currently in the construction phase. Initially, we planned to install a gas condensing boiler with solar panels, but now our builder has suggested that a ground-source heat pump with deep drilling might also be interesting. He has a quote that is only 4,000 euros (€) more expensive, including the drilling.

Now my questions are:

- What are the approximate costs for the permit (building permit / planning permission)?
- Is that price even possible, or did I misunderstand something regarding the drilling?
- I have often heard that there is some risk involved with the drilling, especially regarding liability for potential damages, etc.

Otherwise, regarding running costs, I actually see the advantage with the ground-source heat pump.

I hope you can help me with my questions. Thanks.

So, you can’t just switch abruptly from a gas condensing boiler to a heat pump. You need to take a close look at the details. Information about the heating load, hot water consumption, and so on is necessary. Of course, it also depends on the heat pump itself, which model you choose. Ultimately, a heat pump requires a well-thought-out concept; otherwise, you are, to put it mildly, setting yourself up for failure. An additional 4,000 euros (about 4T€) might be reasonable, but it could also be excessive. Even if you factor in subsidies like those from BAFA, these come with specific conditions.

The permit costs were negligible for us (North Rhine-Westphalia, around 200€ I still have in mind, up to 100m² (1,076ft²)). If he offers it at that price, why not. The gas connection, chimney, and solar installation are not required. There is always a risk everywhere—what kind have you heard of?

You have to take out insurance anyway if you want to receive the subsidy.

Great, then I’ll get bicycle theft insurance. That’s also an insurance.

Could you be a bit more specific about which risks need to be covered?
