Hello, we are currently planning our single-family house of 165 m² (1,777 sq ft) in the Sauerland region.
We want to build using 36.5 or 42.5 cm (14.4 or 16.7 inches) hollow bricks without additional insulation, as we are not fans of external thermal insulation composite systems (ETICS). Underfloor heating is planned, probably no ventilation system, as it is too expensive.
Since the village is not connected to the natural gas network and we have no basement, therefore no space for, for example, pellet storage, we have to install a heat pump.
A ground source heat pump would cost €4,500 more after deducting the BAFa subsidy compared to an air source heat pump.
I have also often read that heat pumps do not make sense with monolithic construction.
What would you recommend?

With photovoltaic panels, a heat pump, and an optional ventilation system, a house is modern and future-proof and can largely operate without fossil fuels. There are certainly alternatives, but in my opinion, gas tanks and solar thermal systems are not among them—especially not in new construction.
Ventilation is a comfort feature, photovoltaic systems pay off on their own, and heat pumps should be carefully planned.That sums it up completely, except for the addition that a ventilation system provides a huge comfort benefit.
A house with pellets is just as viable and future-proof. However, the most economical option is still gas combined with solar.
Above all, heat pumps are not very durable, and the technology is not fully developed, especially inverter-controlled systems.
So, there are many opinions regarding heating technology, but the one in the original post is definitely incorrect.

The statement about what is most economical is a "it depends." Saying gas is always better is just as wrong as saying heat pumps are always better. Similarly, the claim that air-to-water heat pumps are not durable is a rather strange statement, which is at best suitable for informal chatter.
Okay. What sources are you using to support your statement? Tip: The neighbor knows someone who heard... is not a source.
It’s ALWAYS a case of it depends.
Heat pumps have been around for a very long time.
On the other hand, there are manufacturers of gas heating systems where a non-replaceable component led to the need to replace the entire heating system after about 10 years.
At informal gatherings, you mostly get opinions. Rarely facts.

However, a heat pump is usually replaced faster than a gas boiler. But that doesn't help the original poster.
I would recommend an air-to-water heat pump with a central ventilation system. Then you would need to save money elsewhere to afford the ventilation. Under no circumstances would I rely on trickle vents in the windows (casement window vents). You don’t buy airtight windows only to put holes in them again.
