The technology is significantly more prone to defects; there is much more that can break down
It is just as prone as the refrigerator. If parts break down one after another, there is a design flaw. You still drive a car despite all the recalls. I am not aware of any significant long-term defects.
Cheaper compared to a gas boiler is nothing here, after 10 years you need a new compressor and pay several thousand euros.
... except for the annual inspection and maintenance, the gas connection, the chimney (actually just the exhaust pipe). The heat pump only needs a power outlet and runs.
New buildings are equipped with it because it is hyped and state-subsidized.
The subsidy is even newer. Hyped because it is a great product, for a long time already.
Every degree more supply temperature hits your wallet massively.
The heat pump is not to blame if you can’t handle the system. Plan properly, set correctly, and just let it run.
That’s why there is also the wood stove; I couldn’t imagine without it. Sometimes I want 20 degrees in the dining room and sometimes 24 degrees.
So you would still need that with gas. The underfloor heating doesn’t just go “snap, 24 degrees are there.” And once you have the temperature, it takes days for it to go down again (the temperature reached through the underfloor heating).
No problem with gas heating.
Once again. That has nothing to do with the heat generator. That is due to the underfloor heating.
The noise issue with the neighbors is not even considered. Here too, a gas heating is miles ahead of the heat pump. Also in terms of cost, by the way.
Noise was not asked about. It mainly occurs in winter, when the heating is running. In summer, when you sit in the garden, you don’t hear anything either. Incidentally, I personally find the devices whisper-quiet, but that is just subjective. That the devices are more expensive, I do not see. That is objective.
Turn on the gas heating, it runs. The heat pump needs dozens of software updates, must be balanced (which very few heating companies do), and is very sensitive to external influences.
Did you maybe get a Monday device? If the system runs, then it runs. Then you don’t need an update either. And a reasonable design as well as hydraulic balancing is also standard with a proper heating installer or construction company. For the average consumer, that means: turn on the system and let it run.
