Take a 90% perfect house, which is available "off the shelf." Of course, you could try to become the winners of "Germany’s search for the best homebuilder" by splitting the process into dozens of individual threads (about heating systems, bricks, tile adhesive, recessed spotlights, gutters, locking systems, range hoods, and so on) — but in the meantime, you will lose time and money.

I would no longer recommend a heat pump. You need to understand the technology very well yourself; otherwise, it can become very expensive due to high electricity consumption. The technology is still quite prone to failure. Pressure switches, compressors, and electronics often break down one after another.
Heat pumps are heavily hyped and receive government subsidies. However, the underlying technology has existed for over 40 years. Ask yourself why it hasn’t become widely adopted.
If you have a gas line, go for a gas boiler immediately. It is affordable and reliable. Another alternative is pellet heating.
In my opinion, if you use a heat pump, you will also need a wood stove. Otherwise, you will often feel cold inside the house during winter or early spring. The heating system is too slow to meet personal comfort needs. Most people with heat pumps also run electric fan heaters or wall-mounted electric radiators, which defeats the purpose altogether.

I would no longer choose a heat pump. You have to engage a lot with the technology yourself, otherwise it will drain your wallet in terms of electricity consumption. Also, the technology is still quite prone to failure. Pressure switches, compressors, and electronics tend to fail one after another. Really? The technology has been around for over 100 years and, in my opinion, is well developed. It’s neither more complicated to operate nor more prone to defects. In addition, it requires less maintenance than a gas boiler and, if in doubt, is more cost-effective.

The heating is too slow to meet personal comfort needs. The heat pump itself isn’t the heating system; it’s the combination of heat generation and heat distribution that defines heating. The sluggishness results from using underfloor heating instead of radiators. A gas boiler also cannot heat a room faster when paired with underfloor heating. If you turn it up to maximum, the supplied heat stays in the room and it becomes like a sauna.

Sorry Bookstar, I rarely read such a “foolish” and factually unsupported post from you. This is pure polemic.
Unfortunately, none of what you wrote is correct. And this has nothing to do with polemics.
1) The technology is much more prone to defects; there are many more components that can break, and the wear and tear is much higher compared to a gas boiler. If the technology were so mature, why does Novelan/Alpha Innotec replace all pressure switches one after another? This requires completely draining the system and refilling it with refrigerant, etc. This effort alone is immense once the warranty period is over! There is nothing cheaper compared to a gas boiler. After 10 years, you’ll need a new compressor and pay several thousand euros. So your fairy tale is out of place here, sorry!
2) New buildings are equipped with these systems because they are hyped and subsidized by the government. We have such a nightmare unit ourselves.
3) Every degree higher in supply temperature hurts your wallet significantly. With pellets or gas, it’s irrelevant. You can run a 35°C (95°F) supply and regulate with actuators. Then you are much less sluggish than with air heat pumps. That’s also why we have a wood stove; I couldn’t imagine living without it. Sometimes I want 20°C (68°F) in the dining room, sometimes 24°C (75°F). With a heat pump, that just doesn’t work. With gas heating, no problem.
4) The noise issue with neighbors is not even considered. Here again, a gas heating system is miles ahead of a heat pump. Also in terms of cost.
5) Turning on a gas heating system just runs. A heat pump requires numerous software updates, needs to be calibrated (which most heating companies do not do), and is very sensitive to external factors.
Explain to me where the polemics are, and we can continue the discussion.

I am not aware of any major long-term defects.

The heat pump only needs a socket and runs.

Every degree more of flow temperature hits your wallet hard. That is not the heat pump’s fault if you don’t manage the system well. Proper planning, correct settings, and just let it run.

That’s why I have the wood stove too; I couldn’t imagine living without it. Sometimes I want 20 degrees Celsius (68°F) in the dining room and sometimes 24 degrees Celsius (75°F). So you would need that with gas as well. Underfloor heating doesn’t work like “snap, 24 degrees Celsius (75°F) achieved.” And once you reach that temperature, it takes days for it to cool down again at that level (with underfloor heating).

No problem with gas heating. Once again, this has nothing to do with the heat generator. It’s due to the underfloor heating.

The noise issue with the neighbors wasn’t even considered. Here, a gas heater is far ahead of the heat pump. Also in terms of cost. Noise wasn’t asked about. It mainly occurs during winter when the heating runs. In summer, when you sit in the garden, you don’t hear anything. Personally, I find the devices whisper quiet, but that’s subjective.
That they are more expensive, I do not see. That is objective.

Turn on the gas heater and it works. The heat pump needs countless software updates, must be balanced (which most heating companies don’t do), and is very sensitive to external influences. Maybe you got a faulty unit? If the system runs, it runs. Then you don’t need updates. And a proper design along with hydraulic balancing is standard with a competent heating engineer or construction company. For the average user, that means: turn the system on and let it run.
