ᐅ Air source heat pump with fireplace, hydronic stove, domestic hot water heating

I have already read through several forums but haven’t found a satisfactory answer. Hopefully, someone here can help me:
We are planning a new build (single-family house, 130m² (1400 ft²)) and are unsure which heating system to choose. Since we plan to mainly heat the ground floor with a fireplace, our idea was to cover the remaining heating demand with an air-source heat pump (due to lower initial costs compared to other heat pump systems). In any case, we want to be independent of gas or oil! You often read that air-source heat pumps are not necessarily the most efficient heating systems, but in our case, it will mostly be used as a backup heating and for hot water supply—or am I mistaken?
Who has experience with the heating system mentioned above and can recommend an air-source heat pump? Or does anyone have an alternative suggestion for an AFFORDABLE heating system?
Thanks for all the answers!

The fact that this technology forces a neighbor to take action already disqualifies it in my opinion.
I believe everyone should do what they want, as long as there’s enough space. But just look at the new housing developments—plots of 400 cm² (4305 ft²), all packed tightly together.
Now if just one person sets up their system incorrectly, or who knows, these things tend to get louder over the years... like server fans and air conditioners do, too.
That’s when trouble starts.
Some people live next to a highway and don’t mind, but others can hear even a faint humming. For example, I hear that kind of noise and it drives me crazy.
We just recently built a new house, and it’s so quiet there you could hear a pin drop. Fortunately, I have 800 cm² (8611 ft²) of space around me free from any technology. I’d probably feel disturbed if such a device was running right outside my window.
Although with modern buildings, people often don’t even open the windows anymore.

... I can only advise against installing such a noisy power hog unless you hate your neighbors.
Wombel A completely wrong conclusion! Especially calling it a "power hog" is absolutely meaningless! It is undeniable that air source heat pumps generate a certain level of noise. With appropriate ambient background noise, this usually doesn’t matter much. In very quiet locations, however, it can be more noticeable. In such cases, you can choose indoor units, although these unfortunately are not fully modulating. Outdoors, fully modulating split units only cause noticeable noise at very low outside temperatures, if at all. Unregulated evaporators, however, can indeed become problematic. In very quiet locations, especially in colder climates, it may be advisable to avoid air source heat pumps in favor of ground source heat pumps.
Here we are dealing again with specific, individual, location-dependent conditions. No building project is the same as another. What makes sense for A might barely work for B and turn into a money pit for C!

Good evening, my neighbors built their retirement cabins (I think more as an investment) for 15 years from now! This means they are there at most on weekends, but their air source heat pumps run around the clock. I’m actually on friendly terms with the neighbor right opposite me. He even adjusted his air source heat pump so the noise no longer blasts directly against my house facade, though I could still hear and feel the noise with the windows closed! Still, especially at night, the noise level is unbearable, since otherwise the only sound is usually an owl.
The technical guidelines for noise were developed for industrial areas and are only a recommendation. A noise level of 35 dB was measured in front of my window, so it’s within the “standard limits.” That might be comparable to the background hum of refrigerators, but just imagine sleeping in a room with a refrigerator constantly running… 24 hours a day, for the rest of your life. Trust me, you do not get used to that noise; it drives you insane over time.
Now the neighbor wants to put up concrete sound barriers—whether that will really help? What a hassle for such a ridiculous heating concept… and when that thing runs day and night, it also consumes a lot more electricity than is reasonable. How is that supposed to compete cost-wise with my basket of firewood??? I expect to spend around €600 per year on heating (without water), which my neighbor definitely won’t manage, even though his bungalow is about 100 m2 (1,076 sq ft)… our house is 110 m2 (1,184 sq ft). AND they have certainly taken a big slice of quality of life away, and I’m fed up with having to listen to when the neighbor is heating… so unnecessary.
