Infrared heaters throughout the entire house?

I really don't know what you have against smaller houses. You bash them at every opportunity.

You have to explain to me in more detail where you managed the feat of reading a dislike of small houses or even bashing them from my posts :-(
On the contrary, I criticize when people design houses where each single floor is already as large as their wallet would actually barely allow as the total size.

I understand it like this:
He has nothing against small houses – rather against planning a house (here quite modest in size) with features that are usually “expected” in larger houses, meaning because the investment is more worthwhile per area. A lot of technology also means a large roof area and a big freezer room. That conflicts a bit. As I have already noted, it seems as if half the house is either equipped with placeholder rooms or with auxiliary rooms.
Moreover, the energy savings, if one approaches it sensibly and ecologically, should also be usable by more people.
If you take it precisely, you choose a storage system designed for so many people. Then a heating system that fits the household and the daily routine. (Let’s leave infrared heating out of this translation, since is speaking more generally)

So another, simpler example: there is no point in a single person installing a family bathtub in their bathroom. Even if they like to take baths and occasionally a second person bathes with them, one should plan for up to 2 people, not a corner tub for 4, where then a shower fixture is added in case someday 3 people..., etc.
And then there is the question of needs: why plan this and that as if configuring a new car, where certain financial aspects don’t matter, such as sports equipment, ashtray, etc... but it’s doubtful whether a Dacia needs a Porsche engine.
Certainly you can do it, but somehow it’s quite pointless. Just for the sake of wanting to have it?!

Running it with an air-water heat pump is just "tough". You don't need a heating rod either. But these heat pumps require ultra-low flow temperatures, especially with such a high desired room temperature, otherwise you'll pay through the nose.

That requires proper planning. Nothing more, nothing less. It should be the norm. And a normal flow temperature should be a maximum of 30 degrees with Siberian cold for a heat pump. It doesn't work with 15 cm underfloor heating loops following the motto "We've been doing it like this for 20 years".

Yes, certainly that is the be-all and end-all with this technology, which simply has conceptual disadvantages compared to combustion-based heating technology. A heat pump will always fall short in terms of comfort; without a wood stove, you can forget such a thing in my opinion. For that, I then also have a chimney and a chimney sweep... Good planning only keeps the running costs somewhat under control, provided the electricity price doesn’t skyrocket even more. If heat pumps weren’t politically favored (like e-cars), they wouldn’t have become widespread either.

As always, nonsense what you write about the heat pump. Comfort has nothing to do with the heat generator. And an additional wood stove is nice for coziness, but unnecessary as a heat source.

... and would not have been in use for 100 years, nowadays mostly installed in new buildings. Not even as air conditioning. The devices are rubbish too. And wherever heat pumps are installed (cars, dryers, etc.).

Nonsense is when you ignore technical features and physical realities. Every degree higher in supply temperature costs a small fortune with a heat pump. The pellet heating system couldn’t care less. Higher supply = faster responsiveness. A spread of 24 degrees in the bathroom and less in other rooms can also be well regulated by actuators with pellets. A heat pump is extremely sensitive there and causes a lot of problems if in doubt, either it doesn’t get warm or efficiency drops drastically. Then there’s also the hot water issue or rather the risk of legionella...
