The discussions in the threads about heat pump consumption and supply temperature settings are full of technical terms, values, and configurations. It is sometimes mentioned that installers pay little attention to optimal adjustments, and that one should be more careful during the system design phase. From what I understand, incorrectly sized and/or poorly adjusted heat pumps lose their economic advantages. Therefore, I have three questions:
1. How much knowledge and skill does a homeowner actually need to acquire in order to achieve the cost-effectiveness they expect from their decision?
2. How likely is improper use by inexperienced users who simply want to have a comfortable temperature in their home?
3. What habits does a person need to give up when living for the first time in a house with a heat pump in order to achieve the expected cost-efficiency?

I don’t want to disrupt the peace and had to smile a little at how things developed, but I also have to agree with Alessandro’s initial statement (and I suspect the task was somewhat satirical, though I don’t want to make any assumptions...).
The calculation above only holds true if we assume a completely dumb system—consumers and the power grid with no communication. In a smart system, it is actually much more beneficial for the grid operator to have temporary but registered and/or controllable individual consumers, rather than having to increase the base load across the board. With numerous different consumers of significantly larger scale, it is quite possible through time-based control to connect more consumers (such as heat pumps) to the grid without raising the base load.
Put another way: Every heat pump running continuously inevitably increases the base load (and therefore also the peak load), whereas every controllable/smart heat pump (even if it has higher output) has the potential to be used without impacting the base load.
Whether this actually works in practice and whether our grid will become smart enough, or if grid operators just want a point of access into the home, and to what extent the ERR has truly been considered—of course, that is another matter. What is clear, however, is that with a smart grid and temporary consumers, base and peak loads can potentially be reduced, while permanently operated consumers inevitably increase them by principle.
