Air-water heat pump current consumption and data

Or the devices become more efficient with consistently moderate planning. Maybe 38/24/3 is no longer set but 31/22/0 after all.

The result is in any case that the air-water heat pump can easily operate between 3.5 and 4.0 and the brine-water heat pump between 4.5 and 5.0. For that, I then don’t need gas, pellets, or anything else.

That is too theoretical for me. Only people who are interested enter data into such a database. Certainly, 90% of the bad systems do not appear there.

Yes, of course, the sample is not representative. But the development within the sample still holds. Unfortunately, we cannot verify to what extent the observation is transferable to everyone.

No question, I have known the database for a long time as well and it is also interesting to browse through it. Undoubtedly, the systems are becoming more and more efficient, that is simply the advancement of technology. But one must not forget that other heating types have also improved massively, for example, pellets. Much more reliable, energy-saving burners, etc. So far, there is still no ONE heating technology for me. They all have advantages and disadvantages.

Wrong. When you retrieve the individual values, there are also terrible values included. But I find the insight much more important – and this is practice, not theory – that it is perfectly possible to achieve very good values. But those who spend months thinking about which new phone to get or how to ideally plan the last centimeter in the house (every little detail is debated here on the forum), should also be able to spend an hour philosophizing about a heating system. Because the planning is actually quite simple, you just have to plan and not build by guesswork. And it is also apparent that the values have improved over the years. After all, more than every second newly installed heating system is a heat pump!

At least more than every second newly installed heating system is a heat pump!

I happened to read yesterday that it is even 77%. The figure is said to be from the year 2019.
