Air-water heat pump current consumption and data

The problem is, we now have to ventilate the warm air out because otherwise it gets too hot inside. At the same time, the heat pump is running. Quite absurd!

I see the same with my neighbors: heating on, blinds down, or windows tilted open. I'm just not willing to do that because it's so absurd! That's why the venetian blinds are up.

I recently read an article stating that most heat pumps do not achieve a COP of 3 and are uneconomical. That was balm for my criticized heating soul, since my system delivers between 3.0 and 4.0 :D

I would sign that immediately without having researched it. Very few, if any, home builders have dealt with the planning of the heat pump and the design of the underfloor heating. Neither have I. Therefore, you can basically only optimize afterwards, but not comprehensively. And it's only one pillar. Many people whose heat pump runs moderately but who are satisfied don't look at the unit again until after a few years something doesn't fit and breaks. A neighbor has the same unit as I do and now, after 5 years, has a defect in the domestic hot water preparation. That was only noticed because I complained about my heat pump and the spread, and we exchanged thoughts.

That's why I also said yesterday that it will probably be too warm for Tom today.

That's right, we are approaching 24 degrees, the heat pump is currently taking its first break in 24 hours. The electricity meter shows 30 kW even though the heating element has been operating for 24 hours, probably just a slight support.

the study is available from the Fraunhofer Institute

On this topic, I always recommend the consumption database for heat pumps (easily found by googling). These real values from users (who, together with their heating technician, give more thought to their heating) provide realistic and well achievable values. What is striking is the continuous improvement over the last few years.

Doesn't that suggest that more and more Heizis are actually learning?

Or the devices become more efficient with consistently moderate planning. Maybe 38/24/3 will no longer be set, but 31/22/0 will still be set.
