I think the importance of finding a pump that works well in your house is more important than choosing the most efficient one on paper…
I have been tracking consumption for a few years, and I had a Panasonic HZ25ZKE that just didn’t work here…
The month is almost finished, so still some cold days to go, but the consumption, temperature (in 30 minute intervals) and humidity for January 2025 and 2026 (so far) has been analyzed with AI.
The Daikin Comfora 35 that was installed in the bedroom in 2019 for cooling and moved in December last year to the kitchen has been 15% more efficient than the Panasonic with a temperature that has been 2.6 degrees colder. This should give an increased heating demand of 12-15%.
The conditions have been the same in both months, trying to keep 22.5 degrees inside the house, 122 square meters heated.

Mitsun RW:lle tulossa ennätys mutta ei taida mennä tonni rikki. Mutta kun laskee lisäksi pari muuta pumppua (mm autotalli) niin menee kevyestikin.
Eilen piti aloittaa leivinuunin lämmitys kun näyttää että pakkasjaksoa riittää hamaan tulevaisuuteen.

Daikin P40 268 kWh. On se mukavasti nakertanut kaukolämmön tarvetta (kiinteähintainen sähkösoppari).
Daikin may have the best hardware but it still lacks mastering the software side. I would imagine that there are households where the Daikin might be the most efficient choice but then there are places where Daikin doesn't work properly due to it's software (mostly because of the CDP, a.k.a Cold Draft Prevention).
Nice info though!
I believe if Daikin would have dropped the CDP or at least let the user turn it on/off, add a connector where you can connect an external thermometer, it would be even more efficient.
The pump is placed in the corner of a large kitchen and is blowing the air to the living room through a large «two door opening». Not at all ideal, when the pump is at fan 4/5 I can under certain circumstances notice that it drops to 3/5 which messes with the temperature in the rest of the house (not much, but the sensors pick up the difference).
It also has a narrow air outlet which spreads the air in a better way in my scenario. Just like the Mitsubishi, the Panasonic had a very wide airflow outlet which was difficult to manage.
I’ve had to fiddle with the vanes to find the most ideal position (which was maybe found 2 weeks ago), and I’ve noticed it has a very big impact on the comfort and consumption.

Have you verified this data? Could be just pure hallusination
Yes, consumption is recorded via a z-wave device on the pump circuit. If there are any deviations because of the device, it should be there for all of the measurements. If anything it’s in the Panasonics favour as I believe the device fell out on some occasions last year and didn’t record a few hours…
If you look at the Panasonic thread you will see I had several issues with the pump and I also believe the increased consumption is just because it caused uneven temperatures in my house.
