Bookstar can handle a bit of teasing. The few cents with the outside temperatures are okay. Although I cannot distinguish here between my on/off heat pump and the modulating parts. What do your module heat pumps consume at the lowest setting? Also, the temperatures + rain are extremely good for the garden laid out last year.
Nibe F730 at the lowest compressor frequency (20 Hz): approx. 260-280 W
NIBE F730 at the lowest compressor frequency (20 Hz): approx. 260-280 W
Hm… I find that quite reasonable. During the transition period. With storage and photovoltaics, one wouldn't need to manually increase the return temperature at 280Wh. At least I wouldn't, if I had a modulating heat pump.
So, I finally have an electricity meter not only for the compressor but now also for the control electronics and circulation pump. In June, the heat pump finally stopped heating and only produced hot water. The amount of heat generated in June was 124.4 kWh, electrical consumption 35.1 kWh (of which compressor 29.4 kWh and electronics/circulation pump 5.7 kWh). COP=3.54. I am satisfied with that. Now I am looking forward to the next heating period.

Wow. That sounds very low to me. How many people are there? We are significantly higher.
But I must also admit that we shower a lot.
I also find the amount of heat supplied extremely low, especially since the heating operation was still running at times. I would also be interested in the basic data on hot water consumption (limit temperatures, storage size, number of persons, circulation yes/no)
