I see it the same way as you, but I can’t change it anymore. I should have stood my ground against the heating installer, who insisted on installing the bigger one...
Circulation only runs very briefly during the day, max 1 hour.

Hi!
1 year has passed...
I have consumed 2800kWh hours and paid 560€ for the year.

When the heating was off, I had a consumption of 2.6-3.5 kWh/day.
In winter 12-16 kWh/day.

I turned the heating on two weeks ago, but first lowered the set temperature by 1 degree.

Hey,

does anyone happen to have a Rotex /Daikin HPSU Compact Ultra?
It would be great to see how the settings are supposed to be roughly. Somehow I'm still struggling with it. For example, right now the outdoor unit is "on". Does it even make sense for it to be running at this late hour when it's cold outside?
Maybe someone can be found – happy by PM – to go through it together....

When else is she supposed to work? The colder it is outside, the harder the heat pump has to work, because the heat losses of the envelope also increase as the outside temperature decreases and the heating system has to compensate for them.

I think he thinks she should work during the day, as the screed & co can then charge more efficiently and draw on the stored heat overnight. The control of the heat pump would therefore need to know that it gets colder outside at night and use the even warmer air as a source. Whether that adds up mathematically, I don't know.

The heat pump uses the warm outside air, which is more available during the day than in the evening/night. That’s my thought.
