It's freezing cold here again, so the heating is still running hard...Where is it so "freezing cold" right now?
Are you in some kind of cold spot?

Are you in some kind of cold spot?? At night 0°C (32°F) and during the day below 10°C (50°F). No idea what's going on here, I only read 20°C (68°F) every day in the weather report 😀
Here’s an update from me again 🙂
Over the past 10 days, we have averaged a heat output of 80 kWh and an electricity consumption of 19 kWh per day. This means the heat pump is operating with a coefficient of performance of about 1:4, which seems pretty good.
To reduce the heat output even further, I lowered the heating curve by 2 degrees. Currently, due to the sun, we have the issue of needing to ventilate a lot during the day to avoid overheating (with outside temperatures around 30°C (86°F), the windows are almost always open), while at night, when it drops to 0°C (32°F), the heating runs again.
I hope the lower heating curve will help balance this effect since the sun warms the rooms sufficiently in the morning.
We’ll see if it works and saves electricity 🙂
