Every year again :D right? So here it’s actually constantly 12 degrees. I am very surprised that my heating is still asleep and it’s still 21 degrees inside.
But I think it will start soon if it doesn’t get warmer.
I checked in the summer now how much the heating needs. About 3 kWh daily for standby and hot water. Whether that is good or not I don’t know, but that’s also 90 kWh per month and thus about 25 euros.
