Hallo! I just arrived in Germany. I’m still learning and figuring out on when to open and close the windows. Pardon me because I came from a tropical country. I have learned about stoßlüften and ankippen and also tried both modes. Right now the temp is around ~20 at afternoon and -12 at night. Should I do stoßlüften for 10 minutes a few times a day, or just do ankippen on longer periods?
Also is it okay to do ankippen while keeping the curtains closed? Danke schön!
