Mine is ~8 years old Samsung with i don't know which energy efficiency class: 1,1-1,3kWh/24h Vertical freezer with some 7 chests which is many more years older takes 0,6-1kWh/24h - probably depends when we open it and when not. Probably better to look at monthly (October) stats: 38,64kWh Fridge, 21,81kWh for freezer. Hmm, August 40/35; July 27/24. Dunno why it fluctuates so much. Ofcourse, October was heating season, but that doesn't seem to impact freezer for worse. Which is weird - it is 2 meters apart from heat source. But yeah, summer could hahve
