New freezer: minus 440 kWh per year on power consumption

Yesterday our old and broken freezer was replaced by a new A++ class freezer, a Liebherr GP1466-22.

While hunting down the large power consumers in our house, i found out that our old freezer had a defective thermostat. It was constantly freezing, 24 hours a day! Something had to be done about that, since constantly cosuming 65-70W is way to much! Now that the new freezer has been working for 30 hours or so, i can see it has an average power usage of 16.5W. That’s 145 kWh per year, where the old freezer used 587 kWh. That’s another 440 kWh saved on a yearly basis…

Now i wonder how the manufacturer has come to the advertised 135 kWh…
