My fridge is from Haier and is rated A+++ (2017), with about 200 litres volume, half of which for the freezer.

The reference energy consumption is 178 kWh/year, but in a week of October I measured the energy consumption and I obtained an estimate of 230 kWh/year.

The device is most of the time almost full, but that has likely a low impact. More important, we are two people so the amount of food getting in and out per week is likely less than what the manufacturer expects, given the size of the fridge, suitable surely for three or four people.

Is the measured discrepancy reasonable? Or should I complain?
