No obvious bad points.
Overall score includes:
Temperature performance (55%): We check how well the freezer maintains even temperatures. We also check how it copes with ambient temperature change – and whether the freezer allows a good range of temperature choices and the controls’ mid setting gives an appropriate temperature.
Insulation efficiency (30%): This relates directly to the amount of insulation the freezer has and indicates how long it would take to warm up in a power cut. First, the freezers are switched off in a room with an ambient temperature of 32°C. The test starts when the freezer temperature is -15°C and ends when it gets to -5°C. The longer this takes the better.
Cool-down (15%): We measure how long it takes to cool the air in an empty freezer, from when it’s switched on until it reaches -13°C in a warm temperature-controlled room.
What about energy use?
We assess energy usage based on the manufacturer’s claimed energy usage as well as measured energy usage. A pass means the measured energy usage was no more than 7.5% higher than claimed, anything over that is a fail. Once a freezer fails, we stop measuring. In previous tests, we would have kept testing to find a maximum energy usage reading.
Claimed energy use is the amount of energy (in kW/h) the manufacturer says its fridge uses. If a fridge uses more power than claimed, it’s not necessarily bad, just not as efficient as claimed.
