Tips for a more efficient freezer:
- Set the your freezer temperature at -18°C
- Freeze plastic containers full of water if the freezer isn't full
- If you have a manual or semi-automatic defrost, regularly defrost your freezer. The buildup of ice on the coils inside the unit means that the compressor has to run longer to maintain cold temperatures, wasting energy. Assuming that removing ice build up on the coils on average saves 10% of a refrigerator's energy, this amounts to up to 60 kWh/yr.
