how many kwh does a fridge use nz
At 15 kWh, trading in a pre-1986 fridge for a new efficient one would save about $158 a year in electricity costs. And some older fridges are even worse than the average. One reader estimates her savings to be $238 per year for trading in her 1979 fridge for a 2004 model.ridge should be 36-40F, and the freezer should be 0-5F (-17 to -10C). Fridges set 10 degrees lower than needed (or freezers set 5 degrees lower than needed) can increase energy use by as much as 20-25%. Personally, I set my own fridge to 56 because as a vegan I never store super-perishables like meat or dairy.
