I have been thinking that to help me keep my seed potatoes from sprouting over winter, a fridge might offer a good solution. So, finding myself at a loose end in a supermarket recently, I was wandering around looking at the fridges.
I was intrigued the other day by a poor energy rating (F) given to a highly efficient light bulb (an LED), so I paid attention to the energy labels on the fridges. I saw two apparently equal-sized fridges, one rated F, the other rated E. According to the label, the E one consumed 141 KWh per year, that is more than the F one that consumed only 112. They both appeared to be the same size. What is going on?
Aha! The E one has a freezer compartment inside at the top, the F one does not. The fridge compartment is therefore a bit smaller than the F one. So, apparently, fridges with a freezer bit are assessed differently: they are allowed to consume more electricity and still get a better rating. Not comparing like with like.
Wandering on, I found a tall fridge with no freezer compartment but a bigger capacity (263 litres instead of 127 litres - twice as much as the F one above. It consumes 133KWh per year vs 112, that is 18% more. Energy rating also F.
So a fridge with twice the capacity for only 18% more electricity consumption doesn't appear to be more efficient? On marche sur la tête.
