We have 2 refrigerators, one that is the official fridge in the kitchen and the other one is the backup in the terrace. They are both medium in size. When the fridge in kitchen couldn’t handle the load, we turn on the one in the terrace. Friends have advised us to buy a bigger fridge but come to think of it, why the need for a big one when we have 2 already? In terms of electric consumption, it’s obvious that our 2 refrigerators are economical than one big fridge.
