I’m not trying to sell you a fridge. We’re not that type of wesbite!
Do you wonder what the difference between an A+ Fridge, and an A+++ Fridge is? I’ve never been awarded an A+++ in anything, so what has this fridge done to deserve it?!
Want to know which fridges and freezers will save you the most money?
The Energy Community are here to help. In this knowhow, we’ll give you the facts about fridge ratings.
How are fridge ratings calculated?
First, the Energy Efficiency Index (EEI) is calculated by dividing the fridge’s annual energy consumption by a standard value.
There is a potentially excessive equation to calculate this “standard” value which takes into account type of fridge/freezer (e.g. chest freezer, larder fridge, upright fridge etc), volume, design temperature and added features such as a chill compartment, or if it is built in to your kitchen. You can see the equation in this paper: EU Commission Directive 2003/66/EC.
The result is multiplied by 100 to get a percentage, and then the rating is assigned based on this value as follows:
Energy Efficiency Index
between 22 and 30
|between 30 and 42||
So what does this mean?
- It means that different types of fridge will be judged upon different standards, so an A+++ “built in” fridge is not necessarily more efficient than an A++ freestanding fridge with similar dimensions.
- The ratings do not account for accessories on your fridge that you may not need (such as a fridge with a freezer compartment, when you already have a freezer)
- One A++ rated fridge could be cheaper to run than an A+++ fridge, if the A+++ fridge has added features.
What should you look for?
From a completely impartial viewpoint, to get the most efficient and cost effective fridge you should:
- Choose the right fridge based upon your needs. Don’t get a huge one if you’re not going to use it, and consider whether you need that “super chilled” zone.
- Take a look at the KWh rating (smaller the better, check out this knowhow to know what a KWh is)
- Buy the fridge with the highest rating and lowest KWh that you can afford.
Everything summed up in one line
Adding an extra + will never cancel out buying a fridge twice the size that you need!
