Freezers are one of the few appliances that are on all the time, so it’s important to get an energy efficient model. This makes a difference to your utility bills and reduces your impact on the environment – it’s a win-win!
But which models are the most efficient, and which cost a little more to run? Scroll down to find out.
The Energy Efficiency Rating
The simplest way of narrowing down products for efficiency is to use the energy label.
Thanks to EU regulations, every freezer has to have one of these displayed, so you can quickly tell what grade the appliance is.
The scale goes from A+++ for the most efficient appliances, down to G for the least efficient. The rating is calculated based on energy consumption in relation to internal volume.
If you have a very old freezer, from before 1999, it could have a rating anywhere between A and G, so investing in a newer model is probably a good idea.
Beyond the Rating
Of course, there are other aspects to take into account regarding energy efficiency that go beyond the letter rating.
For instance, two different sized freezers with A++ ratings could have very different running costs – a bigger appliance will normally require more energy. Buying the right size appliance to suit your demands will help improve your energy costs.
Old vs. New
If you have an old freezer and are think of upgrading, new models will likely be much more efficient.
Since mid-2012, manufacturers only produce freezers that are rated A+ to A+++. This means you can be assured your new freezer will have a good efficiency rating, and it’s likely these newer models will be more efficient than older models.
Which? have done a lot of research into the running costs of various domestic appliances.
According to their data, a new freezer can cost anywhere between £20 and £67 annually. However, if you have an older appliance, it may cost even more to run than the upper estimate.
If you purchased the most efficient freezer over one of the least efficient, you could save hundreds of pounds over its lifespan.
Helping your Freezer
There are a few measures you can take to help get the best efficiency out of your freezer.
It might seem obvious, but putting anything hot or warm in the freezer should be avoided. It can raise the internal temperature, affecting the frozen contents, and makes the freezer work harder.
Make sure that occasions which require the door to be open are kept to a minimum. An open door means cold air escapes and warm air gets in. If you’re prone to leaving the door open, consider buying a model with an acoustic alarm that will remind you to close it.
Keeping your freezer fuller means there is less empty space that is needlessly being cooled. Stock up on spares or a naughty tub of ice-cream – it’s all for the good of your freezer of course.
Frost and ice in the freezer also lower efficiency. If you’re not a fan of defrosting manually, consider a frost-free model.
