How are washing machines energy efficient? Which to buy?

Finding the most energy efficient Washing Machine model for you is no easy task, especially since the changes to the UK energy efficiency rating scale, which took place in 2021. However, when investing in a washing machine it’s fundamental that you select the perfect product for you, that has the capabilities to bring you as many energy saving avenues as possible. 

LG offer a great range of energy efficient Washing Machines, with a variety of models that cater for your household’s requirements. At LG, we are committed to developing innovations that ensure our products are as energy efficient as possible using our array of smart technologies. 

This article offers a step-by-step guide to support you in selecting the best energy efficient Washing Machine for your household’s needs.  

In 2021, the UK modified its energy efficiency rating system for household appliances, meaning new energy ratings for washing machines were now put into place. The system used to go from A+++ to D, but today it runs from A to G. As a result, an old A+++ Washing Machine will now get a new rating in the upgraded system. It's also worth noting that an appliance's current energy rating may not be exactly comparable to its prior energy rating, as the criteria for categorizing appliances has changed dramatically.

The new adjusted rating system has been revised to help both consumers and professional buyers to better understand a product’s overall energy efficiency, considering more factors than ever before. At the moment we are seeing a climate where reducing energy usage is vital, as consumers are looking for new ways to save energy and money. Manufacturers and brands seen this demand and as a result have been developing products that use significantly less energy causing the old system to become obsolete, having been developed over 25 years ago.

So, what is good energy rating for a washing machine? Thankfully, the new system improves clarity and offers consumers the average energy consumption in a familiar looking colourful scale from A-G, with some new additions including a QR code on the top of the labels, available to scan for more in-depth product information. Most products that were previously classified as A+++ will now be classified as a B or C energy efficient model, however that’s not to say there are new models that don’t make that A-rating such as the LG WiFi connected F6V909BTSA. 

Essentially, if you are wondering what the difference is between an A and B energy rating washing machine, a simple rule of thumb to remember is that it’s typically more efficient at the top, and “less efficient” at the bottom, so an A-rated machine should typically be better than a B model. However, with few products reaching the A status, a B model will provide everything your household needs and often much more.

The Energy Savings Trust, have produced a series of guides for those users who are looking to gain a deeper understanding into how the new energy rating system works so they feel more confident when entering the buying process. 

There are several factors that affect your washing machine’s energy efficiency, from factors relating to your model, to the way you use it. We have compiled some of the most significant factors to be aware of, so even if your model doesn’t have the highest energy rating you can be aware of which factors can help you save on energy the most. 

The most important factor, as advised by the Energy Saving Trust, is making sure you don’t overload the washing machine drum. In overloading the drum, you can damage the washing machine’s structure and as a result make the machine less efficient. Furthermore, in overloading your washing machine you limit the circulation of water and detergent to your laundry as the clothes are unable to move around- resulting in clothes coming out unclean and an increased likelihood of items needing a second wash. 

We’ve included a list of other factors that can impact your machine’s energy efficiency:  

• The temperature you wash your laundry at 
• The cycle and load capacity of your machine 
• The amount and type of detergent you are using in your machine 
• The age of the model. In recent years, there has been rapid improvement in the energy efficiency of washing as a result of new Ecodesign legislation, which also limits the amount of energy that washing       machines consume on standby which is frequently overlooked when thinking about your ideal washing machine purchase 

There are several simple tips that can be adopted to make sure you are maximising your machine’s energy saving potential. Our experts at LG continue to develop new technologies and performance measures to continuously increase the benefits of energy-saving, however so much is determined by how you use your machine at home. So, when doing your laundry in future consider the recommendations below: 

Washing machines are most energy efficient when performing at lower temperatures for longer durations

• The temperature you choose to wash your clothes at also has an impact on your energy usage, if you choose to wash at 20°C or lower you can minimise the amount of energy your washing machine consumes 

Make sure you follow manufacturer recommendations when loading the washing machine and selecting your preferred cycle 

Overdosing with detergent can also affect your washing machine’s energy efficiency. Detergent overdosing results in increased work for the machine, decreased wash performance and also hinders your overall savings as it can result in clothing damage and the need for replacement items. 

Autodosing washing machines will correctly dose the needed amount of detergent, helping to reduce the risk of the issues mentioned above 

• Making sure you are being economic with your washing can also save energy as washing a load at the full rated capacity will save more energy than running two cycles with half the load
• Turn your washing machine off when you are not using it, so it is not wasting energy on standby 

As we mentioned above, the biggest way to save energy with your washing machine is to make sure you have one of the newest models that has the benefits of the new Ecodesign legislation. At LG, we have gone above and beyond to make sure that our washing machines are providing you with the most energy efficient benefits. 

When selecting your energy efficient washing machine, it’s important that you have a clear idea of your own personal criteria for a good energy saving appliance. It’s important to factor in things like the size of your household, so you can get a washing machine with the right capacity for you. It’s also key to think about whether you should invest in a smart washing machine and technologies you need - whether you want an appliance that connects to your smartphone or one that autodoses your detergent.
