What Makes a Washing Machine Energy Efficient
Washing machines are a must-have in any home. From keeping our clothes fresh to saving time, a good washer is an essential part of our everyday lives. But in 2025, it's not just about getting clothes clean anymore. With the rising cost of power and growing environmental concerns, more Kiwis are looking for washing machines that do the job efficiently without wasting water or energy.
But what features make a washing machine energy efficient? If you're shopping for a smarter home appliance, this blog will help you understand the key features, technologies, and tips that can save you money and make a world of difference.
What is Considered an Energy-Efficient Washing Machine in NZ?
Energy efficiency isn’t just a buzzword. An energy-efficient washing machine means a washer that uses less power and water to complete a wash cycle, without compromising performance. It is designed to be smarter about how it runs. It adjusts water levels, optimises spin speeds, and even senses the size of your load.
These smart features lead to lower electricity bills and a reduced carbon footprint over time. This is particularly useful for households that do multiple loads per week.
Features That Make a Washing Machine Energy-Efficient
Below are the characteristics you need to look out for when buying a washing machine.
1. High-Efficiency (HE) Design
You’ve probably seen this term as "HE" when browsing washing machines. High-efficiency models use less water and have faster spin cycles to remove more moisture, which means less time (and energy) needed for drying. HE washers don’t have central agitators like older machines. Instead, they use a tumbling or impeller motion to clean clothes gently and effectively. Interesting, right?
2. Front-Loading vs. Top-Loading
Front-load washing machines are generally more energy-efficient than traditional top-loaders. They use gravity to tumble clothes through water, which requires less of it. While top-loaders have improved significantly, front-loaders still come out ahead in most efficiency comparisons. You can get the best Midea front-load washing machines here at Appliance World, too!
3. Advanced Wash Systems
Modern machines use sensors and algorithms to customise wash cycles to your load. This means they don’t use more water or energy than needed. Some models even have multiple wash motions to efficiently clean different fabric types while caring for the fabric.
4. Efficient Water Usage
Water and energy often go hand in hand. Less water means less energy to heat it. Energy-efficient washing machines are designed to use the minimum amount of water needed to get the job done. This makes a huge difference, especially if you're on metered water.
5. High Spin Speeds
A faster spin cycle removes more water from your clothes at the end of a wash. That means shorter drying times. This is especially helpful if you're using a dryer. Look for washers with variable spin speed settings, so you can adjust them based on your load.
6. Load Sensing Technology
There are also cheap washing machines that can detect the size of your laundry load and adjust the water level, detergent amount, and cycle length accordingly. This prevents waste and ensures you’re only using what you need.
Energy Efficiency Ratings and Certifications
ENERGY STAR Certification
One of the easiest ways to spot an energy-saving washing machine is by looking for the ENERGY STAR label. This certification is awarded to appliances that meet strict energy efficiency standards set by international programmes. ENERGY STAR-rated laundry machines typically use 25% less energy and 33% less water than standard models.
Energy Labels in NZ
Here in New Zealand, appliances come with Energy Rating Labels. These show you how energy-efficient a model is compared to others of the same type in just one glance. More stars = more savings. You’ll also see an estimated yearly running cost, which is great for budgeting.
Technological Innovations That Improve Energy Efficiency
With the rise of advanced technology, there have been so many upgrades that make today’s washing machines more energy-efficient and more sustainable. Here are some of those innovative features that renowned brands like Midea use to showcase their appliances.
Inverter Motors
Inverter motors are designed to operate at variable speeds. Unlike traditional motors that run only at full power, inverter motors adjust their speed to match the load, reducing energy usage. They’re also quieter, more durable, and gentler on clothes.
Eco Modes and Cold Wash Options
Many modern washing machines come with eco-friendly cycle options. Cold wash settings are particularly energy-saving, since most of the energy used in a wash cycle goes into heating water. With today’s detergents and machine technology, cold washes still get clothes clean.
Smart Features and Connectivity
WiFi-enabled washers let you monitor and control your machine remotely. More importantly, they give you usage insights and suggest more efficient washing habits. Some even send alerts when it's time to run a drum clean cycle or recommend when to use eco modes.
Here’s How You Can Maximise Energy Efficiency at Home
Even the best washing machine needs the right habits to deliver its best performance. Here are a few simple things you can do:
Wash Full Loads
Avoid half-loads whenever possible. Running full loads uses energy and water more efficiently.
Use the Right Detergent
High-efficiency machines need HE-labelled detergent. These produce fewer suds, which helps the machine rinse better with less water.
Stick to Lower Temperature Cycles
Most of the energy in a wash cycle goes into heating water. Unless you need a hot wash for hygiene, cold or warm settings will usually do the trick.
hoose the Right Cycle
Choose the wash cycle based on your load. Quick washes can be efficient for lightly soiled clothes, while eco settings are ideal for general laundry.
Maintain Your Machine
Clean filters, detergent drawers, and the drum regularly. A well-maintained washer runs more efficiently and lasts longer. Try replacing worn-out appliance parts immediately, like a faulty hose or door, to prevent bigger issues down the line.
