12 Best Energy Efficient Kettles UK | Buyer’s Guide & Reviews | 2020

Energy Efficient Kettles

An energy efficient kettle is an essential appliance no household can be without. A decent kettle is a must for warming up water for piping hot cups of tea and pots of coffee. However, this humble appliance is often called for when it comes to boiling water for cooking, preparing formulas for nursing infants, filling water bottles and much more.

In the past, electric kettles were unreliable, taking an age to boil with little in the way of safety features provided. However, the best electric kettle models available today provide you with extensive features and functions, making everyday life a little simpler.

Our detailed guide includes everything you need for selecting the best kettle for your needs. Whether you are looking for a smart kettle that can be controlled remotely or an energy efficient kettle that is kinder to the environment, our in-depth guide will steer you in the right direction.

Key Things to Consider When Buying an Energy Efficient Kettle

There is plenty to think about when looking for an eco-friendly kettle. While it can be tempting to go for a stylish design, take some time to explore the functionality of any appliance that catches your eye.

You want a kettle that will boil quickly, but consume minimal energy. A quiet kettle is also worth thinking about. Quieter appliances are not just less distracting, they tend to be more energy efficient and friendly to the environment. Beyond this, there are more critical features to think seriously about.

Rapid Boil Functionality

If you use your kettle regularly throughout the day, a quick boil function is a must. Quick boil functionality is usually only effective if you are boiling smaller amounts of water. Most kettles offering a rapid boil function will only usually do so for a single cup of water.

The best kettles offering rapid boil functionality will provide you with the desired temperatures within a minute. This is a feature that will come in handy if you are forever running late in the mornings, but do not want to start the day without your caffeine kick.

Keep Warm Feature

If possible, look for an energy efficient kettle that provides you with a keep warm function. This functionality will mean that, once boiled, the kettle will ensure the water retains its high temperature for as long as possible.

More affordable appliances will provide you with a keep warm function that lasts for around half an hour, although you will find plenty of kettles that will keep water warm for hours at a time. A keep warm feature is incredibly convenient, but is also eco-friendly as you will avoid having to reboil the kettle should you get distracted.

Variable Temperature Settings

The most expensive kettles will usually include variable temperature control. These types of kettles will include onboard controls that allow you to set a desired temperature. Once the kettle has brought water up to this temperature, it will shut off. Kettles that feature variable temperature control will usually include three or four distinct temperature levels to choose from.

You will obviously have standard boiling temperatures available, but you can also find lows of around 60 degrees Celsius as well. Such temperature controls are very useful for those who prefer their tea or coffee a little cooler to taste. It also means you do not have to wait around for your drinks to cool if you are in a rush.

Boil Dry Protection & Safety Features

To ensure your kettle lasts for as long as possible, safety features are crucial. Auto shut-off features are therefore essential. An auto shut-off feature will mean water does not continue to churn around in the jug once it has reached boiling point, preventing hot water from splashing upward and out of the kettle itself.

Boil dry protection is also essential. When in a hurry, it is all too easy to turn a kettle on without remembering to fill it first. This can damage the heating element and internal components of a kettle. However, boil dry protection will prevent this from happening, shutting of the appliance before it completes a boiling cycle.
