One To Avoid

Tower T10052BLK Empire 1.7 Litre Kettle with Rapid Boil

Why we don't recommend it: Durability and maintenance issues make this kettle poor value despite attractive design

We tested the Tower T10052BLK Empire kettle, and while it offers rapid boiling technology (perfect for busy mornings) and a stylish Art Deco design, the drawbacks quickly overshadow the benefits.

Key Concerns

• Lightweight plastic build feels flimsy and lacks durability despite premium appearance – materials deteriorate over time
• Unusually loud operation during boiling disrupts quiet kitchen environments – noise level significantly exceeds acceptable standards
• Removable filter proves ineffective at preventing limescale buildup in hard water areas – requires frequent intensive cleaning unwarranted for this price point
• Poor practical durability contradicts initial Art Deco aesthetic appeal – not justified given price and long-term maintenance burden

The lightweight plastic build doesn't live up to its premium appearance. Over time, the materials feel flimsy and less durable, which diminishes its initial charm. The noise level during operation is unusually loud (enough to disrupt a quiet kitchen), making it unsuitable for those who value peace.

For users in hard water areas, maintenance is particularly frustrating. The removable filter does little to prevent limescale buildup, requiring frequent cleaning to maintain water quality. This level of upkeep is unexpected for a kettle in this price range.

While it's efficient at boiling water and visually appealing at first glance, the practical issues make it hard to recommend. For anyone prioritising durability, quiet performance, or ease of maintenance, this kettle falls short. Overall, it doesn't justify its cost and is a product we would advise against.

How We Evaluated and Chose the Best Energy-Saving Kettles

When testing energy-saving kettles, we didn't just stop at boiling water. We took a comprehensive approach to uncover what makes a kettle energy-efficient, user-friendly, and reliable. From performance metrics to everyday usability, every detail was considered. Here's how we did it:

Efficiency and Energy Usage

We measured how much energy each kettle consumed and how quickly it boiled water. Using a wattmeter, we recorded electricity usage for various volumes, ranging from a single cup to full capacity. Boiling times were timed and compared to assess efficiency and energy savings.

Models that boiled water quickly while consuming less power scored higher in this category.

Boiling Speed

To evaluate speed, we timed how long it took each kettle to boil different amounts of water—250ml, 500ml, and 1 litre. We also tested for consistency across multiple boils to ensure performance didn't degrade over time.

Speed is essential, especially for busy mornings, and our testing focused on kettles that delivered on this front.

Temperature Control Accuracy

For kettles with temperature settings, we used a thermometer to verify if they achieved precise temperatures, such as 80°C for green tea or 90°C for coffee. We also tested their ability to maintain the desired temperature for up to 30 minutes using "keep warm" features.

Accurate temperature control enhances versatility, making it easier to prepare a variety of drinks.

Noise Levels

We assessed noise levels during boiling using a decibel meter. Louder kettles or those with disruptive beeping noises were noted, as they could detract from the kitchen experience. Quiet operation is especially important for households that value peace during early mornings or late evenings.

Build Quality and Design

We closely examined the durability and aesthetics of each kettle. Materials like stainless steel and BPA-free plastic were evaluated for robustness and safety. Comfort and ergonomics, including the handle and spout, were tested for ease of use.

We also considered the kettle's visual appeal and how well it complemented modern kitchen setups. A kettle that's both stylish and sturdy adds value to any kitchen.

User-Friendliness

Ease of use plays a critical role in day-to-day convenience. Water level indicators were checked for visibility, and we evaluated how simple it was to fill, pour, and clean. Filters were tested to see how well they managed limescale and debris.

Kettles that were intuitive to use and maintain scored higher in this category.

Safety Features

Safety is a priority for any kitchen appliance. We ensured that each kettle had auto shut-off functionality to prevent overheating and boil-dry protection to avoid damage when used without water.

Additionally, we checked how stable the kettle was during operation and whether its exterior became excessively hot to the touch, minimising burn risks.

Extra Features

Advanced features like temperature preset, digital displays and keep-warm functions were tested for reliability and practicality. Cord storage and compact designs were evaluated for ease of use in smaller kitchens. Models with innovative features that enhanced convenience and performance stood out.

Value for Money

We compared each kettle's features and performance to its price point. Models with robust performance, advanced features, and durable construction offered the best value. Warranties or guarantees added extra points, as they provide long-term peace of mind for buyers.

Real-World Use

To simulate daily use, we tested each kettle over a week, boiling water for tea, coffee, and cooking. We noted any recurring issues, such as limescale buildup, noise, or uneven performance.

This helped us assess reliability and user satisfaction over extended periods, ensuring the kettle would perform well in real-world scenarios.

Frequently Asked Questions

Is an Electric or Stovetop Kettle More Efficient?

An electric kettle is generally more efficient than a stovetop kettle because it directly heats the water using electricity, minimising energy loss. Stovetop kettles often waste heat as it disperses around the pot and burner. Electric kettles with rapid boil features are specially designed to save energy and time.

Is It Cheaper to Use an Electric Kettle or Gas?

Whether an electric kettle or gas is cheaper depends on your local energy rates. In many cases, electric kettles are more cost-efficient because they heat water faster and waste less energy. However, a gas stove might be the more economical option in regions where gas is significantly cheaper than electricity.

Does Boiling a Full Kettle Use More Electricity?

Boiling a full kettle does use more electricity because it requires heating a larger volume of water. To save energy, boil only the amount of water you need. Overfilling the kettle leads to unnecessary energy consumption and longer boiling times, making it less efficient overall.

Which Is Best Stainless Steel Kettle or Plastic Kettle?

A stainless steel kettle is generally better than a plastic kettle due to its durability, safety, and resistance to heat-related wear. Stainless steel also avoids the potential leaching of chemicals into the water, which can sometimes occur with plastic models.

Additionally, it often retains heat better, making it more energy-efficient.

Is There a Way to Make a Kettle More Energy Efficient?

You can make a kettle more energy-efficient by boiling only the amount of water you need, descaling it regularly to maintain heating efficiency, and choosing a kettle with rapid boil technology. Additionally, using a kettle with good insulation can help retain heat, reducing the need for reboiling.
