1. Design and Types

Understand the two main types of kettles - jug and dome. Jug kettles are taller with side handles, while dome-shaped kettles resemble traditional stovetop models. Electric dome kettles often have lift-off lids and smaller water capacities

2. Speed and Wattage

• Consider the power element, usually measured in kilowatts (kW), for fast boiling. A power element of 3kW is often considered optimal for quick boiling, and the article suggests that all top-scoring kettles have this wattage.

3. Capacity and Usage

• Be mindful of the capacity of the kettle, typically ranging from 1.5 to 1.7 liters. Understand the importance of knowing the minimum capacity for smaller quantities, especially if you often boil water for just one cup.

4. Features to Consider

• Explore key features like a visible water level indicator, variable temperature settings for brewing different types of tea and coffee, and smart features like app connectivity. Consider the weight of the kettle, the grip and shape of the handle, and the presence of filters for hard water areas.

5. Safety and Energy Efficiency

• Learn about safety features, such as boil dry protection, which automatically switches off the kettle if there's not enough water. Consider the external casing's temperature, especially for households with children. Look for energy-efficient options, including quick boil or one-cup settings, and auto shut-off features to prevent wasted electricity.
