• Automatic Shut-off: Automatic shut off is a key function of water kettles. Once the water reaches the boiling point, it either turns off by itself or activates an alarm signal to warn it is boiling. This helps prevent issues like burnt food, gas leakage, and pan corrosion in traditional stovetop kettles. In electric models, the shut-off function helps prevent overheating and eventually burning the kettle.
• Boil Dry Protection: Boil dry protection is a critical function in electric kettles. If the water level is too low or empty, the protection feature either shuts it off or prevents it from heating. This mitigates the risks of damaging the kettle by overheating or burning.
• Spout with Lid: Water kettle spouts have lids that provide safety when pouring out hot water. They allow safe steam release and prevent hot water from splashing and burning the user. Kettles with removable lid spouts are easy to clean.
• Heating Capacity: Heating capacity varies with different kettle models. From a few cups to several liters of water, electric kettles come in various sizes. The capacity determines the number of cups or liters the kettle can brew within a single session.
• Material: The materials used in constructing water kettles affect their durability and insulation properties. Metal kettles like stainless steel and cast iron are durable and excellent at retaining heat. However, they need more care to prevent rusting. Glass kettles offer better visibility, while plastic ones are lightweight and economical.

How to choose water kettle

Water kettles, whether electric or stovetop, come in various materials. They may include stainless steel, glass, copper, and cast iron. Each material has unique benefits and drawbacks. For instance, stainless steel tea kettles are durable and easy to maintain. They won't stain or retain odors. On the flip side, they have low thermal conductivity. Therefore, users may need to wait longer for the water to boil. Glass kettles are beautiful to look at. They're also more durable than kettles made from other materials. Users can see the water boiling clearly. Unfortunately, glass is fragile. It can shatter into pieces upon great impact or under extreme temperatures. Some manufacturers use copper to make water kettles for added beauty. Copper has excellent thermal conductivity properties. It boils water faster and saves energy. The only downside is that copper kettles tend to tarnish over time. They also require a lot of maintenance to stay in good condition.

A cast iron kettle with an enamel coating is one of the most long-lasting options available. In contrast to other materials, it retains heat for a long time. This enables the water to stay hot even after the heat source is removed. The downside is that kettles made from cast iron with an enamel coating are heavy and prone to crack when dropped.

Consider the capacity of a kettle before buying it. Electric kettles come in various capacities ranging from 1 to 2 liters or more. A 1.7-liter electric kettle is ideal for a family of four. A 1.8-liter kettle can prepare enough water for people who have company or work in large offices. Small kettles with one-liter capacity are perfect for compact homes with one or two occupants.

Water takes longer to boil in larger kettles than in smaller ones. Regardless of size, they all use about the same amount of energy. However, keep in mind that larger kettles use more power. This means users need to pay higher electricity bills.
