There's no tool better equipped to make boiling water for tea, hot cocoa, and other hot drinks than the classic teakettle. These jug-like vessels are designed to be used with heat, unlike teapots, which are decorative containers that can't come in direct contact with a heat source. Whether you're an avid tea drinker or a casual tea enjoyer, a teakettle is a must-have. Read this guide to learn all about the materials and features that make the best teakettles.

Best Teakettle Types

There are two popular types of teakettles: stove-top and electric. The first type of teakettle relies on an external source (stove top) to heat the water within while the second type of teakettle is self-heating.

Stove-Top

A stove-top teakettle is a basic teakettle designed to be heated on a stove. It typically has a flat bottom and hemispherical body with a spout and handle. Covering the spout is a little cap equipped with a whistle that blows when the water within the kettle begins to boil. Stove-top teakettles are uncomplicated and easy to use. You can also find different types of stove-top teakettles that are specially designed for use on different stove tops.

Electric Stove Tops: Electric stove tops are flat and heat up slower than gas stove tops. If you have an electric stove top, make sure your teakettle is the perfect one for your kitchen by filtering on-site for teakettles made for electric stove tops.

Gas Stove Tops: On a gas stove top, a teakettle might come in direct contact with a flame. Shop for gas-stove-top-compatible teakettles to ensure that yours can take the heat.

Glass Stove Tops: Glass stove tops are gorgeous but can be fragile. Decrease the likelihood your teakettle will damage your glass stove top by shopping for teakettles made for glass stove tops.

Induction Stove Tops: An induction stove top can heat the bottom of your cookware faster than any other stove top, but only if that cookware is made of the right material (for example, steel or cast iron). Shop teakettles designed for use on an induction stove top to make sure that yours is compatible with your high-power stove top.

Electric

Electric teakettles are the next best thing in rapid-water-boiling technology. These self-contained electric devices actually heat themselves without the need for a stove top. They're designed to bring water to a boil in only 2–3 minutes, far faster than conventional teakettles can. Many electric teakettles also have features that improve the safety, versatility, and user-friendliness of the kettle.

Best Teakettle Materials

Stainless Steel: Thanks to its sleek finish and durability, stainless steel is one of the most commonly used materials for teakettles – your kettle will likely survive rough handling and drops without much damage. Stainless steel is easy to clean and is rust- and tarnish-resistant. These kettles can vary in weight, but stainless steel does tend to be a slightly heavier material than others like glass or porcelain.

Cast Iron: Cast iron is the ultimate cookware material because of its heat retention and longevity. Though some bare cast-iron cookware can be susceptible to tarnishing and corrosion, most cast-iron teakettles are enameled to protect them from such damage. But handle with care – the enamel is susceptible to chipping. Cast-iron stove-top teakettles by far are the best teakettles at maintaining their temperature after they are removed from the stove top. Cast-iron teakettles can be heavy and expensive, but if you take good care of yours, it will last you a lifetime.

Aluminum: Light and affordable, aluminum is a great choice for a teakettle if you enjoy the occasional cup of tea. Aluminum tends to be less durable than other metals – it is prone to scratches, dents, and tarnishing. An aluminum teakettle is recommended for the occasional tea drinker rather than the tea aficionado.

Copper: Shaped out of stunning red-brown copper metal, copper teakettles are some of the prettiest kettles available. Copper conducts heat better than stainless steel. This means it will heat up quickly but also lose heat quickly. Copper is a relatively soft metal, so it will require some care to avoid dents and scratches. Your copper teakettle will appreciate the occasional polishing to retain its gorgeous shine.

Glass: Another attractive choice, tempered-glass teakettles are designed to be used in direct contact with a heat source. That said, it's important to be careful not to subject your kettle to drastic temperature changes or rough handling – the glass is still fragile. Easy to clean and simple in design, glass teakettles are excellent for occasional tea drinkers. With just a glance through the transparent glass, you can see exactly how much water is left in your kettle as well as if it's boiling.

Ceramic: Decorative in appearance, ceramic teakettles are made for show and utility. These lightweight teakettles are smooth, easy to clean, and tarnish-resistant. They also won't introduce any odors or flavors into your water as it boils. Ceramic teakettles are great for serving guests – many ceramic teakettles even come with a matching set of teacups. Just be careful not to drop yours – ceramic is prone to chipping and shattering if handled too roughly.

Porcelain: Teakettles in the porcelain category are often metal teakettles that are coated in a durable porcelain enamel. Porcelain enameling protects the metal from rusting and corroding and can often give an otherwise plain kettle some vibrant color. Porcelain is smooth and easy to clean but can chip, which could leave the kettle's metal body susceptible to corrosion.

Plastic: Plastic is an affordable and lightweight synthetic material. Plastic teakettles typically fall under two categories: electric teakettles with almost entirely plastic bodies and stove-top teakettles with bodies that are made of metal or another material with plastic elements. Plastic is a controversial material for cookware because it may leach chemicals, scents, and flavors into your water when it's heated. Modern cookware that incorporates plastic is free of BPA (a chemical linked to health problems), so it's considered safe for use with food and drink.

Best Teakettle Capacities

Capacity is another important metric to consider before buying a teakettle. In this section, we will be referring to the volume of a U.S. cup (8 fl. oz.) and the volume of a standard cup of tea (5 fl. oz.).

Under 1 qt.: Small teakettles can hold less than 1 qt. (or 4 U.S. cups) of water. A teakettle of this size holds enough water to serve four to six people (or two to three if you'd like double the drinks). Teakettles under 1 qt. are easier to store and lighter than larger options, which makes them great for the occasional tea drinker.

1–2 qt.: Two quarts equates to 4–8 U.S. cups of water or six to 12 standard cups of tea. Teakettles of this size are fairly standard and can accommodate most of your daily hot or boiling water needs.

2–3 qt.: 2–3 qt. teakettles can hold 8–12 U.S. cups or 12–18 standard cups of tea. These kettles (especially electric models with keep-warm settings) can supply your entire household with hot water all day long. If you're an avid chef, you know it can be easier to heat water for recipes using a kettle rather than a stove-top pot. Kettles of this size are great for larger recipes that call for hot or boiling water.

Over 3 qt.: Most kettles that hold over 3 qt. of water are electric – all you need to do to use one is fill it up and turn it on. These teakettles can serve many people without needing to be refilled, which makes them great for serving large groups. Most of these large devices also have spigots that allow the user to dispense water without tipping the kettle, a must-have feature for a heavier device.

Best Teakettle Features

Whistle: Steam-activated teakettle whistles alert you that your water is boiling. A whistle is a great feature to have on a stove-top teakettle, especially if you like to leave your water to boil while you do other things around the house. The shrill sound of one of these whistles is hard to ignore!

Heatproof Handle: Ensure that you can handle your teakettle safely without an oven mitt by opting for a model with a heatproof handle.

Automatic Shutoff: Automatic shutoff is an essential feature of many electric teakettles that stops the heating process once the water reaches its boiling point. There's no need to stick around and watch one of these kettles – you can even leave the house while it is working without having to worry about burning your house down. An automatic shutoff feature is even more convenient if it comes alongside a keep-warm setting – the keep-warm function will keep your water at the right temperature even after the heat has shut off.

Rapid Boil: Another feature unique to electric kettles is rapid boil – electric kettles are able to bring water to a boil in only a couple of minutes.

Water-Level Indicator: Water-level indicators are transparent windows, gauges, or digital readings that show you exactly how much water is left inside the kettle. This feature is common on larger teakettles.

Variable Temperature Control: Some high-tech electric teakettles provide you with more than one temperature setting, allowing you to heat water to more precise temperatures.

Limescale Filter: Limescale, a buildup of minerals present in most tap water, can damage your teakettle – especially if it's electric. A limescale filter can help filter out these pesky minerals and prevent limescale buildup.
