How to choose your kettle with adjustable temperature

If the adjustable temperature kettle seems simple and very convenient to use, it is not easy to choose the one that suits our needs and expectations.

#1 - The energy output

This is an essential element when buying an electric kettle. Expressed in watts, the power of the adjustable temperature kettle will determine the speed at which the water is heated.

It should be noted that the slower the appliance works, the more energy it uses. In fact, an appliance that uses a lot of watts will necessarily boil faster. Certainly, a kettle with a power of 1500 W is more economical than a model of 2400 W.

For a fast and efficient heating speed, it is preferable to choose a kettle with a power of about 2000W and more. It should be noted that there are models that boil water in less than a minute.

#2 - The temperature variation levels

Indicated to the category of the kettle, the different temperature levels are the essential elements. This is the whole point of this device to be able to adapt the heating level according to its needs or to the preparation of the type of hot drink.

Predefined by the manufacturers, the selectable temperatures will vary over a range from 40° to 100°C. At this level, the latter will be subdivided into 3, 5 or 7 heating temperature levels depending on the specifications of each model.

For example on 5 temperature steps, the kettle will offer heating temperatures of 60°, 70°, 80°, 90° and 100°C.

#3 - The capacity

The capacity or capacity of an adjustable temperature kettle must be adapted to your needs. That is, depending on the use, it is important that the kettle can have a good capacity of water capacity. The majority of adjustable temperature kettles have an average capacity of 1.5 to 2 liters.

Note that it is also essential to consider the capacity of your kettle in relation to the size of your household. For example, a kettle with a capacity of 1.7 liters will be perfect for a family of 4 people.

#4 - The kettle's material and coating

The manufacturing materials and coatings are also very important criteria when buying a quality adjustable temperature kettle. On the market, the majority of kettles are made of stainless steel, glass or plastic.

Plastic is the cheapest, but very difficult to maintain and tends to discolour, sometimes with white marks. In this regard, the glass kettle is quite excellent, but considered mainly by many users as a little fragile.

But you should know that this is not always true because the glass construction of kettles is specially designed to resist heat. For more guarantees on its robustness, a stainless steel adjustable temperature kettle may be the best solution. But the choice will depend on your preferences and budget.

#5 - The additional features and safety features

At this level, it will be necessary to consider the availability of the keep warm system, the control panel, the boiling warning or the water level indicator and the anti-scale filter, etc. And most importantly, since it is a powerful household appliance, it is mainly advisable to question the safety system of the kettle.

In general, a kettle with adjustable temperature incorporates an automatic shut-off function when the preset temperature is reached. For even more safety, choose a kettle that has a stop function when the kettle is empty or when the quantity is exceeded.

How to use an adjustable temperature kettle?

The adjustable temperature kettle is an easy to use household appliance. However, a few precautions must be taken when using it.

First of all, make sure that your carafe or kettle filter is clean by pouring in the amount of water you need. Then close the lid properly before plugging it into an electrical outlet and select the function of your choice and the temperature level and then press the start button. After the automatic shutdown, it is recommended to unplug the device before emptying it.

To protect yourself from the effects of water, avoid boiling the same water twice in a row. Be aware that when water is boiled, it turns into steam and becomes loaded with particles with a tendency to decompose. The water then contains harmful substances such as nitrate and fluoride. Therefore, be sure to empty your container before each use.

The different types of adjustable temperature kettles

Choosing a kettle with adjustable temperature will depend precisely on your use and needs. Moreover, the different types of kettles are distinguished by the function of variation and adjustment of temperature. To this end, there are three types of adjustable temperature kettles.

The step-temperature adjustable kettle

The step-temperature kettle has a temperature feature that allows you to choose between plus or minus 5°C from a selected heating level. This type of kettle is mainly classified as an intermediate kettle.

It is the best alternative to the classic or traditional kettle. It allows for better management of different temperatures over several levels of variation, unlike models with thermostats with a single factory setting of 100°C.

The precise temperature adjustable kettle

Similar to the previous kettle model, the precise adjustable temperature kettle is distinguished by a well-defined temperature level.

This type of kettle allows a function to heat water to the temperature to the nearest degree based on the pre-selected setting. In general, the preset temperatures will vary on several levels ranging from 3 to 7 selections between 40°C to 100°C depending on the model.

The precise adjustable temperature kettle is logically more expensive than the stepwise adjustable model. This kettle has been designed mainly for the preparation of hot drinks or precisely for tea. It allows to reveal the maximum aroma of each tea with all the aromatic complexity.

The temperature adjustable kettle with prerecorded programs

It is a model of kettle designed with programs for different preparations of hot drinks. Very practical, this kettle has pre-recorded programs and calibrated from the manufacture.

These pre-installed programs allow you to heat up a perfect and optimal temperature for green tea, black tea or infusion in one click. There are even models with a program for the preparation of iced tea or other types of drinks.

Indeed, this type of kettle offers a higher level of practicality and precision. But its only drawback is that the price is a little more expensive than other models.

Adjustable temperature kettle or electric teapot

Kettle with adjustable temperature

Indeed, the adjustable temperature kettle has the same general characteristics as the simple electric kettles. However, they stand out for their manufacturing materials and the presence of electronic controls.

Some models even feature a temperature control screen with multiple buttons. This kettle allows you to have different choices on the heating temperature depending on your needs or your preparation of hot beverage. In most cases, the choice of heating temperature ranges from 40° to 100°C, but this will also depend on each model.

To its advantage, the adjustable temperature kettle is still not limited to the consumption of hot drinks. But it also allows you to bring your water to a boil with a quick heating time. Besides tea and boiling water, it can even make caffeinated drinks, Japanese noodles, soups and other drinks.

Electric teapot

The electric teapot is distinguished primarily by its design. Essentially designed for tea lovers and fans, it offers the advantage of managing both the heating temperature and the brewing time automatically. The electric teapot has predefined modes for each type of tea with a certain temperature precision to preserve the aromas.

The manual mode is also available if the pre-set functions do not meet expectations. Mostly made of heat resistant glass, these devices have a built-in movable tea filter to ensure precision to a quality aroma.

To its advantage, the electric teapot offers an economical and practical aspect. It allows you to manage the time and temperature of the perfect tea brewing. Its only disadvantage is that its functions are limited to the preparation of tea.


Choosing between an adjustable temperature kettle and an electric teapot will depend on your daily needs. For multipurpose use, the adjustable temperature kettle will be a better asset for your investment.

It will allow you to make several types of hot drinks and even noodles. But if you are a big fan and connoisseur of tea with specific flavors, the electric teapot will be a better ally to satisfy your needs and expectations.

Why choose a kettle with adjustable temperature?

Very practical, the adjustable temperature kettle offers several favorable criteria for daily use.

Fast and economical

The adjustable temperature kettle allows you to reach a heating temperature in less time. Some models reach the heating temperature in less than a minute. Thus, the kettle saves time and energy.

Practicality linked to ease

With its adjustable temperature functions, this equipment offers the advantage of having freedom in heating water. It allows you to choose between lukewarm water, hot water or boiling water. Indeed, it is equipped with a temperature variation function at different levels to adapt to the temperature according to your choice of selection.


For hot beverage lovers, this is a very important aspect in order to have an ideal temperature at brewing. A difference in heating temperatures can have an impact on the flavor and aroma of your drink.

With the smart programmer function and the automatic shut-off feature, a temperature controlled kettle will bring out the full flavor of your brew whether it is tea or coffee. Varying temperatures from one brew to the next is a pretty effective trick to allow a substance to release all the flavors it contains.

The availability of a keep warm function

The adjustable temperature kettle allows you to keep your water or beverage hot for a longer period of time thanks to a keep warm function. This heat retention will vary depending on the kettle model.

The minimum hold time is usually 30 minutes, but it can be as long as 2 hours. This gives you plenty of time to consume your beverage at the ideal temperature and save you from having to turn your kettle back on to heat it up.

Versatility and safety of use

Indeed, a kettle with adjustable temperature has many assets to satisfy us in the kitchen. With its function of heating to boiling, this device also allows you to make noodles, soup, cook dehydrated sauces or cook dry pasta and many others.

As far as safety is concerned, this equipment has an automatic stop function when empty and turns off automatically when the carafe is detached from the base. This function protects against electrical surges and certain accidents that can be caused by wrong manipulation of the machine.

The best brands of adjustable temperature kettles

In our opinion, the best brands of adjustable temperature kettles in 2022 are :

Riviera & Bar

Founded in 1954, Tefal is a French company that joined the SEB group in 1968. Basically a reference brand in terms of kitchen utensils, Tefal now presents a wide variety of clever, innovative and practical products for everyday use. The brands kettles are distinguished above all by their robustness combined with excellent performance and innovative design.

Originally American, the Aicok brand is a very recent company founded in 2015 by a small group of workers from Google. One of the best references in North America and Europe, the brand has established itself in a record time on the home appliance market. Melitta is a German company founded in 1908 and specializes in the manufacture and distribution of small household appliances and accessories for household products. The success of the brand comes from the quality of the different ranges of coffee machines. Focusing more on innovation, Melitta is known for manufacturing high quality appliances with customizable options for the preparation of different hot drinks.

Created in 1937, Moulinex is a French brand that is one of the major references in the field of household appliances. Bought by the SEB group in 2000, Moulinex keeps its name but sells its products on behalf of the SEB group. As far as adjustable temperature kettles are concerned, the brand makes available on the market several models targeting all price ranges to be accessible to all. Its products are mainly known for their stainless steel construction and high performance. Moulinex is also a reference in terms of practical and robust products.

Riviera & Bar is a French brand created in the 70s. This brand is making a reputation for itself in the field of designing high quality culinary arts objects.

Descale your kettle in a natural and ecological way

Limescale build-up is one of the main causes of kettle wear. After several uses of your adjustable temperature kettle, it may get covered with scale with the effects of water. Often we always tend to spend more money to get appropriate industrial descalers to make it easier for us.

But you should know that there are much more natural and ecological alternatives. In this regard, we can cite the lemon with its composition of citric acid, white vinegar, coca-cola, baking soda or sodium bicarbonate and the clay stone by moistening it with sponge.

Adapt the power of your kettle to the capacity for a fast heating

It is essential to know that the more the kettle has a large capacity and the more power it will need to heat the water to a minimum duration. For example, a kettle with a capacity of less than a liter only requires about 700 watts of power to be able to reach the maximum temperature at a duration of less than 15 minutes. In general, kettles with a capacity of more than 1.5 liters require at least 2200 watts.

Clean and maintain your kettle with adjustable temperature

Try to always use filtered water in your kettle. In general, a kettle is simple to clean and maintain. To prolong its life, it is necessary to clean it frequently and properly.

To avoid scaling, avoid letting water or tea sit in your kettle's jug for too long. After each use, try to always rinse it. Then sponge it down with a little vinegar and rinse it well before placing it back on its base.

Caution: Never put your electric kettle in the dishwasher to clean it. This type of equipment has electrical and electronic components that could be damaged. Instead, adopt a gentle sponge cleaning with a little dishwashing liquid.

Succeed a good tea from a kettle with adjustable temperature

Contrary to our pot preparations, you should never boil the water for tea, except when preparing a green tea with mint. From there comes the usefulness of the adjustable temperature kettle, you just need to select and heat it to the right temperature. Each type of tea has its own temperature to provide the ideal aroma.

Black teas require 95° water, green teas need 60° to 90° water and yellow and white teas release all their flavors in water between 70° and 80°. A kettle with adjustable temperature will allow you to easily reach the right temperature.

In addition, you should pay attention to the length of time you brew your tea because a tea that is not brewed very long contains a lot of theine, unlike a tea that is brewed very long. If you want to drink a stronger tea, it's better to add tea leaves to your drink than to let the tea brew too long, as brewing too long makes the tea taste pungent.

Determine the temperature of the water according to the boiling point

The most commonly cited tip for determining the water temperature is to observe the progression of bubbles in the boiling water.

Conventional wisdom compares bubbles produced at low temperatures for green and white teas to smaller crab eyes, while Chinese oolong teas require bubbles compared to medium-sized fish eyes and the large bubbles from a full boil are called dragon eyes.

This method easily defines temperature differences, but works best when the water is visibly boiled in an open kettle with a wide opening. In a closed kettle, it is impossible to see the bubbles except in a glass kettle.


What type of water is ideal for a temperature control kettle?

The main point to remember is that the presence of chlorine and lime in the water should be minimized or excluded altogether. Prioritize oligo-mineral waters and spring waters with less minerals and rich in trace elements. If you use tap water, make sure you have a filtering system.

What are the most common failures of a temperature control kettle?

Abroken kettle is a kettle that no longer heats or cannot reach the selected heating temperature. These problems are caused by several factors that could be related to a power failure, a faulty cord or even instability of the switch.

Does a temperature control kettle require a minimum recommended amount of water?

In fact, all kettles are limited to a minimum amount of water to avoid a failure causing a breakdown. But this will depend on the maximum capacity of the appliance. For example, for a 1 liter kettle, it is recommended to put no less than 300 ml of water in use. For a 1.7 liter kettle, the minimum recommended amount will be about 900 ml.

Can a temperature control kettle be used to boil milk or anything other than water?

It is best to reserve the use of your kettle for heating water only. Other liquids such as milk are not suitable. Milk is a liquid that does not evaporate like water and increases in volume when it boils. At this level the milk could overflow from the carafe and cause a short circuit in the electric base.
