Kettle with thermostat

Electric kettle with thermostat

Some of the first electric kettles appeared in the late 19th – early 20th century. Over time, their design, functionality improved.

Now the range of electrical devices is so large that it is difficult for a modern buyer to choose the right option for himself. Below is a brief overview of electrical products, their positive and negative characteristics.

Characteristics of kettles with thermostat

What is the difference between ordinary electric kettles and the same ones, but with a built-in thermostat?
A fundamental feature of the operation of kettles with a thermostat is the software control of the thermostat.

Such models allow you to accurately set the liquid heating temperature on the LCD screen.

The presence of a regulator allows you to maintain the desired temperature, periodically turning on after the water has cooled.

The main components that distinguish thermo-electric kettles are:

  1. Thermometer with sensor
  2. Memory block with recorded action sequences
  3. Control panel for setting operating modes
  4. The electronic board

This device will be a useful acquisition for lovers of a variety of drinks. The control panel has the following modes:

  • 40 ° – for the preparation of infant formula;
  • 60 ° – for brewing white teas;
  • 70 ° – 85 ° – green teas, red (not fermented);
  • 85° – 95° – flower, yellow leaf non-fermented teas;
  • 95° – 100° – red teas, roasted, leafy oolongs, fermented pu-erh, herbal teas.

The resource to heat the liquid to the required temperature is the advantage of the thermostatic electric kettle.

The automatic thermostat starts heating the liquid to the required temperature when it cools down.

That allows you to always have hot boiled water.

On the other hand, this is a disadvantage of a kettle with a thermostat, due to the fact that electricity consumption increases due to periodic switching on, and this is not always necessary.

The main characteristics that you should pay attention to when buying:

  1. Types of thermostats
  2. Capacity
  3. Power
  4. Housing material
  5. A heating element
  6. Security
  7. Filter
  8. Retractable cord
  9. Switch-on lock when the lid is open, without water
  10. Backlight at work


Thermoregulators of electrical products are of two types: stepless or stepped. With the help of stepless regulators, it is possible to smoothly set the liquid heating temperature with an accuracy of tenths of a degree.

Step controllers make it possible to regulate the temperature only in certain values, in increments of about 10 degrees.

It is worth deciding on the control: for some products, the temperature control buttons are located on a special stand, while for others, on the case.



By volume teapots are distinguished:

  • Small – up to 1.5 liters
  • Medium – the most common -1.5 – 2.5 liters
  • Large – 2.5 – or more.

It is worth choosing based on your needs and on the number of people who can use the device at the same time. The larger the capacity, the more expensive the item.

For a family of 3-5 people or for an office, you need to choose a product with a capacity of about 2 liters, and for a family of two, 1.2 liters is enough. The most common models have a volume of 1.7 liters.

By power, electric kettles are divided:

  • up to 1500 W
  • from 1500 W – 2500 W
  • over 2500 W

In order for the water in the electric kettle to heat up faster, you should choose a more powerful model.

For a 1.2-liter kettle, a power of 1.5-2 kW is acceptable, but it is advisable to choose 2-liter types with a power of at least 2.5 kW.

When studying the “power” parameter, be sure to pay attention to the quality of the wiring in the room where the device will be used.

If the wiring condition is not good enough, you should choose a brand with a lower capacity. The optimal power is 2-2.2 kW. The boiling time of the liquid depends on the shape of the product. The wider the bottom of the appliance, the faster the water will boil.

Types of kettles with thermostat



Plastic or iron housing may leave unpleasant water. The glass product does not contain nickel or formaldehyde, so the water will not have an extraneous taste.

Electrical appliances made of plastic are made of polypropylene and polycarbonate. Polypropylene is denoted by two Latin letters PP, it has a sharp specific smell, when heated, water dissolves harmful substances in itself – formaldehydes.

Polycarbonate is denoted by the letters OTHER, more durable high-quality plastic has a less pronounced odor.

It is more resistant to high temperatures. At high temperature loads, it does not emit harmful substances.

Plastic ones are cheaper and also the most common. Plastic is quite durable, but eventually loses its appearance.


On environmental grounds, metal is more durable than plastic. Iron electric kettles are more durable than their counterparts, as they serve for a long time and retain an unchanged appearance. In a metal model, you should not leave water overnight, the metal oxidizes, and oxidation products (iron oxide) will get into drinking water.

It is better to choose a product made of stainless steel, without aluminum impurities, so that harmful substances do not get into the water.

Such a product should be carefully cleaned so as not to damage the surface, due to damage it will begin to oxidize.

Stainless steel is a very strong material, so it is more difficult to break an iron electrical appliance than one made of plastic. Now the assortment of household appliances stores represents a number of different types of goods.

There are combined varieties: a metal block is coated with plastic, due to which it receives the advantages of plastic products.

Metal electric kettles heat up intensely, which is dangerous for children. The negative quality of metal teapots is that they are more expensive than those made of plastic. A metal electric kettle filled with water can weigh up to three kilograms.

In metal products, sometimes there is no water level scale. The presence of a scale leads to the risk of leakage of the device. Metal prototypes are noisier in operation.


Glass material is environmentally friendly. But you should pay attention to the details of the glass product. They are made from plastic and metal. Plastic or metal parts must comply with acceptable standards.

(Plastic should be polycarbonate and metal should be stainless steel.)

It is better to choose a product made of thicker glass. In such a product, boiled water will be tastier than in the rest.

By weight, glass and metal products are heavier than plastic ones.
According to the strength of materials, the most durable is an iron electric kettle. If you miss a glass or plastic device, it may break.

heating elements

a heating element

  • Closed heating element
  • Open heater
  • Spiral (open)

Such an indicator as fire safety depends on the type of heating element. Boiling time depends on body materials. In a metal product, the liquid heats up faster than in a teapot made of glass or plastic. And if the heating element is open, the liquid will not boil soon.

With closed TEN

They will last longer, as the heating element is insulated from water – it is built into the bottom of the case.

Such prototypes are considered safe to use.

The time of heating water is affected by the volume of the bowl, the size of the heating element, its power.

With open heater

An open heating element is a spiral located at the bottom of the kettle. The disadvantage of devices with an open type spiral is fragility, a low level of safety. The spiral quickly becomes covered with scale, which is almost impossible to clean. In addition, it is difficult to wash such a kettle.

To prevent the electric kettle from igniting, a minimum amount of liquid (200 grams) should be poured into it. It is necessary to focus on the mark of the minimum amount of liquid indicated on the scale by the letters MIN.

Water filters are removable and built-in. The first allows you to easily remove it for descaling.



Plastic teapots are recommended to be used no more than 2 years. Metal no more than 5 years. Glass up to 10 years of operation. Otherwise, after the expiration of the specified period, even in a kettle of the highest grade of body materials, harmful substances will begin to enter the water.

It is very important that when choosing a brand, pay attention to the quality of the cable. It should be strong enough, heavy, thick. The cable must be marked with a cable cross-section, technical indicators and manufacturer.

The length of the cord for most models is 0.6-1.3 meters. Short and long are equally inconvenient, so it is better to purchase products with a medium-sized wire. It is convenient if the cord is retracted into the base.

If the lid is open in the kettle, there is no liquid, the appliance should not turn on (a useful shutdown function without water).

And also when the liquid boils completely, the device should turn off by itself. For safety reasons, the product must have the function of blocking the lid, in order to prevent it from falling out, so as not to spill boiling water on itself.

Lighting is an important part. It usually comes with LEDs. It signals the presence of power, or the start of heating (in different models in different ways).

It happens that the color of the glow changes depending on the mode, this is very convenient. You can also find a prototype with backlight, gradually taking on a different color according to the temperature of the liquid. It turns out that the color changes smoothly as it approaches the boiling point.

Disadvantages of kettles with a thermostat


The more components in the device, the more functions it has, the more likely it is to break.

Increased power consumption (do not leave the device on if you are not going to use it in the near future otherwise the device will heat up in vain)

The high cost of species with thermoregulation function

The probability of breakage of the temperature controller increases, therefore, over time, the thermostat may fail: it will no longer maintain the desired temperature

How to choose

With the right choice and thoughtful use, models of electric kettles with temperature controllers will save significant energy consumption.

It is necessary to purchase models of products with thermostats only in reliable, branded stores.

For low-quality models, it is typical: a long boiling time, an unpleasant smell inside the device that appears when heated, due to the use of low-quality, cheaper materials used to make the case.

So that the electrical device does not quickly fail, it is necessary to use high-quality models. The decision to purchase a kettle with a temperature controller should be made if you need a constant supply of hot, boiled water.
