What is better – a kettle or a thermopot?

It is impossible to clearly state which is better – a kettle or a thermopot, as each device has its own advantages and disadvantages. When choosing between these devices, consider the conditions in which they will be used, how often they will be used, and the desired volume of hot water.

These two devices are only similar in one aspect – they both provide boiling water. However, the process itself is different.

The main advantages and disadvantages of the devices

Pros and cons exist for both devices. The advantages of a traditional electric kettle are:

• It can boil 2 liters of water in just 1 minute;
• It is compact and convenient to carry around;
• There are many models available with different designs, shapes, and sizes;
• It has an affordable price.
• However, the maximum volume is usually limited to 5 liters;
• The process of boiling water requires a significant amount of electricity;
• Cheap models may not last long and can develop leaks or fail.

Thermopot (or potter) has its own positive qualities:

• It can boil water like a kettle and also maintain its temperature like a thermos;
• It is more spacious, with a capacity of up to 8 liters;
• It consumes moderate amount of energy;
• Some models are programmable, allowing you to set the desired time for heating the water.
• The process of using this device is simple. You just need to bring the container to the spout and press the button, and water will be poured into the cup.
• Generally, this device is larger in size compared to a kettle.
• Additionally, it tends to be more expensive to purchase.
• Furthermore, it takes a longer period of time to boil water when using this device. Therefore, if you are making tea, you will need to wait a bit longer.

Comparison of the parameters of the kettle and thermopot

To determine which is superior, a thermopot or an electric kettle, it’s essential to compare these two devices based on their main operational features.

The primary factors that differentiate them are: the operating principle, design, power consumption, and intended purposes.

A kettle is an electrical device designed to rapidly heat and automatically shut off when water boils. The duration for which the water cools may vary depending on the surrounding temperature, but typically it takes approximately 30 minutes for the water to cool down completely.

A thermopot combines the functions of a kettle and a thermos in one convenient package. The unique advantage of a kettle is its portability, as it can be easily transported from the kitchen to the bedroom. Kettles typically have an average volume ranging from 0.5 to 3 liters.

On the other hand, a thermopot is designed with a larger volume, typically ranging from 2.5 to 6 liters, and is mostly stationary. The main difference between these two devices is that a thermopot incorporates both the functions of a kettle and a thermos in a single case. It not only heats the liquid but also has the capability to keep it hot for up to 15 hours.

While the water in a thermopot may cool down slightly, it generally remains above the temperature of +70 degrees Celsius, which is more than sufficient for making tea or coffee.

Additionally, many thermopot models include an extra heating element, known as a TEN, which is responsible for heating the water. However, it is worth noting that it takes longer to boil water in a thermopot compared to a traditional kettle, typically requiring around 15 to 30 minutes. The liquid is dispensed by either a pump, an automatic feature, or manually.

Energy Consumption

A kettle is considered to be more economical due to its energy-efficient operation. Unlike a thermopot, which constantly uses energy to maintain the temperature at preset values, a kettle only consumes energy when it is actively heating the liquid.

The kettle’s heating element, if it functions as a thermos, will use electricity when it is turned on. Moreover, the kettle has a larger volume compared to other devices, which is also considered. It is essential to know the energy consumption of the thermopot on a daily basis. For instance, if water is boiled and needs to be maintained at a certain temperature throughout the day, it will consume 90 watts of power. With a volume of 6 liters, it will consume 3.06 kW per day. Power characteristics of each model differ based on the type of heating element installed.

Volume and power

Thermopot for 5 liters

For a small family where everyone works during the day, the kettle is typically turned on twice daily to boil water in the morning and evening. A 5-liter capacity is sufficient for this purpose. However, in a larger family with children, the kettle would have to be used more frequently.

That’s where the thermopot comes in. Firstly, it is bulkier, and secondly, it keeps the water hot, eliminating the need to wait for it to boil again.

The speed at which the device can boil water depends on its power. Electric kettles typically have a power range of 1800-2400 watts, while thermopots range from 600-1000 watts.

If you need to quickly prepare a hot drink, opt for a kettle. However, if you prefer to keep your water hot for longer periods, the thermopot is an analog of a thermos and is a perfect choice.

Constructive differences

The filtration system of the thermopot is an important consideration when choosing a device. Understanding how the system is designed and how it functions can help in selecting a more convenient and energy-efficient option:

• An electric kettle consumes energy only while boiling water, whereas a thermopot needs to remain plugged in at all times to maintain the desired temperature. However, there are simpler models available without heating elements, relying solely on heat-resistant walls for heat preservation.
• Compared to a regular kettle, a thermopot is heavier and larger in size.
• A thermopot features a filter that requires replacement every 2-3 months.
• Unlike an electric kettle, which can become very hot during operation, especially if made of glass or metal, a thermopot is a safe device as its walls retain heat and prevent heat from escaping, reducing the risk of burns.

Functional characteristics

The kettle has a temperature adjustment function.

Usually, basic electric kettles do not have specific features. However, more expensive models offer useful additions:

• A timer for setting the kettle to turn on automatically;
• A lock feature that prevents the kettle from operating when there is no water in the container. This is especially useful for families with small children who might accidentally turn on the kettle;
• A clock and alarm clock function;
• A temperature adjustment feature for precise heating;
• A remote control option, allowing you to start the kettle remotely using a smartphone application.

In terms of functions, thermopots are more interesting as they can constantly maintain the desired temperature. Even basic models usually have a thermo regulator with 3-4 modes.

There are also additional options available:

• A "child lock" feature that prevents the thermopot from heating an empty container;
• Adjusting the portion size for a single serving;
• Locking the lid in place;
• Adjusting the temperature;
• Indicators that light up;
• Having a second reservoir.

Purposes of use

The primary function of a typical electric kettle is to rapidly heat water, making it ideal for individuals who prefer quick beverages. In just a matter of minutes, this appliance can efficiently bring several liters of water to a boil.

Having a child in the family makes the thermopot an indispensable appliance.

Kettles are powerful appliances, consuming a significant amount of electricity with a power ranging from 1000 to 3000 W. Therefore, they are more suitable for small families that occasionally need boiling water.

A thermopot is a unique piece of equipment that combines the functionality of a kettle with that of a thermos. It can heat water and keep it hot for up to +90 degrees Celsius for an entire day.

This is achieved through the use of thick walls and advanced thermoregulator modes. However, this also means that the size and weight of the appliance are increased.

When there is a baby in the family, a thermopot becomes a valuable device. It provides warm water, perfect for preparing baby formula without the need to boil it. Additionally, it can come in handy for those who enjoy gathering in large groups for a cup of tea – with a volume ranging from 3 to 5 liters, there is enough for everyone to enjoy.

Thermopots are gradually replacing the traditional electric kettles in recent years, although they cannot completely replace them. They are a great purchase for large families or offices. They are particularly suitable for environments where tea, coffee, or baby formula are frequently prepared and consumed.

These devices are specifically designed for such situations, as indicated by their larger capacity. They are also useful in summer houses or gardens where power outages may occur. The thick walls of the thermopot help maintain the ideal temperature of the liquid.

If you don’t always need instant access to boiling water, then there is no real need to invest in a thermopot.

In such situations, it will not just be expensive, but also ineffective, so it is preferable to consider a regular electric kettle. This is a straightforward and user-friendly device that can easily heat up several liters of water in just a minute.

A thermopot and a kettle are both helpful household appliances, but they are not suitable for every situation. Each appliance has its own energy consumption rates. For everyday use, no more than 5 times a day, a thermopot would be too costly.

It would be useful if there is a need for hot water for a large number of people, around 10. However, for simply boiling water for tea, for a small family, a regular electric kettle will suffice.
