How to choose an electric kettle Thermos for home

For the same scheme as that of the kettle is located inside Thermo heating element. The housing has the shape of a half-cylinder. Water is poured into the flask and turned on "start". The heater boils the water and keeps the temperature of 95 degrees for several hours. Then the heating level is reduced to 70 degrees and supported day. Housing at this time remains cold.

types of devices

Airpots different type body heating element and other parameters. On a set of characteristics they look like electric kettles and instantaneous water heaters.

The material of the shell:

• plastic;
• ceramics;
• glass;
• metal;
• combination of materials.

flask volumes ranging from 2.5 to 8 liters.

Power is from 0.6 to 1 kW.

Use different types of heaters:

• Disc heater.
• Heating coil.
• Outdoor heater.

Expanding the functionality of devices, manufacturers add the following functions:

• timer and an acoustic signal;
• delayed start function;
• clear display with different modes;
• display backlighting;
• self-cleaning function;
• pouring a further embodiment;
• with adjustment of the heating temperature;
• lock against accidental operation and the inclusion of free water;
• removable strainer.

Characteristics

The instrument parameters are closely related. If you buy a large amount of Thermo, its capacity will be larger, otherwise the water will boil long.

Power

Power - an indicator that affects the time the water heater. The more power an electric kettle, the longer it will retain heat. The standard capacity of the device 600 - 900 watts. In heating mode, the heater power 30 - 40 watts.

volume

The average volume of the tank is 3-4 liters, it is twice more than in the ordinary kettle. This amount of water is enough for tea for a family of 5 people.

bulb material

Choosing inner flask need careful consideration, because it is in contact with the water you drink.

ceramic coating It does not change the taste of the water when heated.

Stainless steel strong, but when washing on it can develop scratches.

Glass - good clean and resistant to scratches. Minus - the fragility of the material.

Flask made of stainless steel, coated ceramic layer. Higher price models, but sufficient bulb strength and reliability.

Heating element type

Typically, the device has two heating elements, one for boiling, sufficient to maintain the second temperature. There are devices in which is mounted a single combined element.

To protect the heater from corrosion, it is applied to chrome, silver, nickel plated. Some models even gilding is applied.

To use the internal heating or closed helix and a closed disc. Termochaynik open spiral has a lower price, the service life of the element is less, because it is constantly in contact with water, and over time, covered bloom.

Devices with a closed spiral is easier to clean, but they are very noisy and consume a lot of electricity. Disc cell operates more efficiently and without noise.

water supply type

Termochaynik is heavy and rather big dimensions. Pour boiling water as a tea difficult. Therefore, the design provides for manual or electric pump. The mechanical pump does not require electricity. The liquid injection is carried out by pressing the button repeatedly.

How to choose

Most termochaynikov easy to maintain and reliable. The most economical device has a large capacity and a minimum at the boil to maintain it in the form of heat.

Thermo need to choose, taking into account several criteria:

• Power. It affects the rate of water boil. It is recommended to take more powerful.
• container volume. It is necessary to take into account how many people will use the device daily. Housing, where two people live, three-liter will be sufficient; Office rational purchase the largest volume.
• Time save hot water. Usually the device is incorporated several modes maintain the desired temperature. In cheaper embodiment only one mode.
• heating lock. When the water is low, the device will automatically stop working, preventing overheating.
• Menu on the display should be clear and understandable in Russian.
• The lid must be closed easily, and not to let steam.

Review of the best representatives

Thermo - receiver is a modern Russian samovar. Feedback from customers to review several models were selected.
