Thermopot is a hybrid of a kettle and a thermos, which can perfectly replace a bulky cooler in the office. Its main task is not easy to boil water, but to constantly keep it hot. Before choosing a thermo pot for your home or office, you should immediately decide – if you need boiling water to make 3-4 cups of tea or coffee a day, then you should not overpay, it will be enough to buy an ordinary electric kettle, it will easily cope with this task. Another thing is a large family, a small cafe or office, in which case the thermopot fully justifies its purpose.
Purpose and device
Thermopot eliminates the main disadvantage of an electric kettle – it heats up quickly, but also cools down quickly. Therefore, you have to wait until it boils again. As experience shows, thermopots also save electricity. They not only constantly heat up, but also, thanks to special thermal insulation, do not allow the water to cool down too quickly. True, the device turns out to be much larger and heavier than an electric kettle, it requires stationary placement and a permanent connection to electricity. In addition, water must be poured into it using a special container / watering can; it cannot be substituted under a stream from a tap. The supply of boiling water can be either automatic or manual.
Immediately select the place where the device will stand and measure the distance to the outlet so that the length of the cord is enough. Well, if there is a special compartment where you can hide the extra length of the cord.
Consider the main parameters that you should pay attention to when choosing a thermopot.
Now on the market you can buy a thermal pot with a capacity of 2 (it simply does not make sense to take less, otherwise you will have to add water very often, and the thermopot itself will be used inefficiently, actually working in electric kettle mode) up to 8 liters. The choice of capacity depends on how many people need to be provided with hot water. Usually, the volume is chosen based on the norm of 1 liter (1.5 for big fans of hot drinks) per person. Then it will be possible to refuel at the beginning of the day and the rest of the time just use it.
Power affects the heating rate, the higher it is, the faster the water boils, which is especially important for bulk thermopots. The maximum recommended power is 1000 watts.
Now only in cheap models of little-known manufacturers can you find an open spiral in a tank for heating water. Almost all modern models of thermopots have heating discs.
Separately, it is worth noting the models of thermopots with two heating elements (heater). One is powerful, which allows you to quickly heat water. The second is to work in standby mode in order to maintain the set temperature. This design allows not only to maintain the required temperature, but also to further save energy.
The body is made of metal, plastic, glass, or combinations thereof. It is much more important what the tank is made of, in which water is boiled. In cheap models, it is made of food-grade plastic, so over time, water can acquire a specific taste. In addition, the service life of such models is short. Particular attention should be paid to the temperature of the case – if the case heats up when checking in a store, then the thermal insulation is poorly made. Therefore, the thermopot will turn on more often to heat the water – and this is an additional consumption of electricity. In good models, the case practically does not heat up during operation.
In high-quality models, the tank is made of glass (it is more suitable for water, but requires careful attention due to its fragility) or metal.
Water supply method
In different models, the methods of supply are different – it depends on the type of pump (pump) installed:
- Automatic – an electric pump is installed in such a thermopot, and the water itself begins to flow after the cup is placed in a certain place.
- Semi-automatic – an electric pump is also installed here, but the flow starts after pressing the button.
- manual – water is supplied by a mechanical pump, the user himself needs to press the lever or handle several times. The advantage of this method is that the supply occurs even when the thermopot is disconnected from electricity.
The set of functions in thermopot models may vary, the more additional functionality, the more expensive the model will be:
- Temperature selection – the adjustment allows the user to set the temperature of the water to be maintained. The standard temperature range is 50°C to 90°C. The adjustment can be either stepwise, setting only certain temperature values through a given number of degrees (most often – after 10 ° C), or smooth.
- Adjustment of the portion of water – available in thermo pots with automatic water supply, allows you to pour from 120 to 300 ml of water at a time (several values are available).
- Interlocks – at least one (and it is available in almost all models) – turning off the device when the water level in the tank is insufficient. Another blocking is protection against overheating. If the family has a small child, then a child lock is required. The top cover has a special latch that blocks its accidental opening during water heating.
- Two reservoirs – in one there is constantly boiling water, and in the second the user can set the required temperature himself.
- Digital display – in most cases displays information about the current temperature value. In addition, it can inform the user about what processes are currently running.
- Turn-on timer – allows you to set the turn-on time, for example, the water will boil by the return of family members home or by the arrival of employees at work.
- Built-in filter – allows you to purify water from impurities, although this may reduce pressure and increase the time it takes to fill a cup. At the same time, the filter will have to be washed or changed monthly, and in some models it is structurally placed not very well, to get to it, you will have to disassemble a significant part of the device.
- Self-cleaning – some thermopots have a function of signaling the need for descaling. As in the case of electric kettles, you can use special tools, or you can get by with folk methods.
To avoid scale formation, it is necessary to use filtered (prepared) water.
