Electric has become an essential subject of a set of kitchen equipment. In choosing this, there are some nuances seem to be a simple device. Should pay attention to the materials used, the type of heating element, container, power, design and weight.
materials
Electric kettles are made of the following materials:
- Plastic - a cheap and practical material. Plastic bad conductor of heat, so the surface is difficult to burn, and the water cools down a long time. Poor quality plastic gives the water an unpleasant odor. He is not strong enough, fade, the surface tarnish.
- Stainless steel - environmental friendliness, durability, strength, hygiene. Kettles Stainless noise, cost more of them can be burned.
- Glass It has all the positive properties of the metal. Through a transparent material is clearly visible water level. Disadvantages - the fragility, the formation of scale.
- Ceramics - the leader in originality appearance, heat-saving features. Cons - fragility, small capacity, heavy, high prices.
heating elements
In use the kettle spiral and circular heating elements. Spiral heating elements have the shape of a coil, located inside the housing just above the bottom, disk - embedded in the bottom.
It is believed that faster disk kettles heated water, but it's a moot point - the laws of physics tell a different story. Kettles with circular heating elements easier to clean, but expensive and noisy.
Power of heaters varies in the range of 0.3 - 3 kW. It depends on it while boiling water. This figure should match the capacity of the kettle. For common models of 1.5 liters is optimal power 2 kW.
Additional functions
The presence of additional functions make use of tea more comfortable, but the purchase costs of expensive models are not always justified.
- Whether one, two water purification filter installed in certain models. This improves the quality and reduces the formation of scale. Practice shows that the use of a stand-alone filter convenient.
- Temperature setting - a useful feature for connoisseurs of tea and preparing baby food.
- Disabling with insufficient water blank tea protects against damage.
- Sound signal is turned off. All electric kettles are switched off automatically, but forgetful people reminder can not hurt.
Knowing the criteria for selecting an electric kettle, buy the correct model is not difficult. Capacity selected based on the number of family members, design - based on preferences. The cheapest models are plastic pots with spiral heating elements.
If you are afraid of getting burned, do not buy the metal when weight is important - piece of pottery. The rest - the choice is yours.
