Basic Knowledge of Electric Kettles

1. The power of the electric kettle is so large, will it be very power-consuming?
Answer: The power is high, but the heating speed is very fast, and the thermal efficiency is very high.
How much electricity does a kettle use to boil a pot of water, depending on the model?
Answer: 1800W/1.7L water for about 5 minutes, power consumption is about 0.14 kWh; electricity cost is less than 0.1 yuan, which is cheaper than using gas.
3. Is more power always better?
Answer: 1800W/1.7L water boils in about 5 minutes, consuming about 0.14 kWh; 1000W/1L water boils in about 5 minutes, consuming about 0.08 kWh.
What is the difference between an electric heating tube and a home heating plate? Which one has a better heating effect?
Answer: The difference between the electric heating tube and the heating plate is that the electric heating tube is heated in water, while the heating plate heats from the bottom of the water; the heating efficiency of both is essentially the same, exceeding 92%.

Why does the heating element in an electric kettle have a shorter lifespan than the heating plate?

Answer: The longer service life of the heating plate is due to its larger heat conduction area and smaller heat load; whereas the heating tube has a larger heat load, and the accumulated scale is difficult to clean, which can easily cause overheating and shorten the service life of the heating tube.
Why is it that stainless steel heating plates are less prone to scale formation?
Answer: The polished surface and large surface area of the stainless steel heating pan make it less likely for scale to accumulate, and it is easy to clean; however, scale on the heating tubes is difficult to clean once it accumulates.

What is a thermostat?
Answer: The temperature controller is installed together with the heating tube or heating plate, automatically disconnecting the power supply when the water boils, and at the same time, it serves as a protective measure against dry burning in the absence of water, preventing accidents such as fires. The temperature controller for the kettle is akin to the "heart" of a human or the engine of a car.

What are the advantages of precise temperature control?
Answer: The advantage of precise temperature control is that it can accurately sense when water boils, ensuring that it boils and does not boil for too long; simultaneously, it can accurately sense abnormal conditions such as dry burning and receive protection in time.

9. Does the electric kettle keep hot longer in stainless steel or plastic?
Answer: It's basically the same. The plastic kettle is slightly longer because the stainless steel surface cools faster.
Will plastic water bottles deform over time and are they toxic?
Answer: The plastic water bottle is made from food-grade heat-resistant plastic that has national health approval, which is non-toxic and will not deform.
Will the base of an electric kettle conduct electricity when it is plugged in?
Answer: No, the electric kettle products have been designed to meet national safety standards and have passed national safety certification, so they will not cause personal harm.
What is a steam sensing device and what are its benefits?
Answer: The steam sensing device is a function held by the temperature controller of an electric kettle, which acts when steam is produced from boiling water to disconnect the power supply, ensuring that the water does not boil excessively or pose a risk of drying out.

How is the water quality after boiling? Will there be any unusual odor?
Answer: The water boiled by an electric kettle is no different from that boiled on a general gas stove, it is just that the energy source is different. The quality of the water will not change. The materials used in the Halfball electric kettle are all national food-grade materials, and there will be no unpleasant odor or harmful substances to the body.

14. The super insulating series in electric kettles, will the quality of the water change if it is insulated for a long time?
Answer: The insulation function is only maintained by low-power heating, and the insulation will not boil the water, and the quality of the water will not deteriorate due to the insulation heating.

How long is the typical lifespan of a kettle?
Answer: The lifespan of a kettle is mainly determined by the lifespan of the temperature control device, so using a high-quality temperature control device will significantly increase the lifespan of kettle products. The products of Half-Moon use famous brand temperature control devices. If used 5 times a day, the service life of Half-Moon kettle products can exceed 6 years.
How to clean water scale?
Answer: Water scale cleaning can be done by soaking in vinegar, lemon juice, or a special scale remover, and then cleaning with clean water.
How to maintain an electric kettle?
Answer: Please note the following points: (1) Operate strictly according to the instructions for use, do not damage the cover, switches, and other parts; (2) Do not dry burn multiple times, which may damage the temperature controller and heating tube; (3) Be sure to fill the water without spills into the handle and base, which may cause electric shock and burn; (4) Clean the scale and dirt once every 2-3 months to maintain cleanliness and hygiene.
18. Should the power supply be unplugged when not in use?
Answer: Unplug the power supply when not in use to ensure safety.
19. How should a kettle be maintained if it is not used for a long time?
Answer: The power cord should be stored within the base, and the kettle should be cleaned thoroughly and well-packed before being placed in a dry place for storage.
Can kettles be used with other electrical appliances on the same socket, and what type of socket should be used generally?
Answer: It is best not to use the same outlet with other electrical appliances, as the current of the kettle is relatively large, and it is suitable to use an outlet with about 10-13A.
