Electric heaters generally use heat-resistant plastics, alloys and other materials. Looking at the thickness of the material from the side, the products with large thickness generally have better heat resistance and extrusion resistance. At the same time, the workmanship of the electric heater can also be seen by observing whether the welding at the interface is smooth, whether there are sliding marks on the surface and whether the paint is uniform. Be sure to choose products with good workmanship when buying. The power of the electric heater is relatively high, but the higher the better, the greater the power and the greater the power consumption. General 1000 watt products can meet the use needs of rooms around 10 square meter. When buying, you should consult the sales staff in detail and determine the power reasonably according to your own use. Power-on test When selecting products, be sure to power-on test, personally experience whether the temperature rises rapidly, carefully observe whether there is electric spark, and turn the thermostat to see whether the temperature changes obviously and whether the shell becomes soft and deformed. After testing, buy. Buying electric heaters depends on after-sales service, carefully read and fill in the product after-sales service card, and understand the product warranty and return regulations, so that problems can be solved by the after-sales service department as soon as possible. Use electricity protection: while people enjoy electric heaters to keep warm, safety is also very important. The reporter consulted the technical personnel of the manufacturer on how to use the electric heater safely, hoping to provide some reference for your use. First, configure the socket reasonably. The working power of electric heaters is relatively large, generally above 1000 watts, and the current is relatively large, so the requirements for power sockets are also relatively high. It is best to choose a socket whose rated power and current meet the product manual and overcurrent protection, and it is best not to use one socket for multiple appliances. Second, pay attention to the position. When using, pay attention to stay away from the humid environment such as bathtub and faucet, and the position of power socket should also avoid being splashed or sprayed by water, otherwise it will lead to short circuit and burn out the electric heater. Third, don't use the top gear for a long time. When the electric heater is working, the thermostat should not always be set at the highest gear. Long-term high-temperature operation is easy to burn out internal equipment or damage protective components. Finally, it is forbidden to cover the electric heater. In use, people often use electric heaters to bake clothes, and directly cover them, which will lead to an increase in the internal temperature of the electric heaters.
