Heating element for boiling water is very common . So, what should be noted when boiling water with an electric heating tube? How can the service life of the heater element be prolonged?
There are two points to note
1.The heating area of the electric heating element must not be detached from the water surface to avoid dry burning.
2. The heated water should not be too hard and the speed of scale formation should not be too fast.
Reason
1.If the heating area is separated from the water surface, the surface temperature of the heating tube cannot be absorbed by water in time. Then the surface temperature will be very high. When the surface temperature is very high, the internal temperature will inevitably rise as well. When the internal temperature reaches a certain level, the resistance wire will be burned out, then it will be broken.
2. When the water quality is poor, hard or contains many impurities, it is very easy for scale to form. The chemical name of scale is calcium carbonate, and it has a certain corrosive effect. Over time, the protective sleeve of the heating tube will be corroded, and small holes will appear on the surface of the protective sleeve. In mild cases, there will be leakage of electricity; in severe cases, the tube may burst. At the same time, scale will also prevent the surface temperature from being absorbed by water, which will lead to the same consequence as the first one.
Therefore, corrosion-resistant materials should be selected. Only in this way can the electric heater for boiling water be used for a longer time.
