The water storage electric water heater should regularly clean the water tank scale according to the local water quality and water consumption. When the water sprayed by the nozzle is big and small, cold and hot, accompanied by similar air flow sound, it means that there is too much scale in the water tank and it needs to be cleaned in time. The specific cleaning method is as follows:
If there is a drain nut on the left side under the water tank of the water heater, cleaning is very simple. You can unscrew the nut and drain the water in the tank. When the water is almost used up, the scale at the bottom of the water tank will be taken out. After draining, temporarily screw on the nut, then add some water to the water tank before draining. Repeat it several times. After the discharged water is thoroughly cleaned, it means that the scale is cleaned. Tighten the nut and add water to the water tank. When the water is full, it can be used by electrifying and heating.
Some water heaters have a plastic base under the water tank, and the drain nut on the left side needs to be removed.
If the water heater does not have a special drain nut, you must first remove the water pipe on the right side, and then remove the safety valve, so as to drain water. After the water is released, temporarily connect the water pipe to add some water to the water tank and then release it, so that the scale in the water tank can be removed several times. Finally, the safety valve and water pipe can be reinstalled to add water to the water tank, and the water can be electrified for use.
Whether to replace magnesium rods regularly depends on the geographical location of users. If it is in the north or the Central Plains, because the local water quality is hard, it is easy to produce scale, so it should be replaced regularly to reduce scale. In addition, it should be noted that it is best to adjust the water temperature reasonably according to the seasonal environmental temperature. The higher the water temperature, the easier it is to produce scale, so try to reduce the water temperature of the water tank, especially in summer. In many areas along the southern coast, tap water is soft and will not produce scale, so there is no need to replace the magnesium rod, but the dirt in the water tank should be cleaned regularly.
Usually, the power of storage electric water heater is about1500 w. It is better to replace the power socket of the water heater with a socket with a 16A switch, which controls the power of the water heater to avoid the failure of poor contact between the plug and the socket caused by frequent plugging and unplugging of the power plug.
How to save electricity depends on the frequency of use. If the frequency of use is high and hot water is often needed, it is convenient and relatively energy-saving. However, if the frequency of use is low, only hot water is occasionally used for bathing, and electricity should be used for heating before use, which also saves electricity. Especially in summer, heating with electricity 15 minutes can meet the water temperature requirements for bathing, so it is very energy-saving to operate. With temperature adjustment function, the water temperature should be set reasonably according to the seasonal environmental temperature and water consumption. It is enough to adjust the water temperature at about 40 degrees in summer, which will save electricity. But if it is winter in the north, because the ambient temperature is low, the water temperature must be heated to the highest, otherwise the hot water will not be enough.
