First, the water temperature of the water heater must be adjusted to the highest (75 degrees) to ensure the hot water supply time.
The second is to reduce the water output as much as possible and extend the use time of hot water.
The third is to raise the temperature of the bathroom as much as possible. An electric heater with warm air can be installed at the top of the bathroom. If the temperature is not high enough, you can also place an electric heater under or on the side of the bathroom, which can effectively improve the temperature of the bathroom and make people not feel cold. When taking a bath, the water temperature can be appropriately reduced to avoid cold, so that the hot water service time of the water heater will be extended.
In addition, if you are updating the water heater, you can buy a water heater with larger capacity and greater power, so that hot water is enough in winter.
Common sense of using water storage electric water heater;
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.
Usually, the power of the water storage electric water heater is about1500-2500 w-2500 w. It is better to replace the power socket of the water heater with a switch socket of 16A, and control the power of the water heater through the switch to avoid frequent plugging and unplugging of the power plug, resulting in poor contact and thermal ablation. If the power of the water heater is above 3000 watts, and the manufacturer does not have a power plug and socket, a high-power leakage switch can be installed for online use.
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 far left below the water tank of the water heater, it is very simple to clean. Unscrew the nut, pull out the magnesium rod inside and drain the water in the water tank. When the water is almost used up, the scale stains deposited on the bottom of the water tank will be brought out. After draining, temporarily screw on the drain nut, then temporarily connect the water pipe to the hot water pipe joint, add some water to the water tank, let the tap water spray in the water tank to wash the whole inner cylinder, and then drain. Repeat it several times. After the discharged water is thoroughly cleaned, it means that the scale is cleaned. Insert the magnesium rod, tighten the drain nut and add water to the water tank. When the water is full, it can be used by heating with electricity.
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 the magnesium rod depends on the corrosion and dissolution of the magnesium rod. At present, most manufacturers use long-acting magnesium rods, which are very durable and basically synchronized with the service life of water heaters, and there is no need to improve the magnesium rods. 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, and usually adjust the water temperature to about 40 degrees. 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.
