What are the functions of the magnesium rod of the water heater? How often should I check it?

Indirectly, the heating pipe is damaged or the inner tank is easy to leak, so the heating speed of the water heater will be slowed down, and the power consumption of the water heater will be increased. In fact, the method of replacing the magnesium rod is also very simple. When the electric water heater is energized, the heating tube heats up, the temperature of the water in the tank rises, and when the temperature reaches the preset value (detected by the thermostat), the heating tube will stop heating.

Therefore, the core of the electric water heater is nothing more than three:Heating tubes, liners, magnesium rods. Most people may not be able to see or hear, but in fact, almost all water heaters have magnets.

Some say it prevents dirt, some say it prevents water leakage. But that's not the case. His real role is to protect the gallbladder inside the water heater.

<> it reacts with the ions in the water by itself to prevent the water alkali and scale from adhering to the inner tank of the water heater and causing the inner tank to be corroded, but because it is a consumable, it needs to be replaced regularly. I think the replacement cycle of the magnesium rod of the water heater is determined according to the size of the water heater and the user's water consumption, in my experience, the average family is about 1-3 years to replace. The way to replace it is also very simple, but it is important to note that cleaning is not missing.

There are two key components of a storage type electric water heater, one is the heating rod and the other is the inner tank. Because there will be various impurities in domestic water, it will corrode the heating rod or inner tank over time, and the use of magnesium rod is to protect the heating rod and inner tank.

When the water heater is added with electricity, the current will pass through the tubular electric heating element, which will convert the electrical energy into heat energy, and then after the contact between the water heater wall and the water, the heat will be transferred to the water that needs to be heated to provide us with bathing. Generally speaking, the magnesium rod in the electric water heater needs to be replaced every 2 to 3 years, and when it is replaced, it is recommended to clean the electric water heater. Replacing the magnesium rod of the water heater needs to be carried out by professionals, it is recommended to call the after-sales service of the water heater brand**, some brands need to be charged, and some can be replaced free of charge during the warranty period.

The function of the magnesium rod is to react with the ions in the water to prevent the water alkali and scale from adhering to the inner tank of the water heater and causing the inner tank to be corroded. Therefore, as much as possible, the magnesium rod should be replaced before it is consumed.

The service life of the magnesium rod of the water heater is generally 2 to 3 years. After about 2 years of normal use of the water heater, the user can contact the after-sales department of the water heater brand to apply for a replacement of the magnesium rod.

The function of the magnesium rod is to release magnesium ions, soften the water quality, reduce the scale, and slow down the corrosion of the metal liner by the scale. Magnesium rods are consumed very slowly, and they can generally be replaced once a year.

It mainly plays the role of protecting the inner tankIt prevents the inner tank from being corroded during operation, effectively avoids the erosion of scale and acid-sensitive alkali substances in the water quality, and makes the electric water heater safer to use. At the same time, it is also called anode rod, which uses chemical principles to form a galvanic battery with magnesium rod, water and inner tank to play an insulating effect.

The reason why magnesium rods are installed inside the electric water heater is mainly because of the water quality problem, and the water used will have some impurities and even corrosiveness. If there is no magnesium rod, then when the water temperature reaches more than 40 degrees, it is easy to produce scale, and it will accumulate more and more over time, which will affect the heating effect of the water heater.

Precautions for electric water heaters

1. When using the electric water heater, if there is no water after the water valve is opened, the power supply needs to be cut off immediately to avoid the electric water heater from entering the empty burning state and being damaged. At the same time, it is also necessary to pay attention to the problem of water inlet, which should not be too small, because it is easy to affect the use effect, and once the temperature is too high, the electric water heater will be burned out.

2. If the electric water heater is a water storage type, it must be filled with cold water when it is used, and then use it when it is connected to the power supply, otherwise the water heater will be damaged.

3. For electric water heaters, it is also necessary to pay attention to prevent being scalded when using, that is to say, it is recommended to open the cold water valve first, and then open the hot water valve. Then, after use, it needs to be reversed, which can effectively extend its service life. In addition, if the water pressure in the home is low, it is necessary to stop using it.

To judge whether the magnesium rod of the electric water heater should be replaced, the first is to look at the efficiency of the water heater, the second is to look at the water quality, and the third is to look at the use time. The worse the water quality, the faster the magnesium rod is consumed, and the magnesium rod should be replaced once every six months.

The more frequently the electric water heater is used, the faster the magnesium rod is consumed. For areas with better water quality, the magnesium rod is replaced once a year. Judging from the phenomenon, if the water flow is often turbid, or the water released by the collapse has sediment, it means that the magnesium rod should be replaced.

The utilization time of magnesium rods in water heaters is usually two to three years.

The role of the magnesium rod of the electric water heater.

The magnesium rod of the electric water heater is like an iron rod when it is consumed, and it has no effect when placed in the water heater. In daily life, the heating rod of the electric water heater heats the hot water repeatedly, it will produce water alkali, and the heating rod will be wrapped in a long time, which greatly affects the heating speed of the water heater. The corrosion speed of magnesium rod depends on what material the inner tank is, generally speaking, the stainless steel inner tank corrodes faster than the enamel inner liner.

The magnesium rod in the water heater will be consumed over time.

The function of the magnesium rod is to replace the inner tank of the water heater to accept corrosion, so it will be consumed.

The corroded part of the magnesium rod will expand greatly in volume, and the outer envelope will affect its continued function. Therefore, it should be replaced every two or three years according to the water quality and the temperature of use (the higher the temperature, the faster the magnesium rod will be consumed).

The usual service life of the magnesium rod of the water heater is 2 to 3 years, and under normal circumstances, it can be replaced every two years.

When changing the magnesium rod of the water heater, you can contact the after-sales department of the water heater brand to apply for the magnesium rod of the water heater. Be sure to replace the magnesium rod before it is exhausted. Because the consumption rate of magnesium rods in water heaters is related to environmental water quality, the worse the water quality, the faster the consumption rate of magnesium rods, and the quality of magnesium rods in water heaters must be checked regularly to confirm whether they are replaced.

Water heater magnesium rod function:

1. Prevent the inner tank of the water heater from being corroded. Because after the water in the inner tank of the water heater is heated, scale will be generated, and the scale is generally corrosive, and after a long time, it will cause corrosion to the inner tank of the water heater, resulting in water leakage in the inner tank, and after putting the magnesium rod in the inner tank.

The magnesium rod will release magnesium ions, which will slow down the water alkali and scale in the inner tank of the water heater, effectively prevent a large amount of scale from adhering to the inner wall of the inner tank, avoid corrosion of the inner tank, and reduce the service life of the inner tank.

2. Soften the scale and protect the heating rod. The magnesium rod will have a chemical reaction with the scale, so that the scale caused by heating cannot be wrapped on the heating rod into a hard lump, so as to avoid the service life of the heating rod being reduced.
