How long is the magnesium rod of an electric water heater? Do I need to clean it on a regular basis?

The service life of the magnesium rod of the water heater is generally 2 to 3 years.

Usually you can clean it like this, the hot and cold water pipes are reversed, fill the water from the hot water outlet above, and release water from the cold water inlet below, and the dirty things will be washed out.

3-5 years for families will do. The magnesium rod of the electric water heater needs to be replaced, and the regular replacement of the magnesium rod can prolong the service life of the electric water heater.

The general life span can be about 10 years, and it usually does not need to be cleaned, as long as the scale in the water heater is cleaned regularly.

The general life span is 2 to 3 years, and it also needs to be cleaned regularly, which is also for better bathing without accidents and eliminating hidden dangers.

Generally, it is more than 6 years, and the quality is also very good, and it is usually necessary to pay attention to cleaning, and it is also necessary to protect safety anytime and anywhere.

About three years, generally at this time it needs to be replaced, it needs to be cleaned, and it can be washed once every six months.

The service life is generally 8 years, but it can be cleaned after one year of use. In this way, the life expectancy can be longer and longer.

The magnesium rod needs to be cleaned and replaced. If the electric water heater is used for a long time, if the user does not clean the inner tank of the water heater in time, it will cause serious scaling of the heating pipe, the heat heating of the electric heating pipe is not sufficient, and the hot water will heat up very slowly, which affects the normal use, and there is an accident of rupture due to uneven local heating from time to time, so the electric water heater should be maintained once a year.

Magnesium rods are used in the inner tank of electric water heaters to prevent the metal inner tank from corroding and soften the water quality. In the use of Taigang or manganese steel metal liner, the electrochemical anti-corrosion sacrifice anode of metal in water is used to protect the cathode, the magnesium rod is used as the anode, and the metal liner is used as the cathode. In this way, a galvanic cell is formed through a conductive aqueous medium between the cathode and anode.

The anode of the battery, the magnesium rod, is consumed by corrosion, while the cathode, the inner metal conductor, is protected.

It is necessary to replace the magnesium rod regularly, and the regular replacement of the magnesium rod can prolong the service life of the electric water heater, and if the magnesium rod is not replaced in time after consumption, the water quality will corrode the inner wall of the water heater, which is easy to leak water and electricity, resulting in the scrapping of the water heater.

Generally speaking, the magnesium rod of the electric water heater needs to be replaced once in about 2-3 years, and the magnesium rod of some low-quality electric water heaters will be exhausted in less than half a year.

Definitely going to be replaced. Generally, it needs to be replaced once a year in order to prolong the life of the electric water heater.

First of all, we should understand the role of magnesium rods in electric water heaters. The function of the magnesium rod is mainly to protect the heating pipe and inner tank in the water heater. Therefore, we should regularly replace the new magnesium rods in our electric water heaters.

In general, magnesium rods should be replaced once a year. If it is not replaced, if it is used for too long, the surface of the heating pipe will be covered with a large amount of scale, which will indirectly cause damage to the heating pipe or the inner tank is easy to leak. In this way, the heating rate of the water heater will slow down, increasing the power consumption of the water heater.

In fact, the method of replacing the magnesium rod is also very simple. Let's see.

The magnesium rod discharges sewage at the bottom of the water heater. We just need to find a wrench. It is best to move the wrench and then unscrew the screws.

Note before twisting: Unplug the water heater power cord first, safety first, and then close the inlet valve. At this point, we can use a wrench to open the sewage outlet.

After unscrewing, there will be a large amount of dirt coming out of the tank, and then continue to unscrew. We can take out a stick directly, and it is a magnesium stick. After removing the magnesium rod, we should remove the original magnesium rod from the fixed column.

Some water heaters melt the surface of the magnesium rod after a long time, and only one rod remains. Just remove the pole. The screws are also fixed on it, and then replaced with a new magnesium rod and tightened in the original position.

After tightening, we should open the water inlet and turn the switch of the water outlet to the hot water position, so that the water heater will not come out of the water. In this way, we can expel the air. After exhausting, we can plug in the water heater until the hot water outlet is full.

Otherwise, we have to plug in the water heater. Finally, observe the location of the magnesium rod for water leakage. If there is no water leakage, it is installed.

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.
