What is the use of the magnesium rod inside the water heater drain

The magnesium rod inside the water heater drain is usually used to protect the water heater's blowdown system. Magnesium has a high resistance to corrosion, so placing it inside the drain can help reduce corrosion to the water heater blowdown.

The magnesium rod inside the outfall is usually made up of many small pieces of magnesium bars. The role of these small magnesium strips is to absorb the oxygen contained in the water that enters the water heater, which helps to reduce corrosion to the inside of the water heater. When the magnesium rod has absorbed enough oxygen, it becomes soft and may form a softened sediment inside the outfall.

In this case, sediment in the drain should be cleaned regularly to ensure the proper operation of the water heater.

Overall, the magnesium rod inside the water heater drain is a common preservative, which can effectively help reduce the corrosion on the inside of the water heater, thereby extending the life of the water heater.

1. To clean the magnesium rod, first take out the magnesium rod, and the step to take it out is that there is a hexagonal screw cover on the left side of the inlet and outlet pipe, and the screw out will come out with the magnesium rod. 2. Then you can use baking soda to clean the magnesium rod, or you can directly clean the magnesium rod with water. 3. If there is too much scale and it can't be cleaned, then you can choose to replace it with a new magnesium rod directly.

4. After cleaning the magnesium rod, you can add descaling agent to the inner tank, soak it for a certain time to discharge the sewage, rinse it with water several times, and put the magnesium rod back on. Relevant knowledge popularization: 1. When using the water heater for the first time, it is necessary to ensure that the installation is firm, and the setting of the water heater is completed according to the instructions to prevent improper operation from affecting the water heater.

2. In addition, it is necessary to check the water heater regularly to ensure the safety and effect of the water heater, after a period of use, the heating pipe and other parts are very easy to produce scale, so regular maintenance of the heating pipe can improve the heat efficiency of the water heater. 3. In addition, the cleaning of the inner tank is also very important, and it is recommended that the inner tank should be cleaned once every six months. 4. If you don't use the water heater for a long time, you need to turn off the power and empty the water in the water heater.

You can unscrew the screws and take a closer look, sometimes the magnesium rod will be encased in dirt or impurities in the water, there should be.

However, if you are sure that you can't find it, then you can consult with the after-sales service.

If not, you can also apply for after-sales door-to-door service. If it is determined that there are no magnesium rods, there is no need to add new magnesium rods. If you already have a magnesium rod, then you have to add a new one.

Because the magnesium rod and the sewage outlet are not together, so it is normal to find the magnesium rod, you can continue to find another outlet similar to the sewage outlet, after unscrewing it is the magnesium rod, the magnesium rod can remove part of the scale in the water, prolong the service life of the heating tube and improve the heating efficiency of the heating tube, and reduce the scale on the inner wall, so if the conditions permit, it is best to replace it with a new one, of course, you can continue to use it without magnesium rod.

The function of the magnesium rod in the water heater is to release magnesium ions during the use of the water heater and react with the calcium ions in the scale to prevent the scaling of the inner tank. When opening the sewage outlet, there should be a large amount of scale block flowing out, at this time, the water heater hand hole should be opened to clean, do not continue to use, clean the scale on the inner tank and heating rod, and then install a suitable magnesium rod to continue to close.

If you can't find the magnesium rod, maybe the appearance of the magnesium rod is not the original appearance, the magnesium rod is to neutralize the scale, and it will change the appearance of existence after the reaction; The water heater can be used normally without a magnesium rod, and if there is a lack of magnesium rods, it is better to add one.

The magnesium rod is normally installed at the seat of the water storage tank, and the hole between the magnesium rod and the sewage outlet can be found when the sewage outlet is removed. The main function of the magnesium rod is to let the stone elements in the water absorb on the magnesium rod, so as to change the cleanliness of the water quality, make the heater last longer, and the human body will be more comfortable. If you don't find a magnesium rod, you can buy a magnesium rod according to the size of the water storage tank and the brand of the electrical appliance, so that the service life of the water heater can be more guaranteed.

If the magnesium rod is not used, it will also have an iron compass, if the compass is not, it means that it is not installed, and it can be used normally. If it's convenient, it's best to put one, and its function is to neutralize scale.

Some of the magnesium rods of storage electric water heaters are installed separately and are not together with the sewage outlet.

The function of the magnesium rod is to soften and absorb the impurities in the water to avoid the generation of scale, for the storage water heater, the magnesium rod has the benefit of prolonging the service life of the water heater.

Therefore, it can be used without magnesium rod water heater, but the heating rod will produce scale, which will affect the service life of the water heater.

It may be that the magnesium rod has already reacted, and the magnesium rod generally starts to be replaced in about three months, and you may not have replaced it for a long time in this case.

It is best to put in the magnesium rod to reduce the scale, and protect the heating rod and the barrel have a certain effect.

Magnesium rods. In the water heater, it is used to slow down the corrosion rate of the inner tank of the water heater, and it is also possible to use it, and most storage electric water heaters are provided with magnesium rods to prolong the service life of the water heater.

The main ingredient of the magnesium rod is magnesium, and in the inner tank of the water heater, it and the inner tank (the main ingredient is iron) are in contact with water at the same time, and the galvanic battery is formed due to the chemical principle. Since the water in the inner tank is not pure water, it always contains a variety of impurities and has a certain corrosiveness, and when the water temperature exceeds 40 degrees, scale will be generated. If there is no anode magnesium rod, the inner tank is corroded.

The principle of anti-corrosion. In the use of too steel type or manganese steel.

Metal liners, which utilize the electrochemistry of metals in water.

Anti-corrosion sacrificial anode protection cathode principle, magnesium rod as anode, metal liner as 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.

In a water heater, the magnesium rod is installed in the middle of the metal liner. Enamel on the surface of the metal liner.

When the coating is intact, the enamel shields the metal liner and insulates the resistance between the magnesium rod and the metal liner.

It can reach more than 2m, and the output current of the magnesium (rod) anode is almost zero.

However, when there is a local crack in the enamel liner, a small resistance is formed between the magnesium anode and the metal liner through water, and the magnesium anode begins to output current, which flows to the exposed metal liner to produce a polarized film, repair the damaged enamel, and insulate the gold liner to prevent corrosion.

Magnesium rods are mainly used to remove limescale! If you don't use it, it's easy to get stuck with limescale!

The magnesium rod is a reactive metal, and the corrosive impurities in the reclaimed water first react with it, so as to protect the inner tank and heating pipe of the water heater.

Water heater, magnesium rod plays a great role, experts help you interpret.

How to replace the magnesium rod of the electric water heater, and how much? Today is a long time to see.

The sewage outlet of some water heaters is in the plastic base under the water tank, which can only be seen by removing the plastic base; The location of the magnesium rod near the heating pipe on the side of the water heater.

This kind of sewage outlet is designed inside the control panel, and the design of the control panel can not be removed, it will be more troublesome when replacing the magnesium rod, and the hot water must be emptied before replacement, otherwise it will be scalded by hot water when the sewage outlet is unscrewed.

An electric water heater refers to a water heater that uses electricity as an energy source for heating. It is one of the three major water heaters alongside gas water heaters and solar water heaters. Electric water heaters can be divided into three types: water storage type (also known as volumetric type or heat storage type), instant heating type, and rapid heat type (also known as semi-water storage type) according to the heating power.

According to the installation method, the water storage type can be divided into wall-mounted (horizontal) electric water heater and floor-mounted (vertical) water heater, the volume of wall-mounted electric water heater is usually 40L-100L, and the volume of floor-mounted water heater is usually more than 100L.

Household storage electric water heaters have the characteristics of easy installation, large water output, and stable water temperature, but the traditional storage electric water heater has a slow heating speed and a long waiting time.

Instantaneous instantaneous electric water heaters (also known as fast-heating electric water heaters in the industry) generally require a current of more than 20 or even 30 amperes. Internal low-pressure treatment, can be installed at the time of installation, higher power products are installed in the bathroom, can be used for showering, can also be used for washing, general household use energy saving and environmental protection.

Rapid heating type electric water heater is an independent category of electric water heater products that are different from storage type and instantaneous type, between storage type and instantaneous type or a combination of the two, using rapid heating engine heating technology, making it possible to produce hot water more quickly with low-power heating (relative to instantaneous power).

Judging from the **, this water heater does not have a special sewage outlet.

However, whether this water heater has a special sewage outlet has nothing to do with the magnesium rod.

If you are sure that this storage electric water heater is equipped with magnesium rods, you can open the outer cover plate of the electronic control parts on the side of the water heater to see if there is an end of the magnesium rod displayed inside. If you can find the end of the magnesium rod here, it is where the rod is mounted.

There are also some storage electric water heaters that are not designed to install magnesium rods when they are designed.

First of all, check the instruction manual of the water heater, or contact the after-sales service for consultation to determine whether there is a drain nut.

Some water heaters have a blowdown nut in the plastic base under the tank, which can only be seen when the plastic base is removed.

Storage electric water heaters should be cleaned regularly according to the local water quality and the amount of water used. When the water from the sprinkler head is large and small, cold and hot, accompanied by similar air flow sound, it means that there is too much scale in the water tank, and the scale needs to be cleaned in time. The specific cleanup method is as follows:

If there is a drain nut under the water heater tank, cleaning is very simple, and the water in the tank can be drained by unscrewing the nut. When the water is almost empty, the scale at the bottom of the tank will be brought out. After draining the water, temporarily screw the nut on, then add a little water to the tank before releasing it.

Repeat this several times, after the water is thoroughly cleaned, it means that the scale is cleaned up, tighten the nut to add water to the water tank, and then use it after the water is full.

If the water heater does not have a special sewage nut, it is necessary to remove the water pipe on the right side, and then remove the safety valve, so that the water can be discharged, and after the water is finished, 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, and finally the safety valve and water pipe can be reinstalled and reset to add water to the water tank, and the water can be used when the water is full.

If it is in the north or the Central Plains, due to the hard local water quality, it is easy to produce scale, so the magnesium rod should be replaced regularly to reduce the production of scale, in addition, it should also be noted that it is best to adjust the water temperature reasonably according to the seasonal ambient temperature, the higher the water temperature, the easier it is to produce scale, so try to lower the water tank water temperature, especially in summer. In many areas along the southern coast, there is no need to replace the magnesium rod because the tap water quality is softer and will not produce scale, but the dirt in the water tank should also be cleaned regularly.

Storage electric water heater, usually the power is about 1500W, it is best to replace the power socket of the water heater with a 16A switch, and control the opening and closing of the water heater power supply through the switch, so as to avoid frequent plugging and unplugging of the power plug is prone to poor plug and socket contact and resulting in heat and ablation failure. How to save electricity in a storage electric water heater depends on the frequency of use. If the frequency of use is high and hot water is often needed, it should always be kept on the state, which is both convenient and relatively energy-saving; However, if the frequency of use is low, and you only occasionally use hot water for bathing, you should use electricity to heat it before use, which is also more energy-saving.

Especially in summer, it is generally heated for about 15 minutes to meet the temperature requirements of the bath, so the operation is very energy-saving. With the function of temperature regulation, the water temperature should also be reasonably set according to the seasonal ambient temperature and the amount of water used, and the water temperature can be adjusted at about 40 degrees in summer, so that it is more energy-saving. But in winter, if you are in the north, because the ambient temperature is low, you must heat the water to the highest temperature, otherwise the hot water will not be enough.

Like my house, on the left side of the cylinder, remove the disc with the heating tube in the middle, and you can see the magnesium rod. If your home has been used for more than 8 years, it is recommended that you do not replace the magnesium rod, but directly replace it with a new one, and choose the sewage outlet below next time.

Take out the electric heating pipe on the side and you can see it.
