Is it useful to add magnesium rods to solar water heaters? Or is it a drop in the bucket?

The magnesium rod in the water heater is to prevent scale formation in the water heater, and the water will produce scale in the case of high temperature, which is calcium carbonate chemically speaking, and the magnesium of the magnesium rod can effectively neutralize and dilute the calcium carbonate, thereby prolonging the service life of the water heater.

Answer: If the magnesium rod fails to work, replace it in time, otherwise the water heater will leak and break soon.

Adding magnesium rods to solar water heaters has a certain effect, but it does not completely solve all problems. Here are its main roles:

1.Prevent scale: Magnesium rods can absorb calcium, magnesium and other ions in the water, reduce the formation of scale, and thus prolong the service life of solar water heaters.

2.Prevent corrosion: The metal material inside the solar water heater is susceptible to corrosion, while the magnesium rod can absorb oxygen and other harmful substances in the water to prevent the metal material from being corroded by corrosion.

3.Improve water quality: Since magnesium rods can adsorb some harmful substances, they can improve the water quality in solar water heaters.

But it should be noted that adding magnesium rods does not completely solve all the problems. If there is already a serious scale or corrosion problem inside the solar water heater, it may not be completely solved by adding magnesium rods alone. In addition, different solar water heater brands and models have different needs for magnesium alarm sticks, please carefully understand the relevant information before purchasing.

Harmless. The function of placing magnesium rods in the water heater is to adsorb ions in the water heater and protect the inner tank and heating pipe of the water heater. In a water heater, the magnesium rod is installed in the middle of the metal liner.

When the enamel coating on the surface of the metal liner is intact, the enamel shields the metal liner, and the insulation resistance between the magnesium rod and the metal liner can reach more than 2m, and the output current of the magnesium (rod) anode is almost zero.

When there is a 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 to repair the damaged enamel and insulate the Jinyu liner to prevent corrosion.

<> function: protect the inner tank from corrosion, prolong the service life of the water heater water heater. In water heaters, magnesium rods are used as anodes

Magnesium, which is more chemically active, first combines with carbonate ions and bicarbonate ions in water to produce magnesium carbonate (scale). Magnesium consumes all the negative ions in the water, and the iron (inner tank) is safe.

Tap water is very easy to produce scale after heating, scale has a certain corrosive ability, over time, it will corrode the inner tank, resulting in water heater leakage. Today's water heater liners are generally protected by enamel technology, but there is still no guarantee that the plating will not crack - once the enamel layer cracks, the leaking metal part will be corroded.

In the face of this metal that is susceptible to corrosion, people often use "sacrificial anode" technology to protect the metal - a chemical protection method similar to the principle of galvanic batteries, where the reactive metal is the first to corrode, thus avoiding the inactive metal from being harmed.

In the process of consuming negative ions in the water, magnesium ions are also consumed – so magnesium rods are consumables that need to be replaced every once in a while (the length of time is related to the quality of the water).

The function of the magnesium rod is to insulate the inner tank and prevent corrosion.

In the inner tank of the water heater, it and the inner tank (the main component is iron) are in contact with water at the same time, and the galvanic battery is formed due to the chemical principle.

Because the water in the inner tank is not pure water, it always contains a variety of impurities and has a certain corrosiveness, when the water temperature exceeds 40, it will produce scale. If there is no anode magnesium rod, the inner tank is corroded.

Caution for use: It is best to use softened tap water. The hardness of the water quality is clear as long as it depends on whether the scale is often scaled when boiling water in your home (the scale is mostly a mixture of calcium and magnesium), and the water that is prone to scale should not be used directly in the water heater (which is more important for gas water heaters).

The high hardness of water will cause a thick coating to form around the electric heater, which will reduce the heating efficiency and endanger the life of the electric heater itself due to the slowing down of heat transfer. In addition, the scaling layer of the outlet pipe mouth continues to thicken, which will reduce the diameter of the pipe or even clog, causing the water heater to malfunction.

The magnesium rod of the water heater is not universal, and the magnesium rod of different brands of water heaters has differences in size and installation, so it is recommended to contact the after-sales service to find out what model of magnesium rod needs to be used for the water heater purchased.

The function of the magnesium rod is to prevent the inside of the water heater from being corroded, which can prolong the service life of the water heater, with the growth of the use time, the magnesium rod will be lost, the stronger the conductivity of the water, the faster the magnesium rod will be lost, it is recommended to maintain the water heater regularly and replace the magnesium rod.

Precautions for the use of water heaters: 1. The water heater cannot work, which is generally the loss of heating components, and it is recommended to ask professionals to deal with it.

2. The water heater should be installed firmly, if the screws are loose, it is recommended to ask professionals to maintain them.

3. If there is any abnormality in the operation process of the water heater, it should be stopped, and it is recommended to ask a professional to overhaul it.

4. The water heater cannot display the temperature, it may be that the display screen is damaged, and it is recommended to replace the display screen.

Data expansion: The air source heat pump water heater is regenerative type, and the heating function is automatically started according to the temperature in the water tank to ensure that the hot water is sufficient for 24 hours**, so there will be no problem that the hot water cannot meet the needs of multiple faucets at the same time like a gas water heater, and there will be no problem that the electric water heater has a small capacity and many people need to wait for a bath. Ready-to-use hot water, large water output, stable water temperature.

Magnesium rod, also known as anode rod, is mainly composed of magnesium, which is a consumable, and its main role in the inner tank of the water heater can play a role in protecting the inner draft section of the tank and slowing down its corrosion.

Characteristics of magnesium ions (Mg2+): Both iron and magnesium can be soluble in water, but magnesium is more electropositive than iron and is more likely to become magnesium ions (Mg2+).

Magnesium anode rod. The reason why magnesium rods work to slow down corrosion is that magnesium is more reactive than iron, so magnesium dissolves in water first. The magnesium is separated from the magnesium rod and combined with oxygen, and the corrosion process ends. In other words, the magnesium rod is corroded and the inner liner is intact.
