The dangers of water heaters not being cleaned! Water heaters are not recommended to be cleaned

When it comes to water heaters, everyone should know that some people ask that water heaters are not recommended to be cleaned for more than 10 years, of course, some people ask that electric water heaters are generally cleaned once every few years, what is going on? In fact, it is not recommended to clean the water heater for more than 10 years, and next, I will teach you that the water heater is not recommended to be cleaned for more than 10 years, I hope it will help you! It is not recommended to clean the water heater for more than 10 years, but it is recommended to clean it.

The maintenance of electric water heaters is very important, on the one hand, to ensure the safety of electricity, and on the other hand, to see whether it can achieve the expected service life. Maintenance method: 1. Clean the inner tank regularly, because the trace impurities and minerals contained in the water will slowly precipitate down after long-term use, if cleaned, it will affect the water quality and the service life of the whole machine; 2. The user of the electric water heater regularly asks professionals to inspect the equipment every year to check the safety performance and possible potential hidden dangers to eliminate, 3. If it is idle for a long time, turn off the power supply and drain the water storage of the inner tank; 4. In order to ensure the normal use of the water heater, the safety valve needs to be maintained no less than once a month to ensure the normal pressure relief of the safety valve.

1. This will keep the water heater at high temperature for a long time, and will have a chemical reaction with stainless steel, aluminum and other substances, resulting in harmful substances, and the concentration will continue to increase. These harmful substances are easy to cause allergies and cause various diseases. 2. Waste of energy, and will continue to increase energy consumption, after a long time, the water heater will slowly occur various failures.

Relevant knowledge popularization materials: 1. Affecting the safe operation, the heating rod of the water heater will transfer heat to water or other media soon after heating during normal operation, and the temperature difference between the two is very large. If there is limescale, the heat of the heating rod will be blocked by the scale, so it will be difficult to transfer it to the water, so the temperature will rise sharply and the strength will decrease.

2. If the water circulation is destroyed if it is not cleaned, after the scale is generated in the water heater, the evaporation will be reduced due to poor heat transfer, which will reduce the pressure of the equipment. If there is fouling in the water pipe, the flow cross-sectional area will be reduced, thereby increasing the flow resistance of the water circulation, and in severe cases, the pipeline will be completely blocked, thereby destroying the water circulation, and finally in serious cases, it will cause a pipe burst accident. 3. If it is not cleaned, it will shorten the service life of the water heater.

For example, when there is a 3 mm thick scale in the inner tank, the temperature of the steel will rise from 280 degrees to 580 degrees or even higher, which will cause serious accidents.

The water heater is not recommended to be cleaned as follows:

If you don't remove it and wash it, your height is not enough, and it is difficult to clean it; If it can be removed and washed, of course, it is good, Yu Naji is afraid that it will not be installed when it is removed, there are many parts of the water heater, and the circuit requirements are high.

In addition, the steps of disassembling and cleaning the water heater are complicated, from the small screw cap to the large cold water pipe and the hot water pipe, which is the first to disassemble is particular, and it is a big head to think about.

To sum up, the electric hot water celebration device must be cleaned, ordinary cleaning once a year, large cleaning once every three years, the frequency is not high, find a professional master to clean the effect is better and safer.

The necessity of water heater cleaning:

It is necessary to clean the water heater, and the water heater cleaning and descaling should be based on the water quality in your area, under normal circumstances, it should be cleaned once every 1 to 2 years, and it is easy to have problems if the water heater is not cleaned for a long time, and there will be scale blocking the electric heating pipe and water pipe of the water heater, resulting in no water or water heater failure.

If the electric water heater is not cleaned, the hot water will produce harmful components. The harmful components produced are actually the scale formed by the condensation of calcium and magnesium ions in the water on the surface of the metal heating rod at high temperature after being decomposed by heat, that is, calcium carbonate and magnesium hydroxide.

In addition, if the tap water is not completely purified, there will be colloids, particles, rust, sediment, etc., which can be combined with small scale particles to form a thick layer of scale on the heating rod, the longer the time, the thicker the scale.

There is limescale in the water heater, which will breed bacteria on the one hand; On the one hand, scale will affect the service life of the water heater, and it will also cause ** in serious cases.

Limescale contains a variety of chemical components, and long-term precipitation and accumulation make the harmful substances in the water continue to increase, resulting in ** allergies.

In addition, the thermal conductivity of scale is very poor, and if a large amount of scale is attached to the heating rod of the electric water heater, the heating efficiency will be greatly affected. The heat of the heating rod is blocked by the scale, which is difficult to transfer to the water, so the temperature rises sharply and the strength decreases significantly.

Precautions for water heater cleaning.

When cleaning the electric water heater, you must pay attention to cutting off the power supply, and be careful of causing a vicious situation such as electric shock.

In addition, in some joints, the hot and cold water pipes should be rinsed repeatedly, and clean water flows out of them to ensure that the inner tank is clean. After cleaning, check whether there is leakage at each joint, and reconnect if there is leakage.

If it is a storage type electric water heater, it is best to clean it every 3 years, while the instantaneous type can be a little longer. The cleaning of the electric water heater in place can save more electricity and reduce the occurrence of some accidents.

1. Not cleaning the water heater will produce the following hazards:

1) Long-term exposure to high temperature will have a chemical reaction with stainless steel, aluminum and other substances, resulting in harmful substances (nitrite containing iron, aluminum, ammonium, etc., heavy metals, arsenide, etc.), and the concentration will continue to increase. These harmful substances are easy to cause allergies and cause various diseases.

2) Waste energy and increase energy consumption. It is reported that the thermal conductivity of scale is very poor, only one-tenth to one-hundredth of copper, iron and other metals, if a large amount of scale is attached to the heating rod of the electric water heater, it will greatly affect the heating efficiency.

3) Affect the safe operation. When the heating rod of the water heater is operating normally, it will transfer heat to water or other media very quickly after heating, and the temperature difference between the two is very large. When there is scale, the heat of the heating rod is difficult to transfer to the water due to the blockage of the scale, so the temperature will rise sharply and the strength will decrease significantly.

4) Disrupt the water cycle. When scale is generated in the water heater, the evaporation is reduced due to poor heat transfer, which reduces the pressure on the equipment. If there is scaling in the water pipe, the cross-sectional area of the flow will be reduced, which will increase the flow resistance of the water circulation, and in serious cases, the pipeline will be completely blocked, destroying the water circulation, and in serious cases, it will cause a pipe burst accident.

5) Not cleaning will shorten the service life of the water heater. For example, when the inner tank is 3 mm thick, the temperature of the steel will rise from 280 to 580, and the tensile strength will drop from 40 kgf mm2 to 10 kgf mm2, resulting in overheating, deformation, bulging, and even cracking of the inner tank.

2. Water heater.

A water heater is a device that turns the temperature of cold water into hot water in a certain period of time through various physical principles. According to different principles, it can be divided into electric water heaters, gas water heaters, solar water heaters, magnetic energy water heaters, air energy water heaters, heating water heaters, etc.

If the electric water heater is not cleaned for a long time, it will not be harmful to people, but there is more and more scale, resulting in slow heating, less water storage, and in serious cases, it will damage the electric heating rod (the contact surface between the electric heating rod and the water is small, resulting in poor heat dissipation).

The electric water heater is heated by a heating rod stretched out of the water (it can be understood as a fast heat). When the electric water heater is working, the temperature near the heating rod is the highest, and it is also the easiest to produce scale here - so the scale that is first produced is often wrapped in the heating electric water heater for a long time, and it will be easy to produce a lot of scale, and if it accumulates to a certain extent, it will affect the heating efficiency of the electric water heater, and serious safety hazards will occur. When the heating rod of the water heater is in normal operation, the heat will be transferred to the valve soon after heating, and the dirt is also easy to breed bacteria and mold, which is not good for human health.

When cleaning, you must turn off the power (unplug), release the hot water in the gall, remove the screw of the sewage outlet, replace the magnesium rod, clean, if there is too much rust and dirt inside, you have to remove the heating pipe and clean it all, The electric water heater can be said to be an indispensable household appliance in our winter. An electric water heater is used to heat its water.

There are three major water heaters on the market, namely electric water heaters, gas water heaters, and solar water heaters. We generally have scale and even rust on the stick, which gets thicker and thicker over time.

This will not only affect the heating speed of the electric water heater, but also affect the water quality in our electric water heater, increase energy consumption, and the most serious will also block the water pipe, causing damage to the electric water heater, and the second is the aging of the urban water supply pipeline, which will bring sediment, rust, pollutant deposition, breeding bacteria, causing clogged pores and even bringing the best disease. There will also be a particularly thick layer of scale on the heating pipe, which is covered with the heating pipe, so that the heating is not direct but indirectly heated, so it will lead to an increase in the power consumption of the water heater, the heating time will become longer, and even the heating pipe wall will be broken, so the main reason for this problem is that the traditional electric water heater needs to use the heating pipe to heat cold water in the inner tank, so in order to solve this problem, in fact, we found that it is not possible to set up the inner tank.

If the water heater is not cleaned for a long time, it may breed a lot of bacteria, but if people use the water in the water heater, it may cause some harm to people's health.

Shorten the service life. Long-term use will produce scale, and the accumulation of scale will corrode the inner tank and heating rod, shorten the service life, and in serious cases, it will also lead to leakage, which is a potential safety hazard!

Causes ** allergies.

Experts say that scale contains a variety of chemical components, and long-term precipitation and accumulation make the harmful substances in the water continue to increase, which may lead to ** allergies; Slime, microorganisms, and bacteria also form a lot of harmful substances in the continuous renewal and alternating reaction over a long period of time. It can cause the occurrence of a variety of ** diseases, and some women and children sometimes feel **itching and red spots after bathing.

If the water heater is not cleaned for a long time, it will not only form scale inside the water heater, but also breed bacteria and affect your health. Long-term failure to clean will also cause pipe blockage, no hot water and other failures. When problems occur, maintenance is not a small expense, and regular cleaning is the most reasonable.

Circulation of living water inside the water heater.

Difficult, long-term use will produce scale, the accumulation of scale will corrode the inner tank and heating rod, accelerate the aging of components, shorten the service life, seriously lead to leakage, there are potential safety hazards.

When the heating pipe is filled with limescale, it is difficult for the water heater to heat up to the set temperature because of the thermal conductivity of the scale.

Much lower than the thermal conductivity of metal. The presence of limescale will reduce or even fail the electric heat energy conversion rate, which will seriously affect the heating of water. Fouling takes up space and reduces water storage.

"Scales contain a variety of chemical components, and long-term accumulation will cause more and more harmful substances in the water heater, and bacteria will also multiply.

When bathing, these harmful substances will flow out with the water and come into contact with **, leading to various **diseases, resulting in **itching after bathing.

and rashes. After the water heater is fouled, the evaporation is reduced and the equipment pressure is reduced due to poor heat transfer. If there is fouling in the water pipes, the cross-sectional area of the water flow decreases, increasing the flow resistance of the water cycle.

In severe cases, it will completely block the pipeline, destroy the water circulation, and in severe cases, it will cause pipeline accidents. Clean the electric water heater.

, you must pay attention to cutting off the power supply to avoid causing electric shock and other malignant situations. At some joints, cold and hot water pipes should be repeatedly flushed and clean water should flow out of them to ensure that the internal tank is clean. After cleaning, check each fitting for leaks.

If there is a leak, reconnect.

The electric water heater is cleaned in place to save electricity and reduce accidents. The water heater should be cleaned in a timely manner. It is recommended that household water heaters be cleaned every three months to ensure that the heating rods are not encapsulated by limescale, not only water heaters, but also common appliances such as refrigerators, air conditioners, and washing machines need to be cleaned regularly.

It may cause the water heater**, it may also cause too much dirt in the water heater, it may cause the water heater to be scrapped, it may cause the water heater to malfunction, and it may also cause the water heater to leak, these are very serious hazards, all of which may cause harm to themselves.

It is very likely to cause electric shock, and the water is very dirty during the bathing process. The temperature is very cold. It's easy to happen**. Unhygienic and life-threatening

It may cause harm to **, may cause bacterial infection, or **allergies, and will also lead to ulcers, or cause various **diseases.

1. The water heater is in a high temperature state for a long time, which is easy to have a chemical reaction with some stainless steel furniture in the kitchen, thereby breeding harmful substances and further damaging human health. 2. Due to the long-term non-cleaning of the water heater, a layer of scale will be attached to the surface of the water heater, which will lose the heating effect of its base bend, and further lead to the consumption of its internal power. 3. Due to the non-cleaning of the water heater, the scale adheres to its surface, and in the case of heating normal water, the water volume will not reach a certain heat, thereby reducing the use intensity of the water heater.

Suggested Treatment:

First of all, turn off the main power switch of the water heater and conduct a comprehensive inspection of the water heater parts. After there is no problem, open the pressure relief valve, close the refrigeration valve, and then use a special cleaning to carry out a comprehensive cleaning of the dirt accumulation of the water heater, so that the cold water enters the valve, flushes the inside of the valve, and better cleans. Then use a special water heater detergent to carry out a comprehensive brushing process on the water heater, if possible, squeeze the detergent into the drain hole of the water heater, and after the valve of the key water heater, follow the instructions for water heater cleaning to eliminate the attack process, and wait for the water heater to be cleaned.

However, after a certain period of time, the valve can be opened and the water heater can be drained until there is no foam at all.
