Water heaters on the market are roughly divided into three categories according to heating methods; One: electric heating. Two: gas heating. Three: solar heating.
Electricity can be divided into storage type (that is, vat type) and instant heating type.
Water storage can be divided into quick heating and water storage. The heating method is to insert it into water for rapid heating (the heater is internal resistance wire).
Instant heating has three heating methods:
One: metal heating cup heating, like storage water heaters, whether it is copper or stainless steel, its internal heating is mainly based on electric heating wires, which are directly inserted into the water to heat the water quickly.
Two: non-metallic glass tube heating. The heating method is external heating (in the form of high-temperature sintering, normal-temperature spraying or printing, a layer of heating material, that is, a resistive film, is attached to the outer wall of a nonmetallic pipe made of nonmetallic materials).
Three: flat heating is also called bare wire heating. The heating wire is used to heat the insulating layer, and the insulating layer is used to heat the container containing water.
Based on the heating principle of all electric water heaters at present, there are many hidden dangers and disadvantages.
These hidden dangers and disadvantages are insurmountable by many enterprises in the industry at present.
2 What are the hidden dangers and disadvantages of traditional water heaters? 1: Not safe. There is no absolute separation between water and electricity, but it is directly inserted into water to heat the table. The higher the heat load on the heater surface, the higher the critical point safety value, which will aggravate the condensation speed of scale. When the scale covers the heating element, the heat energy can't be transferred to the water normally, the heating element can't be cooled naturally, and the heating time is long, which will not only consume electricity, but also aggravate the deformation and burst of the heating element. When the heating tube is red at high temperature, it will lead to the drying of the heating wire, easy to fuse and burst, and direct contact with water will lead to the danger of electric leakage. The heating pipe guided by glass film can solve the anti-corrosion function well and the insulation is acceptable. However, manufacturers choose glass fiber reinforced plastic with low hardness and weak thermal conductivity, which will burst under the condition of large temperature difference between north and south and thermal expansion and contraction, leading to water leakage. Moreover, the heating film will age quickly, and the power will drop by more than 20% every year. Resistance film is not energy-saving, resistance film falls off, consumes electricity, and heat and cold exchange is easy to blow up the tube. The biggest hidden danger is that the two ends of the glass film heating pipe leak water, especially the hard connection part, which will lead to leakage (because silica gel will age when heated). Resulting in high power consumption and potential safety hazards. 2. No energy saving, slow heat conduction, (resistance wire heating itself does not save energy, the longer it is used, the more energy it will consume, and the high accumulated temperature is easy to fuse and fall off. )。
3: Scale is the natural enemy of water heater! Is the water heater safe? First of all, ask if there is scale. A water heater with scale is by no means a safe water heater! Scale is the natural enemy of water heaters. Nine of the ten accidents were due to the fact that the heater could not absorb heat and use water to cool down at high temperature, which led to the long-term dry-burning operation of the heater and the failure of the heating wire. The heating element sheath is deformed and cracked, and the heating wire is exposed. 220V current directly contacts water, causing leakage casualties! Many old manufacturers think that installing leakage-proof walls or leakage-proof protection devices can solve the water leakage problem of water heaters, which is a lucky and irresponsible design psychology! Facts have proved that most water heaters causing leakage accidents are almost equipped with "anti-leakage walls" or "anti-leakage protection devices". Since it is prevention, it is passive, which will lead to accidents, and life is not allowed and impossible to prevent.
4: Short service life. The life of electric heating wire is very short, and it will fuse if it is used for a long time without heat conduction. If the scale is too large, it will explode. The metal heating cup itself is a small inner container, and the total length of the high-power heating tube is very limited. The shorter the heating distance, the higher the heat load on the surface of the heating element, the higher the power per square centimeter of the surface, which is easy to age with the passage of time, and it is easy to fuse and burst the heating tube when it breaks down under a large current, and the electric heating wire is in direct contact with water, which is in danger of leakage. Because magnesium and other elements in the magnesium rod will be decomposed and consumed in water with the use of the water heater, the insiders pointed out that in order to avoid accidents such as electric leakage, electric leakage of heating elements and liners, the magnesium rod in the electric water heater should be replaced every 3-6 months. If the magnesium rod water heater is not replaced for more than one year, the heating element and the inner container may have been seriously corroded, even corroded and infiltrated, leading to electric leakage and water leakage accidents. Ordinary water heaters without replacing magnesium rods may leak electricity: a leaking water heater, after being disassembled, is almost filled with large scales, metal residues, rusty water and sediments, and most heating elements are corroded and worn. The condensed scale prevents the heating element from being taken out, so it must be hammered. Leakage heating elements are mostly damaged by scale, and obvious cracks appear in the metal sheath of heating elements, and the electric heating wire is in direct contact with water, which directly leads to leakage.
5: unhealthy. In order to soften the water quality and reduce the formation of scale, ordinary water heaters. You will use an anode magnesium rod. Anode magnesium rod is the "melamine limb" of water heater. Anode magnesium rod is composed of magnesium, aluminum, zinc, zirconium and other metal elements, which will be decomposed and consumed in water during use, causing pollution. Excessive metal elements in water may cause allergic dermatitis or eczema, itching, black and white spots, hair loss and so on. In severe cases, metal poisoning may occur, leading to dizziness, fatigue, vomiting, diarrhea and even life-threatening. Excessive aluminum in magnesium bars is a health killer: excessive aluminum in food will do harm to human body. After ingesting aluminum, only a small amount of aluminum can be excreted, and most of it will accumulate in the body, which will combine with many important components of the human body, such as protein and enzymes, and affect many biochemical reactions in the body. Long-term intake will damage the brain, lead to dementia, and may also cause anemia, osteoporosis and other diseases, especially for the elderly, children and pregnant women with weak physical resistance, which may lead to developmental retardation and dementia. Pregnant women's intake will affect fetal development. The harm of anode magnesium rod is so great that the limitation of using magnesium rod to avoid safety accidents of water heaters is becoming more and more prominent. Because the water heater has not fully met the needs of washing, it is more for drinking. Such as washing vegetables, washing dishes, washing pots and making soup.
The heating is a slow-heating water heater, and the bacteria multiply seriously. The water in the water tank has a lot of sediment and cannot be cleaned. The water temperature is high, and it is easy to burn at high temperature.
6。 Ordinary water heaters realize gear adjustment through relays. Used to realize the conversion between power and water temperature. Because of the realization of high power conversion, it is easy to draw arc and produce electric spark under the impact of high current. Frequent failures and even fires lead to major accidents.
What are the hidden dangers of gas? The safety deficiency of gas water heater lies in that although it can be turned on immediately for heating, the combustion pollution is not environmentally friendly, and there are potential safety hazards (carbon monoxide poisoning often causes death), and the exhaust device is inconvenient to install. The kitchen and bathroom in modern family design are generally far away, and gas water heaters must be installed in life balcony according to national requirements, which leads to unnecessary drainage and waste in temperature difference bathing.
With the increasing shortage of energy supply, the state has stepped up efforts to save energy and reduce emissions, and various measures to restrict the use of natural gas have been introduced all over the country.
What are the disadvantages of solar energy? Solar hot water is the most energy-saving but unhealthy. Because of the slow heating, bacteria multiply seriously, and there are many sediments in the water in the tank, so it is not clean to wash. Washing vegetables and cooking with domestic water will affect health, and sediment will also affect the heating effect. It takes a long pipe connection from the roof to the room and needs to be installed in sunny places, such as roofs and balconies, which is inconvenient to install. Maintenance is difficult and expensive, and it needs to be cleaned every year.
In fact, in most parts of China, it is impossible to use solar energy in winter. It must rely on long-term electric auxiliary heating to meet the use.
Maximizing the value of life will force the rewriting and upgrading of products in the electric heating industry-Su Huier's "magnetic" water heater will soon become the guide for rewriting and upgrading!

Disadvantages of resistance wire heating water heater.
What are the characteristics of instant magnetic water heater? Safety of 1: the rotating water heater pioneered the patented technology of rotating magnetic frequency conversion heating. Contactless circuit design of the whole machine, unique hydropower separation structure. It uses alternating current to realize high-frequency conversion after rectification, indirectly does work on water without electric heater, and releases heat to heat water. The heater is induced by an external magnetic field. After water is induced by magnetic field, its own molecules collide to generate a lot of heat energy to heat water. Really separated water, electricity, people and machines, ensured the safety of use, and bid farewell to the era of passive leak-proof wall in this industry. The fault of relay contact circuit in industrial electric water heater is completely eliminated, the occurrence of electric spark is fundamentally eliminated, and all the disadvantages of poor circuit contact are reduced. The electric leakage accident caused by instantaneous high temperature when the resistance wire in the heating body is burnt out is avoided, and the service life of the machine is prolonged. 2. Energy-saving: the faucet adopts magnetic induction frequency conversion heating mode, which has high efficiency and fast heating speed, no need to preheat in advance, no power consumption and heat preservation, and can be used after starting for 5 seconds, making full use of electric energy, and the thermal efficiency is over 99%. The hydrodynamic circulation heat dissipation technology of the whole machine can effectively absorb the waste heat recovery of electronic power components, save energy and electricity, and will not age and corrode after long-term use, and the thermal efficiency of "magnetic energy" will never decay. Its heating adopts frequency conversion technology and dynamic water circulation cooling system, which saves more than one third of electricity.
Health: The rotating magnetic induction water heater adopts the patented indirect heating technology of "rotating magnetism" pioneered by domestic industry, which releases rotating magnetic ultrasonic waves in the process of heating water, magnetizes softened water while using magnetic induction heating, enhances the activity of water, effectively softens water and magnetizes water at the same time. Taking a bath with magnetized water for a long time has certain functions of beauty, health care, sterilization and dandruff removal. The heating element of instant water heater is made of PP-R material, which has good heat resistance. The Vicat softening temperature of PP-R 13 1.5℃ and the highest working temperature can reach 95℃, which can meet the requirements of hot water system in building water supply and drainage code. Long service life. The service life of PP-R can reach more than 50 years at working temperature of 70℃ and working pressure of (P.N) 1.OMPa, and it can reach more than 100 years at room temperature (20℃), which is hygienic and nontoxic. This material belongs to green building materials and can be used in pure water and drinking water pipeline systems. Corrosion resistance, no scaling.
4. Environmental protection: the magnetic induction frequency conversion instant electric water heater does not produce harmful waste gas, consumes indoor oxygen, produces no noise and has no impact on the environment. It is a pollution-free and environmentally-friendly high-tech product, which conforms to the current world trend, has obvious water-saving effect on life and saves the discharged water with insufficient initial water temperature. Long service life: the rotating magnetic water heater adopts unique "ultrasonic descaling technology" and never scales. Using high-frequency magnetic field and ultrasonic vibration heating, the scale is eradicated and the machine will never scale. Using ppr material as heating element has a longer service life and the thermal conductivity is only 1% of that of metal tube. When used for hot water insulation, it is not easy to dissipate heat, and the energy saving effect is excellent.
