 Instant electric water heaters, as the name suggests, are hot water that is open and hot, without water storage without preheating. Therefore, the heat energy without preheating time is lost. When the water valve is opened, the water can flow through the machine to heat it in time. The water valve is closed and the machine automatically stops working. How much water is used to heat the water, there is no water storage type electric water heater remaining. Hot water consumption. In addition, the instant electric water heater, the time from start to hot water is relatively short, in a few seconds it can be hot water to reach the hot water temperature required for bathing, about 45 degrees, really save water, save Electricity. Although the power is relatively large compared to the water storage type, the power is not equal to the energy consumption, and the energy consumption = power * time. That is, there is no warm-up time in the hot type. If the same bath time is used, it can save more than 40% of electricity than the heat storage type.
The instant electric water heater is heated and flows out when the water flows through the heater, and there is little residual water in the heating body, and the hot water temperature during the bathing is generally not higher than 45 degrees, so the water does not generate scale during the heating process of the water ( Scale production must meet two conditions: heated water is relatively stationary, heating temperature is above 75 degrees). In the heating process, the water flow continuously flows through the heating element to remove heat, and the surface temperature of the heating element is relatively low, so the damage rate of the waterway and the heating element is correspondingly reduced, so that the electric water heater The service life is also longer than that of the storage type electric water heater. Generally, it is 2-3 times of the storage type electric water
heater. The advantage of the hot electric water heater is that it can realize low water pressure start, as long as there is water flow. Starting the heating body, in general, the start of the gas water heater should be above 0.02MPa, and now the general high-rise building water pressure is insufficient, after the pressure can reach the normal use of the gas water heater. Therefore, Shanghai Youbo Instant Electric Water Heater is your wise choice!

Two . Product Knowledge Q & A:
Consumers often have two misconceptions:
① wrong – big on power consumption!
Let’s take an example. Heat the same amount of water to the same temperature. It takes 1 hour to power 2KW and consume 2 degrees. It takes 2 hours to power 1KW and consume 2 degrees. As a result, the power consumption is the same (power consumption = power × time, 1 degree power = 1 KW / hour). The low power not only does not save electricity, but it wastes a long time to heat up!
2 wrong – high power is dangerous!
The power of 1 watt and 10000 watts is the same, because the voltage is 220V. The magnitude of the damage depends on the voltage and not the power; the warning signs we see everywhere are: high voltage danger! Never seen: high power danger!

It is truly safer and more Energy-saving, long-lasting use, no scale, safe, no hidden danger, longer life, more than ten years of service life. Ubo water heater is the most ideal choice for consumers.
8. What is the energy consumption of ordinary water storage electric water heaters and instant electric water heaters ?
Take a 40-liter water storage electric water heater as an example: the power is 1500W, the average heating capacity to the rated temperature is 2.6 degrees, and the average daily energy consumption is 0.97 degrees, that is, daily heating, total energy consumption. 3.57 degrees, in which the heating energy consumption depends on the daily hot water consumption. If you do not use the electric water heater, the daily energy consumption is only 0.97 degrees, taking room temperature 20 degrees as an example, the family of 3 bathing for 10 minutes, heating to 42 Degree of hot water, that is, about 3KW, 0.5 hours (10 minutes × 3 people) × 3 degrees = 1.5 degrees. Generally 40 liters of water storage type can continuously produce 42 degrees of hot water for about 20 minutes. It can be seen that the thermal type has to save more than 40% of electricity.
Nine, how to make you use the water heater is convenient and fast?
In fact, with the development of science and technology and the improvement of people’s consumption of daily life, the birth of the instant electric water heater is also the requirement of this era. Instant electric water heaters have just been developed in the past ten years. As we all know, traditional electric water heaters have the following disadvantages: bulky, unsafe, slow heating, etc., and Shanghai Youbo instant electric water heaters make up for these shortcomings. It is instant and hot, providing consumers with more convenient and fast water heater products.

Eleven, Ubo instant electric water heater and related products comparison table :

Youbo instant hot water heater

Small, safe, fast, energy efficient, convenient, environmentally friendly, lasting, etc.

Storage water heater The water storage type electric water heater is bulky, has a long warm-up time, and has limited water storage capacity. It is no longer suitable for the fast pace of modern life. 

Gas

With the development of the “ forbidden direct push ” campaign, the safety of gas water heaters that have plagued consumers for many years has also been greatly improved. Moreover , the implementation of the national “ West-to-East Gas Transmission ” policy has also provided a certain space for the development of gas water heaters. However, due to the installation location and other reasons, the gas water heater causes the cold water in the front section to be long when the pipeline is used long, the water pressure in the high-rise residential building is low, and the accident frequency caused by the improper use of the gas water heater is relatively high, so that the safety psychology of the consumer cannot be completely eliminated. Further development of gas water heaters.

Solar water heaters As for solar water heaters, the main factors are large and bulky. The main engine must be installed on the roof. Because it has to withstand the wind and the sun, the quality of the products is very demanding (and there are many domestic solar manufacturers, The situation of the explosion of the external explosion tube often occurs, and because of China’s vast territory, the impact of the climatic environment is very different, and even the rainy weather and sunshine hours are not suitable for use. In addition, solar water heaters will also affect the appearance of the city, so some cities and residential communities are prohibited from installing solar water heaters (many urban communities do not allow the installation of solar water heaters). At present, the mainstream storage water heaters are bulky, have a long warm-up time, and have limited water storage capacity. They are no longer suitable for the fast pace of modern life. 

Twelve, Ubo fast electric water heaters have unparalleled advantages compared with traditional water heaters. 
1. Compared with ordinary water storage electric water heaters,
ordinary storage type electric heaters are cumbersome in appearance, long in heating, consume energy, breed bacteria, etc. .
More energy-saving under the
same conditions, the energy consumption of the two is the same; but because the hot water of the ordinary storage-type electric water heater is forced out by the continuous injection of cold water, the temperature of the hot water in the tank will soon be The reduced cold water injected will cause only half of the heated water to be used, and half of the water will be heated in vain. And Ubo fast electric water heater is ready to use immediately, no need to heat excess hot water, no need to keep warm, more than 40% energy saving compared with traditional water storage type electric water heater.
More convenient to use
Ordinary storage type electric water heaters have to go through a long preheating process before use. In winter, the volume is too small for hot water, and the volume is as large as 80 liters to wait for several hours of warm-up time. And the Uber fast electric water heater is ready to use immediately, without waiting.
More beautiful installation The
ordinary water storage type electric water heater is bulky, bulky and inconvenient to install; it destroys the overall decoration effect of the bathroom, and there will be an event that may fall for a long time. The Uber fast electric water heater is small in size, and the elegant and luxurious classic appearance not only enhances the bathroom decoration effect, but also brings you an unparalleled bathing experience.
2 , compared with metal instant water heaters
Metal instant water heaters generally use steel cup electric heating rod technology to produce fast electric water heaters
1. Metal heating body is a combination of steel cup heating rod combination is a technology.
2. During the heating process of the metal heating body water heater, the calcium and magnesium ions in the water are decomposed by heat and condensed on the surface of the metal heating body with high temperature. After a long time, a thick layer of scale is formed. It seriously affects the heat dissipation of the metal heating body, and the heating time is prolonged and the electricity is consumed. However, the heat energy of the heating wire is not transmitted to cause the surface of the metal heating body to burst, thereby charging the water and endangering the life safety of the shower.
3. The water heater of this kind of metal heating body is inevitable due to its congenital defects of scale formation, which may occur during the use of electric leakage or bursting. In today’s people pay more and more attention to safety awareness to solve the problem of water heater scaling is a matter of urgency, consumers must carefully consider the scale problem when purchasing electric water heaters.

4. The most remarkable superiority of Ubo non-metal heating element is that it is resistant to quenching and rapid heat, high pressure resistance, faster heat conduction, higher thermal efficiency, no scale formation and long service life. All these superior properties have determined that it is the heating element of the instant electric water heater. It is the best material at present. It completely solves the shortcomings of the traditional metal heating body, which is easy to corrode and easy to scale. It is truly safer and more Energy saving, longer use, no scaling.

Comparison with the gas water heater
easier to use
different from the hot water heater instant electric water heater can achieve the biggest advantages is achieved Free Free water pressure start pressure, i.e., as long as there is water flow, can be started. The start of the gas water heater is realized by the pressure of the water. The basic working principle is that the cold water enters the water heater, flows through the water and gas linkage valve, and simultaneously pushes the DC power micro switch to turn on the power and activate the fat igniter. Open the gas transmission electromagnetic valve and continue to automatically re-ignite through the pulse igniter until the ignition successfully enters the working state. In this way, under low pressure (lower residential water pressure is low, especially during peak water use), the user may not start normally, and the user opens the faucet, but only cold water flows out. In general, the starting water pressure of gas water heaters is above 0.02Mpa.
More safe
From the structural point of view, Ubo electric water heater adopts Hall ST flow sensing technology, no pressure is required, as long as there is water flowing, it can be started, thus realizing zero pressure starting. Hall ST

Flow sensing technology utilizes high precision microelectronic components to sense fluid conditions. As soon as the liquid changes dynamically, a digital signal is sent to inform the computer control system to initiate a series of actions. The starting structure of the gas water heater is only a pressure switch. When there is water flow, there must be a certain pressure to press the switch to start the ignition. According to the theory of fluid mechanics, the pressure of the liquid will decrease when flowing, and even zero pressure will occur. That is to say, the liquid initially flows under a certain pressure, but after flowing, the pressure in the moving fluid is reduced or even zero. Thus, there is a case in which, during the use of the gas water heater, the water pressure drops due to an increase in the water consumption of the lower floor, which is insufficient to press the pressure switch, so that the water heater is turned off, if the flameout detecting device fails. Gas leaks, affecting your health or may cause a disaster.
More energy-saving
In terms of product working principle and structure, it is determined that fast electric water heaters are more energy efficient than gas water heaters.
Natural gas is a non-renewable natural resource that is getting more and more tense; prices will only become more and more expensive. The mainland is now generally at 2.2 yuan / 1 cubic. While electric energy is a renewable green energy, it can be obtained in a variety of ways. With the vigorous implementation of national low-carbon environmental protection and the continuous development of technology, electric energy will become cheaper and cheaper. The current household electricity price is on average at 0.56 yuan / 1 degree.
A certain amount of energy required to heat a certain amount of water under the same conditions. However, since the heat of combustion is heated by open flames, it is unavoidable to be in contact with the surrounding air, so that a large part of the heat is absorbed by the air, and the heat efficiency cannot be high; while the fast electric water heater uses electric energy, and the heating body is in the water. The center is heated outwards, and the heat energy is completely absorbed by the water flow first, and the heat loss is extremely small; the thermal efficiency of the heating body is as high as 98% or more. Moreover, the exhaust gas generated in the operation of the gas water heater will also smoke the black wall and pollute the living room environment. It is necessary to install ventilation in the compartment to affect the health of the body. The country has banned the sale of inline gas water heaters.
4 , compared with solar water heaters
Solar water heaters in the use of super-cold, overheating will cause the glass tube of the heating body to burst;
bulky installation is limited, the
price cost and maintenance costs are high;
Hot summer and cold winter, by the climate of the winter need electric auxiliary heating;
pressure affect the amount of water, inconvenient to use;
water for a long time stand still vulnerable to bacteria and microorganisms, using a long inner wall will have a scale;
Yubo fast The electric water heater does not have the above problems at all. So Uber water heater is one of your wise choices!
Thirteen, the relationship between the water temperature and heating power of the hot water heater?

3. Uber water heater product technology introduction
Instant water heater product technology:
A, Shanghai Youbo instant hot water heater works?
The working principle of the U-bo hot electric water heater is to complete the instant heating through the closing of the thermostat. The principle is to convert the electric energy into heat energy reasonably. It is one of the ideal heaters at present. It can adjust the working temperature and power. Under the rated flow rate, the water temperature can be increased by about 7 °C per kilowatt. The hot water heater can get hot water below 60 °C. The temperature meets the needs of multi-channel water supply for home bathing and hot water.
B. What is the working principle of other brands of water heaters on the market? What is the difference?
There are several different water heater heating bodies on the market. They work differently, but all have one thing in common. They all make cold water turn into hot water in different ways. The heating principle of the electric water heater is to convert the electric energy into heat energy to heat the cold water to reach the required hot water temperature. The working principle of solar water heaters is to convert cold energy into hot water by converting light energy into heat. The working principle of a gas water heater is accomplished by heating an open water vessel with an open flame. An air source water heater is a heating method in which water in a container is heated by energy to achieve heating. and many more.

They have the necessary connections and differences between each other. From the above explanations, they can see their differences and connections.
C, What is the high-end instant electric water heater technology? What role?
Youbo high-end instant electric water heater adopts dual-mode double-rotation circulating heating technology, which rapidly heats the high-speed circulating water flowing in the multi-passage to form a unique double-rotating stereo heating superconducting water flow with unparalleled heating efficiency. The thermal inertia is extremely small, the heat energy is completely absorbed by the water, and it is not easy to form scale.
D, what are the patents for the Uber instant electric water heater? What is it?

Youbo instant electric water heater, through its own research and development and continuous improvement, has many patents; including design patents, invention patents, utility model patents, etc.
E, the control part of the Ubo instant electric water heater, what to take technology?
Youbo touch-type digital frequency conversion intelligent constant temperature adjustment device, the control part of Youbo instant electric water heater adopts independent programming IC intelligent temperature measurement and water flow control technology.
Within the range of setting the water flow fluctuation, the chip automatically calculates the instantaneous heating power according to the small change of the water flow, and transmits it to the heating system in time, and automatically adjusts the power supply to maintain the set constant temperature water temperature. In 2010, Youbo promoted the instant water heater constant temperature control system in China. Over the years, Youbo people have been adhering to the leading quality, service leading and leading technology concepts, and have accumulated a number of patented technologies:

1. Ubo intelligent constant temperature patent control technology patent number: 200720311032.9 . Ubo intelligent constant temperature control system is controlled by Fujitsu 8-bit MCU single-chip microcomputer, which has excellent performance, safety and reliability.

The MCU is the core component of the thermostatic control system. The function of the control system is equivalent to the human brain, so the importance is self-evident.

The rich hardware resources of Fujitsu MCU ensure that Uber intelligent constant temperature control system perfectly realizes powerful functions such as “PID fuzzy control” and “adaptive control”.

Fujitsu MCU’s superior anti-interference performance ensures that the system is protected from external EMC electromagnetic interference. The intelligent transient control system fast transient pulse group immunity test reaches 4KV (national standard is 1KV). The electrostatic discharge immunity test reached 8KV (national standard 4KV).

2 , thyristor “stepless” power regulation and PID fuzzy adaptive control technology achieve a perfect combination .

Uber intelligent constant temperature control system temperature adjustment is faster, more accurate and more stable. Let the water heater products say goodbye to the “hot and cold” era. 3-5S rapid hot water, the outlet water temperature reaches the set temperature ± 2 °C adjustment time 4-15S , constant temperature adjustment time 5-20S , outlet water temperature control accuracy ± 0.5 °C, temperature overshoot < 2 °C.

Ubo intelligent constant temperature control system uses the US ST company’s BTA41/600B thyristor as a soft switch for power regulation control. Under normal use, the maximum working current of the thyristor can reach 40A. The MCU achieves the purpose of adjusting the output power by controlling the conduction angle of the thyristor or by controlling the on-off ratio to achieve the purpose of adjusting the output power. The minimum power adjustment unit of the constant temperature control system is 1% of the total power of the machine, ensuring that the outlet water temperature is ± 0.5 °C. Pkbazaar.pk

Note: SCR is used to adjust the output voltage to achieve stepless power regulation. Therefore, some products promote the so-called “stepless frequency conversion” control is not correct, it is a false propaganda. In fact, as a water heater product power adjustment using voltage regulation control is very effective, very ideal control method.

Ubo intelligent constant temperature control system calculates the required heating power by detecting the inlet water temperature, the outlet water temperature and the water flow rate, and realizes the required power through the stepless adjustment of the output voltage of the thyristor to reach the set outlet temperature. . The factors such as the power voltage, the water inlet temperature, the water temperature, the water flow, the power of the heating body, and the thermal efficiency of the heating body all affect the output power, and some factors may change at any time, such as: power supply voltage, water flow, water inlet temperature, etc. Simple proportional control methods cannot achieve precise control. Youbo intelligent constant temperature control system can automatically learn to adapt to the changes of various factors, through the “PID fuzzy adaptive control technology” and other modern control technology to achieve perfect thermostatic control effect.

3 , Youbo 360 ° electronic anti-electric wall patent technology (patent number: ZL 2007 2 0178140.3 ) to ensure a safer product.

Youbo intelligent constant temperature control system has 360° all-round leakage safety protection measures, with protection functions such as leakage circuit self-test E5 , leakage protection E2 , PE grounding wire with live protection E9 , LN incoming line and reverse protection E9 .

Leakage circuit self-test E5 : The controller will perform self-test of the leakage circuit when the power is on. If the leakage coil is open or the leakage detection circuit is faulty, the controller will stop working immediately, shut down and display the fault code E5 , and the buzzer will sound 5 times. Automatic recovery after the fault is cleared. The self-test function of the leakage circuit is very important. If the leakage detection circuit itself is faulty, normal leakage protection will not be possible. Some products do not have self-test function of leakage circuit. When the leakage detection coil is damaged or not installed at all, the machine can still work normally. This product has obvious safety defects!

Power leakage detection E2 protection : At any time, when the leakage current is greater than 10MA-20MA , the controller will stop working immediately in 50MS , cut off the power supply, display fault code E2 , buzzer will sound 5 , when the leakage fault is eliminated, power off After re-energizing the fault code, it can be cleared.

    PE ground line charging detection E9 protection : At any time, the detected PE ground line voltage (as opposed to the (machine connected to the metal casing, or is connected to outlet) N line) peak is larger than 100V , the controller immediately stops working, fault code The buzzer sounds 2 times and the power failure code can be cleared. Charging the PE ground wire may cause the water to be charged.

     LN incoming line reverse detection E9 protection : At any time, when the LN incoming line is detected to be reversed, the controller stops working immediately, the fault code E9 is displayed , the buzzer sounds 2 times, and the power failure fault code can be cleared. LN reverse will increase the risk of machine leakage.

    E9 protection can prevent the following two types of electric shock hazard: 1. The PE grounding wire itself is charged; 2. The PE wire of the power supply incoming line is disconnected, but the metal casing of the machine is leaking, and the machine is powered by water.

The difference between  E9 protection and E2 leakage protection: E2 is the protection when actual leakage is required, that is, leakage and then protection. The E9 protects the alarm when there is a risk of leakage but the leakage has not yet occurred. For example, the grounding wire of the machine is charged, the outer casing is charged or the water is charged. At this time, there is danger of leakage. When someone turns on the water heater to start heating, the leakage current is generated. At this time, the human body is exposed to electric shock, and the E2 leakage protection can be operated. However, since the machine can only cut off the power supply L and N lines, the PE grounding wire cannot be cut off , and the electric shock cannot be eliminated. However, thanks to the E9 protection function, the user will not open the water supply when the E9 protection alarm has occurred, so the occurrence of the code can be avoided.

When E9 protection occurs, it needs to be eliminated by professionals. Lead E9 possible protection reasons are: . 1 , the PE poor ground grounding line an induced voltage; 2 , the power L , N line reversed; . 3 , the PE ground line charging, and the L line short circuit and the like.

When the PE line of the power supply line is disconnected, the E9 fault may sometimes be undetectable , so the installer needs to confirm that the PE line is well grounded.

When the PE line of the power supply line is disconnected, the LN line connection can be detected if the grounding resistance of the inlet and outlet pipes is small .

When the user is poorly grounded or has no grounding, an E9 protection fault may occur . Solution: 1. Good grounding; 2. Cancel the protection function.

4 , dual switch control patent technology, safer, more reliable and more durable.

The intelligent constant temperature control system ensures that each set of heaters uses a 30A relay and a 41A thyristor for dual-switch control, completely eliminating the dry burning caused by individual relay contact sintering or thyristor breakdown; Intelligent constant temperature control system Ensure that the relay operates under zero current load, effectively eliminating the contact arcing caused by the action under high current load, resulting in contact sintering, and the relay contact life is extended by 10 times. The thyristor is a non-contact soft switch, and the normal service life is much longer than the relay contact. Therefore, the soft and hard dual-switch control technology ensures that the overall life of the system contacts is extended by a factor of 10.

Defects of conventional control methods :

1 single relay control. The relay has a load action, and the contact is arced, which causes the dryness of the contact to occur frequently, and the service life is short and unsafe.

2 single thyristor control. If the design is defective or high voltage or overcurrent causes the thyristor to break down, it will cause dry burning and is not safe.

3 dual relay control. There is a relay with a load action, the contact pulls the arc and causes the contact to sinter, and the service life is short, which is safer than the first two methods.

5 , reduce power attenuation, extend the life of the heating body. Ubo intelligent constant temperature control system adopts the most advanced software control technology to ensure that the power attenuation of quartz heating body is reduced to a very low level. At the same time, it is ensured that the usage time and the power consumption ratio of each heating pipe are the same, and the service life of the heating body is effectively ensured.

6. Reduce the sound of the heating body and reduce the flashing of the light. Uber intelligent constant temperature control system adopts the most advanced software control technology, which can reduce the heating body sound and reduce the lamp flicker phenomenon, and is at the optimal level in the same industry.

7. Fuzzy power selection: The power rating is blurred, the power is freely set, and the maximum power is freely set according to the user’s actual power environment, and the product adaptability is stronger.

8 , using water Hall sensor when the sensor control flow, the water flow changes less temperature fluctuation, and dry completely eliminate the phenomenon.

The Hall water flow sensing flow sensor can instantly detect the current flow rate and changes, ensure timely and effective power regulation during the control process, and effectively reduce the effluent temperature fluctuation during the flow change process.

The Hall water flow induction flow sensor adopts the pulse detection mode. When there is no water flow, it is impossible to generate a pulse, which can completely avoid the “dry burning phenomenon” caused by the switch being stuck due to the flow switch mode. When there is water flow, the Hall water flow senses and sends a pulse signal, which can realize low water pressure start, which is more convenient and comfortable to use.

Ordinary products use mechanical water flow sensor switches, the reaction is not sensitive, the water flow and water pressure requirements are high, and it is impossible to avoid the phenomenon that the water flow is stuck and the heat is dry.

Ordinary products photoelectric water flow sensor switch, the reaction is not sensitive, the water flow and water pressure requirements are high, and the failure of the photoelectric element to avoid the accidental heating and dry burning phenomenon cannot be avoided.

9 , 11-fold fault alarm and protection functions: triple over-temperature protection, leakage protection, insufficient water flow prevention protection, dry burn prevention protection, sensor fault protection, heating power abnormal protection, controller self-fault protection, etc. 11 kinds of fault prevention and protection.

The 2013 model will feature a fully thermostated concept controller with an electronically regulated valve that will automatically adjust the flow to achieve a constant water temperature in any environment.

The 15 and 2 019 models will increase the quartz heating body white tube and black tube program selection function.

In 2019, the controller provided by our company was set to the white tube program state, and the user can change the status of the black tube program on-site as needed.

White tube program description: When using this program, the advantage is that the sound of the heating body is small, and the sound is smaller when using the black tube; the disadvantage is that the incandescent lamp on the same line and the inferior energy saving lightness may be caused during the heating process of the water heater flicker. From the current experience, there may be 3-5% of customers complaining. If the customer requests a replacement, the program selection function can be used to allow the installer to choose to become a black pipe program. However, it should be noted that if a black tube program is selected using a white tube heating body, the sound may be too large.

The black tube program description: When using this program, the advantage is that the lamp does not flicker; the disadvantage is that the sound of the heating body is large, the sound will be reduced when the black tube is used, and the sound will be too large when the white tube is used.

Our quartz tube heating element has antifreeze protection running function.

In 2019 , the control panel control program added the anti-freeze protection operation function of the quartz tube to avoid the freezing crack of the quartz tube at low temperature.

When the machine is energized, non-heated and the inlet and outlet temperatures are both below 3 °C, the machine enters the antifreeze protection operation. During the freeze protection operation, the display flashes at 1S frequency.

When one of the inlet or outlet temperature is greater than 6 °C, or the HT1 overtemperature switch is disconnected, the freeze protection operation is exited.

During the antifreeze operation, the output power of the machine will be less than two thousandths of the rated power. For example, the rated power is 8500W , and the output power of the antifreeze operation is less than 17W . Especially for the big cold wave at the end of last year, the temperatures around the country are significantly lower than in previous years, and various disasters have occurred, including our series of water heaters, explosion of gas, and cracking of electric water heaters. Our products have increased in 2013. The anti-freeze protection operation function, as long as the power is off, the shutdown state can also fully protect against frost, greatly reducing the impact of natural disasters on our products, greatly improving the reliability and safety of the products. Therefore, we have been in the forefront of the industry for product development and core technologies.

VII. Precautions for product use
Safety precautions: (See product installation manual for details)
8. Home decoration small common sense
Focus on decoration before decoration
1. More and more household appliances, special electric wires step by step to
modern home appliances, not only air conditioners To take the special line, we must also consider the installation of electrical appliances such as bathroom electric water heaters, Yuba, kitchen induction cookers, microwave ovens, electric faucets, etc. Due to home decoration, the wires are all buried in the wall. If there is a safety problem or the electrical load is too high, Replace it at any time, so the new bathroom and kitchen decoration must be reserved 4~10

Copper core wire above square millimeters. In addition, we must use the national standard line produced by regular manufacturers to ensure circuit safety.
2. Multi-channel water supply should be cautious, water leakage, and heat preservation are troublesome. Pkmarts.com
Multi-channel water supply will be troublesome in the future.
Many families connect the whole family water pipes together and provide hot water by a water heater. Because the water pipe is buried in the wall, as long as there is a leak, the whole family’s hot and cold water system will be completely paralyzed, and the wall maintenance should be broken.
The hot water pipe should not be too long.
If the water pipe is too long, it is necessary to wait for the water in the water pipe to be discharged before it has hot water. It takes time, water and electricity.
Pre-design the location of the water heater, avoid the trouble to
determine the location of the hot water such as bath, wash basin, sink, etc. It is best to separately install the instant electric water heater and the small kitchen treasure, which is more convenient, more time-saving, and saves electricity. . The water heater is as close as possible to the bathing position, and the temperature adjustment is convenient; the power supply box is slightly higher than the water heater, which is safe and beautiful.
