Does the instant electric water heater consume a lot of electricity?
First, heating hot water under the same conditions, that is, the hot electric water heater saves about 40% electricity compared with the storage type (traditional electric water heater).
Second, the instant electric water heater does not need to be preheated for a long time, nor does it need to be heated and insulated at any time, saving electricity;
Third, the instant electric water heater is a water control machine, which can be turned on and off immediately, and will not cause heat loss and waste electric energy;
Fourth, it takes a short time to heat hot water under the same conditions, that is, the hot electric water heater. According to the law of conservation of capacity, under the same power supply voltage, the time is short and the power consumption is low;
5. Unique stepless speed change function (adjustable power), that is, the hot electric water heater can adjust the heating power at any time according to the different inlet and outlet temperatures, heat the hot water in a targeted manner, and save electricity in time;

1. The water heater won't catch fire. (There is no electricity, the igniter is broken, the microswitch is broken, the hydraulic valve is broken, and the water quantity is too small. ).
2. The water heater has a small fire but no big fire, so it can't be used normally. The solenoid valve is broken, the hydraulic valve is broken, the switch is broken, etc. )
There is a spark when it is opened, but it cannot be ignited. (the solenoid valve is broken, there is no gas, and the pressure of liquefied gas is too high. )
4. The bottom of the water heater leaks. (Water tank leaks, water valve leaks)
5. I can't open it repeatedly, and sometimes it makes noise. (The ignition needle is in the wrong position, the solenoid valve is broken, the tempering needle is in the wrong position, it won't burn, and so on. )
6. The water is not hot in winter and too hot in summer. (Gas pressure is low, hydraulic valve is broken, etc. The amount of water in the pipeline is too small, the hydraulic valve is broken, and it is impossible to adjust the amount of water, and the gas adjusting rod cannot adjust the firepower. )
7. The water heater can strike a fire, but it will go out soon. (Electromagnetic valve is broken, lack of oxygen, tempering needle doesn't work, etc. )
8. The water heater cannot be turned off automatically. (The hydraulic valve is not reset, etc. )

Some netizens reported that they used gas water heaters at home, which used to be normal. It's always closed after a while recently. It can catch fire after turning off the water, but it goes out soon, which is a headache. Let's analyze the reasons for the flameout of domestic gas water heaters.
The gas water heater is controlled by solenoid valve for gas source and electronic ignition. The Wan Jiale water heater automatically turned off two minutes after maintenance, mostly because the control module in the solenoid valve was damaged, and it could continue to be used after replacement. In addition: most water heaters are set with protection time, which can only be turned on for 20 minutes, and will automatically turn off after 20 minutes.
Causes of automatic flameout of gas water heater
First, the water heater has been used for a long time, and the internal joints are loose. Just tighten it, or replace it with a new one;
Second, if it has been used for more than two years, it may be that there is something wrong with the induction needle of the water heater and the conductive function is not good. Therefore, Wan Jiale water heater must be replaced and maintained.
Third, the igniter is broken. After striking a fire, the water heater will catch fire due to natural reaction, but it will go out after a few seconds due to insufficient heat induction. This requires replacing the igniter.
Fourth, the solenoid valve is broken.
5. The battery is dead and must be replaced;
Sixth, the water pressure is low, you can try to turn on the water heater in different periods.
Seven, sometimes this phenomenon happens because the air in the exhaust pipe flows backwards. You can solve the problem by installing a range hood at the smoke outlet.
Repair and maintenance methods of gas water heater flameout
The fire in the gas water heater has two main functions: one is to ignite the main burner with it; The second is to use it to continuously heat thermocouples. Thermocouple is an element that can convert thermal energy into electrical energy. It is installed beside the kindling, and the current generated by its heat controls the electromagnetic valve to open the gas supply channel of kindling, thus achieving the purpose of maintaining gas supply and continuously igniting kindling. After using the water heater for a period of time, it is easy to cause flameout and flameout. The reasons and treatment methods are as follows:
The root cause of failure is that the gas supply channel of kindling is blocked or can't maintain conduction. If the thermocouple or solenoid valve fails, or the nozzle of the fire is blocked, the gas supply channel will be blocked. When the thermocouple performance becomes worse, even if it burns red, there is still no fire after releasing the hand during ignition, and the sound of solenoid valve action cannot be heard. In addition to thermocouple failure, cracks or loose electrode leads may also lead to ignition failure. If you can't see the fire after releasing your hand, but you can hear the sound of the solenoid valve releasing, it is that the nozzle is blocked. At this time, the fire supply pipe can be removed and the dirty things in the blocked place can be poked out with thin copper wire. If there is a fire after the hand is released, but it goes out automatically soon, it is caused by a thermocouple. You can try to re-adjust its optimal heating position, which can usually eliminate the fault.
When the thermocouple is overhauled, it can be artificially heated. If heating can generate current, it is equipped with a solenoid valve. Press the valve stem after heating, and the suction is good, indicating that the thermocouple is in good condition. Put it back into the water heater and adjust the heating position of the heating end of the thermocouple under the condition of ignition. After several adjustments up, down, left and right, the fire will be maintained normally when it is in the outer flame of the fire and there is enough heating area.
