The gas water heater suddenly doesn t heat, what happens when the gas water heater doesn t heat?

With the development of the times and the progress of science and technology, gas water heaters have entered thousands of households, but many people do not know much about gas water heaters. For example, what happens when a gas water heater doesn't produce hot water? Next, let me lead you through this problem.

First, the gas water heater does not produce hot water. What happened? Gas water heaters are also known by another name, wall-hung boilers.

Although it has a smaller capacity than an electric water heater, it also provides a continuous source of hot water to meet our daily needs. It may be that the pressure of the gas is very low, or the gas pipeline is blocked, or the gas pipeline is leaking, or the mode of the gas water heater is not adjusted properly, etc. These can all cause the gas water heater to not heat up.

Because the main energy source of a gas water heater is gas, it relies on gas to generate heat. If the gas pressure is low or the gas leaks, it will reduce the amount of gas entering the water heater and therefore will not provide enough heat. 2. What are the advantages and disadvantages of gas water heaters?

1.The power source of a gas water heater is gas. In most regions, natural gas is usually much cheaper than electricity.

Moreover, gas water heaters are relatively small in size and do not take up a lot of space. It's very convenient and flexible, and it's very convenient to use. It doesn't take much time to warm up, and so on.

2.Its disadvantage is that when we connect the pipeline, we can't connect it for too long, otherwise a lot of water will be wasted in the process of transportation. Secondly, it is not suitable for installation in the bathroom.

During the bath, we can't adjust the water temperature, we can only use it after adjustment. Summary: The above are the main reasons why gas water heaters do not boil hot water.

As you can see from the above article, the main reason why a gas water heater is not hot is the lack of gas inside, which may be low air pressure or air leakage. So be sure to check in advance when using them to make sure there is no problem with the gas volume. Hope it helps.

The gas water heater suddenly does not heat, it may be that the water flow pressure is not enough, see if the filter screen is blocked, change the filter element to see if the water flow pressure is high, and it may be that the water heater is over, the life of the water heater is eight years, and there is a small part in it that will not automatically trip and will not be heated.

The gas water heater is not heating, what is going on? I think if you don't heat it, you may run out of gas, or it may be a poor contact.

1. The gas pipeline is blockedAfter the gas water heater has been used for a long time, the outlet nozzle will be blocked by debris, especially if the nozzle has not been modified, it will be easier to produce blockage, so it is recommended that you clean the gas pipeline in time to avoid blockage. 2. Low gas pressure gas water heater relies on gas to generate heat, once the gas is too little, it can not produce a lot of heat, there may be no hot water, generally when the air pressure is too low, you will hear the gas is intermittent boiling water, the sound is not forceful. Yes, so you can check whether the switch of the gas source is fully open and whether the hose has been bent, as this affects its air intake.

3. The mode is not adjusted well The gas water heater has a winter and summer mode, at the bottom of the equipment, there will be an adjustment button, if it is the summer mode, its water temperature will not be hot in winter, which is for the sake of saving electricity and gas in summer, and it should be adjusted to winter mode in winter, some people don't know, they may think that the water heater is broken. So you can do it according to the manual. 4. If there is a leak in the gas pipeline, the amount of gas in it is insufficient, and the water cannot be heated, so it is necessary to carefully check whether there is any damage in the bend of some pipelines.

5. Firepower, the amount of water is not adjusted, the fire adjustment can not be too small, the amount of water can not be adjusted too much, it is best to be in the middle of both, so that there will be no hot water.

1. The gas pressure of liquefied gas is too high or too low; The pressure after the liquefied gas pressure reducing valve should be adjusted to about 2800pa. In winter, the temperature is low, the vaporization rate of liquefied gas is slow, and the gas supply is insufficient. The LPG pressure reducing valve can be adjusted or replaced.

2. The rated gas pressure of natural gas should be 2000pa, and it is not easy to ignite when the pressure is small. It is necessary to confirm and adjust the secondary pressure of the low fire.

3. When the liquefied gas cylinder is used, it is turned upside down, and the residual liquid is poured into the gas valve of the water heater, resulting in the abnormal operation of the gas valve. The gas valve can be disassembled and cleaned, and the gas valve body must be replaced if the rubber film in the gas valve body is deformed or damaged.

4. The fan works abnormally, and the fan does not rotate. The fan needs to be replaced.

5. The solenoid valve is not opened, and the coil is broken. Most of the solenoid valve coil resistance should be about 100 ohms, the use of universal means to measure the resistance value, open circuit on behalf of the coil burned, need to replace the solenoid valve.

6. The voltage provided by the computer board to the solenoid valve is too small to make it open the valve. Measure whether the voltage of the solenoid valve is around DC20V. Check whether the 24V output voltage of the transformer is normal. In the event of a malfunction, the computer board or transformer needs to be replaced.

7. The proportional valve coil is damaged. It is necessary to check whether the voltage of the proportional valve is about 10V for small fire, about 15V for medium fire, and about 20V for large fire. Otherwise, replace the proportional valve.

8. The pulse igniter is damaged, resulting in no ignition. At this point, the pulse igniter needs to be replaced.

Answer the reason and maintenance method: (1) It may be that the gas path is blocked, such as the outlet nozzle has debris or blockage, which directly causes the water to be not hot enough. Remove the obstruction first, and then shift it according to the actual situation to restore the operation of the water heater to normal;

2) Maybe the water-gas linkage assembly is faulty; Replace the water ball valve, and the water-air linkage assembly can be changed; Other reasons and methods are as follows:

3) There is scale or carbon deposits in the copper pipe of the heat exchanger. To clean the vacuum tube, make a plan and implement it first, if the situation is not good, you can compress the cleaning cycle;

4) Gas filter and pressure reducing valve, there may be scale in the pipeline (pipeline), which can liquidate the fire channel. Waterways. Scrub the surface of the vacuum tube to avoid the moisture inside affecting the use effect;

5) Computer board failure, common in advanced machines. Scrub the surface of the vacuum tube to avoid the moisture inside affecting the use effect;

If the gas water heater is not heated, it should not be on fire, you can first check whether the water and electricity at home are normal, if the water and electricity are normal or not on fire, it is recommended to contact the manufacturer for after-sales inspection and processing.

See if the gas is gone and the water tank is leaking. If it is an aluminum water tank to be replaced, it is too unsafe, and it is not recommended to continue to use the flue machine, some brands of materials are too poor that the machine is cheap, and it will not take long for all kinds of problems to appear. It is recommended to use the 30-year-old brand of Shenzhou water heater, the copper water tank is easy to use, the thermostat is very good in the kitchen, the water temperature is very comfortable, and the Shenzhou counter on the fourth floor of Suning Electric Appliances in Xinshi Market, Baiyun District is sold, it is very real, and it is recommended to change Shenzhou.

The water heater water is not hot, which can be divided into: first, after the water heater is ignited, the gas has been burned, and the water has been heated but the water cannot reach the ideal temperature; The second is that the water heater is not ignited normally, the water heater does not ignite or does not ignite, you can check the reason why the gas water heater does not ignite.

The water heater has been lit on fire but the water is not hot, this situation is generally the reason for the excessive water output, which can be adjusted on the knob switch of the water heater; There is also the reason for the low air pressure, the gas (natural gas, liquefied gas, coal gas) entering the burner is less and cannot produce enough heat, resulting in the water is not hot, you can check whether the gas source switch is fully opened, whether the gas hose is tortuous, whether the cylinder switch is fully opened or whether the decompression flash is normal.

There are other reasons why the water heater water is not hot:

1. There is a blockage in the gas path, such as debris or blockage in the outlet nozzle, and some water heaters that have changed natural gas may not have the nozzle transformed to a suitable size or the secondary pressure has not been adjusted when it is transformed, such as Rinnai, energy rate and other water heaters;

2. The water-gas linkage device is faulty;

3. There is scale or carbon deposit in the copper tube of the heat exchanger.

4. Gas filter screen and pressure reducing valve, there may be scale in the pipeline, which can clean the fire channel and water channel.

5. Computer board failure, high-end machine is common.

The water heater water heater caused by the above 5 reasons is not hot and needs to be repaired by professionals.

Reasons why natural gas water heaters are not heating:

1. The gas pipeline is blocked.

When a gas water heater has been used for several years, there is a high chance that the outlet nozzle will be blocked by dirt.

Solution: In the process of use, the gas pipeline should be cleaned from time to time, so as to prevent the nozzle from being blocked.

2. Low gas pressure.

Gas water heaters generally rely on gas to produce heat. However, if there is not enough gas, the water heater will not produce enough heat. Generally, when the air pressure is low, you will hear the sound of boiling water from the gas, but this sound is very low.

Solution: Check whether the gas switch is turned on and whether the hose is bent.

3. The mode is not adjusted well.

In the process of using a gas water heater, many people don't know that it has a winter and summer mode, so many failures will occur when using it. If the gas water heater is in summer mode, then the water temperature will not be as hot in the winter.

Solution: Just turn the water heater to winter mode and the problem can be solved.

4. The firepower and water volume are not adjusted well.

The fire power of the gas water heater must not be too small, and the amount of water should not be set too much, it is best to set it in the middle of the two, because in this way the water heater will not appear hot water without heat.

Solution: If you don't know how to set it up, you can ask the repairman to help solve the problem.

What is the reason why the gas water heater water is not hot.

There may be a clogged pipe. Because many water heaters will have debris after being used for a long time, which will be blocked in the pipes, which will directly affect the water heating of the water heater.

It is possible that the pressure of the gas water heater is relatively low. The reason why it is called a gas water heater is mainly to generate heat by burning gas, if the gas pressure is relatively small, it will not produce a lot of heat, and naturally there will be no hot water.

It's possible that it's not set up. Because the gas water heater has a winter mode and a summer mode, there are adjustment buttons on its surface, and if the setting is not reasonable, there will also be a situation where it is not hot.

There is a leak in the gas pipeline. If there is a leak in the pipeline, there will be a shortage of gas and the water will not be able to be heated.

There are several reasons why the water heater suddenly doesn't heat up:1. It may be that the power supply is not connected, check whether there is a power outage at home, whether the socket is plugged in, and the plug-in board is not energized, etc.

2. It may be that the water heater is leaking, and the water heater has a leakage protection switch.

When leakage is detected, the power supply will be automatically cut off, and the wiring of the water heater will be checked for short circuits.

3. It may be that the heating rod inside the water heater is seriously scaled, which affects the heating efficiency and needs to be cleaned with descaling liquid.

4. Or the heating rod is broken, resulting in an unknown omen to heat the water, replace it with a new heating rod.

5. It may also be the thermostat of the water heater.

If it is broken, a broken thermostat will make the water heater continue to heat up, and then the water temperature will be too high, which will trigger the overheating protection and make the water heater lose power. You can open the right side of the water heater, and you will find a pei or a small red button to see if it jumps out and needs to repair or replace the thermostat.

There may be a clogged pipe. Because many water heaters will have debris after being used for a long time, which will be blocked in the pipes and make a mess, which will directly affect the water heating of the water heater.

It is possible that the pressure of the gas water heater is relatively low. The reason why it is called a gas water heater is mainly to generate heat by burning gas, if the gas pressure is relatively small, it will not produce a lot of heat, and naturally there will be no hydrothermal years.

It's possible that it's not set up. Because the gas water heater has a winter mode and a summer mode, there are adjustment buttons on its surface, and if the setting is not reasonable, it will also not be hot.

There is a leak in the gas pipeline. If there is a leak in the pipeline, there will be a shortage of gas and the water will not be able to be heated.

1. Generally speaking, the water heater relies on the heat generated by gas, if there is less gas or no gas, it may cause the failure. 2. Due to the long-term use of the water heater, it is very likely that the place of the internal outlet nozzle will be blocked by some debris, and the normal ventilation may be affected if it is not cleaned in time, so the problem of the water heater not heating will occur. 3. When the pipeline of the gas water heater leaks, it will also lead to insufficient gas, which will lead to the failure.

Suggested solutions: 1. First of all, you need to check whether the gas switch of the water heater is fully opened, if the gas switch is not opened, you can turn the gas switch completely on, and check whether the hose has aging problems. In the event of hose deterioration, contact a professional to replace the hose.

2. When the air outlet nozzle inside the water heater is blocked, be sure to contact a professional to remove it, and clean the nozzle, and do not install and disassemble it by yourself to avoid some other accidents. 3. If there is a leak in the gas pipeline after the inspection by professionals, it is necessary to repair the leakage in time, and then ensure that the gas volume inside is sufficient, and the problem of natural water heater not heating will be solved.
