What is the reason for the inside of the wall hung boiler after heating?

1. The first situation: Generally, the sound may be due to the failure of the smoke exhaust pipe or heating rod during the operation of the water heater, which can easily lead to the sound of dripping in the process of using the water heater because of the hot gas running out.

2. The second situation: it may be that the installer is not very clear about the structure of the house when placing the water heater, and the water heater is a little loose after a long time, and it will make a dripping sound if it is not installed. The probability of such a situation where the installer does not install it properly is very small.

3. The third case: if the wall-hung boiler.

Over time, impurities on the fan blades can cause the fan to rotate out of balance, resulting in mechanical noise. In addition to impurities, such as the wind.

Loose machine screws or eccentricity of the fan shaft can also cause noise.

4. The fourth situation: if the pipes in the wall-hung furnace heating system are doped with solid impurities, the heating water will seep into the inside of the pump, resulting in more and more noise.

5. The fifth situation: the gas needs to come out of the nozzle, but the nozzle is easy to accumulate dust after a long time, which affects the flow rate of the gas outlet and forms noise.

6. The sixth situation: when the pressure is unstable, it will cause the flame of the wall-hung boiler to shake frequently, resulting in the pressure wave of the water tank oscillating to form a resonance and make noise.

7. The seventh situation: when a large amount of gas is accumulated in the heating pipe or the local water quality is poor, there will be boiling noise during use.

1.It may be that there is air in the wall-hung furnace, and this sound may appear when burning. 2.The wall-hung boiler has been used for many years, and there is a large amount of scale on the inner wall of the wall-hung boiler. This sound can also be seen when burning.

This situation is generally a relationship between thermal expansion and cold contraction. It can also be caused by other parts being loose. You need to ask a professional maintenance personnel to check and repair. FYI.

The wall-hung boiler keeps ringing because the wall-hung boiler fails, and the specific fault needs to be judged according to the actual situation.

If your own wall-hung boiler is screenless, you can judge according to the flashing frequency and color of the wall-hung boiler lamp, if your own wall-hung boiler has a screen, you can see the fault through the screen**, and then try to solve the problem according to the product manual.

1. When purchasing a wall-hung boiler, please choose the products of regular manufacturers of big brands. The wall-hung boiler of the big brand is more guaranteed in terms of quality, after-sales or service life.

2. Gas that is consistent with the product requirements must be used, and other gas must not be used as fuel! For example, natural gas must be used for natural gas wall-hung boilers.

3. Installation and maintenance should be carried out by the manufacturer's after-sales personnel or qualified professionals. In the event of a malfunction, you can simply rectify it by comparing the fault checking method on the product manual. If you can't solve the problem, please call the manufacturer's after-sales service, ask professional maintenance personnel to deal with it, and do not disassemble or repair it by yourself, so as not to cause potential safety hazards.

4. During use, please do not change the safety device and automatic adjustment device of the wall-hung boiler without authorization.

Gas wall-hung boiler is prone to noisy parts and reasons:

1. The fan is a device that uses a motor to drive the blades, and the lack of maintenance (dust removal, lubricating oil, etc.) after long-term use is easy to produce friction and noise.

2. The water pump is a power device that circulates the heating water, and it is also a motor device, which is easy to produce noise.

The core problem of wall-hung boiler is the efficiency and service life of heat exchange, and the biggest factor affecting these two aspects is the scale problem. Especially when we use domestic hot water, due to the need to constantly fill with new water, and the water quality in most parts of the country is hard, so that the scaling rate of the heat exchanger greatly increases.

It's better to get someone to fix it.

When the wall-hung boiler is ignited, it will ring, just like the feeling that there is something inside the water pipe. At first, the water pressure will be low, and the sound will be very loud, like the sound of stones clattering in an empty water pipe. I just raised the water pressure a little bit and it didn't sound.

Now it doesn't need to be pressurized, or it's ringing. It is also accompanied by the sound of running water.

It is the sound of the gas nozzle in the combustion chamber when the gas is ejected, and the sound will be similar to the whirring sound of the wind, mixed with the exhaust fan The sound of the exhaust fan is combined, which is a normal phenomenon.

1. When there is scale inside the boiler heat exchanger, when the temperature rises to more than 65 degrees, there will be a rumbling sound in the heat exchanger, and when it is serious, there will be a slight shaking sensation when touching the boiler shell, and the scale needs to be cleaned.

2. There is a lot of dust on the fan blades inside the boiler that has not been cleaned, and there will be a large noise during operation, similar to the noise of a car engine, and the boiler will shake violently when it is serious, and the sound is not like this problem according to your description.

3. The radiator makes a chirping sound when the boiler is just ignited, similar to the sound of folding wave iron sheet, which is the sound of deformation caused by the metal expansion of the heat exchanger fins due to local heating, which will disappear by itself after ignition for one minute, and there will be another time after the boiler is just shut down, this kind of sound is very common, and there is no need to do any treatment, according to the sound you described, it is most likely to be this reason.

The wall-hung boiler will inevitably fail during use, resulting in the unusable wall-hung boiler, in this case, we need to take relevant measures to solve it in time, but before solving the problem, we first need to understand the reasons for the failure of the wall-hung boiler, so what is the reason why the wall-hung boiler has been ringing? How to maintain the wall-hung boiler when it is not in use? Let's take a look!

1. What is the reason why the wall-hung boiler has been ringing is because the wall-hung boiler has failed, the specific fault needs to be judged according to the actual situation, if the wall-hung boiler is screenless, it can be judged according to the flashing frequency and color of the wall-hung boiler lamp, if the wall-hung boiler has a screen, you can see the fault through the screen, and then try to solve the problem according to the product manual. 2. How to maintain the wall-hung boiler when it is not in use 1. In the case of not using the wall-hung boiler, the power supply and valve of the wall-hung boiler should be turned off first, completely disconnected from water, electricity and gas, and it is recommended to directly unplug the wall-hung boiler, especially in summer, because the season often thunders and rains, if you do not pull out the plug of the wall-hung boiler, it is easy to damage the wall-hung boiler. 2. Clean the impurities and scale in the wall-hung boiler in time, if the magazines and dirt inside the wall-hung boiler are not cleaned for a long time, it is easy to affect the service life of the wall-hung boiler.

After a period of use, the surface of the wall-hung boiler may be stained, so it is also necessary to clean the outside of the wall-hung boiler, and you can use soft soapy water for cleaning. 3. After the wall-hung boiler is stopped, due to the instantaneous decrease in temperature, it may cause water leakage at each interface of the wall-hung boiler, so after the wall-hung boiler is deactivated, it is necessary to check the various interfaces of the wall-hung boiler to see if there is a problem of water leakage, and if necessary, contact professionals for maintenance in time. Summary:

Once the wall-hung boiler has been ringing, it is recommended that you immediately contact professional maintenance personnel, so as not to cause secondary damage to the wall-hung boiler in the process of self-maintenance.

Summary. Dear I am happy to answer for you, and I will inquire for you: What happens when the wall-hung boiler rattles after ignition?

It may be caused by deflagration during ignition, and the ignition parameters can be appropriately lowered and lowered. It may be caused by the lack of water inside the wall-hung boiler, and the water replenishment valve can be opened to replenish the water until the water pressure reaches about 2bar. It may be caused by the dust on the fan impeller being too thick and the impeller needs to be cleaned.

Dear I am happy to answer for you, and I will inquire for you: What happens when the wall-hung boiler rattles after ignition? It may be caused by deflagration during ignition, and the ignition parameters can be appropriately lowered and lowered.

The liquid blind draft may be caused by the lack of water inside the wall-hung boiler, and the water replenishment valve can be opened to replenish the water until the water pressure reaches about 2bar. It may be caused by the dust on the fan impeller being too thick, and the impeller needs to be cleaned dry.

Dear, hello, the result for your query is: according to the latest data shows that if the wall-hung boiler is just a clattering sound, it may be that the ignition needle is working, and it will generally only last for about 10s.

If the gas valve does not open when the ignition needle is ignited, and the gas valve is not opened for three consecutive ignitions, it will show an E1 fault. The noise of the gas wall-hung boiler mainly comes from the smoke exhaust system of the wall-hung boiler, which is mainly due to the noise that is easy to produce when the fan is working. When the blades of the fan are working, they rotate at high speed and rub against the air, which is easy to produce noise.

You can imagine range hoods, hair dryers, etc., all of which are composed of electric motors + blades, and they all have a certain noise in Hengshan.

Pro-knowledge development.

1. The wall-hung boiler always makes a clattering sound caused by the blockage: the wall-hung boiler has an abnormal sound when heating, which generally exists in the internal exchanger, and there is air or impurities in it, and the alarm type will produce a gurgling sound in the heat exchange process. Caused by combustion:

The wall-hung boiler has an abnormal sound when ignition, most of which is the sound of flame explosion, especially in the case of a large amount of air intake, it will be difficult to avoid some gurgling sounds.
