As soon as the gas water heater is turned on, I smell the smell of gas

Gas water heaters.

As soon as I opened and smelled the smell of coal: reason 1: the gas combustion is not sufficient, because after the heating nozzle has been used for a long time, a lot of dust has accumulated on the upper area, blocking the nozzle, so that the gas is not fully burned, so the water is not hot.

You can open the shell, clean the nozzle with a brush, and you can use it. Reason 2: The in-line water heater, the smoke exhaust pipe is not windproof, and there is no pollution to the indoor air under normal circumstances, but if the flue is installed incorrectly and the pipe mouth is facing the wind direction, the exhaust gas may be poured back when the wind is strong, resulting in a gas odor; or flue gas backflow due to flue blockage.

This answer applies to most water heater models such as Haier EWH-80E5, Wanhe JSLQ20-12EV20, etc.

In general, the smell of gas in the water heater is the following problem:

1: The gas combustion is not sufficient, because after the heating nozzle has been used for a long time, a lot of dust has accumulated on the upper area, blocking the nozzle, so that the gas combustion is not sufficient, so the water is not hot. In this case, you can open the shell, clean the nozzle with a brush, and you can use it.

2: The water pressure is too small, because the water pressure is insufficient, the machine starts frequently in the process of bathing, and a large amount of exhaust gas will be generated at the moment of starting, which is the smell of gas.

3: In-line water heater, the smoke exhaust pipe does not have windproof treatment, and there is no pollution to the indoor air under normal circumstances, but if the flue is installed incorrectly and the pipe mouth is facing the wind direction, it may let the exhaust gas backfill when the wind is strong, resulting in coal odor; or flue gas backflow due to flue blockage.

4: The gas pipe interface is loose, or the anti-leakage rubber ring at the interface is aging, resulting in air leakage. You need to tighten the interface or break the anti-leakage rubber ring.

5: The ignition is faulty, and the ignition of the water heater is delayed, resulting in the ignition success of the gas after the magnetic suction door is opened. This one requires the ignition to be replaced.

6: The internal radiator of the water heater is damaged, resulting in air leakage, water leakage and other failures.

7: The exhaust pipe mouth is installed in the immediate room, in this case, the exhaust outlet needs to be moved out of the room and moved to the outside.

Water heater has gas odor treatment method:

1. First of all, drain the water in the water heater.

2. Remove all the vacuum tubes, tie a ball of cotton cloth with a long wooden stick with a cotton rope, the size of the cotton cloth should be slightly larger than the inner diameter of the vacuum tube, but not too big, feel a little resistance, slowly pass into the vacuum tube, rotate in, and then rotate out, and the vacuum tube should be filled with water. Finally, wash it again with clean water. Note that if the scale is not much, there is no need to clean it frequently, because when disassembling the pipe, it is easy to damage the sealing ring, and it should be carefully checked before installation, if it is damaged, it is necessary to replace the new sealing ring to ensure that there will be no water leakage.

3. Open the water inlet of the water heater.

4. Add the water heater descaler to the water storage tank.

5. Automatic thermal cycle for 20-30 minutes, so that the descaler solution fully touches all parts.

6. Open the drain and drain the cleaning liquid.

7. Fill the water tank with water and circulate it for another two minutes.

8. Drain the circulating water, clean and descale.

How can an electric water heater smell of gas? I think your home is an electric water heater. It definitely has nothing to do with gas. If there is a smell of gas, you can check if there is any leakage in your gas.

Dear, I'm glad to answer for you: Is it normal to have a smell of gas when you turn on the hot water faucet of a gas water heater? Answer: Hello, kiss, it is normal to have a smell of gas when you turn on the hot water faucet of the gas water heater Because it is ventilated first and then ignited by electronic ignition, there will be a smell of gas, but the amount is very small and it is safe, but when using the gas water heater, you should pay attention to good ventilation!

If you are not at ease, you can clear the professional to come to the door to test, the first qualified and normal installation of the gas water heater is not smelly during use. First of all, it is necessary to check whether it is a natural gas leak or an exhaust smoke leak. This requires a man or a woman or a man or a technician who directly finds an installation and maintenance master.

In order to allow users to find out in the shortest time after the gas leakage, the natural gas company will generally add a kind of odor to the natural gas, and you can't smell the single gas leakage, but we smell the odorant. If so, it is possible that there is a leak in the gas line entering the machine, and if the smell is the smell of carbon monoxide that has not been burned enough. That is smoke leakage from the exhaust flue.

Then it will be excluded in a targeted manner. Also, if the heating is a well-known brand machine, it may not be installed in place. Causes smoke leakage.

I don't know how long your heating service life is, generally used for many years of heating, this situation is more common, on the one hand, the flue is corroded and leaks smoke, in this regard, the fault is strongly eliminated. Thank you for your patience <>

。I hope you are satisfied with my service and I wish you all the best again! Peace and joy!

Dear, hello, I am glad to answer for you what to do if there is a gas smell when the gas water heater is usedAnswer: When the gas water heater is used, there is an emergency treatment of the gas smell, you can use a brush to brush the bubbling water (such as soapy water) on the joints of the gas pipe and other parts, if you find that there is a "blowing bubble" phenomenon, it is the air leakage point, try to block it (such as you can wrap several layers of tape paper, etc.). It is best not to use it for the time being, and ask a professional to repair it before using it.

When the gas water heater uses cold water, it will smell the smell of coal, this is because there is a certain air seal between the combustion chamber inside the gas water heater and the hot water pipe, when the water heater uses cold water, the air in the hot water pipe will be washed away by the cold water, so that the gas in the combustion chamber will be discharged, so that Youchang Lead smells the smell of coal.

Because the gas-liquid linkage valve of the gas water heater is broken, as soon as the water is boiled, the linkage valve will be opened, but it will not leak very much, and it can no longer be used at this time, because the gas is very dangerous, and you should call the after-sales service to ask the maintenance personnel to come to the door for maintenance.

The smell of gas when using cold water for a gas water heater may be due to a problem with the combustion system of the gas water heater. The working principle of a gas water heater is to generate heat through fuel combustion and heat the water flow, so as to give hot water to the user. If there is a problem with the combustion system, incomplete combustion or gas leakage, it will bleed and cause a gas odor.

One of the possible reasons is that there is a blockage in the combustion chamber or flue of the gas water heater, resulting in incomplete fuel combustion and the smell of coal bonding. In addition, the combustion system of a gas water heater also includes multiple components such as gas valves, igniters, and flame sensors, and if any of these components fail, it may lead to incomplete combustion or gas leakage, resulting in gas odor.

If you smell the smell of gas, first turn off the gas water heater and open the doors and windows for ventilation to avoid dangers such as fire caused by gas leakage. Then it is recommended to contact the maintenance personnel of the gas water heater or the staff of the gas company for inspection and maintenance. Do not easily try to repair yourself before repairing it, so as not to cause a greater safety hazard.

The smell of gas when using cold water in a gas water heater can be due to one of the following reasons:

1.Gas leaks: If a gas water heater uses gas as fuel, then a gas leak may cause a gas odor. If you suspect a gas leak, close the gas valve and open windows and doors for ventilation immediately, then contact your local gas company or emergency services.

2.Water quality issues: When water flows through the heat exchanger of the water heater, impurities and dirt in the water may be deposited on the surface of the heat exchanger, which may cause gas odors. You can try cleaning the heat exchanger of your water heater to solve this problem.

3.Incomplete combustion: If the combustion of a gas water heater is incomplete, it will produce some harmful gases, such as carbon monoxide and carbon dioxide, etc.

Whatever the problem, if you smell gas, you should take immediate action to ensure your safety.
