"0,000 Jiale , Le Wanjia" is a classic slogan, which also allows many consumers to recognize the "Wan Jiale" brand and choose their products. However, recently, Mr. Wan, a consumer in Nanchang, Jiangxi Province, reported through the 24-hour news hotline of " Urban Live " 0791-88316800 that he bought an "Wanjiale" gas water heater for his parents' home, but there were constant problems after installation and use. Not to mention "Lewanjia", even the old couple couldn't wash it if they wanted to take a hot bath and didn't dare to wash it. What's wrong with this?
html This "Wanjiale" gas water heater at Mr. 20,000's parents' home was purchased at the Siping Electric Appliances Nanchang Laofushan store in May this year. However, after installation and use, the water temperature was uncontrollable many times, and Mr. Wan gave a demonstration to the reporter on the spot.During the demonstration, Mr. Wan first presetted 39℃ hot water, but the reporter found that after the water heater was working, the maximum temperature of this "Wanjiale" water heater once reached 50℃, and the "air pressure, water pressure" icon flashed at the same time.
Then, the reporter set the water heater to 60℃. This time, after the water temperature reached 46℃, the "air pressure" icon began to flash, and the water temperature could no longer rise.
0,000 told reporters that what I just tested was the hot water from the kitchen sink. If the hot water from the shower shower in the bathroom is turned on, the water temperature will also be uncontrollable and will be lower than the set temperature. Afterwards, Mr. Wan adjusted the set temperature of the water heater to 42℃. However, after the water heater works, the water temperature is only about 38℃ and 39℃, and it cannot reach 42℃. At the same time, the "air pressure" light on the display of the water heater began to flash again.
From the instruction manual of this "Wanjiale" water heater, the reporter learned that the "air pressure" and "water pressure" flashing on the display screen are an intelligent protection of the water heater. When the water pressure is too high or too low, the "water pressure" icon flashes. Although it can be used normally, it may affect the comfort of use. When the air pressure is too low, the "air pressure" icon flashes. Although it can be used normally, it may affect the comfort of use.
htmlMr. 60,000 told reporters that more than a month after I bought this "Wanjiale" water heater, the problem of uncontrollable water temperature began to occur. At that time, the maintenance master of Wanjiale came to check and said that it might be caused by the aging of the kitchen and bathroom pipelines. For this reason, Mr. Wan renovated the kitchen and bathroom, and updated all the water pipes, gas and other pipelines that could be replaced.
"We thought that after the renovation, the water heater should be fine. We can take a shower normally. As a result, after we installed the water heater, it still cannot be used normally and the temperature cannot be controlled." Mr. Wan said that he reported the repair again. The master said that the water pressure and air pressure of the water heater were all problematic, otherwise the gas stove display screen would not flash. Mr. Wan believed that this should be a problem of product quality.
"Because I live on the second floor, my brother's house is on the third floor, and another brother's house is on the fourth floor, both of which come from a water pipe. They also use the gas water heater , and this is not the case," said Mr. Wan.
"Wanjiale" suspects that there is a problem with the water pressure and air pressure. Consumers say that there is no
Since Mr. Wan lives in a self-built house, the water supply of the entire building is connected from the same municipal chief, and the same is true for gas. Why is the only gas water heater on the second floor in the home of his parents cannot be used normally? Is it because the brand of the water heater is different?
In order to confirm his guess, Mr. Wan took the reporter to his brother's house on the third floor. A gas water heater from other brands was installed here. After setting the temperature to 39℃ that was consistent with the previous one, the reporter began to conduct a comparison test and found that this water heater could reach the set temperature stably.
Then, the reporter set the temperature of the water heater to 60℃. As a result, he saw that after the heating, the water temperature finally stabilized at 60℃.
0,000's brother told reporters that he bought this water heater for more than 900 yuan, which is half cheaper than the 0,000-yuan Jiale water heater . Mr. Wan said that compared with the effects of the two units, it feels like Wanjiale is worse than ordinary machines. Is there any problem with the air pressure and water pressure in
? On-site inspection of the gas supply and water supply department: speak with data!
The water pipe and gas pipe connected to the same municipal main pipe have been renovated at the same time. Why do faucets of the same brand of gas water heaters occur differently after encountering different brands of gas water heaters? Is it because there are problems with the air pressure and water pressure of Mr. Wan’s parents’ home, or is there a quality problem with this "Wanjiale" gas water heater itself?
After a control variable test, the reporter and Mr. Wan reported the results of the test just now to the official after-sales service of "Wanjiale". A repairman from the other party said that the machine is a constant temperature machine. If there is no problem after the air pressure and water pressure data are detected, it may explain the problem of the water heater itself.
So, is it a problem with water pressure or air pressure, or is it a problem with this "Wanjiale" water heater itself? In order to find the answer, the reporter invited staff from Nanchang Gas Company to conduct on-site inspection of the air pressure at Mr. Wan’s parents’ home. It was found that the air pressure at Mr. Wan’s parents’ home was 2900Pa and the lowest was nearly 900Pa, while the normal pressure was 2000Pa. The high minus the low pressure was 2000Pa, and the test result was normal.
It is understood that the gas type of this "Wanjiale" water heater is natural gas-12T. According to the product specifications and component names indicated in the instruction manual, the gas rated pressure of natural gas 12T is 2000Pa. Therefore, the static pressure 2000Pa detected on site meets the gas rated pressure requirements.
Then the staff conducted dynamic ignition pressure detection. The test results showed that the gas pressure at Mr. Wan’s parents’ home met the requirements and the gas supply was stable. So, is there a problem with water pressure?
Then, a staff member of Jiangxi Hongcheng Environmental Co., Ltd. told reporters that the water pressure they measured on site was 0.25MPa, which was a normal pressure. It is also said that from the table, the pressure is stable and can be supplied to the 8th floor.
air pressure and water pressure are normal and stable. Consumers are calling for "Wanjiale": Be responsible for the problems of the product itself!
From the body nameplate of this "Wanjiale" gas water heater, the applicable water pressure is 0.02-0.8MPa. Obviously, the test pressure of 0.25MPa is fully in line with the requirements. After some testing, consumers are more convinced that the inability to control the water temperature is not a problem of air pressure and water pressure; then, why do the "air pressure" and "water pressure" marks of this water heater flash an alarm for normal and stable air pressure and water pressure?
htmlMr. 60,000 hopes that "Wanjiale" can find out the faults and problems of its own products, provide good service to customers, and not shirk responsibility. At present, consumer Mr. Wan has complained about the problem to the headquarters of "Wanjiale" and the market supervision department. The reporter of "Urban Site" will continue to pay attention to the latest progress in this matter.
