AO Smith water heater suspected of hot water "short"

A 80L large capacity water heater, just spent a year, now out of hot water time, even a person to bathe is not enough. This kind of thing, who met all feel vexed, also be questioned by consumers. Recently, the user of Ms. Wang complained to reporters home AO Smith water heater temperature is very fast, can be repeated to the after-sale consultation, and dealers after maintenance, have not been well resolved. Reporter found that the use of AO Smith water heater short time complaints in recent years is not a case. But the explanation of its customer service is that the working principle is not changed, and the temperature falling speed is reasonable range. In the end 80L water heater hot water supply time should be how long, is not the factory said reasonable? At present, the water heater industry does not have the corresponding specification about the water quantity and the effluent time by the different of the pipeline thickness, the shower size and the hydraulic pressure when the household is installed. The AO Smith water heater at the home of the citizen, Ms. Wang, has been a bit depressing in "work" time since about December last year. "It's cold in winter, especially if you want to take a little more hot water and be comfortable." Ms Wang reluctantly told reporters, but the reality is that if you do not quickly wash the bath, it is necessary to wash cold water bath, let alone a down-to-earth hot bath. Ms. Wang's home purchase of the 80L capacity of AO Smith water heater, six months ago began to appear hot water can not meet the normal use of the situation. She told reporters, buy the time in order to meet the use of a three, so special bought 80L large capacity. It never occurred to me that the whole family would have to wait for a bath. According to Ms. Wang, just started to buy water heaters in a few months, only to the water heater rated temperature of 60 ℃, you can meet the normal use. But now, even if the temperature to 75 ℃, but barely enough for a person's normal use. After discovering that the water heater does not come in hot water, Ms. Wang has repeatedly called AO Smith Customer service staff, the relevant maintenance director told Ms. Wang, because the water temperature is low in winter, so first of all to the water heater water temperature set to 75 ℃ high temperature, in addition, before using the water heater mode adjustment to "the whole bile speed hot" and "instant heating", This will ensure normal use. Ms. Wang adjusted for the staff, the problem has not improved. Ms. Wang told reporters that she has repeatedly called customer service around 5-6 times, but the relevant maintenance personnel to "winter temperature is low, this situation is normal" for, never door-to-door service. Through the spring and autumn months, until now such a hot day, the water heater is not "better", still can only just enough to bathe. Ms Wong's encounter is not a case. Reporter input "Smith water heater in the end how long to wash" after the discovery from 2009 to date, there are dozens of water heaters to reflect the short hot water time "complaints", and the basic focus on 80L products. "Even scrub time is not, soap a dozen, rushed to run out, hot water only more than 10 minutes." "Netizens reflect, also have after the door-to-door inspection, after the sale of the saying is normal, but if normal, how enough to bathe?" Also has the Netizen exchange to continue the hot water experience, may let the Smith 80L can wash about 45 minutes. "such as water heater temperature displayAfter 75℃, continue to power for more than half an hour and then go in to wash. Personally feel that Smith's temperature is problematic, just start to show 75 ℃ does not mean that the entire tank has reached 75 ℃. There is the home of the shower to buy water-saving type. "User tips. Reporter experiment in the end 80L of water heaters, hot water effluent time in about 15 minutes, is not as the manufacturer said, belong to normal, other water heaters are what the situation, the reporter chose Ao Smith 80L and a domestic brand 40L mechanical version of the product made a comparison. Shower size: diameter 8cm ordinary round shower The actual temperature at the beginning of the experiment: 75 ℃ Reporter will adjust the water temperature to 40 ℃ body feeling comfortable temperature began to continue to water, 8 minutes later, the temperature began to decline. At this time the water heater shows the actual temperature is 73 ℃, the actual temperature of the effluent is 38 ℃. Press to maintain hot water regulator valve does not move, continue to effluent, 2 minutes later, the actual temperature of the water heater began to decline rapidly. On average 15 seconds down 1 degrees, when the actual temperature of the effluent fell to 36 ℃. Then adjust the valve, the water temperature return to 40 ℃ comfortable temperature continue to work, 1 minutes later, the water temperature again significantly reduced, 1 minutes later to 35 ℃, at this time the body feel the water temperature has been cooling. The water heater shows that the water temperature drops to 57 ℃ and the hot water shows all turned orange. Reporters continue to regulate the heat of water, to the beginning of the experiment 13 minutes, the water temperature has not reached the body feel comfortable 40 ℃, and began to fall below 35 degrees. The water heater shows the actual water temperature is 43 ℃, at this time no normal use, the experiment is over. Total length of experiment: 13 minutes Shower Size: diameter 8cm ordinary round shower experiment at the beginning of the actual temperature: 75 ℃ Reporter will adjust the water temperature to 38℃-40℃ body feeling comfortable temperature, continuous discharge. 5 minutes or so, the water heater heating indicator light, 8 minutes later, the water temperature does not appear to fall, the body feel comfortable. During the whole testing process, the control handle under the shower is always located in the middle of hot and cold water, without moving position. After 18 minutes, the water temperature is normal, the test is 37 ℃, the heating indicator is continuously on. After 20 minutes, the temperature was slightly reduced to 36.73 ℃. Results: 20 minutes after the bath is still not affected by a reporter to visit the hot water outlet time by the shower and other factors influence subsequently, the reporter visited the two major home appliances store water heater area, in addition to a few customers, 35 brand of water heater sales area are no sales staff, including AO Smith. In a home appliance store, other brand sales told reporters, come to catch up with sales. Reporters to other brands of sales staff asked 80L water heaters hot water, they all said 15 minutes of time is certainly not normal. A domestic brand water heater shopping guide told reporters, under normal circumstances, do not use a larger disk shower, bath water when the length should be in 40 minutes, to the summer will be longer, to ensure that two people a normal bath. The reporter tried to find out the relevant text about the time of water in the heater manual, and the salesman said that none of the water heaters would write this. Because the consumer family environment and the choice of bathroom items, have a direct impact on the length of hot water. LadyPeople told reporters that after the water heater problems, after-sales service in the phone to give them the use of guidance, including the water temperature to the highest, the use of "whole bile speed" and so on, and said that the hot water lasted more than 15 minutes, belong to normal. Ms. Wang said that when buying a water heater for a family can use, now the situation and to buy a small no difference, but to spend a lot of money. Regarding Ms. Wang's question, the reporter two times in the consumer identity telephone interview A0 Smith Service hotline, the customer service personnel inquired the reporter's use method and so on the question, all said 80L water heater, hot water time 15-20 minutes is no problem, most of the water heaters are like this. The reporter suggested that the family had used the same brand products of 60L, but did not appear such a problem, because of product design or other problems? One customer service said that 60L should not have 80L products more hot water. Another customer service told reporters that the use of the machine is the same principle, as to why this situation can not be explained. Reporter found in the interview, the store AO Smith water heater New product leaflet, the factory phones are wiped black handwriting, can not see the phone. Then the reporter through to find the switchboard number, but many times to call the switchboard busy. In the interview process, whether it is customer service, technical personnel, or store sales staff, when heard the reporter reflected the question, the first question is: "You use the flower sprinkle how big?" "Then there was the size of the access pipe, the water pressure, and so on, until the final mention of the product." Of course, the reporter interviewed down, also know that the original use of water heaters, external conditions are very important. But these, in the manual, the installation process has not been mentioned. On the electric water heater industry standards are not many, at present can be reflected in the product is the manufacturers need to mark hot water output. Regardless of the quality of the product itself, whether the design is perfect, only from the later use of the process, as a consumer of "technical support", manufacturers at least in the installation process, it is necessary to inform consumers on the use of products have an impact on external factors, to consumers a guide to installation. Do not have a problem in the time, the consumer doubt repeatedly, "never heard of the shower can not be too big, no one said the water pipe should be more coarse, the intake valve should be adjusted to the largest." "It is better to have someone to tell in advance, in the presence of problems, so that consumers have a spectrum, not a product problem, the problem in the end where?" Hot water heater output rate: Refers to the nominal conditions of the actual hot water output and rated capacity ratio. The difference lies in: for example, 60L water heaters, the output rate of 60%, the hot water output of 36L, the output rate of 70%, the hot water output of 42L, it indirectly reflects the remaining hot water can not be discharged how small. Hot water output rate is tested under the rated conditions, not to say that the actual use of the user 60L water heater output rate of 60%, its hot water can only output 36L, the general bath can be output of hot water will exceed the water heater capacity.
