As a daily household appliance, almost every household has a water heater. However, many people may not know that this "guy" who cleans himself every day needs to be cleaned by itself. Recently, Jinjiang City Convenience Service Center has done a test to clean water heaters, and a group of cleaning charts has drawn attention.
test
The water heater uses a year and a half to clean out a few pots of dirty water.
A few days ago, Jinjiang City Convenience Service Center invited a professional master Wang, the test object is a water heater that only used for 1 year and 7 months. In household appliances, such use time is not long.
Magnesium rod for heating is covered with scale
Master Wang first cut off the power supply of the water heater, then opened the maintenance port on the side of the water heater and took out the heated magnesium rod. He said that this step must be dismantled by professional maintenance personnel. The reporter found that there is a lot of scale on the heating rod. Then Master Wang closes the triangular valve, unscrews the nut of the cold water port and the hot water port, and connects a hose to the cold water port of the water heater. The water in the water heater flows out through the pipe.
a large amount of sewage flows out of the water heater
"Hey, there is no dirt in the water..." said the onlookers. Master Wang replied, don't worry, look down.
There are a lot of dirty things in the water heater tank
After 30 minutes, the reporter saw that the water flowing out of the water heater gradually became black, accompanied by yellow dirt deposits, and there were more than half pots. Master Wang said that this is only the sewage at the bottom of the water heater tank. After he drained the water in the water heater, he began to clean the liner with clean water. After the first cleaning, the 30 cm diameter washbasin was filled with black water. It was not until the fourth wash that the water returned to clarity.
Doctor scale or water sputum that causes skin allergies is harmful
The reporter interviewed a number of citizens, most of whom said they had never cleaned the water heater at home. Ms. Wang said that the electric water heater suddenly malfunctioned at home last year. When the professional master repaired it, the master cleaned a lot of sediment and scale from the inner tank of the water heater. "In the past, I only knew that the air conditioner should be replaced with a filter. The original water heater has not been cleaned for a long time, and it will bring so much trouble." Ms. Zhang told reporters.
Is there any harm to the use of water heaters that have not been cleaned for many years? Dr. Zhang, a city dermatology prevention and treatment hospital, said that scale contains a variety of chemical components, long-term precipitation and accumulation of harmful substances in the water, may cause skin allergies; slime, microorganisms, bacteria In the long-term continuous update, alternating reactions will produce a lot of harmful substances, can cause a variety of skin diseases, some women, children after bathing, will feel itchy skin and red spots. He particularly reminded that many people directly use the water in the water heater to gargle, this behavior is very harmful.
Suggest
Deep cleaning once every three years
So, how long does it take for the water heater to be cleaned? How to clean it properly?
Master Wang introduced that in general, storage water heaters need to be thoroughly cleaned every three years. For gas water heaters, the gas carbon accumulation point must be removed first. Otherwise, there will be red flame deflagration when burning, and there will be incomplete combustion. After the electric water heater is not used for a period of time, the water will accumulate for a long time, and pollutants will be generated. The temperature control and electric heating pipes will also have copper rust. If no attention is paid, the copper rust will irritate the skin and cause illness.
Some readers consulted, since the inner tank has dirt, why is the water flowing out during the bathing? Master Wang said that the internal structure of the water heater is the same, the hot water nozzle is about 2 cm from the top in the high place, and the cold water pipe The mouth is at a low position, about 3 cm from the bottom of the liner. When the water heater is used normally, the cold water pipe is always in the water. The hot water is squeezed to the top by the cold water, and the water is discharged along the hot water pipe, and the scale is deposited on the bottom of the inner tank and is not discharged through the hot water pipe.
The reporter learned that even the "no-clean" water heater on the market must be cleaned regularly, otherwise it will be dirty. In addition, there is also a problem of water inside the water heater. Sometimes, when the water is stopped, it is often dirty, and the dirty water will automatically enter the water heater.
