Step 2: Drain the water from the water heater, unscrew the sewage outlet and clean the water. If your water heater has not been washed for a long time, congratulations, you won't want to use your water heater for a long time.
Because the water that finally flows out is turbid, large pieces of scale fall off! Step 3: Clean the water tank in the water heater until the water in the water heater is drained, connect the hose (usually blue end) of the cold water pipe to the hot water outlet of the water heater, then open the cold water valve and flush the water tank in the water heater with water until the water becomes clear. Note: Many people say that water heaters can't be washed casually. What if it breaks down? The above method is only simple cleaning, which will wash away the dirt and scale in the water heater, save the extra electricity fee brought by scale, bring us clean bath water and have no influence on the water heater. Step 4: replace the magnesium rod water heater and clean it once every two years, not too often. If you really feel that you can't get started, please ask the master to go to the door for deep cleaning and replace the magnesium rod in the water heater by the way. So, what is magnesium rod and why should it be replaced? General household water heaters are equipped with magnesium rods to protect water tanks from corrosion. After a period of use, magnesium rods will be surrounded by impurities such as scale. If they are not replaced in time, they will corrode the water tank and shorten the service life of the water heater. Generally, the door-to-door service is about 50 yuan. If the master changes a magnesium rod, he will probably add about 50 yuan.
Sometimes some water heater manufacturers even offer free replacement of magnesium rods. You can also buy better magnesium rods online. The size of magnesium rod should be selected according to the volume of water heater and the diameter of sewage outlet. It's too big to hold, around 20 yuan, much cheaper than the master's own.
Energy saving and emission reduction is the development direction advocated by the state, and products with less energy consumption will be a development direction in the future. As low energy consumption products, solar water heaters and air energy water heaters have a good development momentum. However, due to some limitations of the product itself, the product has certain limitations in meeting the needs of consumers, so the comprehensive utilization of energy has become another direction for the development of water heaters. The water heater evaluation network believes that solar water heaters and air energy water heaters, as new energy products, are showing a strong development momentum. The two categories have rapidly expanded the market because of their unique performance and have a strong response among consumers.
In the solar water heater market, 2009, 20 10 and 20 1 1 were three years of ups and downs. In 2009, under the strong promotion of the policy of home appliances going to the countryside, the solar water heater industry ushered in the long-awaited rapid development. However, the solar water heater enterprises immersed in the joy of great development for a short time found that with the growth of home appliances going to the countryside, the market competition became more and more fierce, and the industry growth rate slowed down obviously in 20 10. By 20 1 1 year, under the background of global economic depression and a series of domestic policies, solar water heaters, which are already in the early stage of development, are experiencing the cold winter in the market, just like many household appliances.
With the improvement of people's living standards, people have higher and higher requirements for the comfort of family life. The various electrical products that followed facilitated human life and occupied a lot of space. Because of this, more and more multifunctional electrical appliances have entered people's lives. Water heaters are also undergoing different generations of development:
