with the continuous development of science and technology, kitchen electrical products begin to appear frequently in our lives. What should we pay attention to in the daily use of household water heaters? Next, let's learn about the relevant introduction of household water heaters

how to use domestic water heaters safely

1. Professionals should install water heaters according to regulations

2. In order to prevent scalding, you can open the cold water valve first, and then the hot water valve: when closing, close the hot water valve first, and then the cold water valve. When using, let the water sprinkle out and try out the actual water temperature before taking a shower, so as to prevent the skin from being scalded by too high water temperature

3. When the water valve is opened and there is no water, the power supply should be turned off immediately to prevent damage caused by using the electric water heater under the condition of flowing water due to water circuit failure

4. Avoid damaging the electric water heater due to the high temperature of the outlet caused by the size of the water inlet

5. It is strictly forbidden to install valves at the water inlet and outlet at the same time

6. When using the water heater in the frozen area, keep the water in the water heater at a certain temperature, and it will not freeze. Otherwise, the electric water heater will be damaged. 7. If the water pressure or battery is too low, it should be suspended

precautions for household water heater

1. When using the water heater, turn on the power and the indicator light is on, indicating that it is being powered on for heating; When the water temperature reaches the set value, the indicator light goes out, indicating that the power supply is cut off; When the indicator light is on and off, it means automatic heat preservation

2. The electric water heater should be filled with water first, and it is best to turn off the power supply in case of water source pressure drop or water cut-off

3. Electric water heaters are equipped with faucets and reflux devices, usually “ Blue ” Indicates cold water, “ Red ” Indicates hot water. On the temperature regulator of the electric water heater, there is a water temperature gauge to the scale, usually ‘ Ⅰ“、& ldquo; Ⅱ”、& ldquo; Ⅲ” Or signs in English and Arabic numerals indicate low, medium and high water temperature

cleaning of household water heater

inside the water heater, the hot water pipe orifice is high, about 2 cm away from the top of the liner, while the cold water pipe orifice is low, about 3 cm away from the bottom of the liner. When using the water heater at ordinary times, the cold water pipe is always filled with water, and the hot water is squeezed to the top by the cold water, and the water flows out along the hot water pipe, while the scale is deposited at the bottom of the inner tank and will not be discharged through the hot water pipe

light cleaning: do it yourself. It is suggested that the electric water heater should be cleaned by someone every three years and cleaned by yourself every six months. The cleaning steps are not complicated and can be completed by yourself. Unscrew the nut of the hot water port and block the hot water port to prevent the water from flowing out of the water heater. At the same time, unscrew the nut of the cold water port, connect the hose (sprinkler pipe) to drain water until there is no water flowing out of the cold water port. For a 50L water heater, drain water for about 1 hour

next, remove the hose connected to the cold water port, connect one end of the hose to the hot water port and the other end to the faucet, turn on the faucet to fill water for 1 minute, block the cold water port, let the cold water stay in the inner tank for a while, then turn on the cold water port to drain, and repeat several times until the discharged water is clean

finally, screw on the nuts of the cold water port and the hot water port, open the triangle valve, and turn on the hot water of the water heater faucet. After the water flows out, close it. Cleaning precautions before cleaning, the water temperature of the water heater should be below 50 ℃. Such water temperature can be directly discharged to the sewer pipe without affecting the pipe. During cleaning, if the water heater has a drain outlet, it can be opened at the same time, because the drain outlet is lower than the cold water outlet, and the sewage discharge is more thorough

the above is the relevant content of household water heater. I hope it can help you. More decoration information is available. Please look forward to it
