How to use an electric water heater

1. When using an electric water heater, turn on the power and the indicator light will light up, indicating that it is electrically heated. When the water temperature reaches the set value, the indicator light will go out, indicating that the power is cut off. The indicator light will turn on and off from time to time, indicating that it is automatically keeping warm.

2. The electric water heater (storage type) must be filled with water first, then powered on for heating, and can be used after preheating. If the water pressure drops or the water supply is suddenly cut off, it is best to turn off the power supply.

3. Electric water heaters are equipped with faucets and reflux devices. Usually "blue" indicates cold water and "red" indicates hot water. When in use, turn on the "red" faucet and hot water will flow out. If the water temperature is too high, you can turn on the "blue" faucet at the same time and adjust the water volume to enjoy hot water at the right temperature.

4. The temperature regulator of the electric water heater has water temperature marking scales, such as "I", "Ⅱ", "Ⅲ" or English and Arabic numerals to indicate the low, medium and high water temperature adjustment positions. When the temperature adjustment knob is aligned with a certain mark, the water temperature of the water heater will reach the temperature set at the gear indication. When using, let the water spill out first to test the actual water temperature to avoid excessive water temperature and burns to the skin.

5. When filling the tank with water, the water outlet must be opened, and the air in the tank must be completely discharged before checking whether the water is full.

6. After eliminating the problem, the power supply must be cut off first.

7. When used as a blocking device, the water inlet valve must be in the open state during heating.

8. When you just open the valve, do not direct the water towards the human body.

The working principle of the electric water heater is to apply the reverse Carnot principle, by absorbing a large amount of low-temperature heat energy in the air, compressing it into high-temperature heat energy through the compressor, and transferring it to the water tank to heat the water. In addition, when using an electric water heater, you need to pay attention to the various signs on the surface.

How to clean an electric water heater

1. First of all, the water heater should be cleaned every 2 to 3 years. Before cleaning the water heater, you should first cut off the power supply and water supply, drain the water in the water heater, and open the drain outlet.

2. Take out the magnesium rod inside and check whether it needs to be replaced. Prepare the descaling powder and mix it according to the proportion. Pour the prepared water solution into the water tank and soak it.

3. The magnesium rod also needs to be soaked for about twenty minutes. Drain the water in the water tank and rinse with plenty of clean water.

What is the appropriate power for an electric water heater?

1. Storage type electric water heater: Its power is usually around 1500 watts, which can be supported by most household lines. It is usually the standard configuration of household electric water heaters. Its disadvantage is that it takes a long time to heat up due to its large size.

2. Instantaneous electric water heater: Its power is generally around 2500 watts. This type of water heater has a very fast heating speed. Usually it only takes 10 minutes to heat dozens of liters of water to 80 to 90 degrees. The water behind can continuously supply hot water.

3. Instant electric water heater: Its power is generally around 5000 watts. It is also used in villas. Its power can be as high as more than 10 kilowatts. Although its power is very high, its water output speed is very fast. It can produce hot water in a few seconds. This kind of water heater is not suitable for ordinary household circuits. If you really want to install this kind of electric water heater, you need to adjust the circuit at home.
