1. Electric water heater.

What are the precautions when making Mori use it carefully?

1. When using the electric water heater, the power indicator light is on, indicating that the electric heating is on, and when the water temperature reaches the set value, the indicator light goes off, indicating that the power supply is cut off. The indicator light turns on and off, indicating that it is automatically keeping warm.

2. Before using the electric water heater, it should be filled with water, and then heated by electricity, and it can be used after preheating. If you suddenly encounter a drop in water pressure or a sudden water stop during use, it is best to turn off the power.

3. The temperature conditioner of the electric water heater has a water temperature mark scale, and the water temperature of the water heater will adhere to the temperature set in the gear indication by aligning the temperature adjustment knob at a certain mark. When using, it is best to let the water spill out to test the actual water temperature and then shower to avoid scalding due to the high water temperature.

3. When putting on the water, the water outlet must be opened, and the air in the inner tank can be completely discharged before checking whether the water is filled with this base. When the valve is just opened, do not turn the water outlet direction towards the human body to avoid safety accidents.

4. If you do not use the water heater for a long time, try to turn off the water heater, otherwise it will not save energy and greatly reduce the life of the water heater. If conditions permit, try to inspect the water heater once a year, mainly to check the heating status, the sensitivity of the key fingers, whether the drain valve is in good condition, and the electrical pipelines and brackets should also be carefully checked.

Purchasing. Tips.

1. Capacity. One of the most important parameters when buying an electric water heater is the capacity, which mainly considers the household size and the amount of hot water used. An electric water heater with a volume of 30-40 liters is suitable for 3 to 4 people to bathe continuously, and the capacity is selected according to the size of the family and bathing habits, so as not to cause waste.

2. Liner. The inner liner of the electric water heater is the key to the quality of the electric water heater, and the service life of the inner tank of the water heater is mainly determined by the material of the inner tank and the anti-corrosion technology of the inner tank of the manufacturer. At present, the inner tank of electric water heater can be roughly divided into three types: stainless steel inner tank, enamel inner tank and galvanized inner tank.

3. Energy saving. Energy-saving technology is another major criterion for measuring the energy efficiency of electric water heaters. In terms of energy saving, the most prominent technologies include intelligent reservation, self-learning heating, medium temperature insulation, layered heating, night electricity technology, etc., as long as these energy-saving technologies are used reasonably, they can greatly reduce the cost of use and make bathing life more pleasant.

What problems do you need to pay attention to when buying a water heater?

1. First, we choose electric water heaters, to choose through several channels, the first channel is the network to buy and choose, the other channel is the physical store purchase, it is recommended that you combine to compare, choose the most preferential as well.

2. Second, the purchase of electric water heaters, we must pay attention to the choice of function, we must know that the biggest selling point of an electric water heater is function, so if we want to buy a suitable electric water heater, we must eliminate unnecessary functions, such as power-saving function, temperature self-regulation, in fact, there is no practical use at all.

3. Third, when we choose an electric water heater, we should also pay attention to the reputation of the water heater, which is very important, you can ask the surrounding neighbors and friends, you can also check the evaluation of the electric water heater on the Internet, and choose Zheng Nahao in combination with everyone's opinions.

4. Fourth, when choosing an electric water heater, we should pay attention to the inner tank of the electric water heater, the biggest function of an electric water heater is to ensure the quality of the inner tank, we must check whether the inner tank is made of titanium alloy, and also check the thickness of the inner tank.

5. Fifth, the heating pipe of the electric water heater is very important, the quality of the directly affects your use, it is recommended that you should pay more attention to the power of the electric heating pipe, to see if it is suitable for your family, and a key point is to pay attention to the electrical performance of the electric heating pipe.

6, the first. 6. What kind of electric water heater is not polluting? In fact, this truth is very simple, magnesium is actually the most environmentally friendly metal material, and it will not cause any harm to the human body, nor does it have any toxins and ***, so it is the best choice to make magnesium rods to protect the inner tank.

7, the first. 7. When buying an electric water heater, we should also pay attention to the various joints of the electric water heater, which is also very critical for the electric water heater.

The above are the things you need to pay attention to when buying a water heater. When we buy a water heater, we must first determine which style of water heater we need to buy.

Most of the water heaters sold in specialty stores are relatively good, and we should also look at the power and capacity of the water heater when we choose. The power consumption of water heaters of different power is different, if you want to save electricity, you can choose some water heaters with low power.

You can get it for free

In a "storage type" electric water heater, it is the inner tank of the water heater that directly affects its service life.

Since the inner tank of the electric water heater is in direct contact with the water source for a long time, and it needs to withstand a certain amount of water pressure, it is required that the inner tank of the water heater must have good corrosion resistance and pressure-bearing capacity.

The corrosion resistance of the inner tank is currently the leading one in the world is the "electrostatic dry powder coating technology", through which the inner tank enamel coating can be made more uniform and tighter, and the coating is integrated with the inner tank, with strong corrosion resistance and water pressure impact resistance, which greatly prolongs the service life of the inner tank.

The pressure-bearing capacity of the inner tank The pressure-bearing capacity of the inner tank depends on the thickness of the metal material of the inner tank, which can be known by asking the factory when purchasing.

Insulation material for water heaters.

There is a direct relationship between the power consumption of the electric water heater and the insulation layer, and the better the insulation material, the higher the thermal efficiency. At present, manufacturers with better technology have adopted polyurethane on-site foaming, which has high foaming strength, high density and good thermal insulation effect.

Necessary protective measures.

Over-temperature protection When the water heater fails and the heating exceeds the limit temperature, the protector can automatically cut off the circuit and stop heating.

Anti-dry boiling protection If there is no water in the water heater and the heating pipe is dry, the system can automatically cut off the power supply of the heating pipe to protect the heating pipe and the inner tank from damage.

Leakage protection Efficient and sensitive leakage protection system can ensure the safety of use.

Pressure relief protection valve When the pressure in the inner tank of the water heater exceeds the standard (greater than 8kg), the pressure can be safely relieved to ensure that the pressure in the inner tank is within a safe range.

Precautions during the use of storage type electric water heaters.

1.When the electric water heater is turned on for the first time, it must be filled with water in the inner tank of the water heater, and the specific operation is to open the mixing valve and hit the valve handle all towards the hot water end until there is a uniform flow of water at the shower or water outlet.

2.Electric water heaters are generally equipped with magnesium rods, which are used to protect the inner tank of the water heater. Magnesium rods are a consumable material, and their lifespan varies depending on the quality of water in each region.

After a period of use in the water heater (generally 2 to 3 years), the magnesium rod will be naturally depleted, and then the magnesium rod needs to be replaced. The specific situation can also be known by consulting the manufacturer's after-sales service.

3.For a water heater of the same volume, the higher the heating temperature setting, the greater the hot water output.

4.After the hot water in the water heater is exhausted in one go, it may take some time for the water heater to heat up the re-water inside to the set temperature.

Instantaneous "instantaneous" electric water heaters should be paid attention to when purchasing:

It is best to buy products with better quality and safety guarantees produced by big brand manufacturers. In addition, it is necessary to consider whether the power supply capacity of the home can meet the needs, and the input power of the general "instantaneous" electric water heater is about 7000 20000W, which has higher requirements for the power supply capacity of the user's home.
