Speaking of the water heater, I believe that everyone will not be unfamiliar. Basically, every household has a living standard. But it is not clear what you think about the type of water heater. There are many types of it, such as our water storage type electric water heater , which can store water temporarily or for a long time. If you don't know the water storage type electric water heater , you will come with the decoration house Xiaobian. Let's see.
1. Storage environment requirements for water storage type electric water heaters
1, home power supply standards
According to national standards, the power supply for household electrical equipment should be single-phase three-wire 50 Hz 220 volt AC. The three wires of the power supply—the fire wire, the neutral wire, and the ground wire are connected correctly and conform to the external mark. The grounding is good, the insulation protection is intact, and the wire diameter is sufficient to meet the capacity load requirement. The allowable deviation of the supply voltage in the national power quality is -10% to 7%, which is between 198 volts and 235 volts according to the standard voltage of 220 volts. For electric water heater products, the deviation is correspondingly expanded to -15% to 10%, that is, between 187 volts and 242 volts. In areas where the electricity load is relatively concentrated, it should be expanded as appropriate.
2, protection requirements
The household meter load should not exceed the standard. It is best to have an air protection switch. At least the fuse protector—such as the fuse (wire) and the fuse (wire) should not exceed the limit value. The water storage type electric water heater should be provided with a separate power supply line. Do not share a power line with other high-power appliances (such as Yuba, heater, electric heater) (note that it is connected from the meter, not from the wall socket. It is even more difficult to connect from the middle. Separate protection devices such as leakage, overload, and overcurrent are provided. The current level of protection should not be greater than twice the rated current of a single appliance.
3, power outlets and extension cords
The electrical outlets required for electrical appliances should be configured as required. According to the requirements of national standards, single-phase three-wire (hole) socket, the left end of the socket is N pole, connected to the zero line; the right end is the L pole, the phase (fire) line is connected; the end with the ground symbol at the upper end should be the grounding wire, and must not be interchanged. The socket should be matched with the electric water heater plug, preferably 16 amps, especially the rated power consumption of the electric water heater is more than 2000 watt hours. The socket is preferably waterproof and has a casing protection to prevent water and steam from entering the connection gap between the plug and the socket. The socket should be placed as far as possible. If it is installed on walls and other objects, it should be kept away from the water source or the nozzle. It is best not to directly contact the water and water in the bather and bath.
4, the power wiring can not be too thin
The power should be 50% or more larger than the rated maximum power of the appliance, and the current should be 6 amps to 10 amps (power 1320 watts to 2200 watts). The cross-sectional area of ​​the power cord should be ≥1 mm 2 ; the current should be 10 amps to 16 amps. (power 2200 watts to 3520 watts), the power line cross-sectional area ≥ 1.5 square millimeters; current is 16 amps to 25 amps (power 3520 watts to 5500 watts), the power line cross-sectional area ≥ 2.5 square millimeters. The wire sheath should be waterproof and wear-resistant, and the wire ends and joints have sufficient and good connection. When used for a long time, you can easily judge without holding the temperature.
5, consumers must not match their own power leads
Installation and maintenance professionals are also not able to adapt or modify the power leads themselves. The modification and mating of the power cord must be carried out by a professional who has been trained to have an electrician's certificate. The electrician's work is a special operation and must be certified.
Second, the advantages and disadvantages of water storage type electric water heaters
Advantages: high safety performance and clean energy. Can supply water in multiple ways. It can be used for showers, baths, laundry and washing. Installation is also simple and easy to use.
Disadvantages: Generally, the volume is large, and it needs to be preheated before use. It is not possible to continuously use the amount of water exceeding the rated capacity. If there are many families, the bath must wait in the middle. In addition, the hot water that has not been used up after washing will slowly cool down, causing waste. The water temperature is high in heating temperature, easy to scale, and the dirt cleaning is troublesome, which is unclear and affects the life of the heater.
Water heaters are electrical products. We must not use the tools that use electricity. We must remember that the installation environment of storage water heaters must be used when we install the water heater again. In general, any kind of water heater is both good and bad. The same is true for storage water heaters. When we choose, we should first consider which one we prefer. For more exciting content, please stay tuned to the home of the decoration.

Whether it's renting or our own house, our indoor use area is always limited, each place has its own specific purpose, there is no extra space to put anything. However, for the convenience of life, we always need to be equipped with all kinds of equipment. For example, adults need a desk, children need a learning desk, but too many tables at home will be very crowded. If you have a Sit Stand Desk , you can perfectly solve this problem, that is, the Adjustable Standing Desk.
Height Adjustable Table can be raised and lowered to meet the needs of different heights. In addition, the Height Adjustable Standing Desks have four height memory keys, which correspond to four requirements and can be adjusted to the appropriate position with one key.
