An electric water heater is a common household appliance that can provide us with comfortable hot water and allow us to enjoy the pleasure of bathing at home. However, there are many types of electric water heaters with complex parameters. We often choose between them in the market, and we don't know which one is more suitable for us, today we will take a look at this article: Cost-effective Electric Water Heater Analysis Purchase Guide!
1. Confirm the type of electric water heater.
Electric water heaters can be divided into the following types according to the heating method and water storage method: storage electric water heater and instantaneous electric water heater.
1.Storage type electric water heater: This is the most common type, it stores heated hot water through a storage tank, which can be released directly when in use. It has the advantage of providing hot water with a stable and constant temperature, which is suitable for multiple people. The disadvantage is that it takes up a lot of space, needs to be heated in advance, and has a limited thermal insulation effect.
2.Instantaneous electric water heater: Uses a heating element to achieve rapid heating, ready to use when in use. The advantages are space-saving, energy-saving and eco-friendly, and there is no need to worry about bacteria. The disadvantage is that the heating speed is limited by power and flow, and may not be able to meet the needs of high temperature and large flow. It is suitable for kitchens that do not need to boil hot water for a long time.
2: The capacity of the electric water heater.
The capacity of an electric water heater refers to the maximum amount of water that can be stored in a storage tank or pre-heated water tank. Choosing the right capacity is an important factor in ensuring water comfort and energy savings.
Generally speaking, the higher the capacity, the higher the power consumption, but the more water consumption is provided. The smaller the capacity, the lower the power consumption, but frequent use of hot water may result in insufficient water or frequent heating. Secondly, some electric water heaters are equipped with dynamic heating technology or dynamic capacity increase technology, that is, burning while in use, and ensuring the capacity of hot water through continuous heating.
Finally, when choosing capacity, factors such as household size, water consumption, bathing habits, seasonal changes, etc., can be taken into account.
Three: the inner tank material of the electric water heater.
The inner liner material of the electric water heater mainly refers to the material used inside the water storage tank or pre-hot water tank. The inner tank is the core of the electric water heater, which determines the performance and service life of the electric water heater. The liner materials on the market are broadly divided into two categories: stainless steel liners and enamel liners.
Stainless steel liner: the best performance, the longest service life, high temperature resistance, corrosion resistance, and not easy to rust. However, welding is difficult, and water leakage in the inner tank often starts with the welding wire. The inner liner of the high-quality electric water heater adopts the deep-drawing integrated molding process. No welding, no gaps, can eliminate the hidden danger of water leakage.
Enamel liner: It is the most mainstream liner material at present. It does not rust and does not scale easily. To put it simply, the enamel process is the application of liquid glaze layer by layer on the surface of the metal. The glaze and construction technology are different, so the blue diamond liner, gold liner, etc., different grades of enamel liner determine the durability of the enamel liner, such as anti-corrosion, anti-rust, anti-scale, etc.
Four: the brand of electric water heater
In terms of brands, there are many well-known brands of electric water heaters on the market. For example: Haier, Midea, Wanhe, Smith, Casarte, Vantage, etc. These brands have a certain market reputation and after-sales service guarantee, but the performance of the product will also be different. Therefore, we need to choose the right brand and model for ourselves according to our needs and budget.
Haier: As a well-known domestic home appliance brand, Haier has participated in the drafting of a number of national standards for electric water heaters. Haier electric water heaters have many styles, rich functions and strong technical force. Haier took the lead in launching the "anti-electric wall" technology, which has a relatively high level of security protection.
Midea: Like Haier, it is a powerful household appliance brand, and its electric water heaters have always been very popular with users. The equipment has strong materials, reliable workmanship, and rich safety technology. In addition to the anti-electric wall, it also has the functions of automatic power-off, anti-dry burning, and anti-leakage. The quality is quite reliable.
Wanhe: As a relatively successful water heater brand in domestic electrical appliances, Wanhe's electric water heater still has a good reputation. They are relatively compact, fully functional and have a high level of safety. Moreover, it has always been more affordable.
Five: Household electric water heater hot-selling style recommendation:
The first one: Midea household electric water heater
This Midea electric water heater, with a large capacity of 60 liters, first-class energy efficiency, and a high power of 3200W, creates a comfortable, convenient and energy-saving household water environment for you. The 60-liter flat drum design has a large capacity to meet the needs of multiple people in the family to use hot water at the same time. Double-gallon water storage is another highlight of Midea's electric water heaters. Six-stage filtration technology can also make water purer, making your home water healthier and safer.
The second: Casarte household electric water heater
Casarte household electric water heater has a large capacity of 60L and a width of only 70cm, and the installation position is very flexible. It uses an iridium seamless double liner. The entire liner adopts an integrated seamless process. It has a built-in FOF long-term anti-scaling module. The anti-scale rate can even reach 955%。It can also be fully implemented at a later stage. No cleaning is required.
Double 3000W independent inner tank, the water volume can be increased by 10 times. And equipped with a maternal and infant filtration system, with excellent water purification and antibacterial effect.
The third: Haier household electric water heater
Haier household electric water heater has a large capacity of 60L, which saves space compared to ordinary 50L electric water heaters. The compact body has no sense of oppression, making it especially suitable for small bathrooms. It features a separate double inner pot and a double heating rod. The power of each heating rod can reach 3000W, and the heating speed is very fast. There are three modes: single tube washing, comfort washing, and waterfall washing. When washing, a single tube washing method can be used, which is fast heating, energy-saving and water-saving.
The fourth: Wanhe household electric water heater
Wanhe electric water heater supports one-key automatic shutdown mode. When the heating reaches the set temperature, the power is automatically cut off to protect the safety of bathing, without the need to plug and unplug repeatedly. Extend the anti-electric wall, which increases the resistance between people and water. In the event of a leakage, the voltage applied to the human body is less than 5V, which is far lower than the safe voltage that the human body can withstand.
