How to choose an electric water heater?

Instant heating is more time-saving and electricity-saving than ordinary heating, and instant heating is recommended.

Brand: There are many brands of electric water heaters. Midea, Smith, Wan Jiale, Haier, Wanhe and ariston are all very good brands of electric water heaters.

When choosing water heaters, try to choose water heaters of big brands, and their quality will be relatively more guaranteed.

Here are some suggestions:

First, some tips for choosing an electric water heater-

Selection of inner container

The inner container of electric water heater is more important. At present, the inner container of electric water heater can be roughly divided into three grades: stainless steel inner container has the longest life. But the price of this electric water heater

Relatively high, suitable for relatively well-off families. The mid-range is an enamel liner, which is easy to drop porcelain. The relatively low-grade galvanized lining coated with cured resin has a short service life. because

Low manufacturing cost and low selling price.

Second, some tips for choosing electric water heaters-

Pay attention to safety performance

Electric water heater is a necessary household appliance, so safety performance should be paid attention to when choosing electric water heater. The electric water heater should be equipped with anti-dry-burning, anti-overtemperature and anti-overpressure devices, and consumed.

Products with large thickness of moisturizing layer and high density of thermal insulation materials should be selected, which can be compared and selected according to the manufacturer's product manual. ?

Third, some tips for choosing electric water heaters-

Selection of heat preservation effect

The power of electric water heater is an aspect that consumers have to consider, and the key to affect the power consumption of water heater is insulation effect, which should be considered emphatically when purchasing. Main factors affecting thermal insulation effect

The main factors are the thickness of insulation layer and the density of insulation materials. Consumers should try to choose products with large thickness of moisturizing layer and high density of insulation materials, and the book ratio can be defined according to the products of manufacturers.

According to the choice.

Fourth, some tips for choosing electric water heaters-

Selection of safe installation

Because the use of electric water heaters is related to the personal safety of consumers, we must pay attention to safety performance when choosing electric water heaters. Electric water heaters generally need makeup protection to prevent dry burning.

Combustion, anti-overtemperature, anti-overpressure installation, as well as leakage protection, waterless automatic disconnection and additional power-off indication functions. The rated pressure of the water heater liner is usually

0.75MPa (different models have different ratings). When the pressure in the tank with overpressure protection device reaches the rated value, the safety valve should be firmly and automatically opened for pressure relief, so as to

To ensure the safe installation of leakage protection, it is generally required that when the leakage current reaches 15mA, the power supply can be quickly cut off within 0. 1 sec. It is necessary to buy products with the Great Wall safety sign.

Extended data:

Electric water heater refers to a water heater that uses electricity as energy for heating. It is one of the three major water heaters alongside gas water heaters and solar water heaters. According to the heating power, electric water heaters can be divided into three types: storage type (also called volume type or heat storage type), namely hot type and fast heating type (also called semi-storage type).

Although the common quick-heating electric water heater and dual-mode electric water heater are similar in size, their internal structures are quite different. Compared with the water storage electric water heater, the quick-heating electric water heater is only smaller and more powerful, so the heating speed is indeed faster than the water storage electric water heater.

However, it can't be heated immediately in spring and autumn, and it needs preheating, that is, it needs to wait, while the dual-mode electric water heater can be heated immediately in spring, summer and autumn, that is, it can be heated immediately when it is turned on.
