Electric water heater purchase tips electric water heater installation precautions

Now the water heater is an indispensable household appliance for every family. No matter whether it is spring, autumn or winter, I believe that everyone no longer wants to go to the big bath to take a bath. In summer, the weather is hot, people are used to taking a bath every morning and evening; spring and autumn may be once a day; winter may be bathed three or four times a week. Electric water heaters , generally water storage type electric water heaters, that is, hot electric water heaters, and these two types of electric water heaters have their own different advantages and use characteristics, then what kind of electric water heaters are good? The following decoration home decoration network Xiaobian will take you to understand the purchase skills of electric water heaters and precautions during installation.

Optional tips for electric water heaters

The open type electric water heater is not resistant to pressure and cannot supply multiple waters at the same time; the enclosed electric water heater can withstand pressure and can supply multiple waters at the same time.

Advantages: It can adapt to any weather changes. Ordinary households can be installed and used directly. Most electric water heaters on the market today also have anti-shock devices. Electric water heaters have a better record of safety issues.

Disadvantages: It is bulky, takes up large indoor space, is easy to scale, and wastes a lot of energy. The latest electric water heater has built-in anode magnesium rod descaling device, which solves the problem that the product is easy to scale. However, the anode magnesium rod has to be replaced once every two years, causing trouble for maintenance.

Main technical components of the product: The main structure of the electric water heater product is relatively simple. The main components are heating pipe, insulation layer and liner. The main materials of the heating pipe and the insulation material are basically the same materials. So the most important part of determining the price of electric water heaters lies in the inner tank of electric water heaters.

Heating pipe: At present, the most dominant heating material on the market is the Ingle 800 heating tube, which is used by almost all well-known manufacturers. The difference lies in the position and quantity of the heating pipe. For example, Ariston, Kangquan uses two upper and lower heating pipes to make the heating even, and some use the lower heating pipe to heat up more quickly.

Insulation layer: At present, all well-known domestic manufacturers use fluorine-free foaming technology to manufacture insulation layer. The difference is in the thickness.

Liner: The highest technical content of electric water heater products is the inner tank. At present, there are three types of galvanized liners, liners and enamel liners in the domestic market. Galvanized liner: coated with curing resin, because the inner tank is in a heating environment of 70-80 ° C, the solidified tree refers to easy hydrolysis reaction, the zinc protective layer has poor anti-rust ability and short service life. Because of the low cost, the price is also low. This type of liner material has been basically eliminated. However, some small electric water heater manufacturers still use this technology. Stainless steel liner: The highest grade and longest life is the stainless steel liner. Stainless steel liners are generally made of high-quality imported materials, using advanced argon-arc welding, which can eliminate weld oxidation and have a service life of more than 10 years. However, this kind of electric water heater is relatively expensive and suitable for families with more economical advantages. Enamel liner: The mid-range is the enamel liner. It is widely used in European countries. It is made by baking a layer of inorganic ceramic glaze on ordinary steel plates. It does not rust and costs only 1/6-1/4 of the cost of stainless steel liners. If the manufacturing process is poor, the thickness of the glaze slurry attached to different parts of the gallbladder may be uneven, and the porcelain phenomenon may occur. Once the porcelain water heater liner appears, it will corrode the perforation and affect the service life of the electric water heater.

The electric water heater is selected as the inner tank: the material and thickness of the inner tank of the electric water heater and the process determine its life.

There are currently two types of electric water heaters on the market, one is a mechanical version and the other is a smart version. The PC Smart Edition allows customers to set the water temperature more accurately, making it easier to preset the start-up heating time.

Electric water heater installation precautions

While electric water heaters bring comfort and convenience to their friends, safety accidents also occur frequently. The first thing to pay attention to is the installation of the electric water heater.

1. Wall selection: The wall surface on which the electric water heater is installed should be a solid wall with a thickness of 10 cm or more. This is the first condition for ensuring the installation of the electric water heater. In addition, for large-capacity water heaters, it is also a good choice to install a water heater bracket to ensure firmness.

2, water pressure test: whether it is self-installation or factory door-to-door installation, it is recommended that you must test the water pressure. Usually the water pressure should not exceed 0.7kpa, if it is exceeded, the pressure relief valve should be installed.

3, the installation environment: Although most of the bathrooms are relatively humid, but we still require to choose a relatively dry, ventilated installation environment for electric water heaters. In addition, electric water heaters should not be installed in an environment where sunlight can be directed.

4, power supply: electric water heaters are high-power electrical products, so pay special attention to the reliability of the power supply: it is best to use the power supply with leakage protection device, and determine the grounding is good. Since most of the electric water heaters are installed by the manufacturer, it is sufficient to pay attention to these problems.

5, household power supply standards: In accordance with national standards, household power equipment power supply should use single-phase three-wire 50 Hz 220 volts AC.

The above content is the introduction of the electric heating water heaters and the precautions during the installation. For your reference, I hope to provide some help to those who want to buy electric water heaters.
