1. Look at the liner

The inner tank of an electric water heater is the key to the quality of electric water heaters. A leak in the inner tank of an electric water heater means that the life of the water heater has come to an end. The service life of the inner tank of the water heater is mainly determined by the material of the inner tank and the manufacturer's anti-corrosion technology. At present, the inner tanks of electric water heaters can be roughly divided into three grades: stainless steel inner tanks, enamel inner tanks, and galvanized inner tanks.

The electric water heater adopts imported mechanical circumferential seam welding. Compared with the traditional three welds, the An Naide electric water heater uses an integral stretched inner tank with only one weld, which has better pressure bearing capacity and lower water leakage probability.

2. Security measures

Since the use of electric water heaters is related to the personal safety of consumers, safety performance must be paid attention to when choosing electric water heaters. Electric water heaters should generally have grounding protection, anti-dry burning, anti-over-temperature, anti-over-pressure devices, and high-end ones also have leakage protection, automatic disconnection without water, and additional power-off indication functions.

Even if the qualified products of regular manufacturers are equipped with anti-leakage protection devices, problems due to long use time cannot be ruled out. Therefore, in actual use, the plug must be unplugged after the water is heated, just in case. Once leakage occurs, turn off the power immediately and unplug the plug. If there is water on the ground, turn off the main switch before unplugging the plug.
