Smith's electric water heater products appeared at the Shanghai World Expo, providing all-round water heater solutions for 23 World Expo venues, including the USA Pavilion.

2. Haier 1986 Haier group water heater company, which started to produce the first generation electric water heaters in China, has become one of the largest key enterprises in Haier group with the fastest development and specialized in designing and manufacturing water heater products. There are four production bases in the world, which are located in Haier Industrial Park in Qingdao Economic and Technological Development Zone, Wuhan Haier Industrial Park, Qingdao Jiaonan Haier Industrial Park and Chongqing Haier Industrial Park. Now it has become the largest water heater production base in Asia, with an annual production capacity of 5 million units, exported to more than 40 countries around the world and more than 20 million users worldwide. The company's main equipment is imported from Germany, Italy, Japan and other countries, many of which are networked and can be controlled remotely. The company's products include electric water heaters, gas water heaters, gas-fired dual-purpose heating stoves, solar water heaters, water softeners, water purifiers and other 12 series products, with more than 500 specifications and varieties.

Second, how to choose a kitchen water heater?

1. Selection of inner container: A reliable inner container of electric water heater is the key to the quality of electric water heater. At present, the inner container of electric water heater can be roughly divided into three grades: stainless steel inner container, high grade and long life. Stainless steel liner is generally made of imported stainless steel and advanced TIG welding, which can prevent weld oxidation and has a service life of 15 years. However, the price of this kind of electric water heater is high, which is suitable for families with relatively affluent economy. The mid-range is an enamel liner.

Widely used in some European countries, it is made by coating a layer of inorganic ceramic glaze on ordinary steel plates, which does not rust and costs only 1/6- 1/4 of that of stainless steel liners. If the manufacturing process is poor, it will lead to uneven thickness of glaze paste attached to different parts of gallbladder, and it is easy to lose porcelain. Once the porcelain is dropped, the inner container of the electric water heater will corrode and perforate, which will affect the service life of the electric water heater. This kind of electric water heater is moderate in price and suitable for ordinary families. The low-grade galvanized lining is coated with thermosetting resin. Because the inner container is in a heating environment of 70-80℃, the cured resin is easy to hydrolyze, and the rust-proof ability of the zinc protective layer is poor and the service life is short. Because of its low manufacturing cost, its price is also low.

2. Selection of safety devices: Since the use of electric water heaters is related to the personal safety of consumers, attention must be paid to safety performance when selecting electric water heaters. Electric water heaters generally have grounding protection, anti-dry-burning, anti-overtemperature and anti-overpressure devices, and high-grade ones also have leakage protection, automatic disconnection without water and additional power-off indication functions. In general, the pressure rating of the water heater liner should be 0.75MPa (different models have different ratings). When the tank pressure reaches the rated value, the overpressure protection device shall reliably and automatically open the safety valve to release pressure to ensure safety. Leakage protection devices generally require that when the leakage current reaches 15mA, the power supply can be quickly cut off within 0. 1 sec. Buy products with the Great Wall safety sign.

3. Selection of insulation 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. The main factors affecting the insulation effect are the thickness of insulation layer and the density of insulation materials. Consumers should try to choose products with thick insulation layer and high density of insulation materials, and make a comparative choice according to the manufacturer's product specifications.
