Nowadays, there are all kinds of heaters in water heaters. The quality of the heating body mainly depends on the water quality. At present, many businesses take their own non scaling as the propaganda purpose! According to the 2012 China National Quality Inspection Report, the real service years of the water heaters certified by China's quality inspection are 8-12 years. There should be no problem.

Instant type Intelligent thermostatic water heater The working principle of the fast heating intelligent constant temperature water heater determines that the key to the quality depends on the core component heating body, and the key to the quality of heating body depends on the selected material. At present, there are two types of heaters on the market: metal heaters and non-metallic heaters. Metal heating elements include stainless steel, red copper, etc; Non metallic heating elements include quartz glass tubes, ceramics, etc.

Metal heater Electric water heater It has been used for more than a hundred years, and its technology is mature and its performance is stable. When working, the heating tube is completely immersed in water, and the heat exchange is rapidly completed depending on the excellent conductivity of the metal tube, with high thermal efficiency. The heating core of stainless steel heating element and copper heating element is the nickel chromium alloy heating wire with stable performance in the world. The only difference is that the materials of the outside and the inside are different.

The characteristics of red copper: soft, easy to stretch and form, acid resistant but not alkaline resistant. Since most of our domestic water is alkaline (more alkaline in coastal areas), it is easy to oxidize to produce copper rust, and the corrosion is more serious when high temperature heats up, which is easy to be broken down by high temperature and generate electric leakage. The pressure bearing capacity of the liner is poor, and it is easy to burst at high temperature.
