The most important thing to buy an electric water heater is safety and power saving.
◆ What is the most important thing about electric water heaters?
The inner container is the key of electric water heater, and the treatment of the inner surface of the product is very important, which is the main basis for determining the warranty period of electric water heater. At present, the electric water heaters sold in shopping malls mainly have the following three kinds of liners: oxygen-free copper liner electric water heaters, which have incomparable good characteristics when applied to instant electric water heaters: fast heat conduction, pressure and corrosion resistance, good ductility, good antibacterial and bacteriostatic effects, etc. Oxygen-free copper heating system is widely used in instant electric water heaters in developed areas in Europe and America, and most international brands use red copper to produce heaters for instant electric water heaters. The special physical and chemical characteristics of copper have the characteristics of fast and stable heating and high thermal efficiency. It is internationally recognized as the most mature and stable heater in the instant water heater industry. The electric water heater with stainless steel liner is made of good material, which is not easy to rust, but the hidden danger of weld is not easy to find. After many times of thermal expansion and cold contraction, chromium in stainless steel will be corroded by chloride ions in tap water, and it may leak at the weld after a long time. Enamel liner, the enamel on the surface of the liner is non-metallic material, which does not rust and is corrosion-resistant. The inner container body is made of thick steel plate, which has strong compression resistance. Among them, the high glaze ladle liner has the best anti-corrosion and heat preservation performance and longer service life. Consumers can choose electric water heaters with enamel liners, and most manufacturers promise to replace them for more than five years.
◆ Power-saving measures for electric water heaters
The shower temperature in the electric water heater should be set reasonably, generally between 60-80℃, and the start-stop time should be determined according to actual needs. The use of electric water heaters should try to avoid the peak hours of electricity consumption. In summer, you can lower the thermostat and switch to shower instead of bath, which can reduce the cost by two-thirds. If hot water is often used at home every day, and the electric water heater has a good insulation effect, then the electric water heater should always be energized and set in the insulation state, because it takes less electricity to keep warm one day than to heat a box of cold water to the same extent. This not only facilitates the use of hot water, but also achieves the purpose of saving electricity.
