The energy level of the water heater is 1, which means that the energy saving of the product has reached the international advanced level and the energy consumption is the lowest; Grade 2 indicates that the product is more energy-efficient; Level 3 means that the product energy efficiency is the average level of China market; Level 4 means that the product energy efficiency is lower than the market average; Level 5 is the market access index of products, and products below this level are not allowed to be produced and sold.
Extended data:
Frequency conversion water heater adopts light porcelain technology, which is the latest and most advanced high-tech technology. Mainly used in national defense, aviation, satellite launch and other high-tech fields. Other technical features include:
1, safety: even if it is damaged, it will not cause any harm to human body, and the leakage current after disconnection will not exceed 10mA, which is far below the national standard; The leakage current of other heating elements is above 30mA. The leakage current of the light porcelain heater in normal operation is less than 0.03mA, which is far less than the standard of the new national standard (GB4706. 1-2005) that the leakage current value is less than 0.75mA.
2. Energy saving: the heat energy conversion rate is above 96%, while the heat energy conversion rate of other heating elements is between 68% and 73%.
3, durable: no acid corrosion, no alkali corrosion, no oxidation, no scaling.
4. Small size: under the same power, the size is only110 of other heating elements. For example: 2300W light porcelain heater, the reference size is:119mm *17mm * 4mm.
