1. Advantages: no oxidation when the electric heating film is heated, the service life can reach about 100,000 hours, small size, beautiful shape, fast heating, less power consumption, no pollution, no noise, heating is safer and more effective, thermal efficiency conversion is relatively high, reduce the cold radiation of the environment to the human body, heat dissipation is relatively fast, etc.;
2. Disadvantages: easy to cool quickly after power failure, can not touch water, high price, poor stability, more joints.
