All the electrical stuff are dangerous, they should be avoided contacting with water. There is a waterproof heater in the market. It uses advanced PTC ceramic heating element which has advantages of low power consumption, light weight, and the body of it is not hot. It has a good waterproof performance. Even in the bathroom, it will not do harm to the human body, and is suitable for bathrooms and living rooms.
The electrothermal?film is waterproof. However, it is recommended that keep the chances of contacting with water at minimum. Safety first. Just in case.
The electrothermal?film is waterproof, the working performance is normal with no leakage after being soaked in water for 48 hours. So it can be used in wet environment, but insulation waterproof treatment on connecting and clipping parts should be well prepared. I am now using silicon crystal electrothermal?film of Gree. But I think that it is better avoid contacting with water, because there are wires under the silicon crystal plates. It will be short out when contacting with water, it's dangerous.
