1. From the perspective of thickness, the electric film is relatively thin and has a large area. It can be placed on the wall or on the ceiling. The second decoration is laid under the floor. It is suitable for flattening and it is more troublesome to play with the keel. The heating cable is thicker and is generally buried between the underground concrete and the floor keel.
2. From the perspective of development technology, the heating principle of electrothermal film is complex and the technology is immature. The diaphragm ink will show obvious aging within 10 years and the use effect will be greatly reduced. This is also one of the reasons for the gradual reduction of electrothermal films in foreign countries. The advantages of heating cables are mature technology, long service life, and stable performance. The application history of over 50 years abroad is still in use.
3. From the installation point of view, each heating film of the electric heating film must be connected with two power supply wires. Not only are there more wire connectors, and the wire connectors are prone to ageing and there are problems, and these fittings are manually crimped in the field, and the level requirements of the installation personnel Higher. The heating cable is the entire cable. There is only one connector and there are few points of failure. 4. From the point of view of the place of installation, electric heating membranes have poor water resistance because of too many joints and cannot be laid in the bathroom.
5. From the aspect of thermal insulation performance, the installation power of electrothermal membrane is only about 100 watts, which is acceptable for the north. However, due to the poor insulation properties of the houses in the south, there will be a slow temperature rise and the room temperature will not reach the standard.
6. From the actual heat load, like the bathroom requires 150W/? Installation power, electric point geothermal film can not be laid. Every place in the room has a different heat load, and the heating cable can adjust the power by adjusting the density of the cable, and the electric film adjustment range is relatively small.
7. From a safety point of view, electrothermal membranes are sometimes thin in installation and inconvenient to install temperature limiters, which can cause membranes to become overheated and cause safety accidents. The limited temperature device of the heating cable thermostat controls the underground temperature. Even if the thermostat does not measure the temperature properly, the temperature of the system will not be too high.
