1. From the thickness point of view, the electric heating film is relatively thin, large in area, can be placed on the wall, on the ceiling, and the second decoration is laid under the floor, suitable for tiling, and the keel is more troublesome. 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 electric heating film is complicated, the technology is not mature, and the ink part of the diaphragm will obviously aging within 10 years, and the use effect is greatly reduced. This is one of the reasons why the application of electrothermal film is gradually reduced in foreign countries. The advantages of the heating cable are mature technology, long service life and stable performance. The application history of foreign countries for more than 50 years is still in use.
3. From the aspect of installation, each heating film of the electric heating film must be connected with two power supply wires. Not only the wiring connectors are many, the wire connectors are easy to age, problems occur, and these connectors are manually crimped at the site, and the level of the installation personnel is required. Higher. The heating cable is the entire cable, with only one connector and few points of failure.
4. From the point of view of the laying site, the electric heating film has too many joints, and the waterproofness is poor, and the toilet cannot be laid.
5. From the point of view of thermal insulation performance, the installation power of the electric heating film is only about 100 watts, which is acceptable for the north, but for the south, due to the poor insulation performance of the house, the heating will be slow and the room temperature will not reach the standard.
6. From the actual heat load, if the bathroom needs 150W/m2 of installation power, the electric geothermal film cannot be laid. The heat load is different in each place in the room. The heating cable can adjust the power by adjusting the cable density, and the electric heating film adjustment range is relatively small.
7. From a safety point of view, the electric heating film is sometimes inconvenient to install the temperature limiter due to the thin installation surface, which may cause the diaphragm temperature to be too high, causing a safety accident. The heating cable thermostat finite temperature device controls the underground temperature, even if the temperature measurement of the thermostat is not allowed, it will not cause the system temperature to be too high.
