Is geothermal electric heating wire or electric heating film better? Which company in Shenyang is more authoritative?

Heating cables are generally used for home heating.

1, the cable has electromagnetic shielding, which can reduce electromagnetic radiation. No electrothermal film

2. The service life of the cable is longer than that of the electrothermal film.

3. safety: heating cable > electric heating film. Fire incidents of electric heating film are common.

4. The power attenuation of electric heating film is relatively fast.

At present, the country has not recognized the electrothermal film. I don't support or oppose it, so many talents take advantage.
