1), heating film is an emerging electric heating element in recent years, it draws on the PTC and conductive coating two electric heating element features manufactured, mainly used for indoor heating and environmental temperature maintenance.
2), fast heat conduction, long service life (about 30-50 years).
3), electrical energy conversion efficiency of up to 90%, small heat loss.
Disadvantages
1), slow heating speed. 2), the heating temperature can not reach a higher value for the time being.
3), heat dissipation after power failure. Heating film industry status
1, lurking in the name of confusion, lack of standards and competition in the development of disorderly bottleneck. Publicity and advertising is a variety of words, many of which manufacturers claim that their products are the "first", "only" and "best". This reflects the unorganized and chaotic development of the thermal film industry.
2, most of the domestic heating film manufacturers do not have the floor heating system design and construction conditions, but also no cooperation with relevant enterprises to discuss the construction process and safety protection measures for their own products, but eager to push the product to the floor heating project, many of the responsible person of the enterprise, and even the heating film leakage current is equivalent to the leakage of electricity, and very laughable claiming that they have done a good job of insulation, there is no leakage current. Leakage current. (No leakage does not mean that there is no leakage current)
3, the heating film industry unfair competition is also manifested in more than self-competitive commitments, such as service life and cost.
