In terms of energy conservation, electrothermal?film can save a lot of electricity when it is just stalled. In the first year, its the convertion rate from electricy to heat is more than 80%. However, the fatal weakness of the electrothermal film is aging rate and the thermal rate of decline is too high. Its rate of decline is about 10%, causing the electricity consumption become increasingly larger after the one or two years. After three years, the electricity consumption will equal to that of the heating cable. Besides, with its short operation life and high failure rate, it has been phased out of the market.
Generally speaking, the effect is good. One of its advantages is that it is heated fast, easy to control and not counted as floor height when installed. However, the heating effect is also related to the thermal insulation of the house and the installation of electric heating film.
The heat conversion rate of electrothermal?film or electric heater is relatively low and easy to cause desiccation. I think the heat conversion rate of the oil filled radiator is the highest. Now there is a box that can contain water to humidify the air in the new version of the oil filled radiator.
