The heating principle of electric heating film heating

I regret buying hobar electric heating film, and the reviews on JD.com are all fake. I looked at the praise and bought four rooms of electric heating film, spent more than 7,000, the electric heating film under the tile shop tripped as soon as it was powered, which was caused by the unqualified product. When you buy, the merchant does not tell you that there will be a problem with the tiles, and there is a problem after the paving, and the empty opening is small, so that you can change the big one, change it or trip, and let you remove the leakage protection, which will cause a lot of safety hazards.

Heating under the floor is also not good, and each room consumes more than 30 kilowatt-hours of electricity a night, which is not what they say on the JD website at all. I hope others don't fall for it.

Electric film heating, simply put, is the use of a tool called electric heating film to help us heat, its main energy is electricity, when heating is pure resistance base for heating element. After heating, the temperature of the whole space is relatively warm. It is also relatively suitable for us to use in winter.

While electric film heating has brought great convenience to our lives, it has also brought us disadvantages. Here's a look at its pros and cons.

Electric film heating has advantages and disadvantages

1.Pros:

1) Electric film heating can help us adjust the indoor temperature at will. It keeps the temperature of each room at a constant temperature. We can adjust the room temperature at will between the set temperatures.

2) It is more convenient and economical to use electric heating film for heating, and it can also save energy. When we use it, we can start or turn it off at any time, and when we start it, it heats up relatively quickly. It is understood that it can generally be heated up in three minutes.

If you want a higher temperature, it will take about half an hour. The speed is also relatively fast.

3) When we install it, it doesn't need maintenance. Its service life is relatively long, which means that we basically do not need maintenance after installation. This is also more convenient for our lives.

4) The materials it uses are environmentally friendly and will never pollute. When it is used, it will not produce smoke and dust, and there is no noise, and its material is in line with the requirements of environmental protection. Nowadays, people are very concerned about environmental protection, so the electric heating film heating uses environmentally friendly materials.

In this way, there is no environmental impact when used.

2.Cons:

One of the biggest disadvantages of electric film heating may be that the heating effect is not particularly stable. In other words, when we use it, there will be a drop in temperature. However, this situation is not particularly serious, it will automatically adjust to the optimal temperature within a certain period of time.

For us, the impact of use will not be too great.

When winter comes, the weather will drop more severely, which makes us work or study less efficiently in the natural temperature, and the way people think of it is to use external tools to help us increase the temperature. Electric film heating is a tool that can help us achieve this. It is easy to use and is made of environmentally friendly materials.

Although the heating effect is a little unstable when using, it will not affect our normal use.

The advantages of electric heating film are basically the advantages of all electric floor heating, but there are many disadvantages of electric heating film. About fever.

Comparison of electric floor heating by cable and electric floor heating by electric heating film. First, the safety factor.

Very low, because the electric heating film only has about 200 watts to 300 watts of power per piece, and if you have a heating area of 50, you need more than 100 line source connectors. The more joints, the higher the hidden dangers, which is why the heating film is not installed in the bathroom. If it is installed in the bathroom, I guarantee that you will not use it for a day, and it will all be scrapped.

Second, there is no ground connection. As we all know, any electrical has a ground wire, a TV set, a washing machine, and electric floor heating, as a large electrical appliance, if there is no ground wire.

protection, the consequences are serious. Third, there is electromagnetic radiation.

If anyone tells you that their electric heating film doesn't radiate, that's 100% fooling you. Because people who know something about electricity know that magnetism generates electricity, and electricity generates magnetism.

The two are mutually reinforcing. If there is no electromagnetic radiation, no current will pass through, and if it does, there will be electromagnetic radiation. So, fooling you didn't negotiate, hehe.

Fourth, the power will be attenuated. Power attenuation means that each piece of electric heating film is 200 watts, 200 watts in the first year, 190 watts in the second year, and 180 watts in the third year. Because the raw material of the electric heating film is a semiconductor ink, which is generally used in petroleum and aerospace, the attenuation of semiconductors is obvious to all, and then they are used to replace it with a new one every three years.

Therefore, what they boast about is to fool the people and bully us honest people who don't understand. Fifth, it is not energy-saving. Cement cannot be laid on top of the electric heating film floor heating, so they said that there is no need to lay cement, so that the heating will be faster.

This question is true, but why many people like floor heating now, why the effect of floor heating is very comfortable, is not a problem of materials, but a problem of heating effect. Floor heating makes people feel comfortable because it is heated by far-infrared low-temperature heat radiation.

The reason for the energy saving of floor heating is that it has a heat storage layer, and it is with this heat storage layer that it will be energy-saving and comfortable. Electric heating film is not without, but their products can not be covered with cement backfill. If you don't have this layer of cement backfill, then your operating costs will be high!

Because the cement backfill is (heat storage layer) in our professional terms, why is it high, there is no need to explain it, right? Sixth, the heating effect of the electric heating film is the same as the effect of all floor heating, including water floor heating, carbon fiber electric floor heating, heating cable electric floor heating, carbon crystal electric floor heating, as long as it is floor heating, the effect does not exist that better.

Advantages of electric film heating.

1. Uniform and comfortable heat dissipation.

The heating principle of graphene electric heating film floor heating system is radiant heat transfer, compared with air conditioning, heating, etc. through forced convection circulation hot air heating, the dust flow in the air is much smaller, reducing the spread of harmful germs in the air, the indoor environment is more hygienic and clean, the floor heating system also creatively uses the characteristics of human body temperature, and the care from the feet makes you feel more comfortable and makes your home full of warmth.

2. Clean and healthy.

The floor heating system can effectively promote foot blood circulation, thereby improving the blood circulation of the whole body, promoting metabolism, and inhibiting cardiovascular diseases; It is especially suitable for the elderly and children, and has more prevention and treatment effects for patients with arthritis and cold legs. And to a certain extent, improve autoimmunity.

3. Environmental protection and energy saving.

Compared with the traditional convection heating method, the energy saving range of the floor heating system is about 30%, the heat loss of the floor heating in the transmission process is smaller, and the heat is concentrated in the height of the human body, even if the indoor set temperature is lower than the convection heating method 2 5, people can also have the same warm feeling. Floor heating can fully save energy, and will not make any noise, will not raise dust, is a very environmentally friendly and energy-saving product.

4. Beautiful and generous.

After the installation of the whole system, there is no longer an electric heating sheet in the room, which virtually increases the indoor usable area by 2% and 3%, which is not only convenient for decoration and furniture arrangement, but also saves you tens of thousands of yuan per square meter for the house price.

5. Efficient sound insulation.

At present, China's floor slabs are generally prefabricated slabs or cast-in-place slabs, and their sound insulation effect is poor, walking upstairs affects the downstairs, and graphene floor heating is used to increase the insulation layer, which has a very good sound insulation effect, can reduce noise pollution, and there is no noise in the heating process, which is conducive to the physical and mental health of the family.
