1.K represents the meaning of thousands?

1K is a thousand silk, 24K is 24 thousand silk (24000) composition

Different K numbers represent different resistorsl

 

2.The difference between silicone and PTFE

PTFE/PFA/FEP carbon fiber heating wire

Advantages: Wear, corrosion resistance, no smell

Disadvantages: Relative to the silicone are not soft

Silicone carbon fiber heating wire

Advantages: Resistant to bending, soft

Disadvantages: There is smell

3.What is the resistance per meter?

1K=400Ohm/m, 2K=220Om/m, 3K=133hm/m, 6K=74Ohm/m, 9K=43Ohm/m, 12K=33Ohm/m, 15K=24Om/m, 18K=21Ohm/m, 24K=17Ohm/m, 36K=12Ohm/m, 48K=9Ohm/m

 

4.How to calculated power

Product power calculation:

(Voltage*Voltage)÷(resistance*length)=power

The longer the length, the smaller the power of the heating line

Precautions

The heating wire can not overlap when used! Can not cross!

Cross-over will make the heating line local temperature higher than the melting point of the protective layer, will damage the heating wire!

 

5.About installation

The normal laying power is 100-160 watts per square. Different areas can be increased or decreased according to the room's own insulation and the type of floor. The installation is very simple, we will guide the installation, the normal laying distance is 12cm.

 

6.Precautions
The carbon fiber heating wires must not cross between each other during installation and should not be touched with each other. After installation, wait until the concrete floor is fully dried and then heat to prevent the floor from being cracked and twisted due to excessive temperature rise. When using the floor heating for a long time, set the minimum temperature first, then slowly heat up for the same reason.
