Precautions for installing electric heat film:
3. The electric thermal film must be cut according to the cut position.
4. The electric heat film must be laid face up according to the instructions. When laying, the electric thermal film should be flat, no folds, and need to be fixed with tape to prevent overlapping of the electric thermal film.
5. When installing, the electric thermal film should be at least 30 cm away from the wall with a window.










The advantages of electrothermal film are as follows:
2. The anti-aging materials for manufacturing electric heating film are all special materials with good characteristics, ant-aging, non deterioration, stable performance and long service life.
3. The moisture resistant electric heating film is made of polyester film and is waterproof as a whole.
4. High toughness. According to testing, he tensile resistance of the electrothermal film is about 20GK.
5. Small shrinkage. In aging tests, the shrinkage rate is minimal.
6. After testing, the performance and size of the electrothermal film have not changed significantly after 26000 hours of continuous operation at a surface temperature of 40℃.
7. Fully advanced heat sealing process ensures full polymerization between membranes without bubbles or delamination, ensure a close combination of the heating element and the current carrying strip.
8. The endurance radio thermal film can operate safely in an environment of- 20℃-50℃.
9. Brownian motion produces far infrared rays.

FAQ about product:
1.Does each room require its own thermostat?
We would recommend that each room has its own heating system controlled by its own thermostat.This will allow for simple and more accurate temperature control of each room and will avoid heating rooms which do not require it.
2.Is this a safe product to put in my home or business?
Yes. All our floor heating solutions endure rigorous development and quality control testing to ensure that your floor heating system is reliable and safe.
3.Can I use Heating Film with my floor material? What if my project uses an underlayment?
Heating Film is compatible with a wide variety of floor materials like vinyl, laminate, and carpet. Let us know if you have any questions because we are here to help. One note you should keep in mind is that Heating Film is not rated for wet areas like bathrooms. Heating Film is compatible with any underlayment you would use in an installation, including a pre-attached underlayment like some vinyl floors have.
4.How do I install Heating Film? How does it all get connected?
Heating Film installs directly under a floating floor and is compatible with a variety of underlayment options. Simply lay out your underlayment and then position Heating Film above the under layment. You can also install Thermo Film under an MDF layer.Heating Film mats are then wired in parallel to a floor heating thermostat. The number of mats and layout of the room will affect the exact process of how to wire the heating mats together. Please see the Installation Manual for explicit directions or call us anytime for assistance.
5.Will this add height to my floor?
Heating Film will add up to about 1/32nd of an inch to your floor height. Depending on the type of floor coverings or the potential presence of an underlayment padding, this height may end up being negligible according to industry standards on floor height deviation allowances.
6.How does electric radiant heat work?
Electric radiant heat works by arranging conductive heating elements through your floor to provide gentle but noticeable heat traveling up from the floor, providing an efficient and luxurious effect in your home or commercial space.
7.What type of floors can be heated with ThermoSoft systems?
If you can walk on it, we can heat it! Our diverse array of underfloor heat systems can be applied under any floor covering. The key is matching the right radiant heating product with the right installation method, and of course, this is just one of the things you can call us to get help with anytime!
8.How long will ThermoFilm last? How long is the warranty?
Heating film requires no regular maintenance once installed correctly and if left undisturbed (remember your radiant system is down there when planning a remodel!). The heating mats are warrantied for 10 years, but after 17 years being on the market, we have yet to see a ThermoFilm mat fail due to old age. The thermostats that we offer are warrantied for 3 years because we only use thermostats with GFCI protection which, per national electric code, is recommended to be replaced every 3 years. Replacing a thermostat is simple, easy, and inexpensive.
