Experience the Innovation of Construction Heating in the 21th Century with Korea Heating’s HOT-FILM!

What is Heating Film (HOT-FILM)  

Heating Film is far-infrared ray heating element unit which is made through the following processes

1) Printing carbon paste on the base film (PET film) as a heating element
2) Printing silver paste on the carbon paste printed base film
3) Making the electrodes with copper foil
4) Finally, laminating process with carbon paste and silver paste printed PET, laminating film and copper foil booth bar.

Heating film emit far-infrared radiation evenly because carbon heating element are printed on the entire film.
Far infrared ray is not only beneficial to our health, but also feel the warmth of sunbeams.
Heating Film can be used in various ways as a heating material. It can be used for walls, ceilings, and floors.
Moreover, it has a semi-permanent product life span.

Superiority of HOT-FILM Heating System

Easy-to-install and Economical Heating System

Capable of reducing installation expenses due to an easy-to-construct/install and a short period of work.
Capable of having a fast heating effect due to a parallel structure of heating element and use of electricity.
Capable of heating partially and saving unnecessary heating expenses (Possible to adopt a central control system)
Capable of having a more capacious living space because of not needing to have a separate boiler space.

Eco-friendly and Healthy Heating System

Heating element is made of carbon, such as charcoal (activated carbon), so it gives off less electronic wave.
Far-infrared ray and anion suppress Sick House Syndrome, odor, and growth of germs.
It does not use flame, so it generates less noise, dust, and carbon monoxide.
Especially, it is perfect for facilities where children, senior citizens, and patients are.

Maintenance Cost-Saving Heating System

30% cost efficient than electric heating and over 50% cost efficient than oil boiler heating.
Simple structure and design meaning fewer product failures and maintenance costs.
For house remodeling , it is easy to remove and relocate the system.

General Installation Place of Heating Film (HOT-FILM)

Ease of installation and varied uses of Heating Film (HOT-Film)
Heating film is very easy to install, and it provides far infrared way and anion, creating healthy heating environment.
Allowing HOT-Film to be used in:

Hotel, Motel, Condominium, Academy, School, Dormitory
Studio Apartment, Office
Pension, Residence, Bungalow
Kindergarten, Nursery School, Day Care Center, Training Institute
Hospital, Oriental Medicine Clinic
Church, Mosque, Sanctuary, Buddhist Temple, Prayer house
Container steel house

Check Points of High Quality Heating Film

Heating Film
Comparison Explanation
Check Points
(PET and Laminex)
The Extent Of Shrinkage By Heat
Check the width difference between base film and laminex film.
Adhesive Strength Between PET And Laminex Film
Check of adhesive strength after separating base and laminex film
Insulation / Flame-Retardant Film

Check if insulating/flame-retardant PET film is to be used.
Transparent film - For general use or display
Milky White film - For electric & electronic use.
  / Contained insulation & Flame-retardant chips

Heat Durability Of Adhesive Substance
Check the durability of adhesive to be used in laminex film
EVA - Used a film for general heating / Heat durability of 80°C
EEA - Used a film for sauna / Heat durability of 100°C
Film Surface Condition

Check if there is any scratch of film surface or insulation damage
Check if laminating surface is rough or uneven.

Copper Foil Booth Bar  
Width Copper foil booth bar has to be fitted to the width of the product so that electric current can be supplied to silver booth bar and carbon heating element.
(If copper foil booth bar is too wide, air layer can be formed and leading electrical sparks)
The thinner copper foil, the better supply of electric current between copper foil and silver booth bar and the risk of electrical spark can be prevented.
Type Of Copper Foil A rough surface can damage the insulation of film or silver printing side, which can prevent electric conductivity that is transmitted to carbon.
Copper foil has to be a pure copper color. If there is a black line formed in copper foil booth bar, it indicates that the copper foil is a inferior product containing iron.
Carbon Heating Part & Sliver Booth Bar
Carbon Printing Side The more uniformly carbon printing side are printed, the more safe and evenly it emits heat.
Silver Booth Bar Width & Content The wider silver booth bar, a better supply of electric current is produced. The higher silver contents, a better electric current is supplied to carbon heating element, and increased heating efficiency.
Resistance Value Of Silver Booth Bar An ideal resistance value is 1Ω or less

※ The service life of heating film is dependent on adhesiveness of the film, the condition of copper booth bar, silver booth bar, and carbon printing, etc.

Precautions for Hot-Film Installation

It is advisable to keep the place of installation clean and its floor flat in order to prevent scratch, bending, or other damages of HOT-FILM.

The place to install HOT-FILM needs be free of wetness/moisture, and precautions needed not to have Hot-Film directly exposed to wetness/moisture.

Insulation coated with conductive material, such as rough insulation or silver foil, not to be used as it may damage the surface of Hot-Film during installation.

Caution should be taken not to damage the surface of Hot-Film or step on it during installation. In case of surface damaged, it has to be insulated with a thin insulating tape.

Finishing material not to be used with paint, coloring agent, or hardening adhesive that can cause transformation, discoloration, or cracks while heat transmits to finishing material.

It is advisable to decide insulating/finishing materials in consultation with installation company or experts in order to maximize the effect of heating to different installation places.

When cutting HOT-FILM and connecting it to thermostat, electricity consumption not to be above 75~80% of allowed capacity of the thermostat.

※ Calculation of Electricity Consumption : Electricity Consumption(Watt) = V²(Voltage)/R(Resistance)
※ Max. Length for Hot-Film Installation
50cm : 12~13m 80cm : 7~8m 100cm : 5~6m
