Use heating pads to maintain room temperature

Heating film is a resistive heating method that provides relatively low temperatures (compared to many traditional heating systems) over a large area. The electric heating film can be installed directly to provide floor heating, wall radiant heating and ceiling radiant heating.

These films can also be used in heating panels to produce wall or ceiling heaters.

While electrothermal films typically do not operate at high temperatures, they can provide significant energy output due to the large surface area they cover. Also due to the low temperature, undesired heat losses can be lower compared to high temperature wet heating systems with long pipe run losses from a central heating source.

Resistive heating films consist of a base film, usually made of plastic, printed or coated with resistive material and electrical contact bus bars. This is laminated or coated with another insulating film, usually similar to the substrate.

Electrical contact can be made using various types of crimp contacts that make contact with the internal bus bars through the cover film. If the operating voltage is sufficiently high, the contacts must be additionally insulated and an additional safety insulation or safety ground covering must be provided over the membrane to protect the user from electric shock in the event of damage to the installed membrane.

Because of its simple installation and easy hidden installation, it is very popular among installers. When installed under carpet with other easily removable floor coverings, the membrane can be placed or removed when required. A heating controller lets residents choose which surfaces to heat.

Films are available with different power outputs per square meter. The required power output will depend on the area covered, the insulation of the building, the required room energy input, and the desired maximum surface temperature. Many countries have regulations for maximum floor or wall temperatures. These jurisdictions may require thermostats with surface temperature sensors.

This heating system is mainly used in Asian countries such as South Korea and is considered a modern version of Ondol heating. However, these heating films have been used at high temperatures for a long time, so the requirements for materials are very high, so the use time of these heating films is limited, which means that they need to be replaced after a period of use, this heating film of best-heaters can at least be used About 3 years.

Heating film is becoming more and more popular all over the world

Generally, heating membranes powered directly from the mains are only installed under floors or on ceilings for safety reasons. Due to the potentially dangerous voltages from the mains, it is often necessary to protect against electric shock due to damage (such as nails) or water ingress. Most commonly, additional insulating silicone is added to the heating membrane, although this does not protect against impact from damage such as nails. A grounded metal bag or plate can also be used, relying on a ground leakage current ( RCD ) protector on the mains to provide protection against electrical shock due to damage.

Mains heating film may be less efficient due to the extra protective layer, but the lack of power makes these types of heating films attractive.
