Thermo Heating Elements have produced PTC heaters for over 15 years. This patented technology is used to produce heating elements that have self-regulating properties. This means that the elements serve as their own sensor - they increase the wattage used in colder temperatures and decrease the wattage used as the temperature increases.
This occurs due to the construction. First, silver is printed on the polyester film then a carbon layer is printed on top of that. As the temperature of the heater increases, the carbon layer causes the silver layer's resistance to increase. This increase in resistance corresponds to the decrease in wattage. This results in a more efficient heating system. |
