What does "self-regulating" mean? |
|
|
All materials expand and contract with temperature. We take full advantage of this basic law of physics to create the "self-regulating" nature of the STEP Warmfloor™ heating element.
When the STEP Warmfloor™ heating element is exposed to a cold temperature, on a molecular level, the conductive particles embedded in the plastic get shoved together. This creates many current paths between the bus braids, the current flows through the semi-conductive plastic, and heat is generated.
When the temperature warms up, on a molecular level, the conductive particles get spread apart. This reduces the amount of current paths between the bus braids, causing the current flow to decrease, and less heat is generated.
This "self-regulating" nature allows our heaters to respond to local conditions at the floor, providing a much more comfortable environment. The heaters will self-regulate up in heat output in front an exterior door that has been opened and closed. The heat output will decrease in locations where sunlight is warming the floor.
