They recognize the unique properties of the PTC heaters that make them more reliable, safer, cost-effective than traditional resistance wire-type heaters. Consider the PTC heaters compared to resistant heaters as LED light bulbs are to incandescent bulbs. They have comparable lower energy costs and longer life. Typical heating elements that use a resistance wire to generate heat, PTC heating elements are made as ceramic stones, doped with barium titanate. These manufactured ceramic stones have very unique characteristics as semiconductors whose properties can be precisely determined during their design and manufacture. PTC devices do not burn oxygen making them safer to use in controlled environments. This also makes them more energy efficient.
