SCHEGO PTC HEATERS
he novel PTC aquarium heaters are particularly energy-efficient, as their output depends on the heat extraction. If a lot of heat is extracted from the heater, it readjusts its temperature independently and increases its output. As soon as it reaches its maximum temperature, the power decreases again and hardly any current flows. Thanks to this self-regulating property, PTC heaters cannot overheat, which makes them particularly safe.
The Heaters include 1.5m of cable and an Australian power plug. They are available in 300W and 600W as elements only
