Schego PTC Heaters 300W-2400W

Q: What does PTC mean in practice?

The element self-regulates — it increases output when the water is cold and reduces power as the water reaches temperature, which limits energy use and prevents overheating.

Q: How do I choose a wattage?

Match your tank volume to the recommended range in the table. Step up a size if you need a bigger temperature lift or a faster heat-up.

Q: Are they suitable for seawater?

Yes — the construction is titanium, which suits both fresh water and seawater.

Q: Do I still need a thermostat?

Self-regulation is not a set-point control. The digital controller options give you an actual temperature set point via the IP67 titanium probe.

Q: How do the multi-element units work?

Several 300 W or 600 W elements run from one Aqua Logic controller to give 600, 1200, 1800 or 2400 W of output.

Q: How do they differ from the Schego Titanium heaters?

The PTC elements are slimmer at 12 mm diameter and self-regulate their output; the standard titanium elements are 25 mm and run at fixed output.

Q: What warranty applies?

Two years on all heater elements.

Self-regulating titanium heaters for fresh water or seawater in aquaculture and aquarium systems.

Product Information

Key Features

German made PTC elements with a self-regulating characteristic — output rises when more heat is needed and drops back as the water reaches temperature
Self-regulation gives inherent overheat protection and lower energy use than a fixed-output element
High-quality titanium construction, suitable for both fresh water and seawater
Available as 300 W or 600 W elements only, or pre-wired to an Aqua Logic digital controller for plug-and-play use
Multi-element assemblies give 600 W, 1200 W, 1800 W and 2400 W of heating output from a single controller
Elements ship with 1.5 m of cable and an Australian plug; controller units add 2.0 m of main power cable and an Australian plug, with an IP67 titanium-encapsulated probe
Slimmer than the standard titanium range at 12 mm element diameter, and every element carries a two-year warranty
To pick a wattage, use the recommended tank volumes in the table below — they assume a 10 °C temperature increase. If you need a bigger lift, have an uncovered or outdoor tank, or want a faster heat-up, step up a size or ask Fresh By Design for a heat-loss calculation against your volume and target temperature.
