About this item
- Heavy-Duty PTC Ceramic Heating – Fully ceramic, explosion-proof heater designed for 300–800L aquariums. Provides long-term stability and safety compared to quartz glass models.
- External Digital LED Thermostat – Displays live and set temperatures with ±0.5°C precision. Auto memory function restores previous settings after power loss.
- Triple Protection System – Dry-run shut-off, over-temp protection and constant temperature regulation safeguard both aquatic life and equipment.
- High Efficiency & Energy Saving – PTC core warms large volumes of water 20% faster and consumes up to 30% less energy than traditional submersible heaters.
- Freshwater Focused Design – Ideal for freshwater tanks and most low-salinity aquariums. Not intended for high-salinity marine environments due to potential PTC core corrosion.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
