Aquarium Portable Heater

The hygger 031 aquarium portable heater is designed for small glass or acrylic tanks with a capacity of up to 26 gallons, making it suitable for freshwater and marine environments.

Dry Run and Overheating Protection

If the water temperature reaches 93°F (34°C), the portable heater will automatically cease operation to prevent overheating. If the water level drops below the minimum required level, exposing the heater to air, the controller will display an error code “E1” and shut off to avoid damage. It will resume functioning once it is fully submerged again. Furthermore, it is programmed to cease heating once it reaches the set temperature.
