Hygger Mini Portable Aquarium Heater

Hygger Mini Portable Aquarium Heater

Hygger Mini Portable Aquarium Heater (model HG031) is a compact submersible aquarium heater for small tanks, including nano, betta and turtle setups. It works in both freshwater and marine systems, and its small body is easy to hide so it takes up very little room in the tank.

Key Benefits

• Compact enough for small tanks where space is limited, and easy to conceal.
• Gives accurate temperature control for sensitive species such as bettas and shrimps.
• Adjustable from 15°C to 34°C (59°F to 93°F), so you can set the water to suit your livestock.
• LED digital display shows the water temperature in real time.
• External controller lets you adjust the temperature without putting your hands in the water.
• Display switches between °C and °F.
• Several built-in protection features: memory function, overheat protection and dry-run protection.
• Easy to install and operate.

Safety Features

• Memory function: retains your settings after a power outage, which is useful during load-shedding.
• Overheat protection: stops heating if the water exceeds 93°F (34°C).
• Dry-run protection: shuts the heater off automatically if it is exposed to air, and the display shows error code "E1".
• Construction: 2 mm (0.08") thickened quartz glass, resistant to explosion and corrosion, for durability and safety around aquatic pets.

How to Use

• Place the heater in the tank so it is submerged in the water. Its small size makes it easy to tuck out of sight.
• Use the external controller to set your target temperature within the 15°C to 34°C (59°F to 93°F) range, and read the water temperature on the LED display.
• Press to switch the display between °C and °F if you prefer one scale.
• If "E1" appears, the heater has detected exposure to air and has shut off automatically.

Suitable For

• Nano aquariums.
• Betta tanks.
• Turtle tanks.
• Shrimp setups, where stable, accurate temperature control matters.
• Freshwater and marine environments.
