Hygger Nano Aquarium Heater 20W

Hygger Nano Aquarium Heater 20W

The Hygger Nano Aquarium Heater 20W is a compact, fully submersible aquarium heater for nano tanks, including betta tanks, shrimp habitats, nano reefs and shallow turtle setups. It has an external digital controller and built-in safety protection. That makes it a practical choice if you want to adjust the temperature without putting your hands in the water.

Key Benefits

• Safety alerts and auto shut-off: dry-run protection and an overheat guard switch the heater off if the water level drops too low or the unit overheats.
• Clear warnings: audible alarms and LED error codes ("Er", "EE" and "EU") alert you to a problem straight away.
• Adjustable temperature control: set any temperature from 15 to 34°C (59 to 93°F) on the external digital controller.
• Easy to read: a real-time LED display and indicator lights show the heating status at a glance.
• Compact, low-profile body: at just 10 cm (4") long, it fits neatly into small tanks and tight spaces.
• Auto-memory function: after a power outage, the heater remembers your last temperature setting. This is useful during load-shedding, when sensitive livestock need steady care.
• Quartz glass construction: the waterproof quartz glass body resists cracking and corrosion.
• Quiet operation: it runs quietly, so it suits tanks in bedrooms and offices.

How to Use

• The heater is fully submersible. Mount it vertically or horizontally with the included suction cups.
• For best results, place it at least 12 cm (5") below the water surface.
• Choose an area with good water circulation.
• Use the external digital controller to set your target temperature, and check the LED display and indicator lights to see the heating status.
• If an alarm sounds or an error code ("Er", "EE" or "EU") appears, check the water level and the unit.
