xOverview
Meet the hygger aquarium heater, a robust submersible heater designed for large tanks. Built with explosion-proof quartz glass and a nickel-chromium heating wire, it heats efficiently while maintaining safe operation. The external LED digital display lets you monitor both set temperatures and current readings at a glance, supporting informed decisions without guesswork.
Fast, even heating
Thanks to a rapid heating system, heating elements distribute heat evenly through the water, helping you reach target temperatures quickly and keep them steady within about one degree. This stable warmth can reduce temperature swings that stress aquatic life and support a comfortable, thriving environment.
- Explosion-proof design for reliable operation
- Accurate control within +/- 1 degree
- Wide setpoint range from 59 to 93 F on the external controller
Safety and protection
Three intelligent protectors guard both the heater and your tank. Off-water warning stops heating when not fully submerged. Overheat warning triggers auto shut-off if water temp rises beyond safe levels. Low temperature warning alerts you if water drops below the minimum, helping you stay in control.
- Off-water auto shut-off
- Overheat auto shut-off

For best accuracy, position at a 30–45 degree angle and ensure adequate water circulation.
