Key Features
Suitable for Small Shallow Tank
The hygger 097 small heater, with dimensions of 4.3″ by 1.9″ by 0.9″, is designed to save space in a small aquarium. Equipped with two robust suction cups, it can be securely positioned vertically or horizontally on gravel-free aquarium bottoms, making it ideal for heating low-water-level turtle tanks.
Built-in Temperature Sensor, with 1°F Accuracy
It is equipped with an advanced chip, and the built-in temperature sensor offers heightened sensitivity and accuracy, capable of detecting temperature changes as precise as 1°F. The external temperature adjustment button allows for settings ranging from 59°F to 93°F. Once the desired temperature is set, the heater will automatically maintain a constant water temperature.
Overheating Protection
The HG097 heater is equipped with automatic out-of-water protection. It displays an ‘Er’ error code when it is not submerged in water and an ‘HH’ code when it detects overheating.
Out of Water Protection
The small heater is designed with automatic out-of-water protection. If the heater is out of water, it will display an ‘Er’ error code. Similarly, if the heater overheats, it will display ‘HH’ to alert you.
LED Temperature Display
The digital LED temperature display provides a clear on-screen view of real-time and set temperatures. The indicator light turns red to signal that the heater is actively heating and green when the desired temperature is achieved.
Power-off Memory Function
The hygger small aquarium heater will remember the temperature setting; there is no need to reset the temperature after powering off. It will reheat automatically when the power returns.
Reliable Construction
The small heater boasts reliable construction and is crafted from tough, heat-resistant, shatterproof quartz glass and reinforced with a sturdy nickel-tungsten wire. The high-quality plastic casing provides effective insulation to prevent overheating and safeguards against scalding fish and pets.

The condensed size is fantastic for a small tank. I like the easy adjustment and digital display of its thermometer.
I have 4 aquariums in various sizes plus a “hospital tank”. They all now have Hygger heaters. The small size of these heaters make for a much cleaner tank layout and detract less from the beauty of my aquarium than the heaters they replaced. I just wish they had a small heater in 200W as we keep our house pretty cold in the winter and our larger tank could use the extra power.
Works great
This heater has become our go to heater when setting up a new fish/shrimp tank . Or if we need to replace an old heater. No need to have a separate thermometer in the aquarium, as it has the accurate water temperature displayed on the heater itself. And the controls on the cord has become a must have for me. No more fumbling with a hard to adjust knob on the top of the old style heaters. And the preset heaters are just not the best option for many species of fish and shrimp. This heater simply has it all built in for easy, reliable operation.
Great response to water changes and in maintaining temperature.
Heater works great! I love the controllability and that it shows you the current water temperature
