Hygger 240 Gallon Aquarium Heater

Accurate Temperature Control

Thanks to intelligent inverter technology, our aquarium heater maintains a constant water temperature with remarkable precision. The built-in chip ensures accuracy down to 0.1F, surpassing traditional heaters. The heater comes with a built-in dual temperature control system in Fahrenheit and Celsius, providing a temperature range of 63-94°F (17-34°C). Switch between these settings by long-pressing the controller's set button for 2-3 seconds.

Overheating, Low Temperature, and Dry Running Protection

Our aquarium heater offers comprehensive safety features to protect your aquatic life: - Overheating Protection: When the water temperature surpasses 93°F, an error code “HH” is displayed, and the heater stops operating. - Dry Running Protection: If the heater loses contact with water, a flashing “Auto shut off” signal triggers, and the power is cut off to prevent damage. - Low Temperature Protection: If the temperature drops below 59°F, the error code “LL” is shown, and the heater continues to operate to maintain the desired temperature.

With these multiple protections, you can be assured of safe and worry-free use of your aquarium.

Digital LED Display and External Temperature Controller

Our aquarium heater features a unique smart LED screen that is fully waterproof and clearly displays the current water temperature, set temperature, operating power, error codes, and status. A red light signals the heater's start, while a white light indicates it has stopped to maintain the set temperature. You can easily set the target temperature using the external controller by pressing the set button.

Efficient and Explosion-Proof Design

Crafted with explosion-proof quartz glass and thermally stable nickel-chromium wire, our heater efficiently transfers heat to the environment. The protective shell is made of heat-resistant ABS material, ensuring that your aquatic life remains safe from burns. Before cleaning the tank or changing water, please unplug the power and wait 10-20 minutes for the heater to cool down.

Built-in Temperature Sensor and Power-off Memory Function

The heater includes a built-in temperature sensor and a power-off memory function. This ensures that the final settings are retained even during power outages. Once power is restored, the heater resumes its previous settings. The 600W model is ideal for fish tanks up to 120 gallons, the 800W model for tanks up to 180 gallons, and the 1000W model for tanks up to 240 gallons.

These features combine to provide you with a reliable, safe, and efficient aquarium heating solution.
