External Material:TA2 titanium alloy+Teflon-coated

This hygger aquarium heater is constructed with TA2 aviation-grade titanium alloy tubing, offering high strength and impact resistance. It is corrosion-resistant and suitable for both saltwater and freshwater aquariums. Additionally, it can withstand accidental bumps and impacts during daily use.

The submersible aquarium heater with a non-stick Teflon coating, it effectively reduces scale and water impurities buildup, ensuring heating efficiency, energy savings, and an extended service life. Paired with its hull-less design, it allows for effortless cleaning.

Internal: quartz glass+nickel-chromium wire

The internal quartz glass tube serves as an insulator, sealing the nichrome wire heating element within an isolated dry environment. This eliminates risk of water leakage or electric leakage even if the outer shell of fish tank heater is damaged.

Internally, it utilizes a high-performance nichrome wire paired with a high-thermal-conductivity quartz glass tube. It starts up quickly with high thermal efficiency, enabling rapid restoration and stabilization of water tempe at the set point, suitable for various application scenarios

Energy-Saving Rapid Heating Mode

Note: The external controller will emit a clicking sound when it starts and stops heating. This sound is not loud and is brief; it will not occur continuously.

E2 High Temperature Error Protection

Built-in temperature probe and smart chip technology, featuring an over-temperature protection accuracy of +1℃/+2℉. If overheating reaches 95℃~97℃ (35℃~36.1℃), the heater will automatically shut off and display error code E2 for safety.

Aquarium Heater Size Parameters 50W/100W Size 200W/300W/500W Size

Installation and Usage Tips

The vertical heating rod and temperature probe are fully immersed in water.

Ensure the angled heating rod and temperature probe are completely immersed in water.

Ensure that the heating rod is never exposed to air while it is plugged in.

Install the temperature probe inside the aquarium only.

COMPOSED OF 4 MATERIALS: The outermost casing of aquarium heater is made of TA2 titanium alloy and coated with Teflon to resist corrosion and scaling, extending its service life. The interior features a quartz glass tube encasing a nickel-chromium alloy heating wire, ensuring rapid, even, and stable heat release for good temperature control
EASY USE & CLEAN: The Teflon coating of submersible aquarium heater, provides a smooth surface, making it difficult for limescale and other substances to adhere. The shell-less design of this fish tank water heater makes it easy to clean
EXTERNAL CONTROLLER: Three-digit display that shows both the set temp and actual temp. Fish tank heater with a working indicator light — red when heating, green when at constant temperature. The digital display can be switched between Fahrenheit and Celsius readings. Buttons are clearly and easy operation
MANUAL TEMPERATURE CALIBRATION: If other thermometers show a significant discrepancy compared to the heater’s real-time temperature reading, use the “ADJ” button to manually calibrate the heater’s temperature offset until it matches the reference thermometer. The heater will then use this difference for water temperature detection, range is within ±5°F(°C)
HEATER PARAMETERS: Consists of a heating rod without a casing + a built-in tempe probe + an external controller, suction cup fixation. 50W for 10gal~15gal, 100W for 16gal~26gal, 200W for 26gal~40gal, 300W for 40gal~60gal, 500W for 60gal~90gal. US standard:AC 110-120V/60HZ. Temperature range: 68°F~90°F / 20°C~32°C. Power cord length: 4.92 ft + 4.92 ft. Temperature accuracy: ±2℉ (±1℃)
hygger Heater MATERIAL 1: The thermal conductivity of titanium alloy, combined with the scale-resistant advantage of the Teflon coating, ensures heat is rapidly dispersed throughout the entire aquarium, preventing localized overheating
hygger Water Heater MATERIAL 2: The sturdy TA2 titanium alloy shell is impact-resistant. It protects the internal core from accidental damage during tank cleaning or hardscape adjustments. Even under significant external impact, the internal quartz glass serves as a final, reliable line of defens
hygger Fish Heater MATERIAL 3: The quartz glass offers high thermal conductivity, efficiently transferring heat from the heating wire. Its low thermal expansion coefficient makes it highly resistant to cracking under sudden temperature changes
hygger Aquarium Water Heater MATERIAL 4: The nickel-chromium heating wire is the heart of the heater. It features stable resistance, a high melting point, and an extended lifespan, delivering fast and uniform heating performance
