Submersible Aquarium Heater for 1-40 Gallon Fish Tanks

The 25W Aquarium Heater features an explosion-proof design, utilizing quartz glass tubes and a high-temperature resistant ceramic heating core to provide fast, consistent, and evenly distributed heat. The heater is housed in V0 grade ABS flame retardant plastic, ensuring IP68 waterproof, corrosion-resistant, and high-temperature resistance for a durable fish tank heater.

Equipped with overheating and out-of-water protection, this aquarium heater will automatically stop heating if the heater head is out of the water, displaying "E1" on the controller until the heater is fully submerged. Additionally, if the water temperature exceeds 34°C/94°F, the heater will automatically stop heating and display "HH" on the controller until the water temperature drops below the threshold.

Precision temperature control is achieved through the M2 grade water sensor, which forms an accurate water temperature sensing system. The Automatic Constant Temperature Function maintains temperature accuracy within ±1°F, automatically stopping heating when the water temperature is higher than the set temperature, and restarting heating when the water temperature is lower than the set temperature.

The digital LED controller offers a temperature range of 63-94°F/17-34°C, with the ability to switch between Fahrenheit and Celsius using the setting button (long press for 5 seconds). The LED display simultaneously shows the current water temperature and the set temperature, with a red light indicating heating is in progress and a green light signifying constant temperature. The memory function automatically retains the previous setting when the heater is restarted, eliminating the need for repeated setup.

Suitable for 1-15 gallon fish tanks, this 25W fish tank heater can be widely used in freshwater and saltwater fish tanks, as well as turtle tanks and aquariums. The heater is equipped with strong suction cups on the guard, making it easy to install the aquarium heater on the tank walls or bottom without the need for additional mounting accessories.

The combination of explosion-proof design, overheating and out-of-water protection, precise temperature control, and user-friendly features makes this 25W Aquarium Heater a reliable and efficient solution for maintaining the optimal temperature in your aquatic environment. With its durable construction and versatile compatibility, this fish tank heater is a great choice for hobbyists and aquarium enthusiasts alike.
