Smart Submersible Heater for Aquariums Up to 220 Gallons

🌞 Accurate Temperature and UltraSafe Protection
This upgraded aquarium heater is a fully-electronic high-quality device. Advanced water sensors and IC chips, combined with a PID precision electronic algorithm, ensure accurate temperature control within ±1℉. Built-in multiple safety functions, including run-dry, overheat, and low temp protection, intelligently monitor the temperature at all times, providing maximum safety. Rest assured; you won't have to worry about overheating your fish!

🌞 Intelligent Frequency Fast Heating
Made of high-purity nickel-chromium heating wire, this heater uses electronic technology to achieve intelligent frequency conversion for temperature control. This results in ultra-fast heat conduction, providing more stable and energy-efficient performance. As water temperature drops, it automatically adjusts to the highest power, quickly and stably heating the surroundings. When the temperature approaches the set point, it smoothly reduces power to maintain a constant temperature.

🌞 Enhanced Explosion-Proof
This submersible water heater is crafted from thickened explosion-proof quartz glass. The high-density silicon carbide sand filler inside the tube ensures even heat distribution and effective prevention of electric leakage. A pretty anti-scald shell design provides protection against accidental damage while safeguarding delicate aquarium inhabitants. Perfect for aquarists who prioritize the beauty and safety of their tanks.

🌞 LED Display and Easy to Use
The heater features an upgraded LED backlight temperature display with indicator lights, allowing clear real-time observation of the heating status and water temperature. An external touch thermostat provides cyclic temperature adjustment from 59℉ to 94℉ (15℃ to 34℃), with switchable ℉/℃ units for ease of use. The device can be easily positioned vertically or horizontally using 4 powerful suction cups.

🌞 Quality Assurance
Equipped with a 300W power output and featuring a 5.9FT + 4FT lengthened cable (U.S. UL certified), this heater is ideal for 40~80 gallon water tanks. Each heater undergoes our computer-assisted testing to ensure the highest operational precision before being dispatched. Your satisfaction and trust are our top priorities, and we are committed to being there for you whenever you need us.
