Tintor Submersible Aquarium Heater – 800W / 1200W with External LED Controller, PID Smart Thermostat & Auto Shutoff | Fresh & Saltwater

Maintain the perfect water temperature for your fish with the Tintor Submersible Aquarium Heater — a powerful, intelligent, and safety-focused heating solution for large freshwater and saltwater aquariums. Available in 800W (for 100–210 gallon tanks) and 1200W (for 150–300 gallon tanks), this heater is built for serious aquarium keepers who need precise, reliable temperature control at scale.

🧠 PID Smart Thermostat — Precise to ±1°F

At the heart of this heater is an external LED digital controller powered by a PID smart chip — the same technology used in industrial temperature control systems. Unlike basic bimetallic thermostats that overshoot and undershoot, the PID chip continuously calculates and adjusts heating output to maintain your target temperature with an accuracy of ±1°F. The result is a stable, consistent water temperature that protects your fish from the stress and health risks caused by temperature fluctuations.

Temperature can be set anywhere from 68°F to 93°F using a single button on the controller — simple and intuitive to operate.

📱 External LED Digital Display Controller

The external controller sits outside the tank (it is not waterproof and should not be submerged), giving you a clear, easy-to-read LED digital display that shows the current water temperature at all times. You can monitor and adjust the temperature without reaching into the tank or disturbing your fish. The controller connects to the heater via a 4ft + 5.9ft power cord, giving you flexible placement options.

🔌 Power-Off Memory Function

Power outages happen — but with this heater, you won't need to manually reset your temperature settings afterward. The power-off memory function automatically restores the heater to your previously set temperature as soon as power is restored, without any input from you. This is especially important for large tanks where temperature recovery needs to begin immediately to protect your fish.

🛡️ Multiple Safety Protection Systems

This heater is engineered with several layers of safety protection to give you complete peace of mind:

• Auto shutoff when out of water — if the water level drops and the top of the heater is exposed by more than 0.8", it automatically powers off to prevent overheating or damage
• High-temperature shutoff — automatically turns off if water temperature exceeds 95°F, preventing your fish from being harmed by overheating
• Constant temperature protection — prevents runaway heating that could "cook" your fish
• Automatic fault detection — flashing LED alerts you to any operational issues immediately
• Explosion-proof quartz tube — the heating element is made from high-quality, durable quartz that won't shatter under thermal stress
• ABS plastic protective cover — high-temperature resistant housing protects both the heater and your fish

⚡ Energy-Saving Frequency Conversion Technology

The built-in PID chip and frequency conversion heating technology make this heater up to 30% more energy-efficient than conventional aquarium heaters. Rather than cycling on and off at full power, it modulates its output to maintain temperature with minimal energy waste — saving you money on electricity over time without sacrificing performance.
