hygger 200W Ceramic Aquarium Heater – Auto Temp & Safety Features

Reliable heating for your aquatic world

Meet the hygger Upgrade Ceramic Aquarium Heater, a 200W submersible solution designed for both freshwater and saltwater tanks. Built with an explosion-proof ceramic element and a high-temperature resistant nickel-chromium wire, it delivers steady warmth while guarding the delicate balance of your aquatic environment. The ceramic core offers durable thermal stability, precise temperature control, and long-term energy efficiency, housed in a high-temperature resistant ABS shell that helps prevent accidental scalding of fish.

Precise, automatic temperature control

Temperature stability is at the heart of this heater. Once the water reaches the set temperature, heating stops automatically; when it falls by 1°F, it restarts. This memory-enabled design retains the last setting after power outage, making setup and daily use effortless.

• 1°F accuracy for reliable warmth
• Memory function saves settings after power loss
• External controller for easy adjustments without opening the tank

Smart safety for peace of mind

A temperature and water sensor system powers automatic safety responses. If the water level drops or heating runs too hot, the heater halts and displays an error code to prevent unsafe conditions. This helps keep your routine simple while protecting aquatic life.

• Out-of-water protection to stop heating when water is low
• Overheating protection with max temperature limit of 95°F
• Clear error codes for quick troubleshooting

Easy monitoring and broad compatibility

The heater features a built-in temperature sensor and a digital LED readout. An external controller lets you fine-tune the temperature from 64°F to 95°F without disturbing your fish. With a 200W rating, it suits tanks from about 10 to 40 gallons, in either freshwater or saltwater setups.

• Digital display shows real-time water temp
• External controller minimizes water disturbance
• Suitable for 10–40 gallon tanks in freshwater or saltwater

Simple, secure installation

Strong suction cups keep the heater anchored in place, even in tight corners. For best results, ensure the heater is fully submerged during operation, unplug before water changes, and allow it to cool for 15 minutes before handling. These simple steps support consistent performance.
