Our aquarium heaters combine electronic precision, reliable monitoring, and multiple safety features to easily maintain desired water temperatures, providing a safe and healthy home for your aquatic life.

Intelligent Dual Temperature and Water Sensor System The fishkeeper aquarium heater features an intelligent LED digital display and precise temperature control. With a temperature range of 59°F to 94°F (15°C to 34°C), it offers:

• "L1" Flashing: Run-Dry Protection
• "HH" Flashing: Overheat Protection (>94°F)
• "LL" Flashing: Low Temp Protection (<59°F)
• "EE" Flashing: Temperature Sensor Failure

Simple Control Adjusting the temperature is easy with the external touch thermostat. Press the button to set the temperature in 1°F increments, and press and hold for 5 seconds to switch between °F and °C.

Safety and Reliability Certified to UL standards, our aquarium heaters provide peace of mind with features like over-voltage protection, overheat protection, and an anti-scald ABS shell. The high-waterproof IPX8 level and powerful suction cups allow for secure placement anywhere in the aquarium.

Efficient Heating and Energy-Saving Utilizing high-purity nickel-chromium heating wire and advanced electronic technology, our heaters offer intelligent frequency conversion temperature control for fast, stable, and energy-efficient heating. When the water temperature is low, the heater works at maximum power to quickly warm the surroundings. As it approaches the set temperature, the power is automatically and smoothly reduced to maintain the desired temperature.
