Information about AQQA Durable & Intelligent Aquarium HeaterThe AQQA aquarium heater delivers a superior heating experience for your fish tank, combining rapid and efficient warming with advanced safety features and smart energy-saving technology.Premium Quality & DurabilityThis fish tank heater rod is constructed from ceramics PTC material, known for its fast thermal conductivity and high heating efficiency. Both the heater’s shell and the controller are made from heat-resistant ABS material, ensuring safe heating and a long lifespan. These premium materials guarantee a secure and lasting addition to your aquarium.Advanced Heater Protection SystemSafety is a top priority with a built-in anti-dry and over-heating protection system. If the heater rapidly exceeds the set temperature and reaches over 36∘C (96∘F), the LED screen will display a flashing “EE” to alert you. Should the heater not be fully submerged in water, the LED screen will show a flashing “Er.” These features work together to provide a consistently safe and comfortable living environment for your fish.Intelligent Heating & Energy EfficiencyThe AQQA fish tank heater utilizes automatic constant temperature heating. When the water temperature drops below your set point, it will automatically warm up. Once the water reaches the desired temperature, the heater intelligently switches to a low-power mode to maintain the water temperature within a precise 0.5∘F difference from the set temperature. This intelligent design can help reduce your electricity bill by up to 45% compared to traditional heaters.Easy & Safe OperationControlling your tank’s temperature is simple and secure with the external controller. To set the temperature, long-press the child lock button for 1-3 seconds. Then, press the temperature cycle button to adjust the temperature by 0.5∘F/C with each press. The available temperature range is 59∘F−94∘F (15∘C−34∘C). For added safety, if the controller is not operated for 3 seconds, the heater will automatically enter a child lock state, preventing accidental adjustments.Kindly Note:Always ensure the aquarium heater is completely submerged in water before plugging it in, and maintain good water circulation in the tank.After the heater stops heating, please allow it to cool down in the water for 15-30 minutes before removing it to prevent the residual temperature from potentially damaging the shell.
