- SUPER MINI SIZE – This aquarium heater is SUPER SHORT in length – might be the shortest heater in the market! It is only a bit more than HALF of the length of the traditional aquarium heaters! The innovative super short length perfectly solves the headache of the fish keepers on the traditional aquarium heaters! Takes up less space, easy to hide, but in full power! Temperature range is 64-93F. 100 Watt for 10 - 20 Gallon tanks.
- SUPER ACCURATE 1F – Thanks to the intelligent inverter technology, with the in-built chips the thermostat keeps the fish heater at a constant temperature at an accuracy of 1F much more accurate than the traditional knob-controlled fish heaters and you save your electricity expenses by 50%!
- DIGITAL DISPLAY WITH DOUBLE TEMP. READINGS – This fish tank heater comes with an external thermostat with digital display that shows 2 readings – the current temperature and the set temperature – very easy to switch by pressing the SET button and you save an extra thermometer for current temperature measuring.
- DRY RUN / OVERHEATING PROTECTION – Full consideration of safety. With the multiple protections this fish tank heater will stop working when the water level is lower than the minimum water level (DRY RUN PROTECTION) or when the water temperature exceeds 97F (OVERHEATING PROTECTION). You are free from ''cooking fish!
- MEMORY FUNCTION – The last setting is stored in the chips of the thermostat. In case of a power cut, when the power recovers the fish heater will follow the last setting.
