Fumak 100W Adjustable heater for 10-20 gallon tanks

Comprehensive Feature Breakdown

SUPER MINI SIZE - Compact and innovative, this aquarium heater is the shortest on the market, being just over half the length of traditional heaters! Its super short design saves space and is easy to hide while still providing full power. The temperature range is 64-93F, and it works well for 10-20 gallon tanks at 100 watts.

SUPER ACCURATE 1F - Thanks to intelligent inverter technology and built-in chips, the thermostat maintains a constant temperature accurate to 1 degree Fahrenheit. This is much more precise than traditional heaters and helps save on electricity by up to 50%.

DIGITAL DISPLAY WITH DOUBLE TEMP. READINGS - The external thermostat features a digital display showing both the current and set temperatures. Simply press the SET button to switch, and you don’t need an extra thermometer to check the temperature.

DRY RUN / OVERHEATING PROTECTION - Safety is key with this aquarium heater. It turns off automatically if the water level is too low (dry run protection) or if the water exceeds 97F (overheating protection). You can rest easy without the risk of cooking your fish!

MEMORY FUNCTION - The last setting is stored in the thermostat’s memory. After a power outage, the heater will resume from where you left off when power is restored.

EXTERNAL TEMP. SETTING, NEVER WET YOUR HANDS - Set the temperature without getting your hands wet using the external thermostat. No more using a traditional knob-controlled heater that requires touching water.

MULTIPLE USES - This versatile aquarium heater can be used in both freshwater and saltwater tanks. It's perfect not only for aquariums but also for turtle heaters, pet fountain heaters, and heating seedlings.
