Fumak 100W Adjustable Heater for 10-20 Gallon Tanks

Super Mini Size

This aquarium heater boasts the shortest length in the market, just a bit more than half the traditional aquarium heaters! Its innovative super short design perfectly solves the layout issues for aquarium enthusiasts, taking up less space while still providing full power.

Super Accurate 1°F

Equipped with intelligent inverter technology and built-in chips, this heater maintains a constant temperature with an accuracy of 1°F, far surpassing the traditional knob-controlled heaters. This precision ensures stability and can help you save up to 50% on electricity bills.

Digital Display with Double Temperature Readings

Features an external digital thermostat offering two temperature readings: the current temperature and the set temperature. Simply press the SET button to switch. No need for an extra thermometer to measure the current temperature, saving you time and effort.

Dry Run / Overheating Protection

This heater includes multiple safety features. It automatically stops when the water level drops below the minimum level (Dry Run Protection) or when the water temperature exceeds 97°F (Overheating Protection). These safeguards prevent any potential harm to your fish.

Memory Function

The thermostat retains the last settings, meaning your heater will return to the previous set temperature after a power cut without needing any readjustments.

External Temperature Setting

Stay dry with the external thermostat, eliminating the need to touch wet surfaces to set the temperature, as is the case with traditional knob-controlled heaters.

Multiple Uses

Suitable for both fresh and marine water, this fish tank heater can be used for various applications including aquariums, turtle tanks, pet fountains, and even plant seedling heaters. Its versatility makes it an invaluable asset in your pet care setup.
