Adjustable Mini Aquarium Heater for 5-10 Gallon Fish Tanks

YOFOTHS provides high-quality aquarium equipment and services. Extensive testing and multiple inspections are a must for every product, as we strive to offer the best. Our lineup includes 10W, 20W, 30W, 50W, 100W, and 200W aquarium heaters, as well as algae scrapers and water pumps.

The aquarium heaters boast several key features. They are small in size yet powerful, designed specifically for compact fish tanks without taking up valuable space. The upgraded chip enables quick and accurate temperature sensing, ensuring the water is heated to the desired level.

An external digital controller makes operation a breeze. Simply press the SET button to adjust the target temperature in the 64-93°F range, without the need to wet your hands. The water temperature is directly displayed on the LED screen, providing intuitive monitoring.

Safety is of utmost importance. The heaters are equipped with multiple protective features. The "E1" error code indicates the unit is not fully submerged, causing it to stop heating. Once returned to complete submersion, normal operation resumes.

The "H1" overheating protection kicks in when the water temperature exceeds 95°F, automatically cutting power to prevent damage. The heater resumes work once the temperature drops below 93°F.

Proper installation is crucial for safe and effective use. When positioned vertically, the heater must be 100% submerged. Horizontal placement also requires complete water immersion. Exposing any part of the main body or having an excessively low water level can trigger the "E1" error.

Our aquarium heaters cater to a wide range of fish species, from turtles and fighting fish to guppies, goldfish, tetras, gouramis, bettas, and more. Suitable for both freshwater and saltwater environments, these reliable heating solutions ensure the ideal growth temperature for your aquatic companions.

In summary, YOFOTHS aquarium heaters combine compact size, accurate temperature control, and advanced safety features to provide a hassle-free heating solution for your fish tank. With an external digital controller, intuitive temperature display, and comprehensive protective measures, these heaters offer seamless integration and peace of mind for aquarium enthusiasts.
