25W Small Submersible Heater

Ideal for Small Aquariums

The 25W submersible heater is perfectly suited for 1-5 gallon fish tanks. Its compact size ensures easy installation and maintenance in smaller aquariums.

Advanced Temperature Control

With a temperature control range of 59℉-93℉, this heater guarantees precise and consistent water temperature. It automatically heats up when the temperature drops below the set value by 1℉ and stops heating once the desired temperature is reached.

Built-In Thermometer and HD LED Display

Equipped with a built-in thermometer, the heater provides real-time water temperature readings on an HD LED display. A red light indicates that the heater is active, while a red light-off signifies stable temperatures. An error code is displayed if the heater encounters any faults.

User-Friendly Interface

Setting the desired temperature is simple and intuitive. Press the button until you reach your preferred temperature, and the display will flash the value three times before showing the current water temperature. You can also cycle through the full temperature range (59-93℉) by holding the button.

Safety Features

The heater includes a dry burn control system that uses advanced explosion-proof quartz heating tubes. It has dual protection against overheating and dry burning. If the heating tube runs dry, the display will show "Er" and automatically stop heating. Similarly, if the water temperature exceeds 95℉, the controller will display "EE" and stop heating.

Durable and Safe Design

Crafted from premium materials and designed scientifically, this heater is both safe and efficient. The plastic shell isolates part of the temperature, preventing scalding of fish. It is suitable for both freshwater and saltwater environments.
