Small Submersible Aquarium Heater with Temperature Controller

The aquarium heater comes in various sizes - Small, High Power, and Super Small. Automatic constant water temperature control is the key feature of this product.

To adjust the temperature, simply press the 'SET' button. Each press will increase the temperature by 1°F. The target temperature can be accurately set between 64 to 93°F. After 3 seconds of no operation, the setting is confirmed and activated. The heater will then start heating, indicated by a red light. It will automatically stop heating once the set temperature is reached, indicated by a green light.

Utilizing advanced Intelligent Frequency Conversion Technology, this heater maintains water temperature with 1°F accuracy. The heating frequency adjusts dynamically based on temperature changes, optimizing energy efficiency and reducing electricity bills by up to 49% compared to traditional heaters.

For safety, the heater is equipped with out-of-water and overheating protection features. If the heater is not fully submerged or the water exceeds 95°F, the power will be cut off automatically to prevent damage to the aquarium inhabitants. Error codes 'E1' and 'H1' will be displayed respectively in these scenarios. The heater will resume normal operation once the issue is resolved.

The heater is available in various wattages to suit different aquarium sizes: 25W for 1-5 gallons, 50W for 3-10 gallons, 100W for 8-20 gallons, and 200W for 15-40 gallons. This 50W model is perfect for mini 3-10 gallon fish tanks, with a compact design that takes up minimal space and is easy to hide in the tank.

The external temperature controller allows for easy temperature adjustment without getting your hands wet. The digital LED display provides clear temperature readouts, and the built-in thermometer ensures accurate monitoring. Intelligent indicator lights, green for no heating and red for heating, provide visual status.

The heater remembers your temperature setting, so you don't need to reset it after a power outage. Strong suction cups make installation simple, but require monthly cleaning to maintain grip and prevent the heater from falling.

Before installation, inspect the glass tube for any cracks. If the tube is cracked, even if not completely broken, do not use the heater. Proper placement is also crucial - position the heater in the water flow path, but do not bury it. Disconnect power and wait 15 minutes before servicing the aquarium or removing the heater.

Overall, this aquarium heater provides precise temperature control, safety features, and energy-efficient performance in a compact, easy-to-use design - the perfect choice for small to medium-sized fish tanks.
