Information about AQQA Versatile and Safe Quartz Aquarium Heater
This multi-functional quartz aquarium heater offers adaptable placement, precise temperature control, and essential safety features to keep your aquatic environment stable and secure.
Flexible Dual-Purpose Design
This heater provides dual-purpose functionality for your convenience. You can use it with the included protective shell and two strong suction cups to prevent accidental burns, ensuring safety for your fish and curious hands. Alternatively, the single quartz tube body with its own suction cup allows for a more compact setup, reducing space inside your tank.
Intuitive External Controller with Dual Display
The external controller with its dual digital display makes monitoring your tank’s temperature simple. It simultaneously shows both the real-time water temperature and your set temperature. Easily adjust the temperature within a range of 59℉-94℉ (15℃-34℃). For added flexibility, you can convert between Fahrenheit and Celsius by long-pressing the button for 8 seconds.
Advanced Safety Protections
Safety is paramount with this heater’s built-in protections. If the heater is more than 1.5 inches out of the water, it automatically powers off, and the digital controller displays the error code “E1”. The heater will automatically resume normal operation once fully submerged. Furthermore, it features high-temperature automatic power outage: if the water temperature exceeds 95℉ (35℃), heating stops immediately, and the controller displays the error code “HH”. The temperature display returns to normal once the water temperature drops below 94℉.
Important Usage Notes:
- For the most accurate water temperature detection, please use this heater in conjunction with a water circulation product.
- We recommend regularly disassembling and cleaning the heater tube every 1-2 weeks to ensure optimal performance.
- Always allow the heater to cool for 15 minutes in the water before removing it from the tank to prevent damage.
Set temperature 59℉-94℉/15℃-34℃
Safety Protection

Out of Water Power Off
When the heating rod exceeds the water surface by more than 1.5 inches, the power will be automatically cut off, and the digital controller will display error code E1,When the heating rod is re immersed in water, the error code automatically recovers.

Over Tmperature Alarm
When the heating rod detects that the water temperature exceeds 95 ℉ (35 ℃),The heating rod automatically loses power and detects that the water temperature is below 95 ℉ (35 ℃). The controller error code HH automatically recovers.

The heater small and exquisite volume, convenient control system. and suitable for both fish and turtle tanks.

Suitable for Freshwater or Saltwater
Using a protective shell can protect small fish and turtles from burns.
Rapid heating of nickel wire and fast thermal conductivity of silicon carbide
Thickened 1.5mm explosion-proof quartz glass is safe and reliable
If a very small volume is needed, the protective shell can be disassembled.
Small volume, security, reliability, and simple and convenient operation.
























Using this to keep water in a 5-gal bucket (water fountain for the birds, deer, etc.) from freezing. Wrapped the control module in plastic to keep it dry and put the heating element in the water. So far, so good. Even in 20 F weather, it keeps the water 54 F. Deer, birds, squarrels, racoon and opossum all come daily for a drink of clean water.
Takes a long time to get up to temp after first installation. For a couple of hours, the temp on the cord registered 10 degrees difference between the thermometer in my tank. Seems to have evened out but if it seems to start messing up I’ll report back.
It works fine and as intended, but it¡¯s a pain setting up the temperature, and I¡¯d much rather have a dial or at least two buttons to be able to change the temp.
