Fish Heater Alarm System Provides Protection
What does the automatic heating stop function do?
The water level in the fish tank will drop as the water evaporates. If the heating is not automatically stopped, the heating rod will dry out and cause damage.
What does the automatic heating stop function do?
If the fish tank heater detects that the water temperature in the fish tank has exceeded 95°C, it will automatically stop heating, which can effectively avoid the occurrence of "boiling fish" incidents.
One-button setting, simple operation design
Simplified design：At-A-Glance Temperature Display
There is no complicated controller, and it can be set up with just one button. The red/blue indicator light indicates different working states. The current temperature LED digital display can intuitively see whether the heating rod is heating, and "fish tank novices" can also quickly get started
Humanized design
After a power outage, the previous settings can be restored to continue running, and there is no need to worry about the fish tank losing temperature due to a circuit breaker or power outage.

We have just recently re-done our 10 gallon aquarium tank. I spent some time looking for a heater to replace the older unit we had. I finally settled on this Hegger HG163 50 W heater and after learning how to remove the lower half shell to clean the heater I began the setup. It was really simple to turn on and set the digital heater control. The temperature came up in a reasonable time and the controller indicated the tank temperature. Next, was to determine the overnight control when the home temp drops by several degrees. Checking the controller the first thing the following morning showed it reading the exact set temperature. I am very impressed with this heater and would buy another one should we set up another aquarium. There are several versions of different wattages for different sized aquarium tanks.

So far so good. They work. They are accurate. I cannot say anything yet about longevity but they are already better than topfin or aqueon.

The Hygger Aquarium Betta Heater is an efficient and reliable choice for maintaining the ideal temperature in small fish tanks. The 25W model, which is perfect for 1-5 gallon tanks, heats quickly and evenly. The removable shell design is great for easy cleaning, and the LED digital display provides clear temperature readings. The heater is well-built, durable, and safe to use in both freshwater and saltwater tanks. While it performs excellently for Betta fish, it may not be suitable for larger tanks. Overall, it's a solid product that offers good value for its price, making it a great option for smaller aquariums.
