Key Features
Compact Design Saves Space
This digital mini heater can be installed vertically or mounted horizontally in freshwater aquariums. It is ideal for various small turtle and fish tanks, including those of shrimp, Betta, Angelfish, Guppy, Swordfish, etc, perfectly meeting the needs of smaller tanks.
Designed For Mini Tanks
This HG083 mini heater is meticulously crafted for mini tanks, offering a secure and stable installation in any corner thanks to its robust suction cup. It can also be discreetly placed in fish tanks with a narrow, black back compartment where water pump filter materials are typically stored.
Digital Display & External Controller
The hygger 083 digital mini heater is equipped with an adjustable LED digital external controller that allows you to set the temperature within a range of 68°F to 90°F and displays the current water temperature. The controller indicates the heater’s operational status with color-coded lights: a red light signifies that the heater is actively warming the water, while a blue light indicates that the water has reached and is maintaining the set temperature.
Premium Materials for Durability
The heater’s surface is crafted from Teflon, renowned for its anti-corrosive properties and rust prevention. The outer shell is constructed with stainless steel, ensuring even heat distribution. The heater is IPX8 waterproof, thanks to its fully enclosed glue-filling technology, effectively preventing water leakage.
Safety and Anti-Burn Design
It is constructed with a nickel-chromium electric heating wire, known for its superior thermal energy efficiency. It conducts heat through quartz glass, effectively transforming electrical energy into heat, ensuring a long service life and consistent temperature distribution. The exterior comprises stainless steel and Teflon, offering a safe, explosion-proof, and anti-burn design. This material combination is also resistant to corrosion and rust, providing added protection and durability.
Automatic Temperature Regulation
The HG083 mini heater has an automatic thermostat that ceases heating when the water temperature reaches the desired level and resumes heating when the temperature drops below the set point. This intelligent constant temperature function conserves electricity and minimizes energy consumption. It also features a power-off memory function, which means there’s no need to readjust the settings after a power outage; itwill remember the last settings and resume operation accordingly.
Easy to Clean
Its shell is seamless, eliminating concerns about debris getting trapped, which is particularly beneficial for use in small fish tanks.

I just bought this for my 5.5G quarantine tank. I was surprised how small it is. I trust hygger products, so I know this is gonna do what it says it will do based on my other hygger heaters in my other tanks. This is the smallest one so far I’ve ever seen. Suction cups allow it to stick firmly and it digital reader is cool, same as all my other heaters. The only difference is once you’ve set your preferred setting, it doesn’t show it except the current temperature setting unlike my other hygger heaters bit it doesn’t matter it’s only for my quarantine tank anyway. For the price, that’s good enough for me.
I have 27 tanks and use these little heaters in all of them. They don’t take up much space at all and I can always check the temperature with the digital reading. I also like that I can set the temperature and its not a preset heater stuck on one temperature (usually 78°. I looked at alot of reviews for those type heaters and they don’t seem to hold the temperature well and they malfunction.
Like hygger , good prices
Great unit I really like the digital display.
Small and powerful. This heater can keep up with my water changes, brining 2 gallons of 55 degree water up to 76 degrees in less than an hour. The profile is modern and hidden. I would highly recommend this for anyone with a nano tank 5-9 gallons in a cooler room.
The mini heaters work amazing. With its easy to read temperature display and the quick adjustment make it a breeze to operate. Takes up a small area in aquarium and easy to hide behind decor. Currently, using in a 5 gallon and 20 gallon quarantine/ hospital tank.
