The Hygger HG043 800W is a powerful submersible smart aquarium heater with a digital LED display and intelligent automatic power-off - built to hold a stable temperature in large aquariums where smaller heaters can't keep up.
What size tank is the 800W heater for?
The HG043 800W is sized for large aquariums up to about 600 litres - roughly a 160-gallon tank or a 5 ft aquarium. For very large or cold-room setups, many keepers run two heaters so a single failure can't leave the tank cold or overheated. Aquarium heaters need about 1 watt per litre - see our wattage & size guide.
Key features
- High 800W output for large tanks
- Digital LED display with adjustable temperature control
- Intelligent automatic power-off safety system
- Memory function retains your setting after a power cut
What temperature should you set?
Most tropical fish thrive at a steady 24-28°C. A large tank holds heat well but still needs a correctly sized heater to recover after water changes and cold nights. See our aquarium temperature guide for the ideal setting.
How to set up and use it
Submerge the heater near strong flow (a filter outlet or wavemaker) for even heat across a big tank, and set your target on the digital display. Keep a separate thermometer as a cross-check and follow our heater safety guide; on large tanks, two heaters at opposite ends heat most evenly.
Why choose Hygger?

Frequently asked questions
Are Hygger heaters any good? Is Hygger a reliable brand?

What size tank is the 800W good for?
Large tanks up to about 600 litres (~160 gallons, a 5 ft tank).
Should I use two heaters on a big tank?
On large or valuable tanks, yes - two heaters heat more evenly and one failure can't cook or chill the tank.
How do I set the temperature?
Use the digital LED display to set and read your target; it remembers the setting after a power cut.
How do I know it's working?
The display shows the current temperature and the heater cycles to hold it - confirm with a separate thermometer.
How many watts does a large tank need?
About 1 watt per litre - so 800W suits roughly a 600 litre tank, more in cold rooms.
