Hygger HG043 1000W Submersible Smart Aquarium Heater with Digital LED Display | For Large Tanks & Ponds up to ~800 L
The Hygger HG043 1000W is a high-power submersible smart aquarium heater with a digital LED display and intelligent automatic power-off - for the largest aquariums and indoor ponds that need serious, well-controlled heat.
What size tank is the 1000W heater for?
The HG043 1000W is built for very large tanks and indoor ponds up to about 800 litres - roughly a 210-gallon tank. For the biggest or coldest setups, two heaters split across the tank are safer and heat more evenly. Aquarium heaters need about 1 watt per litre - see our wattage & size guide.
Key features
- High 1000W output for very large tanks and indoor ponds
- 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 body of water is slow to change, so a correctly sized heater is essential to recover after water changes and cold nights. See our aquarium temperature guide.
How to set up and use it
Submerge the heater near strong flow for even heat across a big volume, and set your target on the digital display. Keep a separate thermometer as a cross-check and follow our heater safety guide; two heaters at opposite ends heat a very large tank most evenly.
