Hygger 200W Submersible Aquarium Heater with Digital Controller

The hygger 200W aquarium heater is made of the most durable and stable quartz, suitable for 20-gallon to 55-gallon tanks, and ideal for use in marine saltwater and freshwater fish tanks, turtle tanks, betta tanks, and small ponds. The heater length is 11.2 inches, with a voltage of 110-120V/60Hz and a power output of 200W. It comes with a US three-pin plug and a power cord measuring 6.0 feet + 4.0 feet.

The heater is equipped with a multifunction LED controller that is easy to operate and can display the current water temperature and the set temperature. You can press the "+" or "-" button to adjust the desired temperature. The aquarium heater is designed with various safety features, including overheating protection, dry burning protection, overtemperature alarm protection, memory function, intelligent constant temperature function, and Celsius/Fahrenheit conversion.

When the water temperature exceeds 95°F, the heater will automatically stop heating, the LED will flash "HH," and a beeping sound will be emitted. The heater will resume heating when the water temperature falls below 93°F. If the heater is 5 cm above the water level, it will shut off, the LED will flash "E1," and a beeping sound will be heard. The heater will restart heating when it is fully immersed in water.

The 200W fish tank heater is made of an ABS guard, with the heating element being explosion-proof quartz and the high-temperature-resistant nickel-chromium wire with silicon carbide thermal conductivity. This ensures that the aquarium heater is stable, efficient, safe, and durable, with a longer service life and heating function. It is suitable for both freshwater and marine water environments.

If the power is interrupted, the heater will maintain the temperature settings until the power is turned on again. When the current water temperature is 1°F/1°C below the set temperature, the light will flash, and the heater will start heating. The hygger aquarium heater will always maintain the comfortable temperature for your beloved fish.

Warm tips: 1. Please immerse the heater completely in water, do not bury it in sand, and do not expose it to air dry burning. 2. When it is necessary to stop working, disconnect the power socket and wait for 15 minutes before changing the water or removing the heater. 3. The external temperature controller must be kept away from the water, as it is not waterproof. 4. We recommend that the heater be installed underwater near the water intake, either vertically or horizontally, but vertical placement doesn't take up much space. 5. Please use a wave maker or circulating pump for the fish tank, as good water circulation helps the heat generated by the heater to be evenly dispersed. 6. It is necessary to clean the heating plate regularly. If impurities are attached to the heating plate, the heating efficiency will be reduced.
