Why You’ll Love It
The hygger 019 quartz heater is designed with an intelligent thermostat that has over-temp protection, auto shut-off at 95°F, and resumes heating below 93°F for fish tanks 5–310 gallons, both freshwater and saltwater. It will adjust the power auto to save energy with rapid heating, while its power-off memory can keep the setting and resume work.
Key Features
Excellent Safety Performance
The hygger 019 quartz heater is equipped with an integrated intelligent LED digital temperature display and 3 temperature probes, allowing real-time water temperature monitoring with an accuracy of ± 1°F. Attached with a robust suction cup bracket, the heater can be securely fixed in any corner of the fish tank.

Double Quartz for Rapid Heating
Equipped with an explosion-proof quartz heating element, this quartz heater can quickly warm your tank in seconds. The nickel-chromium heating wire is crafted for superior thermal efficiency, and silicon carbide for heat conduction ensures safety and durability. The high-temperature-resistant plastic cover offers robust corrosion resistance and maintains its shape without easy deformation.
Smart Thermostat
The over-temperature protection feature safeguards against overheating in your aquarium. If the water temperature surpasses approximately 95°F, the heater will display a flashing “95” code, and the red and green lights will flash in unison. Once the temperature exceeds 93°F, the heater will automatically cease operation. When the water temperature drops below 93°F, it will resume functioning automatically.

Newly Upgraded Heater with Enhanced Safety
Prevents the issues that can arise from damage to a single or double-probe system, such as a lack of heating or overheating in aquariums. Operation is straightforward and convenient with the external controller.
Dry Running Prevention
When the heater is exposed above the water surface, it will automatically shut off power and display an ER error code. Upon exposure to air, it will show an ER fault code and automatically shut down. Once the heating rod is fully submerged in water again, the heater will restart automatically. Its power-off memory function eliminates the need to reset the settings.

Automatic Frequency for Energy Efficiency
The quartz heater can completely convert electrical energy into heat energy, ensuring energy conservation and safety. As it approaches the set temperature, it operates at 10% to 30% power, fully using thermal energy inertia to reach the desired temperature, thereby saving energy smoothly.
Usage Tips
Heating Material:
– Constructed with a nickel-chromium heating wire, double-layered explosion-proof quartz, and an ABS material outer casing for durability and safety.
Installation:
– The heater has two robust suction cup brackets that securely position it in any tank corner.
Note:
– Ensuring the heater is fully submerged in water for proper operation is essential.

I purchased this heater for my new 75 gal tank I’m setting up. Heater works as described and I’m super happy with it so far. The suction caps can come a bit loose from the weight of the heater. I’m going to modify the mounting bracket with stronger suction caps
I love this heater so much i bought another one that is 300w and that’s going into a 55 gallon when I buy it as long as they keep selling this heater I will keep buying it every time I upgrade my tanks thank you for making such great products in the second picture is the first one that i bought it’s the 150w I’ve had it for a couple of months now and have had no problems with it thank you again
Love these heaters. I’ve replaced nearly all my Eheim with these. I’ve purchased more than 20 of these now for my fish room. These are high quality and last way way longer than all other brands in my experience. Hygger makes excellent quality products that are reliable and affordable. I continue to be a repeat, satisfied customer.
Works great hods temperature very steady
Love all of hygger products just bought this to replace a heater in my 20 gallon because I did like the way it was looking there was water in it so I bought the 150w and I have no complaints about it love the fact I can see the temperature on it and I can control it with a push of the button thank you so much for this
I love its right height great price and so far im pleased with hygger products and will continue buying there products thank you so much for the things you make
