Built with intelligent IC chip, hygger aquarium heater have precise temperature control system (Temp Accuracy is 士 1℉/℃) and memory function. In case of a power cut, when the power recovers the heater will follow the last setting. When the water temp is over 95-97℉(35-36℃), the heater will automatically stop heating and displays E2 fault code. When the water temp reaches the set temp, green light on and it will automatically stop heating. When the water temp is lower than the set temp by 1-2℉, the heater will automatically heat up, red light on. When the water temp of the controller shows is different from the external thermometer shows, hold down the "+""-" keys for 5 seconds at the same time. Then will flash a number, press the "+ "or "-" key to increase or decrease until the temperature is calibrated to the actual water temperature. The controller is designed with a push-pull hook, which can be hung on the wall to control the temperature. The package includes: 1 * Aquarium heater with intelligent digital temperature controller and temperature sensor 3 * Suction cups，one for temperature sensing probe,two for the heater rod. 1 * User Manual Warm Tips: 1. Please immerse the heater completely in water, do not bury it in sand, and do not expose it to air. 2. The temperature sensor and heater must be completely immersed in water at the same time to work together, and the distance between the two should not be too close. 3. When it is necessary to stop working, disconnect power socket and wait for 15 minutes before changing water or removing heater. 4. Note that when the heater is exposed to air, the heater power supply must be turned off, and the dry burning time should not be too long. 5. When using the heater, make sure there is enough water circulating in the tank. 6. The external temperature controller must be kept away from the water as it is not waterproof. 7. 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. 8. Please use the wave maker or circulating pump for the fish tank. Good water circulation helps the heat generated by the heater to be evenly dispersed. 9. It is necessary to clean and clean the heating plate regularly. If impurities are attached to the heating plate, the heating efficiency will be reduced. ## Features - 100 Watts Aquarium Heater for 15-20 Gallon Fish Tank : Made of TA2 Aviation Titanium Alloy, the 100W aquarium heater is suitable for 15 to 20 gallon saltwater and freshwater fish tank.The heater voltage 110-120V/60HZ, power 50W,US three-pin plug, heater length 7.09 inch,power cord is 4.82+1.31feet.The aquarium heater comes with 2 strong suction cups,1 temperature probe with 1 suction cup,1 controller. - Rapid Heating & Safe & Durable : The heater rod made of anti-corrosion TA2 Aviation Titanium Alloy,the most stable nickel-chromium wire and anti-explosion quartz glass heating element,covered by teflon, not only can quickly and stably conduct heat to the surroundings,but also more safer for your fish.Longer service life and longer heating function.Suitable for Fresh Water and Marine Water. - Temperature Calibration Function : When the tempeture of the controller is different from the temperature of the external thermometer, can be calibrated by pressing "+""-" keys at the same time.

Wish the suction cups were more reliable but it maintains position even when it comes loose ### ⭐⭐⭐⭐⭐ Decent heaters. *by on Reviewed in the United States June 4, 2026* Decent little heaters. Kept a 14G cube stable. ### ⭐ Do not buy, will kill your fish!!! Poor temperature regulation. *by on Reviewed in the United States October 17, 2025* This thermometer does not regulate temperature accurately (if at all). I have wild temperature spikes in my aquarium. Ideally I’d like my aquarium to be 76 to 78, but if I set the heater’s thermostat to 78 I get temps in excess of 90 degrees as measured with a calibrated thermometer.I thought the heaters thermostat was just reading low, so I set the heater to 73, and for several days it’s maintained 78 as read with the calibrated thermometer.However, this morning my calibrated thermometer was 89 degrees but the heater was still saying it was 74 degrees and set for 73. The water felt much warmer than usual and there is a milky haze in the tank (likely a bacteria bloom overnight).I unplugged this heater and initiated a return. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/589880399-marine-aquarium-heater-100w-titanium-heater-with-digital-led-controller](https://www.desertcart.com.ar/products/589880399-marine-aquarium-heater-100w-titanium-heater-with-digital-led-controller) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-11-12*
