Worth the money
Using the 1000W heater my 110 gal aquarium for a few weeks and it works great. I do recommend keeping a separate thermometer. As with other reviews, the thermometer on my heater is off by +2 degrees. I donât mind though. It keeps the water temp regulated within 1 degree. The digital gauge makes it easy to set the temp without having to guess. Overall, definitely recommend and would buy again.

Great heater
This is an amazing heater, super easy to use and very accurate with its digital screen. This product unfortunately did stop working for me after a year of use. I did reach out to Hygger and after a couple of back-and-forth emails Hygger did send me a replacement. The customer support was amazing and they stand behind their product. I will continue to buy other Hygger heaters as I set up new aquariums.Thank you Hygger team

Life saver for my tank!
Had an older glass heater go out and my tank dropped from 80 to 68. We purchased a Fluval from petsmart after driving 2 hours to the nearest store on a sunday. It was a 300W heater and rated for my 75G tank, however it never was able to get higher than 74.5 degrees. I ordered this heater because they didn’t have a larger one at petsmart and it came in 2 days. it was able to get the tank up to 80 in just a few hours. I like that the gage is easy to read and has a ring that alerts you to the temp conditions as it’s heating up. Even displays the watts it’s using. The temp on the gage and my tank thermometer are within a couple of points of each other. This thing is working flawlessly and looks great as well. Hoping to return the Fluval as there’s obviously an issue with its temp calibration.

Failed too soon (update)
Bought this in July 2023. Failed in January 2024. At first, I was very pleased with this 1000-watt heater. Performed as advertised. I bought it to use in a 105-gallon saltwater mixing tank. Heated the water quickly and maintained the temperature very well. Then about 2 weeks ago, I noticed my water getting too warm, and occasionally, the high temp alarm sounding. Now the heater continuously shows “LL”, and the heater never shuts off. I thought I was so impressed with this heater that I bought a second one in October 2023 for my hospital tank. I will certainly be keeping very close tabs on this one so as not to cook any expensive fish. I will write a new review on the second heater accordingly.So far so good on the second heater. I must say that Hygger reached out to me and offered me a replacement or full refund. As such, I will upgrade my review to four stars for customer service alone. Hopefully this was an anomaly and my second heater will continue working as advertised.

Get it!!
6 months-in and it’s still working great. I’m tired of losing fish to faulty heaters that fail ‘on’. Hopefully, this one lasts and will fail ‘off’ like it’s supposed to (if needed). Digital read out and ease of setting the temp is a game changer. I’ve been keeping fish nearly 50 years and I Highly recommend this heater. So much so that I bought 3 more.

Great heater
Super easy to use, got a year out of it before the temp sensor started acting up and the tank was reading way hotter than it actually was but controller did its job by shutting the power off to it and sounding the little alarm. For the price point I wonât complain with getting a year worth of use out of it.

They stand behind their products!
I purchased this heater for a new tank we called âthe worksâ canister filter, custom acrylic tank, programable led lighting (also from hygger) tho whole nine yards and its led controller looked to be the Cadillac of heaters! And it is!However after about two months of use it would not work and the alarm for out of water would not turn off. We were extremely disappointed as it went with our tank perfectly. We decided to reach out to hygger as their other products have been amazing. We were not disapointed, they worked with us responding rapidly and provided a new filter at no charge amazing customer support from an over seas niche company. I would not hesitate to purchase any hygger item especially now having dealt with their outstanding customer service

Edit: it works after all
Edit: I need to correct my original review due to user error (doh!). I had placed the heater horizontal behind a plant to hide its ugliness. Once I repositioned it vertically and placed it closer to the filter output, it worked accurately. Seems to be maintaining the temps reasonably well. But, it’s still ugly so only 3 stars.I bought this February 4 2025 as a spare to have on hand as my current heaters were getting up there in age and I didn’t want to get empty handed if one suddenly died. Today, one of my heaters did die so I plugged this one in to replace it. What a cheap piece of crap. It has no clue what the temperature really is in the aquarium. Besides that, it’s f-ing ugly with it’s big orange band around the unit and it’s giant hygger logo on the front. I tried to hide it behind a plant but it’s still super obvious. Sadly I just passed the 30-day mark so there’s no returning it now. Wish me luck with their customer service dept.

Lo compre para un acuario marino mediano de 280 litros….chulada de calentador, hace correctamente su función al calentar el agua y medir la temperatura, lo único medio malo es que solo puedo configurar la temperatura en grados Fahrenheit y no tiene opción para grados Celsius que aquà en MX es lo que tenemos, pero como tengo un termómetro alterno para medir la temperatura y este si trae ambos pues me facilita la conversión y confirmar la correcta temperatura, su tamaño es un poco grande validen el espacio a donde ponerlo y su color anaranjado hace que resalte, pero si tienen opción de colocarlo en un filtro externo fuera de la pecera seria ideal. Lo recomiendo, a mi me gusto y funciono bastante bien….calienta el agua muy rápido.
