Orlushy Submersible Aquarium Heater, Adjustable Fish Tahk Heater with Free Thermometer Suitable for Marine Saltwater and Freshwater

For a 20gal tank- works great! Very happy with it

performs well, heated tank very quickly

This has been right on. I would buy again.

Worked great until it didnt. I dont think it was the heaters fault... it was paired with an jackhole of a adolescent alligator snapping turtle and his feeder fish and aquatic vegetation until he was able to be released back into the wild. That said, the suction cups could work better. The size was as advertised. It was easy to clean. I liked that it had an indicator light to show when it was powered on which made it feel a little safer when trying to rehabilitate an angry little snapper. It also was pretty sturdy seeing as how it held up to the abuse of a snapper lol.

Works great!!

I love an Orlushy heater! I have them in almost all of my tanks and have for a few years. I have never had a problem with one. I do find they are off by a degree or two, so make sure you set it just a smidge lower.

Works great! Holds temp fairly consistently. Too tall for a 20gallon long tank, but that’s my fault for not checking. We made it work at a slant with no trouble!

Cheap included thermometer reads lower than actual temp. Water felt warm but showed in 70s. Also showed room temperature about 20degrees lower when I removed it for cleaning the tank. I just now placed it in ice water to check temp. It reads 26.5F and -3.5C. It should read 32/0. This is unreliable and does not have a calibration feature. I could roast my fish it I relied on this thermometer. After reading the reviews I think i will get a new heater as well since the temperature settings might be off by 3 degrees or more.

I use this water heater in a 15 gallon aquarium. It takes some time to calibrate it properly the first time I use it. Once done, it is reliable and keeps the water at more or less half a degree away from the desired temperature. This heater is very sturdy and I like the fact that it is fully submersible. Some water heaters cannot be completely submerged and this is annoying when you have a cover on the tank. Another advantage, is that for the same price, you get a digital thermometer as a bonus with the water heater. I had a traditional thermometer strip, the one that sticks to the glass. Honestly, I much prefer the digital one! You can place it wherever you want using two suction cups. The sensor being directly in the water gives me the impression of getting a more accurate reading of the temperature in my tank. The only downside is that the suction cups (2 for the water heater and 2 for the digital thermometer) take forever to hold in place. But here again, once well positioned, they don't move anymore. ----------------- Français ----------------- J'utilise ce chauffe-eau dans un aquarium de 15 gallons. Il faut un certain temps pour bien le calibrer lors de sa première utilisation. Une fois fait, il est fiable et maintient l'eau à plus ou moins un demi-degré d'écart de la température désirée. Ce chauffe-eau est très robuste et j'aime le fait qu'il soit entièrement submersible. Certains chauffe-eau ne peuvent pas être submergés complètement et c'est embêtant quand on a un couvercle sur l'aquarium. Autre avantage, pour le même prix, vous obtenez un thermomètre numérique en prime avec le chauffe-eau. J'avais une bande de thermomètre traditionnelle, celui qui colle à la vitre. Honnêtement, je préfère de loin le numérique! Vous pouvez le placer où vous voulez grâce à deux ventouses. La sonde étant directement dans l'eau me donne l'impression d'obtenir une lecture plus juste de la température de mon bac. Seul bémol, les ventouses (2 pour le chauffe-eau et 2 pour le thermomètre numérique) prennent une éternité à bien faire tenir en place. Mais là aussi, une fois bien positionné elles ne bougent plus.

This product is rated and priced well. The heater is fully adjustable and capable of incremental adjustments. It also comes with an included digital thermometer to get your tank to the desired temp. It works great! I have fancy goldfish and keep my house cool so I wanted a heater to keep the tank at a constant temp so my fish stay healthy. I am very pleased with the construction and options. The digital thermometer is around a $16 value from what I saw at the pet store so this combo was a great deal! The instructions were easy to follow as well.

I've only had this product for 2 weeks and so far so good. I received the heater in a decent time frame with no damage. Keeps the temperature of my tank pretty close to the correct temperature. This does depend on the temperature of my home as well. I have 2 thermometers to check accuracy and it seems to to be doing well. Heard good and negative reviews, as with any product, decided to purchase. I really like the size and the colour as it blends nicely with my decor in my tank. I feel the price for this heater is within range of most heaters available and not over priced. So far I am happy and feel this is a good product.

So far this heater works great. I bought the 150W even though I only have 10 gallons of water (it's a half filled 20 gallon with a waterfall). I figured since I may want to fill it up some day or eventually upgrade to a bigger tank I'd go for a higher wattage. The heater is big and bulky but feels sturdy and well-built, I'm not worried about it breaking unless I do something stupid. It did take some fiddling with the dial to get the temperature right. The dial isn't exact (which is fairly normal for aquarium heaters). I tested the free thermometer that comes with it in ice water and the thermometer is 2*F off (reading 34F instead of 32F), so don't trust that the thermometer is giving an exact temperature. I wrote -2*F on a label on the thermometer just to remind me. The thermometer's not too important for me so I figure I'll keep it at 5 stars. I'm considering buying a second one for another tank.

There isn't a lot I can say. It's a heater and it does its job well. I use it for my 5.5 gallon. Took a while to get the temperature at a perfect 80°F but eventually, I was able to set the dial to the perfect spot. It's hard to find a good reliable heater in stores so I decided to look online. I'm quite satisfied with this one. Especially for the price! Its very affordable. When I start getting into the hobby more, I'll definitely buy another (or two). The digital thermometer it came with also works well and is pretty handy. Just make sure to check the heater for any crackers or damage before use and you're good to go. I highly recommend this heater.
