Review on 🐠 Cobalt Aquatics Neo-Therm Pro Aquarium Heater (25-200w) - Fully-Submersible, Thermostat, Thermometer, Shatterproof for Freshwater and Saltwater Tanks by Heather Joseph

UPDATE: I've had a Cobalt Aquatics Neo-Therm 50W heater for over a year now and it suddenly stopped working. The digital display works fine, but the heating element does not heat up. I emailed Cobalt Aquatics and the rep was quick to reply and said if I left him my phone number he would call back to resolve the situation. I have not heard from this representative and this company has not done anything to honor their three year warranty. Therefore, I have downgraded this product accordingly. I have several other Neo-Therm heaters that I will be keeping a close eye on and will update long-term performance information on Revain.com. I will rate each heater based on its individual characteristics to be fair to the company and their products. So far, however, I cannot give Cobalt Aquatics a good rating for customer service if they do not respond to emails regarding Cobalt Aquatics prematurely failing equipment. That's very disappointing. still new to the water market and the company has yet to prove that its products have a long shelf life. As I own several Neo-Therm heaters and a couple of submersible filters for the Cobalt Aquatics DUO 500 UV Sterilizer, I hope these products will last longer than a year or two. Whether or not they hold up, however, time will tell. Given the quality control issues with most water heaters, whether you're spending $15 or $100 on a heater. A fish farmer can buy a cheap heater that will last two decades before failing, or a very expensive heater that will fail immediately after installation. According to this aquarist, aquarium heaters are still the Achilles' heel in the hobby. To date, Neo-Therm heaters have been the best I have ever owned. They are crafted like a tank, very accurate and aesthetically pleasing to the eye. I hope they are also durable enough to last many years before needing replacement, especially given their significant cost. If so, then Cobalt Aquatic will fill a very important niche in this wonderful hobby. I hope this situation is just an isolated incident with my Neo-Therm 50 as I really like these heaters. previously found that Cobalt Aquatics customer support is lacking. Unfortunately, this is the case with many water hobby manufacturers. If I hear from Cobalt Aquatics in the near future and they live up to my 3 year warranty I will happily retract this comment regarding their customer service. Luckily, many of these companies make great products, so customer service is usually not an issue. However, fish farmers are often disappointed when in the rare event that there is a problem with one of their water components, they find their warranty is worthless because the company is not honoring it. Until now. I bought a 50 watt cobalt. Aquatics Neo-Therm heater for 7.5 gallon acrylic cube aquarium. I love the Neo-Therm style and it looks very well constructed. The heater is very easy to set up and the high tech look suits my aquarium perfectly. As for the digital heaters, I also have a few Fluval E-Series heaters that are well made and do an excellent job of heating my aquariums. However, the Fluval E-Series suffered from quality control issues (one E 300 failed after 10 months and another after almost three years when the water level in my tank exposed the top of the heater and burned out. The heater should have just turned off). Also, due to the digital microprocessor, the E Series has difficulty functioning correctly when not in a constant flow of water. This must be considered a design flaw as this heater must function both vertically and horizontally. However, when this author placed my Fluval E-Series heaters vertically, they did not work properly. However, when I placed them horizontally and directly into the flow of my filter's outlet pipe, they worked great. Regarding this design flaw, E-Series owners have posted on several occasions on the fish farmer forums about how they were forced to return their heaters because they might not be able to get them to work properly. As previously mentioned, I encountered a similar issue with my E Series heaters, which was resolved when the heaters were placed horizontally and in the flow of the filter outlet tube. This is a complex microprocessor circuit at Fluval. E-Series heaters that may interfere with proper heater operation if placed vertically instead of horizontally. The microprocessor in the E-Series simply detects insufficient water flow around the heater and prevents the heating coil from turning on. This has completely upset many E-Series owners. Neo Therm that works flawlessly and upright. It's also interesting to note that the Cobalt user manual says not to place the Neo Therm horizontally (or upside down). Another issue with Neo Therm is the use of epoxy to seal the heater. In fact, another Neo Therm heater buyer who also commented mentions a design flaw with the Marineland Stealthpro heaters, which were also epoxy sealed. The problem with the Marineland heaters was that if the heater had to be removed from the aquarium unless unplugged first, the heater housing would rupture. The author experienced this first hand when I forgot to turn off my Marineland Stealthpro 150 and the stove chassis cracked and started smoking. Having said that, I have to say that the Marineland 150 ran flawlessly for almost a year before this incident happened. As such, there is a serious design flaw in the Stealthpro series of heaters, which is why they were withdrawn from Marineland. As a general rule, it is always recommended to unplug the heater from the outlet before removing it from the aquarium. However, it can happen that the aquarist forgets to do this, which is why it is so important that the aquarium heater's automatic shut-off function works properly. Hopefully that's not a problem with Cobalt Aquatics Neo Therm. Based on my early observations, the Neo Therm is a very well built and well designed aquarium heater with a sleek, high tech aesthetic that looks great in a rimless aquarium. d pitfalls of the Fluval E Series and Marineland Stealthpro Series he should have a loyal following. And if the aquarium hobby has ever needed an improved product, it is for aquarium heaters, which for the most part leave a lot to be desired. .We hope that Cobalt has responded to this need with its Neo Therm series. The company currently offers four versions of this heater, ranging from 25W to 100W, which is good for smaller aquariums. However, they have stated that they are developing more powerful versions of the Neo Therm for larger aquariums. These heaters are not cheap. However, if they prove reliable and can last for more than a year or two, the Neo Therm will have a winner. Early impressions stay.
