Fluval E 50w Advanced Electronic Heater

UPDATE: Oct 2013Still think this is a great product. No problems at all. Easy too keep clean. Still looks like new.Currently checking with FLUVAL as I have been told this range has an auto shut off if you forget to turn the heater off when draining the tank ( does not say this on their site though). I will post another update once I have had feedback from Fluval.Original reviewThis is a great little heater keeps the water temp very stable.I have a digital thermometer probe in the tank 2 as a double check for even heat.I bought this heater after I broke my original and very basic heater by doing a 25% water change without letting it cool down or switching it off!Not even this heater will stand up to that, however the cage surrounding the heater tube would catch any glass should you make the same mistake, though its primary function is to avoid cooking you fish from close contact.The colour change backlit LCD screen is very handy and easy to ready. Red - too hot / Green - just right / blue - too cold, plus water temp in Centigrade or Fahrenheit.Adjusting the temperate is very easy in situ as well, with a simple and sturdy lever at the top of the unit.Theoretically you could get ride of your thermometer to make your tank more aesthetically pleasing through less clutter. (but best to have non electrical backup thermometer IMO in case of power cuts)The unit samples the water directly, rather its own internal temperate, to give accurate readings.Other features are:1) to be able to detect low water circulation around the unit to avoid hot and cold spots and displays a flashing screen with LF for low flow if detected. This works well e.g. if you place the heater too near a side, vegetation or the bottom..2) flashing warning if external factors raise or lower the tank temp by 3 degrees or more.The unit also comes with two fixing bracket options to allow you to back mount in your tank and and an angled bracket for corner fixing.The suckers are very strong and also adjustable so you can more accurately raise or lower the height of the unit in your tankAll in all a well thought out and well made heater.

Unfortunately the item was broken when delivered. Very poor packaging. Came in a paper envelope. And wasn't even bubble wrapped. Very poor.

Lots of bad reviews on here about heater not getting warm enough.. i just bought two and those join another 3 I already own.. Just to say i have never, but never had a problem with this model of heater and would choose this over any and all overs. It's simple it's effective and it works.. I placed the two new heaters in two different tanks and bingo.. within a couple of hours, if that it turned from blue (too cold) to green and has stayed stable ever since.. as they all do for me.It's great for when you have pet sitters.. the temp is really clear and ultra simple to see at a glance.. no guessing what the temp is.. it says.. and shows blue for too cold, green for just right and red for too hot.. I never have mine vary by more than a few degrees even in winter or summer. In some of my tanks it flashes LF for low flow as in low water flow to distribute the heat.. but this doesn't ever affect the performanceTo those who complained about the heaters not getting hot enough I'd say a) I have never had that problem and b) vital to remember that fish rarely die fast from getting a few degrees under 25 (not that i've had that happen) they might be uncomfortable but they wouldn't die.. whereas if you have a heater overheat they die within an hour..trust me I Know as the two I just bought were because I intalled another brand.. and overnight it overheated and killed my fish :(This is the ONLY model I will ever buy.. i should have stuck to my guns and bought these sooner as then I wouldn't have lost my fish :(

Really good heater and is fab with the built in thermometer, looks great set up in the tank, espec as our tank is the fluval edge tank. Only downside is I do find I have to set the temperature gauge 0.5°-1° higher than what I want the temperature of the tank to be at as it seems to struggle a little, but that could be due to all this extremely cold weather we've been having? But I can live with that. I bought the 50w one(Which is suppose to heat up to a 60l tank) and I have a 46l tank. But other that I'm really pleased with it.

Bought this for my Fluval EVO 13.5 reef tank. Included LCD displays the real time temperature which eliminates the need of an extra thermometer. Fitted in chamber 3 near the pump neatly. The temperature is maintained at a constant of 25.5 degC regardless of room temperature. Well worth it if you want an all in one solution for heating and temperature monitoring.

2 pin plug instead of 3 pin UK sentActually quite dangerous as majority 2 pin to UK plug adapters are only 1amp and your plugging a heater into it 🔥Also looked like a pre opened item as everything loose in a very squashed box... RETURNED

I’m sure this heater would of done the job but it arrived with a European 2 pinned plug on it . My original heater had packed up and I was worried about my tropical fish so ordered it knowing it would come quickly . I had to return it and ordered a different one . Luckily my fish survived !

These heaters are wonderfully compact and aesthetically pleasing. Their display is clear and easy to read, which is a definite plus. However, after using them for about two years to regulate temperatures in tanks for neo shrimp, I've noticed some drawbacks. While they look great, their accuracy falls short of what Fluval claims. Like others have mentioned, I've encountered the 'LF low flow' warning frequently, and adjusting them to the desired temperature and maintaining stability can be challenging. It's disappointing that what could have been a premium product is marred by sensor inaccuracies. I'll be swapping out the three I own for a more traditional type.
