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.

Temperature insufficient due to possible fault after seeing the product open box with no seal and partly assembled unit when I open my parcel.unfortunately had to use it due to heater fault from the original . The reviews say it is in spec on the new unit but could not keep the temperature consistent. I lost 5 fish through these issues I will not buy from this seller using used item selling as new again.

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 :(

The main reason I bought this was the built-in thermometer which allows to me easily see the temperature without relying on annoying floating thermometers which keep coming unstuck or stick-on thermometers which are difficult to read. It is also coloured coded, so at a glance I can see if the temperature is too cold/hot/or just right!It has a plastic guard around it to stop the fish coming directly into contact with it. Very handy for my Betta which for some reason likes to wrap himself around the heater.The only downside to the heater is that it has to be removed and allowed to cool completely (for at least 30 minutes) during water changes which can mean the temperature of the tank can drop quite a bit in the meantime.I use this 50W heater in a 30 litre tank at 26 degrees and once the correct temperature is established after water changes, I have never seen it go up or down!

Working as mentioned in product description.

Tengo varios de estos calentadores en los acuarios y hasta día de hoy sin problemas. Son muy muy precisos, muestra la temperatura en la pantalla lcd que tiene.Azul si la temperatura baja de la marcada, verde si está en la temperatura indicada y rojo si está por encima de la temperatura marcada. Esto es un plus, por que se ve muy cómodamente y te das cuenta de cualquier variación con solo una mirada.Además están metidos en la carcasa plastica esta para evitar quemaduras a los peces o cualquier animal que se arrime al calentador cuando está trabajando, completamente sumergibles y muy fáciles de manejar, solo hay que darle a la palanquita roja esa que tienen arriba y vas sumando o restando temperatura de medio en medio grado.

Mancano istruzioni in Italiano... Peccato

Good one

I am happy with this purchase.Most importantly, I am happy that my fish is protected from burns by the plastic cover around the heating element. The temperature in the aquarium is stable, and the heater's display looks cool.Before buying it, I was concerned before about the accuracy of the heater's thermometer. In fact, it seems to be quite accurate, and actually it helped me to learn that the strip thermometer that I had on the aquarium glass was off. (And yes, I bought a third thermometer to check which one, the strip or the heater's one, is lying).
