Fluval E Advanced Electronic Heater, 100 W

This heater was bought to replace an Interpet heater which came with my Interpet Pod 64 litre tank and had started to heat uncontrollably. I followed the instructions to the letter, placing the new Fruval e100 heater vertically (old heater was placed diagonally so this was odd for me), but after a couple of hours the temp started dropping. Eventually after a day or so, instead of 25oC it was 22oC and falling! I trawled the internet to read any forums I could find regarding this heater and found it is a very common problem with the Fruval heaters! The solution? Fully submerge it, tip it diagonally (something the instructions tell you NOT to do) and make sure there is a good flow of water around it, ie, point your filter at it. Switch it off for 1 minute, switch it back on, without pausing too long adjust the heat to max then drop it to the minimum and then reset the desired heat, in my case 25oC. This, buy the way, was alternative advice posted on a forum by a customer that had allegedly received this advice from Hagan (makers of the Fruval heater) when they got in touch desperate for answers! I thought, what the hell, i'm going to loose my fish if I dont try something. So I placed my Fruval e100 diagonally at 45 degrees, the filter is pointing at it and it is fully submerged and reset the temp as stated above. The temp started to rise from the disasterous 22 gradually thoughout the day right up the the 25oC and it hasn't fluctuated yet! You just have to play around with it in your tank to get the right flow around it and you're sorted. This worked for me and it seems a few others too. Most excellent, EXCELLENT heater! It was about to go back to the shop but glad I hunted around the forums for an answer first! Hagan need to totally rethink their instruction leaflet they supply with the heater and online or they are going to continue to have customers returning heaters to them or retailers for a replacement which may be found to be also `problematic'! Surely, cheaper to put corrective advice on their website?!!!The LED temp window is bright and easy to read (unfortuntately, it reads sideways now but hey ho...). Back light is green when temp of water matches temp you set heater at using the little orange lever at top of heater. Very easy to do. If it fluctuates by 1 full degree lower than your setting the screen turns blue. If one degree higher, the screen turns red giving you time to sort the problem. If it rises beyond 1 degree extra the red flashes. There is no red indicator light to tell you it is heating but you would very quickly know if there was a change by the temp window colour! I dont think it needs it, besides if you are bothered you can see the element glow if you peer in! From any position in my livingroom, I can see my heater is working fine. Happy bunny.

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.

I would have given this item a 5-star rating if Amazon, had not just put the item in an empty box ( No packaging inside the cardboard box). I was surprised it still worked after being in transit. Time will tell how reliable this thermostat/ heater really is. Firstly, mount the heater more towards a horizontal plane, than a verticle one (I run two ceramic power heads & it still needed to be set to 45 degrees or more). It is easy to set the very accurate temperature settings (As per the instruction leaflet). It then maintains the temperature accurately. At a glance, you can check the current temperature in the aquarium.

No problems whatsoever and temperature checked against two thermometers- very accurate.

I must say it is dead accurate and a very nice looking heater. I really love the large bright temp. it displays at all times. Easily read from a distance. The guard is also a great touch. It really looks great in tank. The first one I purchased was not working and I was upset because I really loved the look. Turns out it was cracked on delivery but Amazon replaced immediately and I am more than happy with this Fluval heater. Price was amazing for this size. Just remember to place in tank for at least 20 minutes before you plug it in. Also, setting the temp could not be easier. I mean easy!! Greatest invention. I pray it last a long time without failing since it does have high tech circuity built on board.

The media could not be loaded.  I received this product in a damaged and used condition, which was disappointing. The item clearly showed signs of white minral deposit on black plastic, and the packaging was in poor shape. I expected a new and undamaged product, so this was a letdown. I would advise caution when purchasing from this seller to avoid a similar experience.
